Description
Iris tubergeniana has a similar form to Iris orchioides and Iris caucasica.[1]
It has a slender bulb,[1] about 2 cm thick.[2] With cord-like roots.[3]
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,[3][1][2] which are almost fully mature at flowering time.[4] They are pale green,[2] - light glaucous green, pointed or sickle shaped,[3] striated, with a margin.[1] The margin is scabrous/horned.[2]
The short flowering stem is about 10–15 cm (4 in) high at flowering time.[3][1][2]
It has 1-3 flowers,[3][5] blooming between March and April,[2][6] which are unscented.[3][2]
It has a perianth tube measuring between 4.5–5 cm long, which is tinged slightly greenish purple.[3] It has (5.6 cm wide) flowers,[3][4] in shades of yellow, from deep yellow,[5] to bright yellow[3] to greenish-yellow.[6]
The falls are about 1.5in long,[1] and have a frilled, dissected beard-like crest,[7] with violet-green spots on the sides of the ridge.[4][2] It has very small standards (about 10 mm).[3][1]
It has (a seed capsule) fruits which appear in late spring and early summer.[3]
Taxonomy
It was published by Sir Michael Foster as Iris tubergeniana in Gardeners Chronicles, Series 3 in 1899.[8] It was named after the bulb company of 'Van Tubergen' from Haarlem, the Netherlands who introduced to the UK.[3]
In 1941, Alexi Vvedenski published it as Juno tubergeniana in 'Flora Uzbekistan' (edited by Schreder).[9] 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.[10]
Iris tubergeniana is now an accepted name by the RHS,[10] and it was verified by United States Department of Agriculture and the Agricultural Research Service on 3 October 2014.[11]
Native
Iris tubergeniana is found in Central Asia and the former states of USSR,[4][5] within Uzbekistan,[11] (including on Chimgan,[12] and beside the river Syr Darya ,[7]) Tajikistan and Turkestan,[4][13] and on Karatau in Kazakhstan.[3] It can also be found near the town of Dzabaghly near the Aksu Canyon in the Tien Shen Mountains.[14]
Cultivation
It is better grown in an alpine house, but it could be grown outside in sunny sheltered sites.[4]
