Iris gatesii is a rhizomatous perennial Oncocyclus iris from the mountains of southeastern Turkey and northern Iraq, grown for its large, heavily veined flowers in spring. It needs well-drained soil, full sun and a dry summer dormancy to thrive.
Iris gatesii is a species in the genus Iris, it is also in the subgenus Iris and in the section Oncocyclus. It is a rhizomatous perennial, from the mountains of Turkey and Iraq. It has long, narrow, grey-green or glaucous leaves. The strong, sturdy stem supports a single large flower in spring, between April and June. The large flowers are very variable in colouring, ranging from a pale greenish, grey, white, or creamy-yellow background colour, which is then covered with many purplish-brown, purple, or nearly black, spots, dots, short broken lines, or veining. They have a brownish purple or purple beard, over a dark signal patch. It can be cultivated as an ornamental plant in temperate regions, if it does not get too wet during summer.
Due to its range being much farther north than most Oncocyclus irises, it is more hardy in cultivation, than others.
It is hardy to between USDA Zone 8 to 9.
Like many other irises, most parts of the plant are poisonous (rhizome and leaves), and if mistakenly ingested can cause stomach pains and vomiting. Also, handling the plant may cause skin irritation or an allergic reaction.
