It has 4-5 dark green glaucous leaves which gradually taper to the apex, (falcate), They are clustered together at the base, and are 1-1.5 cm wide (close to the base). They also have a contrasting white edge or margin.
It grows up to a height of between 10–15 cm (4–6 in), including the flower.
It has a thick stem, which is between 3–5 cm long, hidden by the leaves, unbranched with 1-4 flowers. The blooms appear in April–May.
The non-scented flowers appear above a perianth tube of 3.5-4.5 cm long.

Taxonomy
It was originally published as Iris kuschakewiczi by Boris Fedtschenko in 'Bull. Jard. Bot. Petersb.' v. 158 (Bulletin of St. Petersburg Botanical Garden) in 1905.
In 1958, Petr Petrovich Poljakov re-published it as Juno kuschakewiczii in Fl. Kazakhst. 2: 249.
In 1939, it was suggested this was a form of Iris narynensis, but when Mathew published "The Iris" in 1981, he retained it as a separate species.
Iris kuschakewiczii is now an accepted name by the RHS.
It was named after a Russian botanist 'A. A. Kuschakewicz' who worked with N. J. Korolkov in 1872, and Boris Fedtschenko in 1873.
A. A. Kuschakewicz collected many plants in Turkestan and Central Asia.
It is mentioned in D.J. Mabberley portable plant books of 1997.
Native
In 1905, Iris kuschakewiczii was found in Turkestan, on the northern foothills of the Tien Shan Mountains of Central Asia.
It can be found on gravelly and rocky slopes, on the red-clay hills of Kazakhstan (on the north-western spurs of the Tien Shan).
It is also found in the Ala Archa National Park (25 km from the capital of Bishkek) of Kyrgyzstan.
