Allium paniculatum, common name Mediterranean onion, is a Eurasian species of wild onion with a range extending from Portugal to Kazakhstan.[3] It is widely cultivated and is now naturalized in several places outside its native range.[4]

Description[edit]

Allium paniculatum produces several egg-shaped bulbs, each up to 1.5 cm across. No rhizomes. Leaves are tubular and hollow, up to 35 cm long. Scape is round in cross-section, solid, up to 75 cm tall. Inflorescence is (despite the name of the species) an umbel with as many as 100 flowers. Flowers are bell-shaped, about 6 mm across; tepals white to lilac; pollen and anthers yellow.[5][6]

Distribution[edit]

Allium paniculatum has been reported from every European country bordering on the Black and Mediterranean Seas, including the islands of Corsica, Sardinia, Sicily and Crete. It is also considered native in Portugal, the Czech Republic, Hungary, western Siberia, Kazakhstan, Armenia, Georgia, Azerbaijan, Iran, Iraq, Lebanon, Syria, Israel, and Palestine. It has become naturalized in California, New York State, Azores, Madeira, Canary Islands, and South Australia.[7][8]

The species has been collected in the vicinity of San Francisco Bay in California, as well as isolated locales in Essex County in northeastern New York State. This is of concern because the species has the potential to become a noxious weed. It tends to grow in disturbed sites such as roadsides, cultivate fields, etc.[5][7]
