Allium amethystinum is a plant species native to Italy, Greece, Turkey, Sicily, Crete, Malta, Albania, Bulgaria, and the former Yugoslavia, and cultivated elsewhere as an ornamental.[2] It is one of several species that horticulturalists refer to as "drumstick onions" because of the tight spherical "knob" of flowers at the top, resembling a drumstick.[3][4]

Allium amethystinum has a single bulb. Leaves are tubular, withering before flowering time. Flowers are reddish-purple, the tepals barely opening at flowering time, remaining wrapped around the ovary and filaments so that only the anthers and stigma are exposed.[5][6]
