Iris glaucescens

About

Iris glaucescens is a plant species in the genus Iris and subgenus Iris. It is a rhizomatous perennial, found in Russia, Kazakhstan, Mongolia and China. It has blue-grey sickle-shaped leaves, slender stem, and spring flowers in blue-violet, pale violet, lilac-purple, to deep purple, to light bluish, and almost white shades. It is rarely cultivated as an ornamental plant in temperate regions. It was merged with another similar iris in the region, and became a synonym of Iris scariosa, before being divided into two separate species again, although some sources still call it a synonym of Iris scariosa.
