Iris perrieri is a plant species in the genus Iris; it is also in the subgenus Iris. It is a rhizomatous perennial, from the Savoy Alps in southern France and recently in Italy. It has green, deeply ribbed, sickle shaped leaves, a slender stem with a branch (from the middle), 1–3 scented flowers that are violet or purple, with a white or pale blue beard. It is rarely cultivated as an ornamental plant in temperate regions, due to its rarity in the wild. It was once thought to be a form of Iris aphylla, before cell (chromosome) analysis determined it to be a separate species.
