Iris stolonifera is a rhizomatous perennial iris from the mountains of Central Asia, grown for its scented blue-grey to white and purple flowers in late spring. It spreads through red-skinned stolons, so it forms colonies over time.
Iris stolonifera 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 Turkestan, between Tajikistan, Uzbekistan and Afghanistan. It has red-skinned stolon roots and rhizomes, glaucous, long, blue-grey leaves, and bi-coloured flowers, in various shades from milky white, to blue, purple, pale lilac, lavender, and brown. It normally has blue to yellow beards on all the petals.
It is very cold hardy, to USDA Zone 5, or between Zone 5 to Zone 8. It is also hardy in Europe to Zone H3. In very cold areas, such as Russia, the plant may die out after 2 or 3 years.
It prefers to grow in well-drained soils, which are rich in humus.
Iris stolonifera is native to temperate areas of central Asia.
