Iris tubergeniana is a species in the genus Iris, it is also in the subgenus Scorpiris. It is a bulbous perennial from Central Asia, in the former states of USSR (Uzbekistan, Tajikistan, Turkestan and Kazakhstan). It has pale green, pointed or sickle shaped leaves, short flowering stem holding 1-3 spring flowers in shades of yellow.

Description

Iris tubergeniana has a similar form to Iris orchioides and Iris caucasica.[2] It has a slender bulb,[2] about 2 cm thick,[3] with cord-like roots.[4] It has generally about 6 leaves, 2.5-3 in tall, 0.5-2 in wide (1.5-2.5 cm) at the widest point,[4][2][3] which are almost fully mature at flowering time.[5] They are pale green,[3] - light glaucous green, pointed or sickle shaped,[4] striated, with a margin.[2] The margin is scabrous/horned.[3] The short flowering stem is about 10–15 cm (4 in) high at flowering time.[4][2][3] It has 1-3 flowers,[4][6] blooming between March and April,[3][7] which are unscented.[4][3] It has a perianth tube measuring between 4.5–5 cm long, which is tinged slightly greenish purple.[4] It has (5.6 cm wide) flowers,[4][5] in shades of yellow, from deep yellow,[6] to bright yellow[4] to greenish-yellow.[7] The falls are about 1.5in long,[2] and have a frilled, dissected beard-like crest,[8] with violet-green spots on the sides of the ridge.[5][3] It has very small standards (about 10 mm).[4][2] It has (a seed capsule) fruits which appear in late spring and early summer.[4]

Taxonomy

It was published by Sir Michael Foster as Iris tubergeniana in Gardeners Chronicles, Series 3 in 1899.[9] It was named after the bulb company of 'Van Tubergen' from Haarlem, the Netherlands who introduced to the UK.[4]

In 1941, Alexi Vvedenski published it as Juno tubergeniana in 'Flora Uzbekistan' (edited by Schreder).[10] This was later re-classified as a synonym as Juno's were re-classed as part of the iris species.

It was also cited in 'The Plantsman' in 2003, on page 54.[11]

Iris tubergeniana is now an accepted name by the RHS,[11] and it was verified by United States Department of Agriculture and the Agricultural Research Service on 3 October 2014.[12]

Native

Iris tubergeniana is found in Central Asia and the former states of USSR,[5][6] within Uzbekistan,[12] (including on Chimgan,[13] and beside the river Syr Darya ,[8]) Tajikistan and Turkestan,[5][14] and on Karatau in Kazakhstan.[4] It can also be found near the town of Dzabaghly near the Aksu Canyon in the Tien Shen Mountains.[15]

Habitat

They grow best in the red clay and gravelly slopes of the foothills of mountains.[5][3][7]

Cultivation

It is better grown in an alpine house, but it could be grown outside in sunny sheltered sites.[5]

Culture

In 2012, the plant was part of a set of postage stamps issued in Uzbekistan, as part of the Chatkal Nature Reserve Series of 7 stamps,[16] also including Trichius fasciatus (Eurasian Bee Beetle) and Eurasian Eagle-owl (Bubo bubo).

Toxicity

Like many other irises, most parts of the plant are poisonous (including rhizome and leaves), if mistakenly ingested, it can cause stomach pains and vomiting. Also handling the plant may cause a skin irritation or an allergic reaction.[17]
