Iris stolonifera is a species in the genus Iris; it is also in the subgenus of Iris, and in the Regelia section. 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 has a rhizome, that in the spring, sends out thin, and long, (up to 20 cm (8 in) long,) secondary roots (or stolons), which have a red skin. At the end of each stolon, it forms a new rhizome, creating widespread colonies of plants. Other 'Regelia section' irises also have stolons. Also Iris japonica, Iris prismatica and Iris henryi produce stolons.
It has dark blue-green, or glaucous leaves. They are sword-shaped, and 30–60 cm (12–24 in) long, and 0.8 cm to 2 cm wide. They are prominently veined, and semi-evergreen, disappearing after summer, after the blooming period is over.

The stems hold 2-3 terminal (top of stem) flowers, blooming in late spring, between April and June, or May, or between May and June.
The scented, flowers are 7–8 cm (3–3 in) in diameter.
They are variable in colour, normally bi-coloured, ranging from milky white, to blue, to purple, (or pale lilac, or lavender,) and brown. They normally have a blue (or pale lilac,) centre with a brown, or reddish-bronze, or yellow margin.
