Allium rotundum, common name round-headed leek or purple-flowered garlic, is a Eurasian and North African species of wild onion. Its native range extends from Spain and Morocco to Iran and European Russia.^[2] It is sparingly naturalized in parts of the United States (Michigan and Iowa).^[3] The species grows in disturbed habitats such as roadsides, cultivated fields, etc.^{[4][5][6][7][8][9]}

Allium rotundum produces large clumps of as many as 50 egg-shaped bulbs, each up to 1.5 cm long. Leaves are up to 40 cm long. Scapes are up to 90 cm tall. Umbels look round from a distance, and can contain as many as 200 flowers. Flowers are bell-shaped, up to 7 mm across; tepals purple, sometimes with white margins; anthers yellow or purple; pollen yellow or white.^[4][10][11]
