Allium amethystinum

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]
