Iris filifolia

Iris filifolia is a species in the genus Iris, it is also in the subgenus Xiphium. It is a bulbous perennial from North Africa and Europe. It has thin leaves, summer flowers in shades of red-purple.

Description

It has 3 mm wide leaves,[4] which appear in the autumn.[5] It normally reaches a height of 10-16 inches (or 25–40 cm).[6] But can reach up to 45 cm tall.[5] It flowers between March and June.[6] Normally more than 2 flowers per stem.[7] When the flowering shoot comes out of the ground it is covered in a purple or white blotched sheath.[4] These then open up to revel red-purple flowers with orange spots,[6] or yellow stripe on the falls.[8]

Biochemistry

As most irises are diploid, having two sets of chromosomes, this can be used to identify hybrids and classification of groupings.[6] It has a chromosome count: 2n=32.[8]

Taxonomy

Its name means 'thread-leaved iris'.[9]

In Gibraltar, it is also known as the 'Narrow-leaved Purple Iris'.[10]

It is often mistakenly called 'Spanish Iris'.[11] The Spanish Iris is Iris xiphium.

In 1842, it was first described by Pierre Edmond Boissier in 'Voyage botanique en Espagne' Vol 2, on page 602.[12] Dykes notes that this description is incorrect.[13] It was also described in Curtis's Botanical Magazine No.5929 as 'Xiphion filifolium'.[3]

It was recorded in the Catalogue of Life in 2011,[2] and it was verified by United States Department of Agriculture Agricultural Research Service on 4 April 2003, and updated on 14 November 2005.[14]

Distribution and habitat

It is native to temperate regions of North Africa and Europe.[14]

Range

It was found originally on Sierra de Mijas,[15] and Sierra Bermeja in Spain , at 3,000–4,000 ft (910–1,220 m) above sea level.[3]

It is found within Africa, in Morocco, (near Tangier,[6][8]) and within Europe, in Southwestern Spain ,[14][6][8] and in Gibraltar.[10][8]

Habitat

Iris filifolia likes to grow in sandy areas.[16]

Cultivation

It is best grown in a bulb frame in the UK.[17]

It is known to be toxic like other bulbs in the genus.[18]

Cultivars

Several known cultivars are;[3]

  • 'A. Bloemaard' (dark blue)[19]
  • 'Filifolia'
  • 'Filifolia Alba'
  • 'Filifolia Elizabeth'
  • 'Filifolia Imperator'
  • 'Filifolia Praecox'
  • 'Latifolia'
  • 'Queen Of Gazelles'
  • 'Rex'

Hybrids

  • Iris filifolia var. latifolia (Foster) wide leaved variant [5]
  • Iris filifolia var. filifolia (Boiss) and thread-like leaved variant,
