Taxonomy

It was first published by Alexeï Ivanovitch Vvedenski in 'Flora URSS ' in 1935. Under the name 'Juno Vicaria'.
Iris vicaria is now the accepted name by the RHS, and it was verified by United States Department of Agriculture and the Agricultural Research Service on 3 October 2014.
It is very similar in form to Iris magnifica with pale violet flowers.
Around 1930, the Russian Government decided to sell various wild bulbs from its lands, to plant collectors of Europe and other countries. Large quantities of Lilium szovitsianum, various tulip species and other bulbs were dug up, transported and sold. A lot of iris bulbs labelled Iris warleyensis were found out to be mis-labeled by American bulb growers. Using Professor Fedtschenko's book,' 'Species of Wild Flowers of the U.S.S.R. they were found out to be Iris vicaria''.

Native

Iris vicaria comes from the Pamir Mountains and Alay Mountains of Central Asia.
It can also be found beside the Upper Varzob River, in the Pamir Mountain system of Tajikistan.
The mountains' spring thaw provides the year's main water for the irises and other plants in the area.
It can also be found in Uzbekistan, on the Hissar Mountains and Baisun Mountains, regions of Tajikistan.

Known culitvars

It is hardy to USDA Zone 6.
It prefers to be cultivated in well-drained soils containing lime, so that the water does not stay on the leaves. Similar to the cultivation conditions of Iris bucharica and Iris graeberiana.
It can grow in large pots or in the ground depending on the conditions.
Bulbs can be planted in early November, then protected over the winter by a thick mulch, which is scrapped away in the spring. Bulb nurseries lift the bulbs in July after the foliage has died away. Then they are stored in dry, gentle heated room until planting time.
