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 slightlly 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 prefer 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]
