Iris korolkowii, the Redvein Iris, is a rhizomatous perennial from mountains of Central Asia, grown for its grey-green sword-shaped leaves and white to pale purple flowers veined with dark markings. The key to growing it is full sun, very well-drained soil, and a dry, warm summer rest.
Iris korolkowii is a plant species in the genus Iris. It is also in the subgenus Iris and in the section Regelia. It is a rhizomatous perennial, from the mountains of Tien Shan, Pamir and Altai, in Afghanistan and Turkestan (now part of Uzbekistan). It is commonly known as the Redvein Iris. It has long, sword-shaped grey-green leaves, slender stem, and 2 to 3 white, cream, pale green or light purple flowers which are veined with maroon, chocolate brown or dark purple. It is cultivated as an ornamental plant in temperate regions.
It is hardy to USDA Zone 5, although could be possibly between Zone 6 to Zone 9. It is hardy to European Zone H4.
It prefers to grow in well-drained soils, such as gritty and sandy but stiff loamy soil (suggested by Sir Michael Foster), but can tolerate all garden soil types.
Iris korolkowii is native to temperate areas of central Asia.
