'''''Narcissus''''' is a [[Biology:Genus|genus]] of predominantly spring flowering [[Biology:Perennial plant|perennial]] plants of the amaryllis family, [[Biology:Amaryllidaceae|Amaryllidaceae]]. Various common names including '''daffodil''',<ref group="Note">The word "daffodil" is also applied to related genera such as ''[[Biology:Sternbergia|Sternbergia]]'', ''[[Biology:Ismene (plant)|Ismene]]'' and ''[[Biology:Fritillaria meleagris|Fritillaria meleagris]]''. It has been suggested that the word "Daffodil" be restricted to the wild species of the [[Place:British Isles|British Isles]], ''[[Biology:Narcissus pseudonarcissus|N. pseudonarcissus]]''. {{harv|Halevy|1985|loc= Rees A. R. Narcissus pp. 268–271}}</ref> '''narcissus''' and '''jonquil''', are used to describe all or some members of the genus. ''Narcissus'' has conspicuous flowers with six petal-like [[Biology:Tepal|tepal]]s surmounted by a cup- or trumpet-shaped corona. The flowers are generally white and [[Yellow|yellow]] (also orange or pink in garden varieties), with either uniform or contrasting coloured tepals and corona.

''Narcissus'' were well known in ancient civilisation, both medicinally and botanically, but were formally described by [[Biography:Carl Linnaeus|Linnaeus]] in his ''[[Biology:Species Plantarum|Species Plantarum]]'' (1753). The genus is generally considered to have about ten sections with approximately 36 species. The number of species has varied, depending on how they are classified, due to similarity between species and hybridisation. The genus arose some time in the Late [[Earth:Oligocene|Oligocene]] to Early Miocene epochs, in the Iberian peninsula and adjacent areas of southwest Europe. The exact origin of the name ''Narcissus'' is unknown, but it is often linked to a Greek word (ancient Greek ναρκῶ narkō, "to make numb") and the myth of the [[Philosophy:Narcissus (mythology)|youth of that name]] who fell in love with his own reflection. The English word "daffodil" appears to be derived from "[[Biology:Asphodelus|asphodel]]", with which it was commonly compared.

The species are native to meadows and woods in southern Europe and North Africa with a centre of diversity in the Western Mediterranean, particularly the Iberian peninsula. Both wild and cultivated plants have naturalised widely, and were introduced into the Far East prior to the tenth century. Narcissi tend to be long-lived bulbs, which propagate by division, but are also insect-pollinated. Known pests, diseases and disorders include viruses, fungi, the larvae of flies, [[Biology:Mite|mite]]s and [[Biology:Nematode|nematode]]s. Some ''Narcissus'' species have become extinct, while others are threatened by increasing urbanisation and tourism.

Historical accounts suggest narcissi have been cultivated from the earliest times, but became increasingly popular in Europe after the 16th century and by the late 19th century were an important commercial crop centred primarily in the Netherlands. Today narcissi are popular as cut flowers and as ornamental plants in private and public gardens. The long history of breeding has resulted in thousands of different [[Biology:Cultivar|cultivar]]s. For horticultural purposes, narcissi are classified into divisions, covering a wide range of shapes and colours. Like other members of their family, narcissi produce a number of different [[Chemistry:Alkaloid|alkaloid]]s, which provide some protection for the plant, but may be poisonous if accidentally ingested. This property has been exploited for medicinal use in traditional healing and has resulted in the production of [[Chemistry:Galantamine|galantamine]] for the treatment of [[Medicine:Alzheimer's disease|Alzheimer's dementia]]. Long celebrated in art and literature, narcissi are associated with a number of themes in different cultures, ranging from death to good fortune, and as symbols of spring.

The daffodil is the national flower of Wales and the symbol of cancer charities in many countries. The appearance of wild flowers in spring is associated with festivals in many places.

===General===
''Narcissus'' is a genus of [[Biology:Perennial|perennial]] herbaceous [[Biology:Bulb|bulb]]iferous geophytes, which die back after flowering to an underground storage bulb. They regrow in the following year from brown-skinned ovoid [[Biology:Bulb|bulb]]s with pronounced necks, and reach heights of {{convert|5|–|80|cm}} depending on the species. Dwarf species such as ''N. asturiensis'' have a maximum height of {{convert|5|–|8|cm}}, while ''[[Biology:Narcissus tazetta|Narcissus tazetta]]'' may grow as tall as {{convert|80|cm}}.<ref name=Tazetta/>{{sfn|Hanks|2002|loc=[https://books.google.com/books?id=4_kH_BffGDgC&pg=PA1 Hanks, "The biology of ''Narcissus''"], pp. 1–29}}

The plants are [[Biology:Glossary of botanical terms#S|scapose]], having a single central leafless hollow flower [[Biology:Plant stem|stem]] (scape). Several green or blue-green, narrow, strap-shaped leaves arise from the bulb. The plant stem usually bears a solitary flower, but occasionally a cluster of flowers ([[Biology:Umbel|umbel]]). The flowers, which are usually conspicuous and white or yellow, sometimes both or rarely green, consist of a [[Biology:Perianth|perianth]] of three parts. Closest to the stem (proximal) is a [[Biology:Petal#Variations|floral tube]] above the [[Biology:Ovary (botany)|ovary]], then an outer ring composed of six [[Biology:Tepal|tepal]]s (undifferentiated sepals and petals), and a central disc to conical shaped corona. The flowers may hang down (pendant), or be erect. There are six [[Biology:Pollen|pollen]] bearing [[Biology:Stamen|stamen]]s surrounding a central style. The [[Biology:Ovary (botany)|ovary]] is inferior (below the floral parts) consisting of three chambers (trilocular). The [[Biology:Fruit|fruit]] consists of a dry capsule that splits (dehisces) releasing numerous black [[Biology:Seed|seed]]s.{{sfn|Hanks|2002|loc=[https://books.google.com/books?id=4_kH_BffGDgC&pg=PA1 Hanks, "The biology of ''Narcissus''"], pp. 1–29}}

The bulb lies dormant after the leaves and flower stem die back and has contractile [[Biology:Root|root]]s that pull it down further into the soil. The flower stem and leaves form in the bulb, to emerge the following season. Most species are dormant from summer to late winter, flowering in the spring, though a few species are autumn flowering.{{sfn|Hanks|2002|loc=[https://books.google.com/books?id=4_kH_BffGDgC&pg=PA1 Hanks, "The biology of ''Narcissus''"], pp. 1–29}}

===Specific===
====Vegetative====
; Bulbs :
The pale brown-skinned ovoid [[Biology:Tunica|tunicate]] '''[[Biology:Bulb|bulb]]s''' have a membranous tunic and a corky stem (base or basal) plate from which arise the adventitious [[Biology:Root hair|root hair]]s in a ring around the edge, which grow up to 40&nbsp;mm in length. Above the stem plate is the storage organ consisting of bulb scales, surrounding the previous flower stalk and the terminal [[Biology:Bud|bud]]. The scales are of two types, true storage organs and the bases of the foliage leaves. These have a thicker tip and a scar from where the leaf lamina became detached. The innermost leaf scale is semicircular only partly enveloping the flower stalk (semisheathed).(see Hanks Fig 1.3). The bulb may contain a number of branched bulb units, each with two to three true scales and two to three leaf bases. Each bulb unit has a life of about four years.{{sfn|Hanks|2002|loc=[https://books.google.com/books?id=4_kH_BffGDgC&pg=PA1 Hanks, "The biology of ''Narcissus''"], pp. 1–29}}{{sfn|Okubo|Sochacki |2012|p=[https://books.google.com/books?id=5B-ucdbgA3wC&pg=PA104 104]}}

Once the leaves die back in summer, the roots also wither. After some years, the roots shorten pulling the bulbs deeper into the ground (contractile roots). The bulbs develop from the inside, pushing the older layers outwards which become brown and dry, forming an outer shell, the tunic or skin. Up to 60 layers have been counted in some wild species. While the plant appears dormant above the ground the flower stalk which will start to grow in the following spring, develops within the bulb surrounded by two to three deciduous leaves and their sheaths. The flower stem lies in the axil of the second true leaf.{{sfn|Hanks|2002|loc=[https://books.google.com/books?id=4_kH_BffGDgC&pg=PA1 Hanks, "The biology of ''Narcissus''"], pp. 1–29}}

; Stems :
The single leafless '''Plant stem stem''' or scape, appearing from early to late spring depending on the species, bears from 1 to 20 blooms.<ref name=RHSAZ/> Stem shape depends on the species, some are highly compressed with a visible seam, while others are rounded. The stems are upright and located at the centre of the leaves. In a few species such as ''[[Biology:Narcissus hedraeanthus|N. hedraeanthus]]'' the stem is oblique. The stem is hollow in the upper portion but towards the bulb is more solid and filled with a spongy material.{{sfn|Straley|Utech|2003}}

; Leaves :
''Narcissus'' plants have one to several basal '''leaf leaves''' which are linear, ligulate or strap-shaped (long and narrow), sometimes channelled adaxially to semiterete, and may (pedicellate) or may not (sessile) have a [[Biology:Petiole (botany)|petiole]] stalk.{{sfn|Kubitzki|1998|loc=[https://books.google.com/books?id=FyPVYzL76sMC&pg=PA100 Narcissus], pp. 100–101}} The leaves are flat and broad to cylindrical at the base and arise from the bulb.{{sfn|Sell|Murrell|1996|loc=[https://books.google.com/books?id=pKGlBap0FRYC&pg=PA285 Narcissus. p. 285]}} The emerging plant generally has two leaves, but the mature plant usually three, rarely four, and they are covered with a [[Biology:Cutin|cutin]] containing [[Biology:Cuticle|cuticle]], giving them a waxy appearance. Leaf colour is light green to blue-green. In the mature plant, the leaves extend higher than the flower stem, but in some species, the leaves are low-hanging. The leaf base is encased in a colorless sheath. After flowering, the leaves turn yellow and die back once the seed pod (fruit) is ripe.{{sfn|Hanks|2002|loc=[https://books.google.com/books?id=4_kH_BffGDgC&pg=PA1 Hanks, "The biology of ''Narcissus''"], pp. 1–29}}

Jonquils usually have dark green, round, rush-like leaves.<ref>{{cite web |title=Narcissus jonquillan |work=Missouri Botanical Garden Plant Finder |url=http://www.missouribotanicalgarden.org/PlantFinder/PlantFinderDetails.aspx?taxonid=275814&isprofile=0&z=5 |access-date=July 6, 2018 |archive-url=https://web.archive.org/web/20180707005941/http://www.missouribotanicalgarden.org/PlantFinder/PlantFinderDetails.aspx?taxonid=275814&isprofile=0&z=5 |archive-date=July 7, 2018 |url-status=live |df=mdy-all}}</ref>

====Reproductive====
; Inflorescence :
The '''inflorescence''' is scapose, the single [[Biology:Plant stem|stem]] or scape bearing either a solitary flower or forming an [[Biology:Umbel|umbel]] with up to 20 blooms.<ref name=RHSAZ/> Species bearing a solitary flower include section ''Bulbocodium'' and most of section ''Pseudonarcissus''. Umbellate species have a fleshy racemose [[Biology:Inflorescence|inflorescence]] (unbranched, with short floral stalks) with 2 to 15 or 20 flowers, such as ''[[Biology:Narcissus papyraceus|N. papyraceus]]'' (see illustration, left) and ''[[Biology:Narcissus tazetta|N. tazetta]]'' (see Table I).<ref name=Graham/><ref name=FE5/> The flower arrangement on the inflorescence may be either with ([[Biology:Pedicel (botany)|pedicellate]]) or without ([[Biology:Sessility (botany)|sessile]]) floral stalks.

Prior to opening, the flower buds are enveloped and protected in a thin dry papery or membranous ([[Biology:Glossary of botanical terms#S|scarious]]) spathe. The spathe consists of a singular [[Biology:Bract|bract]] that is ribbed, and which remains wrapped around the base of the open flower. As the bud grows, the spathe splits longitudinally.{{sfn|Sell|Murrell|1996|loc=[https://books.google.com/books?id=pKGlBap0FRYC&pg=PA285 Narcissus], p. 285}}{{sfn|Johnston|2007}} Bracteoles are small or absent.{{sfn|Straley|Utech|2003}}{{sfn|Sell|Murrell|1996|loc=[https://books.google.com/books?id=pKGlBap0FRYC&pg=PA285 Narcissus], p. 285}}<ref name=FE5/><ref name=Barrett/>

; Flowers :
The '''[[Biology:Flower|flower]]s''' of ''Narcissus'' are [[Biology:Hermaphrodite#Plants|hermaphroditic]] (bisexual),<ref name=Medrano/> have three parts (tripartite), and are sometimes fragrant (see Fragrances).{{sfn|Dobson|1997}} The flower symmetry is actinomorphic (radial) to slightly zygomorphic (bilateral) due to declinate-ascending [[Biology:Stamen|stamen]]s (curving downwards, then bent up at the tip). ''Narcissus'' flowers are characterised by their, usually conspicuous, corona (trumpet).

The three major floral parts (in all species except ''[[Biology:Narcissus cavanillesii|N. cavanillesii]]'' in which the corona is virtually absent - Table I: Section ''Tapeinanthus'') are;
* (i) the proximal floral tube (hypanthium),
* (ii) the surrounding free [[Biology:Tepal|tepal]]s, and
* (iii) the more distal corona (paraperigon, paraperigonium).

All three parts may be considered to be components of the [[Biology:Perianth|perianth]] (perigon, perigonium). The [[Biology:Perianth|perianth]] arises above the apex of the inferior [[Biology:Ovary (botany)|ovary]], its base forming the hypanthial floral tube.

The floral tube is formed by fusion of the basal segments of the tepals (proximally connate). Its shape is from an inverted cone ([[Obconic|obconic]]) to funnel-shaped (funneliform) or cylindrical, and is surmounted by the more distal corona. Floral tubes can range from long and narrow sections ''Apodanthi'' and ''Jonquilla'' to rudimentary (''N. cavanillesii'').{{sfn|Lloyd|Barrett|1995|loc=[https://books.google.com/books?id=HgFA7mFHp2QC&pg=PA343 Barrett S, Lloyd D. Stylar polymorphisms and the evolution of heterostyly in ''Narcissus'' (Amaryllidaceae)], p. 343}}

Surrounding the floral tube and corona and [[Biology:Glossary of botanical terms#reflexed|reflexed]] (bent back) from the rest of the perianth are the six spreading tepals or floral leaves, in two whorls which may be distally ascending, reflexed (folded back), or lanceolate. Like many monocotyledons, the perianth is homochlamydeous, which is undifferentiated into separate calyx (sepals) and corolla (petals), but rather has six tepals. The three outer tepal segments may be considered [[Biology:Sepal|sepal]]s, and the three inner segments [[Biology:Petal|petal]]s. The transition point between the floral tube and the corona is marked by the insertion of the free tepals on the fused perianth.{{sfn|Okubo|Sochacki |2012|p=[https://books.google.com/books?id=5B-ucdbgA3wC&pg=PA104 104]}}

The corona, or paracorolla, is variously described as bell-shaped (funneliform, trumpet), bowl-shaped (cupular, crateriform, cup-shaped) or disc-shaped with margins that are often frilled, and is free from the stamens. Rarely is the corona a simple callose (hardened, thickened) ring. The corona is formed during floral development as a tubular outgrowth from stamens which fuse into a tubular structure, the anthers becoming reduced. At its base, the fragrances which attract pollinators are formed. All species produce nectar at the top of the ovary.<ref name=Graham/> Coronal morphology varies from the tiny pigmented disk of ''[[Biology:Narcissus serotinus|N. serotinus]]'' (see Table I) or the rudimentary structure in ''[[Biology:Narcissus cavanillesii|N. cavanillesii]]'' to the elongated trumpets of section ''Pseudonarcissus'' (trumpet daffodils, Table I).{{sfn|Kubitzki|1998|loc=[https://books.google.com/books?id=FyPVYzL76sMC&pg=PA100 Narcissus], pp. 100–101}}<ref name=Graham/><ref name=FE5/>{{sfn|Okubo|Sochacki |2012|p=[https://books.google.com/books?id=5B-ucdbgA3wC&pg=PA104 104]}}

While the perianth may point forwards, in some species such as ''N. cyclamineus'' it is folded back (reflexed, see illustration, left), while in some other species such as ''[[Biology:Narcissus bulbocodium|N. bulbocodium]]'' (Table I), it is reduced to a few barely visible pointed segments with a prominent corona.

The colour of the perianth is white, yellow or bicoloured, with the exception of the night flowering ''[[Biology:Narcissus viridiflorus|N. viridiflorus]]'' which is green. In addition the corona of ''[[Biology:Narcissus poeticus|N. poeticus]]'' has a red crenulate margin (see Table I).{{sfn|Sell|Murrell|1996|loc=[https://books.google.com/books?id=pKGlBap0FRYC&pg=PA285 Narcissus. p. 285]}} Flower diameter varies from 12&nbsp;mm (''[[Biology:Narcissus bulbocodium|N. bulbocodium]]'') to over 125&nbsp;mm (''N. nobilis''=''[[Biology:Narcissus pseudonarcissus|N. pseudonarcissus]]'' subsp. ''nobilis'').{{sfn|Lloyd|Barrett|1995|loc=[https://books.google.com/books?id=HgFA7mFHp2QC&pg=PA343 Barrett S, Lloyd D. Stylar polymorphisms and the evolution of heterostyly in ''Narcissus'' (Amaryllidaceae)], p. 343}}

Flower orientation varies from pendent or deflexed (hanging down) as in ''N. triandrus'' (see illustration, left), through declinate-ascendant as in [[Biology:Narcissus pseudonarcissus|''N. alpestris'' = ''N. pseudonarcissus'' subsp. ''moschatus'']], horizontal (patent, spreading) such as ''[[Biology:Narcissus gaditanus|N. gaditanus]]'' or ''[[Biology:Narcissus poeticus|N. poeticus]]'', erect as in ''N. cavanillesii'', ''N. serotinus'' and ''[[Biology:Narcissus rupicola|N. rupicola]]'' (Table I), or intermediate between these positions (erecto-patent).{{sfn|Straley|Utech|2003}}{{sfn|Sell|Murrell|1996|loc=[https://books.google.com/books?id=pKGlBap0FRYC&pg=PA285 Narcissus. p. 285]}}<ref name=Graham/><ref name=FE5/><ref name=Barrett/><ref name=Mathew/>{{sfn|Lloyd|Barrett|1995|loc=[https://books.google.com/books?id=HgFA7mFHp2QC&pg=PA343 Barrett S, Lloyd D. Stylar polymorphisms and the evolution of heterostyly in ''Narcissus'' (Amaryllidaceae)], p. 343}}

The flowers of ''Narcissus'' demonstrate exceptional floral diversity and sexual [[Biology:Polymorphism|polymorphism]],<ref name=Barrett/> primarily by corona size and floral tube length, associated with [[Biology:Pollinator|pollinator]] groups (see for instance Figs. 1 and 2 in Graham and Barrett<ref name=Graham/>). Barrett and Harder (2005) describe three separate floral patterns;
* "Daffodil" form
* "Paperwhite" form
* "Triandrus" form.

The predominant patterns are the 'daffodil' and 'paperwhite' forms, while the "triandrus" form is less common. Each corresponds to a different group of pollinators (See Pollination).<ref name=Barrett/>

The "daffodil" form, which includes sections ''Pseudonarcissus'' and ''Bulbocodium'', has a relatively short, broad or highly funnelform tube (funnel-like), which grades into an elongated corona, which is large and funnelform, forming a broad, cylindrical or trumpet-shaped perianth. Section ''Pseudonarcissus'' consists of relatively large flowers with a corolla length of around 50 mm, generally solitary but rarely in inflorescences of 2–4 flowers. They have wide greenish floral tubes with funnel-shaped bright yellow coronas. The six tepals sometimes differ in colour from the corona and may be cream coloured to pale yellow.<ref name=Medrano/>

The "paperwhite" form, including sections ''Jonquilla'', ''Apodanthi'' and ''Narcissus'', has a relatively long, narrow tube and a short, shallow, flaring corona. The flower is horizontal and fragrant.

The "triandrus" form is seen in only two species, ''[[Biology:Narcissus albimarginatus|N. albimarginatus]]'' (a Moroccan endemic) and ''N. triandrus''. It combines features of both the "daffodil" and "paperwhite" forms, with a well-developed, long, narrow tube and an extended bell-shaped corona of almost equal length. The flowers are pendent.<ref name=Barrett/>

; Androecium :
There are six [[Biology:Stamen|stamen]]s in one to two rows ([[Biology:Whorl (botany)|whorls]]), with the filaments separate from the corona, attached at the throat or base of the tube (epipetalous), often of two separate lengths, straight or declinate-ascending (curving downwards, then upwards). The anthers are basifixed (attached at their base).{{sfn|Kubitzki|1998|loc=[https://books.google.com/books?id=FyPVYzL76sMC&pg=PA100 Narcissus], pp. 100–101}}{{sfn|Okubo|Sochacki |2012|p=[https://books.google.com/books?id=5B-ucdbgA3wC&pg=PA104 104]}}

; [[Biology:Gynoecium|Gynoecium]] :
The [[Biology:Ovary (botany)|ovary]] is inferior (below the floral parts) and [[Biology:Locule|trilocular]] (three chambered) and there is a pistil with a minutely three lobed [[Biology:Stigma (botany)|stigma]] and filiform (thread like) style, which is often exserted (extending beyond the tube).{{sfn|Kubitzki|1998|loc=[https://books.google.com/books?id=FyPVYzL76sMC&pg=PA100 Narcissus pp. 100–101]}}{{sfn|Okubo|Sochacki |2012|p=[https://books.google.com/books?id=5B-ucdbgA3wC&pg=PA104 104]}}

; Fruit :
The fruit consists of dehiscent loculicidal capsules (splitting between the locules) that are [[Ellipsoid|ellipsoid]] to [[Biology:Glossary of botanical terms#S|subglobose]] (almost spherical) in shape and are papery to leathery in texture.{{sfn|Straley|Utech|2003}}

; Seeds :
The fruit contains numerous subglobose '''[[Biology:Seed|seed]]s''' which are round and swollen with a hard coat, sometimes with an attached [[Biology:Elaiosome|elaiosome]]. The [[Biology:Seed#Seed coat|testa]] is black{{sfn|Kubitzki|1998|loc=[https://books.google.com/books?id=FyPVYzL76sMC&pg=PA100 Narcissus], pp. 100–101}} and the pericarp dry.<ref name=FE5/>

Most species have 12 ovules and 36 seeds, although some species such as ''N. bulbocodium'' have more, up to a maximum of 60. Seeds take five to six weeks to mature. The seeds of sections ''Jonquilla'' and ''Bulbocodium'' are wedge-shaped and matte black, while those of other sections are ovate and glossy black. A gust of wind or contact with a passing animal is sufficient to [[Earth:Seed dispersal|disperse]] the mature seeds.

===Chromosomes===
[[Biology:Chromosome|Chromosome]] numbers include 2n=14, 22, 26, with numerous aneuploid and polyploid derivatives. The basic chromosome number is 7, with the exception of ''[[Biology:Narcissus tazetta|N. tazetta]]'', ''[[Biology:Narcissus elegans|N. elegans]]'' and ''N. broussonetii'' in which it is 10 or 11; this subgenus (''Hermione'') was in fact characterised by this characteristic. Polyploid species include ''[[Biology:Narcissus papyraceus|N. papyraceus]]'' (4x=22) and ''[[Biology:Narcissus dubius|N. dubius]]'' (6x=50).{{sfn|Okubo|Sochacki |2012|p=[https://books.google.com/books?id=5B-ucdbgA3wC&pg=PA104 104]}}

===Phytochemistry===
====Alkaloids====
As with all Amarylidaceae genera, ''Narcissus'' contains unique [[Chemistry:Isoquinoline|isoquinoline]] [[Chemistry:Alkaloid|alkaloid]]s. The first alkaloid to be identified was [[Chemistry:Lycorine|lycorine]], from ''N. pseudonarcissus'' in 1877. These are considered a protective adaptation and are utilised in the classification of species. Nearly 100 alkaloids have been identified in the genus, about a third of all known Amaryllidaceae alkaloids, although not all species have been tested. Of the nine alkaloid [[Chemistry:Ring|ring]] types identified in the family, ''Narcissus'' species most commonly demonstrate the presence of alkaloids from within the Lycorine (lycorine, galanthine, pluviine) and [[Chemistry:Homolycorine|Homolycorine]] (homolycorine, lycorenine) groups. Hemanthamine, tazettine, [[Chemistry:Narciclasine|narciclasine]], montanine and [[Chemistry:Galantamine|galantamine]] alkaloids are also represented. The alkaloid profile of any plant varies with time, location, and developmental stage.<ref name=Bastida/> ''Narcissus'' also contain fructans and low molecular weight [[Chemistry:Glucomannan|glucomannan]] in the leaves and plant stems.

====Fragrances====
Fragrances are predominantly [[Chemistry:Monoterpene|monoterpene]] isoprenoids, with a small amount of benzenoids, although ''N. jonquilla'' has both equally represented. Another exception is ''[[Biology:Narcissus cuatrecasasii|N. cuatrecasasii]]'' which produces mainly fatty acid derivatives. The basic monoterpene precursor is [[Chemistry:Geranyl pyrophosphate|geranyl pyrophosphate]], and the commonest monoterpenes are [[Chemistry:Limonene|limonene]], [[Chemistry:Myrcene|myrcene]], and ''trans''-β-[[Chemistry:Ocimene|ocimene]]. Most benzenoids are non-methoxylated, while a few species contain methoxylated forms (ethers), ''e.g.'' ''[[Biology:Narcissus bujei|N. bujei]]''. Other ingredient include [[Chemistry:Indole|indole]], isopentenoids and very small amounts of sesquiterpenes. Fragrance patterns can be correlated with pollinators, and fall into three main groups (see Pollination).{{sfn|Dobson|1997}}

==Taxonomy==

=== History ===
{{Blockquote|text=''Genus valde intricatum et numerosissimis dubiis oppressum''<br/> A genus that is very complex and burdened with numerous uncertainties|sign=Schultes & Schultes fil.|source=''Syst. Veg.'' 1829<ref name=Schultes/>}}

==== Early ====
The genus ''Narcissus'' was well known to the [[History:Classical antiquity|ancient Greeks and Romans]]. In [[Social:Ancient Greek|Greek]] literature [[Biography:Theophrastus|Theophrastus]]{{sfn|Theophrastus|1916|p=[https://archive.org/stream/enquiryintoplant02theouoft#page/42/mode/2up 42]}} and Dioscorides<ref name=Dioscurides/> described ''νάρκισσος'', probably referring to ''[[Biology:Narcissus poeticus|N. poeticus]]'', although the exact species mentioned in classical literature cannot be accurately established. Pliny the Elder later introduced the [[Social:Latin|Latin]] form ''narcissus''.<ref name=PlinyLat/><ref name=Pliny/><ref name=PlinyLat2/><ref name=Pliny2/> These early writers were as much interested in the plant's possible medicinal properties as they were in its botanical features and their accounts remained influential until at least the [[Philosophy:Renaissance|Renaissance]] (see also Antiquity). Mediaeval and Renaissance writers include Albert Magnus and William Turner, but it remained to [[Biography:Carl Linnaeus|Linnaeus]] to formally describe and name ''Narcissus'' as a genus in his [[Biology:Species Plantarum|Species Plantarum]] (1753) at which time there were six known species.<ref name=LinSP/><ref name=Meerow/>

==== Modern ====
De Jussieu (1789) grouped ''Narcissus'' into a "family",<ref name=icn18.2/><ref name=Candolle2/> which he called Narcissi.<ref name=Jussieu/> This was renamed Amaryllideae by Jaume Saint-Hilaire in 1805,<ref name=JSH/> corresponding to the modern [[Biology:Amaryllidaceae|Amaryllidaceae]]. For a while, ''Narcissus'' was considered part of [[Biology:Liliaceae|Liliaceae]] (as in the illustration seen here of ''Narcissus candidissimus''),{{sfn|Redouté|De Candolle|1805–1808|loc=[https://www.biodiversitylibrary.org/item/10268#page/56/mode/1up vol. IV, p. 188]}}<ref name=Candollea/><ref name=Candolleb/> but then the Amaryllidaceae were split off from it.{{sfn|A. P. de Candolle|1813|p=219}}{{sfn|Brown|1810|loc=[https://www.biodiversitylibrary.org/item/21871#page/164/mode/1up Prodromus], p. 296}}
[[File:Narcissus candidissimus.jpg|thumb|''N. candidissimus'' by Pierre-Joseph Redouté, 1808{{sfn|Redouté|De Candolle|1805–1808|loc=[https://www.biodiversitylibrary.org/item/10268#page/56/mode/1up vol. IV, p. 188]}}]]

Various authors have adopted either narrow (e.g. Haworth,<ref name=Haworth/><ref name=BurbigeHaworth/> Salisbury<ref name=Salisbury/>) or wide (e.g.Herbert,<ref name=Herbert/> Spach<ref name=Spach/> ) interpretations of the genus.<ref name=RHSSegregate/> The narrow view treated many of the species as separate genera.{{sfn|Webb|1978}} Over time, the wider view prevailed with a major monograph on the genus being published by Baker (1875).<ref name=Baker/> One of the more controversial genera was ''Tapeinanthus'',<ref name=Cullen/>{{sfn|Webb|1978}} but today it is included in ''Narcissus''.<ref name=Mathew/>

The eventual position of ''Narcissus'' within the [[Biology:Amaryllidaceae|Amaryllidaceae]] family only became settled in this century with the advent of phylogenetic analysis and the [[Biology:Angiosperm Phylogeny Group|Angiosperm Phylogeny Group]] system.<ref name=Meerow/>{{sfn|Stevens|2015}} Within Amaryllidaceae the [[Biology:Genus|genus]] ''Narcissus'' belongs to the [[Biology:Narcisseae|Narcisseae]] tribe, one of 13 within the [[Biology:Amaryllidoideae|Amaryllidoideae]] subfamily.<ref name=Bastida/> It is one of two [[Biology:Sister group|sister]] clades corresponding to genera in the Narcisseae,<ref name=Gage/> being distinguished from ''[[Biology:Sternbergia|Sternbergia]]'' by the presence of a paraperigonium,{{sfn|Hanks|2002|loc=[https://books.google.com/books?id=4_kH_BffGDgC&pg=PA1 Hanks, "The biology of ''Narcissus''"], pp. 1–29}} and is [[Biology:Monophyletic|monophyletic]].<ref name=Graham/>

=== Subdivision ===
The infrageneric phylogeny of ''Narcissus'' still remains relatively unsettled,<ref name=Bastida/> the taxonomy having proved complex and difficult to resolve,<ref name=FE5/><ref name=Medrano/><ref name=Mathew/> due to the diversity of the wild species, the ease with which natural [[Biology:Hybrid|hybridization]] occurs, and extensive cultivation and breeding accompanied by escape and naturalisation.<ref name=Bastida/><ref name=Zonneveld/> Consequently, the number of accepted species has varied widely.<ref name=Zonneveld/>

De Candolle, in the first systematic taxonomy of ''Narcissus'', arranged the species into named groups, and those names have largely endured for the various subdivisions since and bear his name as their authority.<ref name=Candollea/><ref name=Candolleb/> The situation was confused by the inclusion of many unknown or garden varieties, and it was not until the work of Baker that the wild species were all grouped as sections under one genus, ''Narcissus''.<ref name=Baker/>

A common classification system has been that of Fernandes <ref name=Fernandes68/><ref name=Fernandes75/><ref name=Fernandes51/> based on cytology, as modified by Blanchard (1990)<ref name=Blanchard/><ref name=Levy/> and Mathew (2002).<ref name=Mathew/> Another is that of Meyer (1966).<ref name=Meyer/> Fernandes proposed two subgenera based on basal chromosome numbers, and then subdivided these into ten [[Biology:Section (botany)|sections]] as did Blanchard.<ref name=Levy/>

Other authors (e.g. Webb<ref name=FE5/>{{sfn|Webb|1978}}) prioritised morphology over genetics, abandoning subgenera, although Blanchard's system has been one of the most influential. While infrageneric groupings within ''Narcissus'' have been relatively constant, their status (genera, subgenera, sections, subsections, series, species) has not.<ref name=Mathew/><ref name=Bastida/> The most cited system is that of the Royal Horticultural Society (RHS) which simply lists ten sections. Three of these are monotypic (contain only one species), while two others contain only two species. Most species are placed in section ''Pseudonarcissus''.<ref name=RHSBC/><ref name=Santos-Gally/> Many of these subdivisions correspond roughly to the popular names for daffodil types, ''e.g.'' Trumpet Daffodils, Tazettas, Pheasant's Eyes, Hoop Petticoats, Jonquils.<ref name=Mathew/>

The most hierarchical system is that of Mathew, illustrated here -

==== Phylogenetics ====
The phylogenetic analysis of Graham and Barrett (2004) supported the infrageneric division of ''Narcissus'' into two clades corresponding to Fernandes' subgenera, but did not support monophyly of all sections.<ref name=Graham/> A later extended analysis by Rønsted ''et al.'' (2008) with additional taxa confirmed this pattern.<ref name=Ronsted2008/>

A large molecular analysis by Zonneveld (2008) sought to reduce some of the [[Biology:Paraphyly|paraphyly]] identified by Graham and Barrett. This led to a revision of the sectional structure.<ref name=Zonneveld/><ref name=Santos-Gally/><ref name=FCasas2008/>
While Graham and Barrett (2004)<ref name=Graham/> had determined that subgenus ''Hermione'' was monophyletic, Santos-Gally ''et al.'' (2011)<ref name=Santos-Gally/> did not. If two species excluded in the former study are removed from the analysis, the studies are in agreement, the species in question instead forming a clade with subgenus ''Narcissus''. Some so-called nothosections have been proposed, to accommodate natural ('ancient') hybrids (nothospecies).<ref name=FCasas2008/>

==== Species ====
{{Main|Biology:List of Narcissus species}}
[[File:Narcissi Encylopaedia Londinensis.jpg|thumb|''[[Biology:Narcissus hispanicus|N. major]]'', ''N. triandrus'' and ''N. jonquilla''. ''Encyclopaedia Londinensis'' 1819]]
Estimates of the number of species in ''Narcissus'' have varied widely, from anywhere between 16 and almost 160,<ref name=Zonneveld/><ref name=Blanchard/> even in the modern era. Linnaeus originally included six species in 1753, by 1784 there were fourteen{{sfn|Linné|1784|loc=[https://books.google.com/books?id=03gZAAAAYAAJ&q=narcissus&pg=PA316 p.316]}} by 1819 sixteen,{{sfn|Wilkes|1819}} and by 1831 Adrian Haworth had described 150 species.<ref name=Haworth/>

Much of the variation lies in the definition of [[Biology:Species|species]]. Thus, a very wide view of each species, such as Webb's<ref name=FE5/> results in few species, while a very narrow view such as that of Fernandes<ref name=Fernandes68/> results in a larger number.<ref name=Mathew/> Another factor is the status of [[Biology:Hybrid|hybrids]], with a distinction between "ancient hybrids" and "recent hybrids". The term "ancient hybrid" refers to hybrids found growing over a large area, and therefore now considered as separate species, while "recent hybrid" refers to solitary plants found amongst their parents, with a more restricted range.<ref name=Zonneveld/>

Fernandes (1951) originally accepted 22 species,<ref name=Fernandes51/> Webb (1980) 27.<ref name=FE5/> By 1968, Fernandes had 63 species,<ref name=Fernandes68/> Blanchard (1990) 65 species,<ref name=Blanchard/> and Erhardt (1993) 66.<ref name=Erhardt/> In 2006 the Royal Horticultural Society's (RHS) ''International Daffodil Register and Classified List'' <ref name=RHSBC/><ref name=RHSIRA/><ref name=RHSIRAS/> listed 87 species, while Zonneveld's genetic study (2008) resulted in only 36.<ref name=Zonneveld/> {{As of|2014|September}}, the [[Biology:World Checklist of Selected Plant Families|World Checklist of Selected Plant Families]] accepts 52 species, along with at least 60 hybrids,<ref name="WCSP_Narcissus"/> while the RHS has 81 accepted names in its October 2014 list.<ref name=RHSbotnames/>

=== Evolution ===
Within the [[Biology:Narcisseae|Narcisseae]], ''Narcissus'' (western Mediterranean) diverged from ''[[Biology:Sternbergia|Sternbergia]]'' ([[Earth:Eurasia|Eurasia]]) some time in the Late Oligocene to [[Earth:Early Miocene|Early Miocene]] eras, around 29.3–18.1 Ma. Later, the genus divided into the two subgenera (''Hermione'' and ''Narcissus'') between 27.4 and 16.1 Ma. The divisions between the sections of ''Hermione'' then took place during the Miocene period 19.9–7.8 Ma.<ref name=Santos-Gally/> ''Narcissus'' appears to have arisen in the area of the Iberian peninsula, southern France and northwestern Italy. Subgenus ''Hermione'' in turn arose in the southwestern Mediterranean and Northwest Africa.<ref name=Santos-Gally/>

===Names and etymology===
====Narcissus====
[[File:Clusius250.jpg|thumb|''N. juncifolius'', Carolus Clusius ''Rariorum stirpium'' 1576]]
[[File:L'Obel Icones Stirpium 112.jpg|thumb|''N. poeticus'', Matthias de l'Obel ''Icones stirpium'' 1591]]

The derivation of the Latin ''{{lang|la|narcissus}}''<ref>{{L&S|narcissus1|narcissus|ref}}</ref> is from Greek {{lang|grc|νάρκισσος}} ''narkissos''.<ref name="LSJ">{{LSJ|na/rkissos|νάρκισσος|ref}}.</ref><ref name="OEtymD">{{OEtymD|narcissus}}</ref> According to [[Philosophy:Plutarch|Plutarch]] ''narkissos'' has been connected because of the plant's narcotic properties, with ''narkē'' "numbness";<ref name="LSJ"/><ref>{{LSJ|na/rkeh|νάρκη|shortref}}.</ref> it may also be connected with hell.<ref name="Prior" /> On the other hand, its etymology is considered to be clearly Pre-Greek by Beekes.<ref>{{cite book|last=Beekes|first=Robert|title=Etymological Dictionary of Greek|publisher=Brill|others=With the assistance of Lucien van Beek.|year=2010|isbn=9789004174184|volume=2|place=Leiden, Boston|page=997|chapter=s.v. {{lang|grc|νάρκισσος}}|orig-year=2009}}</ref>

It is frequently linked to the myth of [[Philosophy:Narcissus (mythology)|Narcissus]], who became so obsessed with his own reflection in water that he drowned and the narcissus plant sprang from where he died. There is no evidence for the flower being named after Narcissus. ''[[Biology:Narcissus poeticus|Narcissus poeticus]]'', which grows in Greece, has a fragrance that has been described as intoxicating.<ref name="SOED" /> Pliny wrote that the plant was named for its fragrance ({{lang|grc|ναρκάω}} ''narkao'', "I grow numb" ), rather than Narcissus.<ref name="Bastida" /><ref name=PlinyLat/><ref name="Dweck" /><ref name="Groom1997" /><ref>{{LSJ|narka/w|ναρκάω|shortref}}.</ref> Furthermore, there were accounts of narcissi growing long before the story of Narcissus appeared (see Greek culture).<ref name="Prior" /><ref name="Pausanias" /><ref group="Note">Prior here refers to the poet ''Pamphilus'', but it is likely he meant ''Pamphos''.</ref> It has also been suggested that narcissi bending over streams represent the youth admiring his reflection.<ref name="Gardener" /> Linnaeus used the Latin name "narcissus" for the plant but was preceded by others such as Matthias de l'Obel (1591)<ref name="Obel" /> and Clusius (1576).{{sfn|Clusius|1576|loc=[https://www.biodiversitylibrary.org/item/30856#page/247/mode/1up De Narcisso, ii], pp. 245-25]}} The name Narcissus was not uncommon for men in Roman times.

The plural form of the common name "narcissus" has been the cause of some confusion. Dictionaries list "narcissi", "narcissuses" and "narcissus".<ref name="SOED" /><ref name="Cambridge" /><ref name="Webster" /> However, texts on usage such as Garner<ref name="Garner" /> and Fowler<ref name="Fowler" /> state that "narcissi" is the preferred form. The common name narcissus should not be capitalised.

====Daffodil====
The name "daffodil" is derived from "affodell", a variant of ''[[Biology:Asphodelus|asphodel]]''.<ref>{{OEtymD|daffodil}}</ref> The narcissus was frequently referred to as the asphodel<ref name=Dweck/> (see Antiquity). Asphodel in turn appears to come from the Greek "asphodelos" ({{lang-grc-gre|ἀσφόδελος}}).<ref name=Dweck/><ref>{{cite book|title=Oxford Dictionary of English|date=2010|edition=3rd}}</ref><ref>{{LSJ|a)sfo/delos|ἀσφόδελος|shortref}}.</ref><ref>{{OEtymD|asphodel}}</ref> The reason for the introduction of the initial "d" is not known.<ref name=Reece/> From at least the 16th century, "daffadown dilly" and "daffydowndilly" have appeared as alternative names.<ref name=SOED /> Other names include "Lent lily".<ref name="Hereford" /><ref name="Oxford" />

==== In other languages ====
The [[Social:Hokkien|Hokkien]] name for ''Narcissus'', ''chúi-sian'', can be literally translated as "water fairy", where ''chúi'' ({{linktext|水|lang=zh}}) refers to water and ''sian'' ({{linktext|仙|lang=zh}}) refers to immortals. It is the official provincial flower of Fujian.<ref>{{Cite web |title=福建省省花/省树/省石-传统文化-炎黄风俗网 |url=http://www.fengsuwang.com/minjian/fujianshenghuashengshushengshi.asp |access-date=2023-05-21 |website=www.fengsuwang.com}}</ref>

== Distribution and habitat ==
=== Distribution ===
Although the family [[Biology:Amaryllidaceae|Amaryllidaceae]] are predominantly tropical or subtropical as a whole, ''Narcissus'' occurs primarily in Mediterranean region, with a centre of diversity in the [[Place:Iberian Peninsula|Iberian Peninsula]] ({{wipe|Spain}} and Portugal).<ref name=Mathew/> A few species extend the range into southern France, Italy, the [[Place:Balkans|Balkans]] (''N. poeticus'', ''N. serotinus'', ''N. tazetta''), and the [[Place:Eastern Mediterranean|Eastern Mediterranean]] (''N. serotinus'')<ref name=Mathew/>{{sfn|Hanks|2002|loc=[https://books.google.com/books?id=4_kH_BffGDgC&pg=PA1 Hanks, "The biology of ''Narcissus''"], pp. 1–29}} including [[Place:Israel|Israel]] (''N. tazetta'').<ref name=Graham/><ref name=Bastida/> The occurrence of ''N. tazetta'' in western and central [[Earth:Asia|Asia]] as well as [[Place:East Asia|East Asia]] are considered [[Earth:Introduced species|introductions]], albeit ancient{{sfn|Hanks|2002|loc=[https://books.google.com/books?id=4_kH_BffGDgC&pg=PA1 Hanks, "The biology of ''Narcissus''"], pp. 1–29}} (see Eastern cultures). While the exact northern limit of the natural range is unknown, the occurrences of wild ''N. pseudonarcissus'' in Great Britain, middle and northern Europe are similarly considered ancient introductions.<ref name=Mathew/>{{sfn|Aedo|2010}}{{sfn|eMonocot|2014}}

While the Amaryllidaceae are not native to North America, ''Narcissus'' grows well in USDA [[Hardiness zone|hardiness zone]]s 3B through 10, which encompass most of the United States and Canada.<ref>{{Cite web|url=https://edis.ifas.ufl.edu/fp423|title=University of Florida IFAS Extension Edis|date=2015-08-17|website=University of Florida IFAS Extension Edis|publisher=University of Florida|access-date=18 April 2016|archive-url=https://web.archive.org/web/20160320055317/http://edis.ifas.ufl.edu/fp423|archive-date=20 March 2016|url-status=live}}</ref>

''[[Biology:Narcissus elegans|N. elegans]]'' occurs on the North West African Coast (Morocco and [[Place:Libya|Libya]]), as well as the coastline of [[Place:Corsica|Corsica]], Sardinia and Italy, and ''[[Biology:Narcissus bulbocodium|N. bulbocodium]]'' between [[Place:Tangier|Tangier]] and [[Place:Algiers|Algiers]] and Tangier to Marrakech, but also on the Iberian Peninsula. ''[[Biology:Narcissus serotinus|N. serotinus]]'' is found along the entire Mediterranean coast. ''[[Biology:Narcissus tazetta|N. tazetta]]'' occurs as far east as [[Religion:Iran|Iran]] and [[Place:Kashmir|Kashmir]]. Since this is one of the oldest species found in cultivation, it is likely to have been introduced into Kashmir. ''[[Biology:Narcissus poeticus|N. poeticus]]'' and ''[[Biology:Narcissus pseudonarcissus|N. pseudonarcissus]]'' have the largest distribution ranges. ''N. poeticus'' ranges from the Pyrenees along the Romanian Carpathians to the Black Sea and along the Dalmatian coast to Greece. ''N. pseudonarcissus'' ranges from the Iberian Peninsula, via the Vosges Mountains to northern {{wipe|France}} and Belgium, and the {{wipe|United Kingdom}} where there are still wild stocks in Southern Scotland. The only occurrence in Luxembourg is located near Lellingen, in the municipality of Kiischpelt. In {{wipe|Germany}} it is found mainly in the nature reserve at Perlenbach-Fuhrtsbachtal and the Eifel National Park, where in the spring at Monschau the meadows are teeming with yellow blooms.<ref name="PERLENBACH" /> One of the most easterly occurrences can be found at Misselberg near Nassau on the Lahn. 
[[File:Gacko Narcissus poeticus.jpg|thumb|''N. poeticus'' growing in Međulići, near Gacko, Bosnia and Herzegovina]]
However, unlike the above examples, most species have very restricted endemic ranges<ref name=Santos-Gally/>{{sfn|Medrano|2008}} which may overlap resulting in natural hybrids.<ref name=Zonneveld/> For instance in the vicinity of the Portuguese city of Porto where both ''N. pseudonarcissus'' and ''N. triandrus'' occur there are found various intersections of the two species while in a small area along part of the Portuguese Mondego river are found intersectional hybrids between ''[[Biology:Narcissus scaberulus|N. scaberulus]]'' and ''N. triandrus''.

The [[Earth:Biogeography|biogeography]] demonstrates a phylogenetic association, for instance subgenus ''Hermione'' having a lowland distribution, but subgenus ''Narcissus'' section ''Apodanthi'' being montane and restricted to Morocco, Spain and Portugal. The remaining sections within subgenus ''Narcissus'' include both lowland and mountain habitats.<ref name=Santos-Gally/> Section ''Pseudonarcissus'', although widely naturalised, is endemic to the Baetic Ranges of the southeastern Iberian peninsula.<ref name=Medrano/>

=== Habitats ===
Their native habitats are very varied, with different elevations, [[Holdridge life zones|bioclimatic areas]] and substrates,<ref name=Santos-Gally/> being found predominantly in open spaces ranging from low [[Earth:Marsh|marsh]]es to rocky hillsides and montane [[Earth:Pasture|pasture]]s, and including [[Earth:Grassland|grassland]], scrub, [[Biology:Woodland|woods]], [[Earth:Bank (geography)|river banks]] and [[Earth:Fracture (geology)|rocky crevices]].<ref name=Graham/><ref name=Bastida/> Although requirements vary, overall there is a preference for [[Biology:Soil pH#Sources of acidity|acidic]] soils, although some species will grow on [[Earth:Limestone|limestone]]. ''[[Biology:Narcissus scaberulus|Narcissus scaberulus]]'' will grow on [[Chemistry:Granite|granite]] soils where it is moist in the growing season but dry in the summer, while ''[[Biology:Narcissus dubius|Narcissus dubius]]'' thrives best in regions with hot and dry summers.

The ''Pseudonarcissus'' group in their natural habitat prefers humid situations such as stream margins, springs, wet pastures, clearings of forests or shrublands with humid soils, and moist hillsides. These habitats tend to be discontinuous in the Mediterranean mountains, producing discrete isolated populations.<ref name=Medrano/> In {{wipe|Germany}}, which has relatively little limestone, ''[[Biology:Narcissus pseudonarcissus|Narcissus pseudonarcissus]]'' grows in small groups on open mountain meadows or in mixed forests of [[Biology:Fir|fir]], [[Biology:Beech|beech]], [[Biology:Oak|oak]], [[Biology:Alder|alder]], [[Biology:Fraxinus|ash]] and [[Biology:Birch|birch]] trees with well-drained soil.

''Narcissus'' are long-lived perennial geophytes with winter-growing and summer-dormant bulbs<ref name=Medrano/> that are mainly synanthous (leaves and flowers appearing at the same time).{{sfn|Hanks|2002|loc=[https://books.google.com/books?id=4_kH_BffGDgC&pg=PA1 Hanks, "The biology of ''Narcissus''"], pp. 1–29}} While most species flower in late winter to spring, five species are autumn flowering (''[[Biology:Narcissus broussonetii|N. broussonetii]]'', ''[[Biology:Narcissus cavanillesii|N. cavanillesii]]'', ''[[Biology:Narcissus elegans|N. elegans]]'', ''[[Biology:Narcissus serotinus|N. serotinus]]'', ''[[Biology:Narcissus viridiflorus|N. viridiflorus]]'').<ref name=Graham/> By contrast, these species are hysteranthous (leaves appear after flowering).{{sfn|Hanks|2002|loc=[https://books.google.com/books?id=4_kH_BffGDgC&pg=PA1 Hanks, "The biology of ''Narcissus''"], pp. 1–29}}

Flower longevity varies by species and conditions, ranging from 5–20 days.{{sfn|Lloyd|Barrett|1995|loc=[https://books.google.com/books?id=HgFA7mFHp2QC&pg=PA344 Barrett S, Lloyd D. Stylar polymorphisms and the evolution of heterostyly in ''Narcissus'' (Amaryllidaceae)], p. 344}} After flowering leaf and root [[Biology:Senescence|senescence]] sets in, and the plant appears to be 'dormant' until the next spring, conserving moisture. However, the dormant period is also one of considerable activity within the bulb primordia. It is also a period during which the plant bulb may be susceptible to predators {{See below|{{section link||Pests and diseases}}, below}}. Like many bulb plants from temperate regions, a period of exposure to cold is necessary before spring growth can begin. This protects the plant from growth during winter when intense cold may damage it. Warmer spring temperatures then initiate growth from the bulb. Early spring growth confers a number of advantages, including relative lack of competition for pollinators, and lack of [[Biology:Deciduous|deciduous]] shading. {{sfn|Hanks|2002|loc=[https://books.google.com/books?id=4_kH_BffGDgC&pg=PA1 Hanks, "The biology of ''Narcissus''"], pp. 1–29}} The exception to requiring cold temperatures to initiate flowering is ''[[Biology:Narcissus tazetta|N. tazetta]]''.{{sfn|Okubo|Sochacki |2012|p=[https://books.google.com/books?id=5B-ucdbgA3wC&pg=PA104 104]}}

Plants may spread clonally through the production of daughter bulbs and division, producing clumps.<ref name=Medrano/> Narcissus species [[Biology:Hybrid|hybridise]] readily, although the fertility of the offspring will depend on the parental relationship.<ref name=Bastida/>

=== Pollination ===
The flowers are insect-pollinated, the major pollinators being bees, butterflies, flies, and hawkmoths, while the highly scented night-flowering ''[[Biology:Narcissus viridiflorus|N. viridiflorus]]'' is pollinated by crepuscular moths. Pollination mechanisms fall into three groups corresponding to floral morphology (see Description - Flowers).{{sfn|Lloyd|Barrett|1995|loc=[https://books.google.com/books?id=HgFA7mFHp2QC&pg=PA344 Barrett S, Lloyd D. Stylar polymorphisms and the evolution of heterostyly in ''Narcissus'' (Amaryllidaceae)], p. 344}}

# 'Daffodil' form. Pollinated by bees seeking [[Biology:Pollen|pollen]] from anthers within the corona. The broad perianth allows bees (''[[Biology:Bombus|Bombus]]'', ''[[Biology:Anthophora|Anthophora]]'', ''[[Biology:Andrena|Andrena]]'') to completely enter the flower in their search for nectar and/or pollen. In this type, the stigma lies in the mouth of the corona, extending beyond the six anthers, whose single [[Biology:Whorl (botany)|whorl]] lies well within the corona. The bees come into contact with the stigma before their legs, thorax and abdomen contact the anthers, and this approach herkogamy causes cross pollination.
# 'Paperwhite' form. These are adapted to long-tongued [[Biology:Lepidoptera|Lepidoptera]], particularly sphingid moths such as ''[[Biology:Macroglossum|Macroglossum]]'', [[Biology:Pieridae|Pieridae]] and [[Biology:Nymphalidae|Nymphalidae]], but also some long-tongued bees, and flies, all of which are primarily seeking [[Biology:Nectar|nectar]]. The narrow tube admits only the insect's [[Biology:Proboscis|proboscis]], while the short corona serves as a funnel guiding the tip of the proboscis into the mouth of the perianth tube. The stigma is placed either in the mouth of the tube, just above two whorls of three anthers, or hidden well below the anthers. The pollinators then carry pollen on their probosci or faces. The long-tongued bees cannot reach the nectar at the tube base and so collect just pollen. 
# 'Triandrus' form. Pollinated by long-tongued solitary bees (''[[Biology:Anthophora|Anthophora]]'', ''[[Biology:Bombus|Bombus]]''), which forage for both pollen and nectar. The large corona allows the bees to crawl into the perianth but then the narrow tube prevents further progress, causing them to probe deeply for nectar. The pendant flowers prevent pollination by Lepidoptera. In ''N. albimarginatus'' there may be either a long stigma with short and mid-length anthers or a short stigma and long anthers ([[Biology:Polymorphism|dimorphism]]). In ''N. triandrus'' there are three patterns of sexual organs (trimophism) but all have long upper anthers but vary in stigma position and the length of the lower anthers.<ref name=Graham/><ref name=Barrett/>

[[Biology:Allogamy|Allogamy]] ([[Biology:Outcrossing|outcrossing]]) on the whole is enforced through a late-acting ([[Biology:Ovary (botany)|ovarian]]) [[Biology:Self-incompatibility|self-incompatibility]] system, but some species such as ''[[Biology:Narcissus dubius|N. dubius]]'' and ''[[Biology:Narcissus longispathus|N. longispathus]]'' are self-compatible producing mixtures of selfed and outcrossed seeds.{{sfn|Dobson|1997}}<ref name=Barrett/>

=== Pests and diseases ===
Diseases of ''Narcissus'' are of concern because of the economic consequences of losses in commercial cultivation. Pests include viruses, bacteria, and fungi as well as arthropods and gastropods. For control of pests, see Commercial uses.

; Viruses :
[[Biology:Aphid|Aphid]]s such as ''[[Biology:Macrosiphum euphorbiae|Macrosiphum euphorbiae]]'' can transmit [[Biology:Virus|viral]] diseases which affect the colour and shape of the leaves, as can nematodes.{{sfn|Zuckerman|Rohde|1981|loc=[https://books.google.com/books?id=pU9Mz--9wwoC&pg=PA286 Longidorus transmitted viruses], p. 286}} Up to twenty-five viruses have been described as being able to infect narcissi.{{sfn|PNW|2014}}{{sfn|Berniak|Komorowska|Sochacki|2013}}{{sfn|Asjes|1996}} These include the ''Narcissus common latent virus'' (NCLV, ''Narcissus mottling-associated virus''{{sfn|Adams|2013|loc=[http://www.dpvweb.net/notes/search.php ''Find Viruses'': Narcissus]}}),<ref group="Note">This ''[[Biology:Carlavirus|Carlavirus]]'' should not be confused with the similarly named'' Narcissus latent virus'' which is a ''[[Biology:Macluravirus|Macluravirus]]''.</ref> ''[[Biology:Narcissus latent virus|Narcissus latent virus]]'' (NLV, ''Narcissus mild mottle virus''{{sfn|Adams|2013|loc=[http://www.dpvweb.net/notes/search.php ''Find Viruses'': Narcissus]}}) which causes green mottling near leaf tips,{{sfn|Smith|1988|loc=[https://books.google.com/books?id=3gbPsC7i1IIC&pg=PA3 Viruses], p. 3}}<ref>{{cite web |url=http://www.dpvweb.net/dpv/showdpv.php?dpvno=170 |author1=A.

Less host specific viruses include ''Raspberry ringspot virus'', ''Nerine latent virus'' (NeLV) =''Narcissus symptomless virus'',{{sfn|Chen|2006}} ''Arabis mosaic virus'' (ArMV),{{sfn|Iwaki|1974}} ''[[Biology:Fabavirus|Broad Bean Wilt Viruses]]'' (BBWV){{sfn|Iwaki|1972}} ''[[Biology:Cucumber mosaic virus|Cucumber mosaic virus]]'' (CMV), ''[[Biology:Tomato black ring virus|Tomato black ring virus]]'' (TBRV), ''[[Biology:Tomato ringspot virus|Tomato ringspot virus]]'' (TomRSV) and ''[[Biology:Tobacco rattle virus|Tobacco rattle virus]]'' (TRV).{{sfn|Iwaki|1972}}{{sfn|Okubo|Sochacki |2012|p=[https://books.google.com/books?id=5B-ucdbgA3wC&pg=PA108 108]}}

Of these viruses the most serious and prevalent are NDV, NYSV and NWSV.{{sfn|Okubo|Sochacki |2012|p=[https://books.google.com/books?id=5B-ucdbgA3wC&pg=PA108 108]}}{{sfn|Berniak|Komorowska|Sochacki|2013}} NDV is associated with chlorotic leaf striping in ''[[Biology:Narcissus tazetta|N. tazetta]]''.{{sfn|Chen|2007}} Infection with NYSV produces light or grayish-green, or yellow stripes or mottles on the upper two-thirds of the leaf, which may be roughened or twisted. The flowers which may be smaller than usual may also be streaked or blotched. NWSV produces greenish-purple streaking on the leaves and stem turning white to yellow, and premature senescence reducing bulb size and yield.{{sfn|PNW|2014}} These viruses are primarily diseases of commercial nurseries. The growth inhibition caused by viral infection can cause substantial economic damage.{{sfn|Daffodil Society|2014|loc=[http://thedaffodilsociety.com/wordpress/a-guide-to-dafodils/pests-diseases/ Pests & Diseases]}}{{sfn|UCIPM|2009}}{{sfn|RHS|2014|loc=[https://www.rhs.org.uk/advice/profile?PID=149 Daffodil viruses]}}

; [[Biology:Bacteria|Bacteria]] :
Bacterial disease is uncommon in ''Narcissus'' but includes ''[[Biology:Pseudomonas|Pseudomonas]]'' (bacterial streak) and ''[[Biology:Pectobacterium carotovorum|Pectobacterium carotovorum]]'' sp. ''carotovorum'' (bacterial soft rot).{{sfn|Okubo|Sochacki |2012|p=[https://books.google.com/books?id=5B-ucdbgA3wC&pg=PA108 108]}}

; [[Biology:Fungi|Fungi]] :
More problematic for non-commercial plants is the [[Biology:Fungus|fungus]], [[Biology:Fusarium oxysporum|''Fusarium oxysporum'' f. sp. ''narcissi'']], which causes basal rot (rotting of the bulbs and yellowing of the leaves). This is the most serious disease of ''Narcissus''. Since the fungus can remain in the soil for many years it is necessary to remove infected plants immediately, and to avoid planting further narcissi at that spot for a further five years. Not all species and cultivars are equally susceptible. Relatively resistant forms include ''N. triandrus'', ''[[Biology:Narcissus tazetta|N. tazetta]]'' and ''N. jonquilla''.{{sfn|RHS|2014|loc=[https://www.rhs.org.uk/advice/profile?pid=222 Narcissus basal rot]}}{{sfn|Okubo|Sochacki |2012|p=[https://books.google.com/books?id=5B-ucdbgA3wC&pg=PA108 108]}}{{sfn|Hanks|1996}}{{sfn|Hanks|Carder|2003}}

Another fungus which attacks the bulbs, causing narcissus smoulder, is ''[[Biology:Botrytis narcissicola|Botrytis narcissicola]]'' (''Sclerotinia narcissicola'') and other species of ''[[Biology:Botryotinia|Botrytis]]'', including ''[[Biology:Botrytis cinerea|Botrytis cinerea]]'',{{sfn|O'Neill|Mansfield|1980}}{{sfn|Hong|2007}} particularly if improperly stored. Copper sulfate is used to combat the disease, and infected bulbs are burned. Blue mould rot of bulbs may be caused by infection with species of ''[[Biology:Penicillium|Penicillium]]'', if they have become damaged either through mechanical injury or infestation by mites (see below).{{sfn|Pirone|1978|loc=[https://archive.org/details/diseasespestsofo0000piro/page/366 Narcissus], p. 366}} Species of [[Biology:Rhizopus|Rhizopus]] (''e.g.'' ''[[Biology:Rhizopus stolonifer|Rhizopus stolonifer]]'', ''Rhizopus nigricans'') cause bulb soft rot{{sfn|UCIPM|2009}}{{sfn|Horst|2013|loc=[https://link.springer.com/chapter/10.1007/978-94-007-6049-3_17 Narcissus], pp. 95–96}} and ''[[Biology:Sclerotinia bulborum|Sclerotinia bulborum]]'', black slime disease.{{sfn|Boerema|1989}} A combination of both ''[[Biology:Peyronellaea curtisii|Peyronellaea curtisii]]'' (''Stagonosporopsis curtisii'') and ''Botrytis narcissicola'' causes neck rot in the bulbs.{{sfn|Okubo|Sochacki |2012|p=[https://books.google.com/books?id=5B-ucdbgA3wC&pg=PA108 108]}}

Fungi affecting the roots include ''[[Biology:Nectria radicicola|Nectria radicicola]]'' (''Cylindrocarpon destructans''), a cause of root rot{{sfn|Boerema|1989}} and ''[[Biology:Rosellinia necatrix|Rosellinia necatrix]]'' causing white root rot,{{sfn|Mantell|1973}} while others affect root and bulb, such as ''[[Biology:Aspergillus niger|Aspergillus niger]]'' (black mold), and species of ''[[Biology:Trichoderma|Trichoderma]]'', including ''[[Biology:Trichoderma viride|T. viride]]'' and ''[[Biology:Trichoderma harzianum|T. harzianum]]'' (=''T. narcissi'') responsible for green mold.{{sfn|Horst|2013|loc=[https://link.springer.com/chapter/10.1007/978-94-007-6049-3_17 Narcissus], pp. 95–96}}

Other fungi affect the remainder of the plant. Another ''Botrytis'' fungus, ''Botrytis polyblastis'' (''Sclerotinia polyblastis'') causes brown spots on the flower buds and stems (narcissus fire), especially in damp weather and is a threat to the cut flower industry.{{sfn|Moore|1959|loc=[https://books.google.com/books?id=I_M8AAAAIAAJ&pg=PA343 ''Sclerotinia polyblastis'' p.343]}}{{sfn|Elad|2007}} ''[[Biology:Ramularia vallisumbrosae|Ramularia vallisumbrosae]]'' is a leaf spot fungus found in warmer climates, causing narcissus white mould disease.<ref name=Gregory/> ''Peyronellaea curtisii'', the Narcissus leaf scorch, also affects the leaves{{sfn|Daffodil Society|2014|loc=[http://thedaffodilsociety.com/wordpress/a-guide-to-dafodils/pests-diseases/ Pests & Diseases]}}{{sfn|UCIPM|2009}}<ref name="vanLeeuwen" /><ref name="McCain" />{{sfn|RHS|2014|loc=[https://www.rhs.org.uk/advice/profile?PID=735 Narcissus leaf scorch]}} as does its synanamorph, ''Phoma narcissi'' (leaf tip blight).{{sfn|Crous|2011}}{{sfn|Okubo|Sochacki |2012|p=[https://books.google.com/books?id=5B-ucdbgA3wC&pg=PA108 108]}} ''[[Biology:Aecidium narcissi|Aecidium narcissi]]'' causes [[Biology:Rust (fungus)|rust]] lesions on leaves and stems.{{sfn|Boerema|1989}}

; Animals :
Arthropods that are ''Narcissus'' pests include insects such as three species of [[Biology:Fly|fly]] that have larvae that attack the plants, the narcissus bulb fly ''[[Biology:Merodon equestris|Merodon equestris]]'', and two species of hoverflies, the lesser bulb flies ''[[Biology:Eumerus tuberculatus|Eumerus tuberculatus]]''<ref name="Creager" /> and ''[[Biology:Eumerus strigatus|Eumerus strigatus]]''. The flies lay their eggs at the end of June in the ground around the narcissi, a single female fly being able to lay up to fifty eggs. The hatching [[Biology:Larva|larva]]e then burrow through the soil towards the bulbs and consume their interiors. They then overwinter in the empty bulb shell, emerging in April to [[Biology:Pupa|pupa]]te in the soil, from which the adult fly emerges in May.{{sfn|Daffodil Society|2014|loc=[http://thedaffodilsociety.com/wordpress/a-guide-to-dafodils/pests-diseases/ Pests & Diseases]}}{{sfn|RHS|2014|loc=[https://www.rhs.org.uk/advice/profile?PID=657 Narcissus bulb fly]}} The larvae of some moths such as ''Korscheltellus lupulina'' (the common swift moth) attack ''Narcissus'' bulbs.{{sfn|MAFF|1970}}{{sfn|Daffodil Society|2014|loc=[http://thedaffodilsociety.com/wordpress/a-guide-to-dafodils/pests-diseases/ Pests & Diseases]}}

Of all the flowering plants, the bulbous have been the most popular for cultivation.{{sfn|Krelage|1890}} Of these, narcissi are one of the most important spring flowering bulb plants in the world.{{sfn|Okubo|Sochacki |2012|p=[https://books.google.com/books?id=5B-ucdbgA3wC&pg=PA103 103]}}{{sfn|Kubitzki|1998|loc=[https://books.google.com/books?id=FyPVYzL76sMC&pg=PA100 Narcissus], pp. 100–101}} [[Biology:Indigenous (ecology)|Indigenous]] in Europe, the wild populations of the parent species had been known since [[History:Classical antiquity|antiquity]]. Narcissi have been cultivated from at least as early as the sixteenth century in the Netherlands, when large numbers of bulbs where imported from the field, particularly ''[[Biology:Narcissus hispanicus|Narcissus hispanicus]]'', which soon became nearly extinct in its native habitat of France and Spain, though still found in the southern part of that country.<ref name=Zonneveld11/> The only large-scale production at that time related to the double narcissus "Van Sion" and cultivars of ''[[Biology:Narcissus tazetta|N. tazetta]]'' imported in 1557.{{sfn|Doorenbos|1954}}

Although not achieving the sensationalism of tulips, daffodils and narcissi have been much celebrated in art and literature {{See below|{{section link||Art}}, below}}. The largest demand for narcissi bulbs were large trumpet daffodils, ''N. poeticus'' and ''N. bulbocodium'', and Istanbul became important in the shipping of bulbs to western Europe. By the early [[History:Baroque|baroque]] period both tulips and narcissi were an important component of the spring garden. By 1739 a Dutch nursery catalogue listed 50 different varieties. In 1757 Hill gave an account of the history and cultivation of the daffodil in his edited version of the works of Thomas Hale, writing "The garden does not afford, in its Kind, a prettier plant than this; nor do we know one that has been so early, or so honorably mention'd by all Kinds of Writers" (see illustration).{{sfn|Hale|1757|loc=[https://www.biodiversitylibrary.org/item/131789#page/585/mode/1up pp. 495–496]}} Interest grew further when varieties that could be grown indoors became available, primarily the bunch flowered (multiple flower heads) ''N. tazetta'' (Polyanthus Narcissus).{{sfn|Krelage|1890}} However interest varied by country. Maddock (1792) does not include narcissi in his list of the eight most important cultivated flowering plants in England,{{sfn|Maddock|1792}} whereas in the Netherlands van Kampen (1760) stated that ''N. tazetta'' (''Narcisse à bouquet'') is the fifth most important – "''Le Narcisse à bouquet est la premiere fleur, après les Jacinthes, les Tulipes les Renoncules, et les Anemones, (dont nous avons déja parlé,) qui merite nôtre attention''".{{sfn|van Kampen et fils|1760|loc=[https://books.google.com/books?id=-3ZYAAAAcAAJ&pg=PA96 p. 96]}}{{sfn|van Kampen & Son|1764|loc=[https://books.google.com/books?id=DIYmAQAAMAAJ&pg=PA80 p. 80]}} Similarly Philip Miller, in his ''Gardeners Dictionary'' (1731–1768) refers to cultivation in Holland, Flanders and France, but not England,{{sfn|Miller|1735|loc=[https://www.biodiversitylibrary.org/item/71189#page/177/mode/1up vol. ii Narcissus]}} because it was too difficult, a similar observation was made by Sir James Justice at this time.{{sfn|Justice|1771|loc=[https://www.biodiversitylibrary.org/item/69306#page/366/mode/1up The Gardiner's new Director p. 304]}} However, for most species of ''Narcissus'' Lauremberg's dictum ''Magna cura non indigent Narcissi'' was much cited.{{sfn|Ellacombe|1884|loc=[https://archive.org/details/plantloregarden01ellagoog/page/n94 <!-- pg=76 --> Daffodils], p. 76}}

Narcissi became an important horticultural crop in Western Europe in the latter part of the nineteenth century, beginning in England between 1835 and 1855 and the end of the century in the Netherlands.{{sfn|Okubo|Sochacki |2012|p=[https://books.google.com/books?id=5B-ucdbgA3wC&pg=PA104 104]}} By the beginning of the twentieth century 50&nbsp;million bulbs of ''N. Tazetta'' "Paperwhite" were being exported annually from the Netherlands to the United States. With the production of triploids such as "Golden Spur", in the late nineteenth century, and in the beginning of the twentieth century, tetraploids like "King Alfred" (1899), the industry was well established, with trumpet daffodils dominating the market.<ref name=Zonneveld11/> The Royal Horticultural Society has been an important factor in promoting narcissi, holding the first Daffodil Conference in 1884,<ref name=DaffConf/> while the Daffodil Society, the first organisation dedicated to the cultivation of narcissi was founded in Birmingham in 1898. Other countries followed and the American Daffodil Society which was founded in 1954 publishes ''The Daffodil Journal'' quarterly, a leading trade publication.

Narcissi are now popular as ornamental plants for gardens, parks and as cut flowers, providing colour from the end of winter to the beginning of summer in temperate regions. They are one of the most popular spring flowers{{sfn|Huxley|Griffiths|Levy|1992}} and one of the major ornamental spring flowering bulb crops, being produced both for their bulbs and cut flowers, though cultivation of private and public spaces is greater than the area of commercial production.<ref name=Bastida/> Over a century of breeding has resulted in thousands of varieties and cultivars being available from both general and specialist suppliers.<ref name=Graham/> They are normally sold as dry bulbs to be planted in late summer and autumn. They are one of the most economically important ornamental plants.<ref name=Graham/><ref name=Bastida/> Plant breeders have developed some daffodils with double, triple, or ambiguously multiple rows and layers of segments.<ref name=RHSAZ /> Many of the breeding programs have concentrated on the corona (trumpet or cup), in terms of its length, shape, and colour, and the surrounding perianth<ref name=Mathew/> or even as in varieties derived from ''[[Biology:Narcissus poeticus|N. poeticus]]'' a very reduced form.

=== In gardens ===
While some wild narcissi are specific in terms of their ecological requirements, most garden varieties are relatively tolerant of soil conditions,{{sfn|Dana|Lerner|2001}} however very wet soils and clay soils may benefit from the addition of sand to improve drainage.{{sfn|Trinklein|2007}} The optimum soil is a neutral to slightly acid [[Chemistry:PH|pH]] of 6.5–7.0.{{sfn|Dana|Lerner|2001}}

Bulbs offered for sale are referred to as either 'round' or 'double nose'. Round bulbs are circular in cross section and produce a single flower stem, while double nose bulbs have more than one bulb stem attached at the base and produce two or more flower stems, but bulbs with more than two stems are unusual.<ref name=CNLA/> Planted narcissi bulbs produce daughter bulbs in the axil of the bulb scales, leading to the dying off the exterior scales.{{sfn|Dana|Lerner|2001}} To prevent planted bulbs forming more and more small bulbs, they can be dug up every 5–7 years, and the daughters separated and replanted separately, provided that a piece of the basal plate, where the rootlets are formed, is preserved. For daffodils to flower at the end of the winter or early spring, bulbs are planted in autumn (September–November). This plant does well in ordinary soil but flourishes best in rich soil. Daffodils like the sun but also accept partial shade exposure.{{citation needed|date=July 2019}}

Narcissi are well suited for planting under small thickets of trees, where they can be grouped as 6–12 bulbs.{{sfn|Singh|2006|loc=[https://books.google.com/books?id=Bfb1T6QbfaAC&pg=251 ''Narcissus'' p.&nbsp;251]}} They also grow well in perennial borders,{{sfn|Dana|Lerner|2001}} especially in association with day lilies which begin to form their leaves as the narcissi flowers are fading.{{sfn|Trinklein|2007}} A number of wild species and hybrids such as "Dutch Master", "Golden Harvest", "Carlton", "Kings Court" and "Yellow Sun" naturalise well in lawns,{{sfn|Dana|Lerner|2001}} but it is important not to mow the lawn till the leaves start to fade, since they are essential for nourishing the bulb for the next flowering season.{{sfn|Dana|Lerner|2001}} Blue [[Biology:Scilla|Scilla]] and [[Biology:Muscari|Muscari]] which also naturalise well in lawns and flower at the same time as narcissus, make an attractive contrast to the yellow flowers of the latter. Unlike [[Biology:Tulip|tulip]]s, narcissi bulbs are not attractive to rodents and are sometimes planted near tree roots in orchards to protect them.{{sfn|Steinbergs|2008}}

=== Propagation ===
The commonest form of commercial propagation is by [[Biology:Twin-scaling|twin-scaling]], in which the bulbs are cut into many small pieces but with the two scales still connected by a small fragment of the basal plate. The fragments are disinfected and placed in nutrient media. Some 25–35 new plants can be produced from a single bulb after four years. [[Earth:Micropropagation|Micropropagation]] methods are not used for commercial production but are used for establishing commercial stock.{{sfn|Chow|1993}} {{sfn|Okubo|Sochacki |2012|p=[https://books.google.com/books?id=5B-ucdbgA3wC&pg=PA107 107]}}

=== Breeding ===
For commercial use, varieties with a minimum stem length of {{convert|30|cm}} are sought, making them ideal for cut flowers. Florists require blooms that only open when they reach the retail outlet. For garden plants the objectives are to continually expand the colour palette and to produce hardy forms, and there is a particular demand for miniature varieties. The cultivars so produced tend to be larger and more robust than the wild types.{{sfn|Hanks|2002|loc=[https://books.google.com/books?id=4_kH_BffGDgC&pg=PA1 Hanks, "The biology of ''Narcissus''"], pp. 1–29}} The main species used in breeding are ''[[Biology:Narcissus bulbocodium|N. bulbocodium]]'', ''N. cyclamineus'', ''N. jonquilla'', ''[[Biology:Narcissus poeticus|N. poeticus]]'', ''[[Biology:Narcissus pseudonarcissus|N. pseudonarcissus]]'', ''[[Biology:Narcissus serotinus|N. serotinus]]'' and ''[[Biology:Narcissus tazetta|N. tazetta]]''.{{sfn|Okubo|Sochacki |2012|p=[https://books.google.com/books?id=5B-ucdbgA3wC&pg=PA105 105]}}

''Narcissus pseudonarcissus'' gave rise to trumpet cultivars with coloured tepals and corona, while its subspecies ''N. pseudonarcissus'' subsp. ''bicolor'' was used for white tepaled varieties. To produce large cupped varieties, ''N. pseudonarcissus'' was [[Biology:Hybrid|crossed]] with ''N. poeticus'', and to produce small cupped varieties back crossed with ''N. poeticus''. Multiheaded varieties, often called "Poetaz" are mainly hybrids of ''N. poeticus'' and ''N. tazetta''.{{sfn|Hanks|2002|loc=[https://books.google.com/books?id=4_kH_BffGDgC&pg=PA1 Hanks, "The biology of ''Narcissus''"], pp. 1–29}}

=== Classification ===
[[File:Narcissus - Cultivars.jpg|thumb|Range of ''Narcissus'' cultivars]]
For horticultural purposes, all ''Narcissus'' cultivars are split into 13 divisions as first described by Kington (1998),<ref name=Kington/> for the Royal Horticultural Society (RHS),<ref name="RHSAZ"/> based partly upon flower form (shape and length of corona), number of flowers per stem, flowering period and partly upon genetic background. Division 13, which includes wild daffodils, is the exception to this scheme.<ref name="RHSClass"/> The classification is a useful tool for planning planting. Most commercially available narcissi come from Divisions 1 (Trumpet), 2 (Large cupped) and 8 (Tazetta).

Growers register new daffodil cultivars by name and colour with the Royal Horticultural Society, which is the international registration authority for the genus.<ref name=RHSIRA/> Their ''International Daffodil Register'' is regularly updated with supplements available online<ref name=RHSIRA/> and is searchable.<ref name=Mathew/><ref name=RHSIRAS/> The most recent supplement (2014) is the sixth (the fifth was published in 2012).<ref name=Kington2008/> More than 27,000 names were registered as of 2008,<ref name=Kington2008/> and the number has continued to grow. Registered daffodils are given a division number and colour code<ref name=IDRI/> such as 5 W-W ("Thalia").<ref name=BBThalia/> In horticultural usage it is common to also find an unofficial Division 14: Miniatures, which although drawn from the other 13 divisions, have their miniature size in common.<ref name=BB14/> Over 140 varieties have gained the Royal Horticultural Society's Award of Garden Merit (See [[Biology:List of Award of Garden Merit narcissus|List of Award of Garden Merit narcissus]]).

====Colour code====
[[File:Narcissus Geranium.jpg|thumb|right|''Narcissus'' "Geranium" '''8 W-O''']]
Daffodil breeding has introduced a wide range of colours, in both the outer perianth tepal segment and the inner corona. In the registry, daffodils are coded by the colours of each of these two parts. Thus "Geranium", Tazetta (Division 8) as illustrated here with a white outer perianth and orange corona is classified as '''8 W-O'''.

== Toxicity ==
=== Pharmacology ===
All ''Narcissus'' species contain the [[Chemistry:Alkaloid|alkaloid]] poison [[Chemistry:Lycorine|lycorine]], mostly in the bulb but also in the leaves.<ref name="Pupils ill after bulb put in soup"/> Members of the monocot subfamily [[Biology:Amaryllidoideae|Amaryllidoideae]] present a unique type of alkaloids, the norbelladine alkaloids, which are 4-methylcatechol derivatives combined with [[Chemistry:Tyrosine|tyrosine]]. They are responsible for the poisonous properties of a number of the species. Over 200 different chemical structures of these compounds are known, of which 79 or more are known from ''Narcissus'' alone.<ref name=Martin/>

The toxic effects of ingesting ''Narcissus'' products for both humans and animals (such as cattle, goats, pigs, and cats) have long been recognised and they have been used in suicide attempts. Ingestion of ''N. pseudonarcissus'' or ''N. jonquilla'' is followed by salivation, acute abdominal pains, nausea, [[Medicine:Vomiting|vomiting]], and [[Medicine:Diarrhea|diarrhea]], then neurological and cardiac events, including trembling, convulsions, and [[Engineering:Paralysis|paralysis]]. Death may result if large quantities are consumed.

The toxicity of ''Narcissus'' varies with species, ''N. poeticus'' being more toxic than ''N. pseudonarcissus'', for instance. The distribution of toxins within the plant also varies, for instance, there is a five times higher concentration of alkaloid in the stem of ''[[Biology:Narcissus papyraceus|N. papyraceus]]'' than in the bulb, making it dangerous to herbivores more likely to consume the stem than the bulb, and is part of the plant's defence mechanisms. The distribution of alkaloids within tissues may also reflect defence against parasites.<ref name=Bastida/> The bulbs can also be toxic to other nearby plants, including roses, rice, and cabbages, inhibiting growth.<ref name=Bastida/> For instance placing cut flowers in a vase alongside other flowers shortens the life of the latter.<ref name=Kornienko/>

=== Poisoning ===
Many cases of poisoning or death have occurred when narcissi bulbs have been mistaken for [[Biology:Leek|leek]]s or [[Biology:Onion|onion]]s and cooked and eaten. Recovery is usually complete in a few hours without any specific intervention. In more severe cases involving ingestion of large quantities of bulbs, [[Physics:Activated carbon|activated carbon]], salts and laxatives may be required, and for severe symptoms intravenous [[Chemistry:Atropine|atropine]] and emetics or stomach pumping may be indicated. However, ingestion of large quantities accidentally is unusual because of a strong unpleasant taste. When narcissi were compared with a number of other plants not normally consumed by animals, narcissi were the most repellent, specifically ''N. pseudonarcissus''. Consequently, narcissus alkaloids have been used as repellents and may also discourage fungi, molds, and bacteria.<ref name=Bastida/>

On 1 May 2009, a number of schoolchildren fell ill at Gorseland Primary School in Martlesham Heath, Suffolk, England, after a daffodil bulb was added to soup during a cookery class.<ref name="Pupils ill after bulb put in soup"/>

=== Topical effects ===
One of the most common [[Medicine:Dermatitis|dermatitis]] problems for flower pickers, packers, florists, and gardeners, "daffodil itch", involves dryness, fissures, scaling, and [[Medicine:Erythema|erythema]] in the hands, often accompanied by [[Biology:Ungual|subungual]] hyperkeratosis (thickening of the skin beneath the nails). It is blamed on exposure to [[Chemistry:Calcium oxalate|calcium oxalate]], [[Chemistry:Chelidonic acid|chelidonic acid]] or alkaloids such as [[Chemistry:Lycorine|lycorine]] in the sap, either due to a direct irritant effect or an allergic reaction.<ref name=Floridata/><ref name="Botanical Dermatology"/> It has long been recognised that some cultivars provoke dermatitis more readily than others. ''N. pseudonarcissus'' and the [[Biology:Cultivar|cultivar]]s "Actaea", "Camparelle", "Gloriosa", "Grande Monarque", "Ornatus", "Princeps" and "Scilly White" are known to do so.<ref name=Bastida/><ref name=Schmidt/>

If bulb extracts come into contact with wounds, both central nervous system and cardiac symptoms may result. The scent can also cause toxic reactions such as headaches and vomiting from ''N. bulbocodium''.<ref name=Bastida/>

==Uses==
=== Traditional medicine ===
Despite the lethal potential of ''Narcissus'' alkaloids, they have been used for centuries as [[Medicine:Traditional medicine|traditional medicine]]s for a variety of complaints, including cancer. Plants thought to be ''[[Biology:Narcissus poeticus|N. poeticus]]'' and ''[[Biology:Narcissus tazetta|N. tazetta]]'' are described in the Bible in the treatment for what is thought to be cancer.<ref name=Kornienko/>{{sfn|Atta-ur-Rahman|1998|loc=[https://books.google.com/books?id=Wjy24u4ubiUC&pg=PA391 Bastida ''et al.'' ''Narcissus'' alkaloids p.&nbsp;391]}}{{sfn|Pettit et al.|1990}}{{sfn|Hartwell|1967}} In the Classical Greek world [[Biography:Hippocrates|Hippocrates]] (ca. B.C. 460–370) recommended a pessary prepared from narcissus oil for uterine tumors, a practice continued by Pedanius Dioscorides (ca. A.D. 40–90) and Soranus of Ephesus (A.D. 98–138) in the first and second centuries A.D., while the [[History:Ancient Rome|Roman]] Pliny the Elder (A.D. 23–79), advocated topical use.<ref name=Kornienko/> The bulbs of ''N. poeticus'' contain the antineoplastic agent narciclasine. This usage is also found in later Arabian, North African, Central American and Chinese medicine during the [[History:Middle Ages|Middle Ages]].<ref name=Kornienko/> In China [[Biology:Narcissus tazetta|N. tazetta]] var. chinensis was grown as an ornamental plant but the bulbs were applied topically to tumors in traditional folk medicine. These bulbs contain pretazettine, an active antitumor compound.<ref name=Bastida/>{{sfn|Hartwell|1967}}<ref name=Ingrassia/>

''Narcissus'' products have received a variety of other uses. The Roman physician Aulus Cornelius Celsus listed narcissus root in ''[[Medicine:De Medicina|De Medicina]]'' among [[Biology:Herbalism|medical herbs]], described as emollient, erodent, and "powerful to disperse whatever has collected in any part of the body". N. tazetta bulbs were used in Turkey as a remedy for abscesses in the belief they were antiphlogistic and [[Biology:Analgesic|analgesic]]. Other uses include the application to wounds, strains, painful joints, and various local ailments as an [[Medicine:Ointment|ointment]] called 'Narcissimum'. Powdered flowers have also been used medically, as an emetic, a [[Chemistry:Decongestant|decongestant]] and for the relief of [[Medicine:Dysentery|dysentery]], in the form of a syrup or infusion. The French used the flowers as an antispasmodic, the Arabs the oil for baldness and also an aphrodisiac. In the eighteenth century the Irish [[Biology:Herbal|herbal]] of John K'Eogh recommended pounding the roots in honey for use on burns, bruises, dislocations and freckles, and for drawing out thorns and splinters. ''N. tazetta'' bulbs have also been used for contraception, while the flowers have been recommended for hysteria and [[Medicine:Epilepsy|epilepsy]].<ref name=Bastida/> In the traditional Japanese medicine of kampo, wounds were treated with narcissus root and [[Chemistry:Wheatpaste|wheat flour paste]];<ref name=Altomonte/> the plant, however, does not appear in the modern kampo herb list.

There is also a long history of the use of ''Narcissus'' as a [[Chemistry:Stimulant|stimulant]] and to induce [[Unsolved:Trance|trance]] like states and hallucinations. Sophocles referred to the narcissus as the "Chaplet of the infernal Gods",<ref name=Prior/> a statement frequently wrongly attributed to [[Biography:Socrates|Socrates]] (see Antiquity).<ref name=Bastida/>

=== Biological properties ===
Extracts of ''Narcissus'' have demonstrated a number of potentially useful biological properties including [[Biology:Antiviral drug|antiviral]], prophage induction, antibacterial, [[Biology:Fungicide|antifungal]], antimalarial, insecticidal, cytotoxic, antitumor, antimitotic, antiplatelet, hypotensive, emetic, acetylcholine esterase inhibitory, antifertility, antinociceptive, [[Chemistry:Chronotropic|chronotropic]], [[Biology:Pheromone|pheromone]], plant growth inhibitor, and allelopathic.<ref name=Bastida/> An [[Chemistry:Ethanol|ethanol]] extract of ''Narcissus'' bulbs was found effective in one mouse model of [[Biology:Nociception|nociception]], para-benzoquinone induced abdominal constriction, but not in another, the hot plate test.<ref name=Cakici/> Most of these properties are due to alkaloids, but some are also due to mannose-binding lectins. The most-studied alkaloids in this group are [[Chemistry:Galantamine|galantamine]] (galanthamine),{{sfn|CID9651|2015}} [[Chemistry:Lycorine|lycorine]], narciclasine, and pretazettine.

It is likely that the traditional use of narcissi for the treatment of cancer was due to the presence of isocarbostyril constituents such as [[Chemistry:Narciclasine|narciclasine]], [[Chemistry:Pancratistatin|pancratistatin]] and their congeners. ''N. poeticus'' contains about 0.12g of narciclasine per kg of fresh bulbs.<ref name=Kornienko/>

Acetylcholine esterase inhibition has attracted the most interest as a possible therapeutic intervention, with activity varying by a thousandfold between species, and the greatest activity seen in those that contain galantamine or epinorgalanthamine.<ref name=Ronsted2008/>

The [[Biology:Rodent|rodent]] repellant properties of ''Narcissus'' alkaloids have been utilised in horticulture to protect more vulnerable bulbs.<ref name=Protectrodent/>

=== Therapeutics ===
[[File:Field of Daffodils - Pentre Meyrick - geograph.org.uk - 1260139.jpg|thumb|Daffodils growing in Wales]]
Of all the alkaloids, only galantamine has made it to therapeutic use in humans, as the drug galantamine for Alzheimer's disease. Galantamine is an acetylcholine esterase inhibitor which crosses the blood brain barrier and is active within the [[Biology:Central nervous system|central nervous system]].<ref name=Bastida/> Daffodils are grown commercially near Brecon in Powys, Wales, to produce [[Chemistry:Galantamine|galantamine]].<ref name=BBC2008/>

=== Commercial uses ===
Throughout history the scent of narcissi has been an important ingredient of perfumes, a quality that comes from essential oils rather than alkaloids.<ref name=Bastida/> Narcissi are also an important horticultural crop,<ref name=Zonneveld/><ref name=Dweck/> and source of cut flowers (floriculture).

[[File:Narcissus field near Keukenhof.jpg|thumb|Daffodil production in the Netherlands]]
The Netherlands, which is the most important source of flower bulbs worldwide is also a major centre of narcissus production. Of 16,700 hectares (ha) under cultivation for flower bulbs, narcissi account for about 1,800 hectares. In the 1990s narcissus bulb production was at 260&nbsp;million, sixth in size after tulips, gladioli, [[Biology:Iris (plant)|irises]], crocuses and lilies and in 2012 it was ranked third.{{sfn|Okubo|Sochacki |2012|p=[https://books.google.com/books?id=5B-ucdbgA3wC&pg=PA103 103]}} About two-thirds of the area under cultivation is dedicated to about 20 of the most popular varieties. In the 2009/2010 season, 470 cultivars were produced on 1578&nbsp;ha. By far the largest area cultivated is for the miniature 'Tête-à-Tête', followed at some distance by 'Carlton'. The largest production cultivars are shown in Table II.{{sfn|Okubo|Sochacki |2012|p=[https://books.google.com/books?id=5B-ucdbgA3wC&pg=PA106 106]}}

"Carlton" and "Ice Follies" (Division 2: Large cup) have a long history of cultivation, together with "Dutch Master" and "Golden Harvest" (1: yellow). "Carlton" and "Golden Harvest" were introduced in 1927, and "Ice Follies" in 1953. "Carlton", with over 9 billion bulbs (350 000 tons), is among the more numerous individual plants produced in the world.{{sfn|Mabberley|2008|loc=[https://books.google.com/books?id=ZFFgAgAAQBAJ&pg=PA571 Narcissus], p. 571}} The other major areas of production are the {{wipe|United States}},{{sfn|Okubo|Sochacki |2012|p=[https://books.google.com/books?id=5B-ucdbgA3wC&pg=PA103 103]}} [[Place:Israel|Israel]] which exported 25&nbsp;million ''[[Biology:Narcissus tazetta|N. tazetta]]'' cultivar bulbs in 2003,{{sfn|Okubo|Sochacki |2012|p=[https://books.google.com/books?id=5B-ucdbgA3wC&pg=PA106 106]}} and the {{wipe|United Kingdom}}.

In the United Kingdom a total of 4100&nbsp;ha were planted with bulbs, of which 3800&nbsp;ha were Narcissi, the UK's most important bulb crop, much of which is for export,{{sfn|Alford|2000|loc=[https://books.google.com/books?id=rxw5JvD7MN4C&pg=PA542 p. 542]}} making this the largest global production centre, about half of the total production area. While some of the production is for forcing, most is for dry bulb production. Bulb production and forcing occurs in the East, while production in the south west is mainly for outdoor flower production.{{sfn|Alford|2000|loc=[https://books.google.com/books?id=rxw5JvD7MN4C&pg=PA551 p. 551]}} The farm gate value was estimated at £10m in 2007.{{sfn|Fellows|Hanks|2007}}

[[File:Kuekenhoff 006.jpg|thumb|Narcissi growing at Keukenhof]]
Production of both bulbs and cut flowers takes place in open fields in beds or ridges, often in the same field, allowing adaptation to changing market conditions. Narcissi grow best in mild maritime climates. Compared to the United Kingdom, the harsher winters in the Netherlands require covering the fields with straw for protection. Areas with higher rainfall and temperatures are more susceptible to diseases that attack crops. Production is based on a 1 (UK) or 2 (Netherlands) year cycle. Optimal soil [[Chemistry:PH|pH]] is 6.0–7.5. Prior to planting disinfection by hot water takes place, such as immersion at 44.4&nbsp;°C for three hours.{{sfn|Okubo|Sochacki |2012|p=[https://books.google.com/books?id=5B-ucdbgA3wC&pg=PA107 107]}}

Bulbs are harvested for market in the summer, sorted, stored for 2–3 weeks, and then further disinfected by a hot (43.5&nbsp;°C) bath. This eliminates infestations by narcissus fly and nematodes. The bulbs are then dried at a high temperature, and then stored at 15.5&nbsp;°C.{{sfn|Hanks|2002|loc=[https://books.google.com/books?id=4_kH_BffGDgC&pg=PA1 Hanks, "The biology of ''Narcissus''"], pp. 1–29}} The initiation of new flower development in the bulb takes place in late spring before the bulbs are lifted, and is completed by mid summer while the bulbs are in storage. The optimal temperature for initiation is 20&nbsp;°C followed by cooling to 13&nbsp;°C.{{sfn|Okubo|Sochacki |2012|p=[https://books.google.com/books?id=5B-ucdbgA3wC&pg=PA104 104]}}

Traditionally, sales took place in the daffodil fields prior to harvesting the bulbs, but today sales are handled by Marketing Boards although still before harvesting. In the Netherlands there are special exhibition gardens for major buyers to view flowers and order bulbs, some larger ones may have more than a thousand narcissus varieties on display. While individuals can visit these gardens they cannot buy bulbs at [[Finance:Retail|retail]], which are only available at wholesale, usually at a minimum of several [[Hundredweight|hundredweight]]. The most famous display is at Keukenhof, although only about 100 narcissus varieties are on display there.

====Forcing====
There is also a market for forced blooms, both as cut flowers and potted flowers through the winter from Christmas to Easter, the long season requiring special preparation by growers.

===== Cut flowers =====
For cut flowers, bulbs larger than 12&nbsp;cm in size are preferred. To bloom in December, bulbs are harvested in June to July, dried, stored for four days at 34&nbsp;°C, two weeks at 30 and two weeks at 17–20&nbsp;°C and then placed in cold storage for precooling at 9 degrees for about 15–16 weeks. The bulbs are then planted in light compost in crates in a greenhouse for forcing at 13&nbsp;°C–15&nbsp;°C and the blooms appear in 19–30 days.{{sfn|Hanks|2002|loc=[https://books.google.com/books?id=4_kH_BffGDgC&pg=PA1 Hanks, "The biology of ''Narcissus''"], pp. 1–29}}{{sfn|Okubo|Sochacki |2012|p=[https://books.google.com/books?id=5B-ucdbgA3wC&pg=PA107 107]}}

===== Potted flowers =====
For potted flowers a lower temperature is used for precooling (5&nbsp;°C for 15 weeks), followed by 16&nbsp;°C–18&nbsp;°C in a greenhouse. For later blooming (mid- and late-forcing), bulbs are harvested in July to August and the higher temperatures are omitted, being stored a 17–20&nbsp;°C after harvesting and placed in cold storage at 9&nbsp;°C in September for 17–18 (cut flowers) or 14–16 (potted flowers) weeks. The bulbs can then be planted in cold frames, and then forced in a greenhouse according to requirements.{{sfn|Okubo|Sochacki |2012|p=[https://books.google.com/books?id=5B-ucdbgA3wC&pg=PA107 107]}} ''[[Biology:Narcissus tazetta|N. tazetta]]'' and its cultivars are an exception to this rule, requiring no cold period. Often harvested in October, bulbs are lifted in May and dried and heated to 30&nbsp;°C for three weeks, then stored at 25&nbsp;°C for 12 weeks and planted. Flowering can be delayed by storing at 5&nbsp;°C–10&nbsp;°C.{{sfn|Okubo|Sochacki |2012|p=[https://books.google.com/books?id=5B-ucdbgA3wC&pg=PA108 108]}}

== Culture ==

=== Symbols ===
[[File:Narcissus 'Thalia'.jpg|thumb|N. triandrus 'Thalia', considered a grave flower]]

The daffodil is the national flower of Wales, associated with Saint David's Day (March 1). The narcissus is also a national flower symbolising the new year or ''Nowruz'' in the Iranian culture.

In the West the narcissus is perceived as a symbol of vanity, in the East as a symbol of wealth and good fortune {{See below|{{section link||Eastern cultures}}, below}}, while in Persian literature, the narcissus is a symbol of beautiful eyes.

In western countries the daffodil is also associated with spring festivals such as [[Religion:Lent|Lent]] and its successor Easter. In Germany the wild narcissus, ''N. pseudonarcissus'', is known as the ''Osterglocke'' or "Easter bell." In the United Kingdom the daffodil is sometimes referred to as the Lenten lily.<ref name="Hereford" /><ref name="Oxford" /><ref group="Note">Rarely "Lentern", especially ecclesiastical usage as here, or dialect, particularly Scottish {{harv|Masefield|2014|loc=[https://books.google.com/books?id=V8l8AwAAQBAJ&pg=PA104 p. 104]}}{{harv|Jamieson|1879|loc=[http://www.forgottenbooks.com/readbook_text/An_Etymological_Dictionary_of_the_Scottish_Language_Illustrating_the_v1_1000804762/283 Care Sonday vol I p. 284]}}{{harv|Wright|1905|loc=[https://books.google.com/books?id=_R8QAwAAQBAJ&pg=PA575 vol 3 H–L, Lentren p. 575]}}</ref>

Although prized as an ornamental flower, some people consider narcissi unlucky, because they hang their heads implying misfortune.<ref name="Bastida" /> White narcissi, such as ''N triandrus'' "Thalia", are especially associated with death, and have been called grave flowers.<ref name="Paghat" /><ref name="Kandeler" /> In Ancient Greece narcissi were planted near tombs, and Robert Herrick describes them as portents of death, an association which also appears in the myth of [[Religion:Persephone|Persephone]] and the [[Unsolved:Underworld|underworld]] {{See below|{{section link||Art}}, below}}.

=== Art ===
==== Antiquity ====
[[File:Demeter rejoiced, for her daughter was by her side.jpg|thumb|upright|Demeter and Persephone surrounded by daffodils - "''Demeter rejoiced, for her daughter was by her side''"]]
The decorative use of narcissi dates as far back as ancient Egyptian tombs, and frescoes at Pompeii.{{sfn|Jashemski|Meyer|2002| p=131}} They are mentioned in the King James Version of the Bible<ref name=Isaiah/> as the [[Biology:Rose of Sharon|Rose of Sharon]]<ref name=Dweck/><ref name=McClintock/><ref name=WFI1/><ref name=WFI2/> and make frequent appearances in classical literature.{{sfn|Hale|1757|loc=[https://www.biodiversitylibrary.org/item/131789#page/585/mode/1up pp. 495–496]}}

==== Greek culture ====
The narcissus appears in two Graeco-Roman myths, that of the youth [[Philosophy:Narcissus (mythology)|Narcissus]] who was turned into the flower of that name, and of the Goddess [[Religion:Persephone|Persephone]] snatched into the [[Unsolved:Greek underworld|Underworld]] by the god [[Religion:Hades|Hades]] while picking the flowers. The narcissus is considered sacred to both Hades and Persephone,<ref name="Ruskin" /> and grows along the banks of the river [[Unsolved:Styx|Styx]] in the underworld.<ref name="Kandeler" />

The Greek poet Stasinos mentioned them in the ''Cypria'' amongst the flowers of Cyprus.{{sfn|Cyrino|2010|loc=[https://books.google.com/books?id=dhv2AV3eTsUC&pg=PA63 p. 63]}} The legend of Persephone comes to us mainly in the seventh century BC Homeric Hymn ''To Demeter'',<ref name="DemeterNagy" /> where the author describes the narcissus, and its role as a lure to trap the young Persephone. The flower, she recounts to her mother was the last flower she reached for before being seized.

Other Greek authors making reference to the narcissus include Sophocles and [[Philosophy:Plutarch|Plutarch]]. Sophocles, in ''Oedipus at Colonus'' utilises narcissus in a symbolic manner, implying fertility,{{sfn|Markantonatos|2002|loc=[https://books.google.com/books?id=faciAAAAQBAJ&pg=PA186 p. 186]}} allying it with the cults of [[Religion:Demeter|Demeter]] and her daughter [[Religion:Persephone|Kore (Persephone)]],<ref name="OedCol" /> and by extension, a symbol of death.{{sfn|Markantonatos|2002|loc=[https://books.google.com/books?id=faciAAAAQBAJ&pg=PA206 pp. 206–207]}} Jebb comments that it is ''the flower of imminent death'' with its fragrance being narcotic, emphasised by its pale white colour. Just as Persephone reaching for the flower heralded her doom, the youth Narcissus gazing at his own reflection portended his own death.<ref name="OedCol" /> Plutarch refers to this in his ''Symposiacs'' as numbing the nerves causing a heaviness in the limbs.<ref name="Plutarch" /> He refers to Sophocles' "crown of the great Goddesses", which is the source of the English phrase "Chaplet of the infernal Gods" incorrectly attributed to [[Biography:Socrates|Socrates]].<ref name="Prior" />

A passage by Moschus, describes fragrant narcissi.{{sfn|Moschus|1919|loc=l. 65}}{{sfn|Earley|1877}}{{sfn|Theocritus|Bion|Moschus|1880|loc=[https://books.google.com/books?id=3okOAAAAQAAJ&pg=PA183 Moschus. Idyll II, Europa and the Bull (pp. 181–187) at p. 183]}} [[Biography:Homer|Homer]] in his ''[[Religion:Odyssey|Odyssey]]''<ref name="Homer1" /><ref name="HomerGrk1" /><ref name="Homer2" /><ref name="HomerGrk2" /> described the underworld as having Elysian meadows carpeted with flowers, thought to be narcissus, as described by [[Biography:Theophrastus|Theophrastus]].<ref name="Dweck" /><ref>{{cite web |url=http://www.merriam-webster.com/dictionary/asphodel |title=Asphodel |work=Merriam-Webster Dictionary |access-date=20 November 2014}}</ref><ref group="Note">The Asphodel of the Greek underworld has been variously associated with the white ''[[Biology:Asphodelus ramosus|Asphodelus ramosus]]'' ({{Harvtxt|Macmillan|1887}}) or the yellow ''[[Biology:Asphodeline lutea|Asphodeline lutea]]'' ({{Harvtxt|Graves|1949}}), previously classified as ''Asphodelus luteus''.</ref> A similar account is provided by Lucian describing the flowers in the underworld.<ref name="Lucian1" /><ref name="Lucian2"/><ref name="LucianEng" /> The myth of the youth Narcissus is also taken up by Pausanias. He believed that the myth of Persephone long antedated that of Narcissus, and hence discounted the idea the flower was named after the youth.<ref name="Pausanias" />

==== Roman culture ====
Virgil, the first known [[History:Ancient Rome|Roman]] writer to refer to the narcissus, does so in several places, for instance twice in the ''Georgics''.<ref name=DavidsonVirgil1/> Virgil refers to the cup shaped corona of the narcissus flower, allegedly containing the tears of the self-loving youth [[Philosophy:Narcissus (mythology)|Narcissus]].<ref name=DavidsonVirgil2/> [[Biography:John Milton|Milton]] makes a similar analogy "''And Daffodillies fill their Cups with Tears''".<ref name=Lycidas/> Virgil also mentions narcissi three times in the ''Eclogues''.<ref name=DavidsonVirgil5/><ref name=DavidsonVirgil3/>

The poet Ovid also dealt with the mythology of the narcissus. In his ''Metamorphoses'', he recounts the story of the youth Narcissus who, after his death, is turned into the flower,<ref name=Ovidmet/><ref name=Klinemet/> and it is also mentioned in Book 5 of his poem ''Fasti''.<ref name=Ovidfast/><ref name=Klinefast/> This theme of metamorphosis was broader than just ''Narcissus''; for instance see [[Biology:Crocus|crocus]], [[Biology:Laurus nobilis|laurel]] and [[Biology:Hyacinth (plant)|hyacinth]].<ref name=Panofsky/>

==== Western culture ====
{{Quote box|title=''I wandered lonely as a Cloud''|align=right|border=2px|bgcolor = Cornsilk|width=220|fontsize=75%

| quote=
<poem><br/>[[Image:Decorative I.jpg|15px|alt=I]] wandered lonely as a Cloud
That floats on high o'er Vales and Hills,
When all at once I saw a crowd
A host of dancing Daffodils;
Along the Lake, beneath the trees,
Ten thousand dancing in the breeze.

The waves beside them danced, but they
Outdid the sparkling waves in glee: –
A poet could not but be gay
In such a laughing company:
I gaz'd – and gaz'd – but little thought
What wealth the shew to me had brought:

For oft when on my couch I lie
In vacant or in pensive mood,
They flash upon that inward eye
Which is the bliss of solitude,
And then my heart with pleasure fills,
And dances with the Daffodils.</poem>|source=William Wordsworth (1804 version)<ref name=WW1/> [[File:282 Hager Bot Unterricht 1885.png|center|30px]]}}
Although there is no clear evidence that the flower's name derives directly from the Greek myth, this link between the flower and the myth became firmly part of western culture. The narcissus or daffodil is the most loved of all English plants,{{sfn|Ellacombe|1884|loc=[https://archive.org/details/plantloregarden01ellagoog/page/n91 <!-- pg=73 --> Daffodils], p. 73}} and appears frequently in English literature. Many English writers have referred to the cultural and symbolic importance of ''Narcissus''{{sfn|Anonymous|1823}}{{sfn|Burbidge|1875}}{{sfn|Barr|Burbidge|1884}}{{sfn|Ellacombe|1884}}). No flower has received more poetic description except the [[Biology:Rose|rose]] and the lily, with poems by authors from John Gower, Shakespeare, Milton (see Roman culture, above), Wordsworth, [[Biography:Percy Bysshe Shelley|Shelley]] and Keats. Frequently the poems deal with self-love derived from Ovid's account.<ref name=PoetryNarcissus/>{{sfn|Ellacombe|1884|loc=[https://archive.org/details/plantloregarden01ellagoog/page/n92 <!-- pg=74 --> Daffodils], p. 4}} Gower's reference to the yellow flower of the legend has been assumed to be the daffodil or ''Narcissus'',{{sfn|Ellacombe|1884|loc=[https://archive.org/details/plantloregarden01ellagoog/page/n92 <!-- pg=74 --> Daffofils], p. 74}} though as with all references in the older literature to the flower that sprang from the youth's death, there is room for some debate as to the exact species of flower indicated, some preferring ''[[Biology:Crocus|Crocus]]''.{{sfn|Yeager|1990|loc=[https://books.google.com/books?id=SmH4Q4GMyHEC&pg=PA133 Transformations], pp. 133–135}} Spenser announces the coming of the Daffodil in ''Aprill'' of his ''Shepheardes Calender'' (1579).{{sfn|Spenser|1579|loc=[http://www.luminarium.org/renascence-editions/aprill.html Aprill ''l.'' 140]}}

Shakespeare, who frequently uses flower imagery,{{sfn|Ellacombe|1884}} refers to daffodils twice in ''The Winter's Tale'' {{sfn|Shakespeare|1623|loc=Perdita, IV 4}} and also ''The Two Noble Kinsmen''. Robert Herrick alludes to their association with death in a number of poems.<ref name=Herrick2/><ref name=Herrick1/> Among the English romantic movement writers none is better known than [[Biography:William Wordsworth|William Wordsworth]]'s short 1804 poem ''I Wandered Lonely as a Cloud''<ref name=WW1/> which has become linked in the popular mind with the daffodils that form its main image.<ref name=Dweck/><ref name=Kandeler/><ref name=PoetryNarcissus/><ref name=WTrust/> Wordsworth also included the daffodil in other poems.<ref name=WW2/> Yet the description given of daffodils by his sister, Dorothy is just as poetic, if not more so,{{sfn|Ellacombe|1884|loc=[https://archive.org/details/plantloregarden01ellagoog/page/n94 <!-- pg=76 --> Daffodils], p. 76}} just that her poetry was prose and appears almost an unconscious imitation of the first section of the Homeric ''Hymn to Demeter'' (see Greek culture, above).{{sfn|Wordsworth|1853|p=[https://books.google.com/books?id=SJTfAAAAMAAJ&pg=PA112 112], Issue 183, January, p. 112}}{{sfn|Ellacombe|1884|loc=[https://archive.org/details/plantloregarden01ellagoog/page/n94 <!-- pg=76 --> Daffodils], p. 76}}{{sfn|Wordsworth|1802}} Among their contemporaries, Keats refers to daffodils among those things capable of bringing "joy for ever".{{sfn|Keats|1818}}

More recently A. E. Housman, using one of the daffodil's more symbolic names (see Symbols), wrote ''The Lent Lily'' in ''A Shropshire Lad'', describing the traditional Easter death of the daffodil.{{sfn|Housman|1896|loc=XXIX ''The Lent Lily'', 1896}}

In ''Black Narcissus'', Rumer Godden describes the disorientation of English nuns in the Indian Himalayas, and gives the plant name an unexpected twist, alluding both to [[Philosophy:Narcissism|narcissism]] and the effect of the perfume ''Narcisse Noir'' (Caron) on others. The novel was later adapted into the 1947 British film of the same name. The narcissus also appears in German literature such as that of Paul Gerhardt.<ref name=Gerhardt/>

In the visual arts, narcissi are depicted in three different contexts, mythological (Narcissus, Persephone), floral art, or landscapes. The Narcissus story has been popular with painters and the youth is frequently depicted with flowers to indicate this association.<ref name=SOED/><ref name=Panofsky/> The Persephone theme is also typified by Waterhouse in his ''Narcissus'', the floral motif by van Scorel and the landscape by Van Gogh's ''Undergrowth''.

Narcissi first started to appear in western art in the [[History:Late Middle Ages|late Middle Ages]], in panel paintings, particularly those depicting crucifixion. For instance that of the Westfälischer Meister in Köln in the Wallraf-Richartz-Museum, Cologne,<ref name=Cologne/> where daffodils symbolise not only death but also hope in the [[Unsolved:Resurrection|resurrection]], because they are perennial and bloom at Easter.<ref name=Kandeler/><ref name=resur/><ref name=Stuttgart/>

The Japanese novel ''[[Software:Narcissu|Narcissu]]'' contains many references to the narcissus, where the main characters set out for the famed narcissus fields on Awaji Island.{{sfn|Awaji|2006|loc=[http://www.eonet.ne.jp/~t-suisen/index.html Awaji Tachikawa Narcissus Farmland]}}{{sfn|Awaji|2006|loc=[http://www.city.minamiawaji.hyogo.jp/soshiki/shoukou/suisenkyou.html Nada Kurokawa Narcissus Field]}}

The word "daffodil" has been used widely in popular culture, from Dutch cars ([[Engineering:DAF Daffodil|DAF Daffodil]]) to Swedish rock bands (The Daffodils) to slurs against homosexuals and cross-dressers (as in the film ''J.
