Its native range extends across the Mediterranean Region from Portugal to Turkey.[3][4] The species is cultivated as an ornamental and has become naturalized in many areas, including Pakistan, Australia, New Zealand, and in southern and western parts of the United States. It is classed as an invasive species in parts of the U.S.,[5] and is found primarily in the U.S. states of California, Texas, Louisiana, and Florida.[6][7]

Allium neapolitanum produces round bulbs up to 2 cm (0.79 in) across. The scape is up to 25 cm (9.8 in) tall, round in cross-section but sometimes with wings toward the bottom. The inflorescence is an umbel of up to 25 white flowers with yellow anthers.[6][7][8][9]

Allium neapolitanum seems to have beta-adrenergic antagonist properties.[10]
