Allium ampeloprasum is a member of the onion genus Allium . The wild plant is commonly known as wild leek or broadleaf wild leek. Its native range includes southern Europe, southwestern Asia and North Africa, but it has been cultivated and naturalized in many other countries.
Allium ampeloprasum has been differentiated into five cultivated vegetables: leek, elephant garlic, pearl onion, kurrat, and Persian leek.
Wild populations produce bulbs up to 3 centimetres (1+1⁄4 inches) across. Scapes are round in cross-section, each up to 180 cm (71 in) tall, bearing an umbel of as many as 500 flowers. Flowers are urn-shaped, up to 6 millimetres (1⁄4 inch) across; tepals white, pink or red; anthers yellow or purple; pollen yellow. [2] [3]
The plant's native range is southern Europe to southwestern Asia and North Africa, [4] including all countries bordering the Black, Adriatic, and Mediterranean Seas from Portugal to Egypt to Romania. In Russia and Ukraine, it is considered invasive except in Crimea, where it is native. It is also native to Ethiopia, Uzbekistan, Iran and Iraq.
It is considered naturalized in the United Kingdom, Ireland, the Czech Republic, the Baltic States, Belarus, the Azores, Madeira, the Canary Islands, Armenia, Azerbaijan, Afghanistan, China, Australia (all states except Queensland and Tasmania), Mexico, the Dominican Republic, Puerto Rico, Haiti, the United States (southeastern region plus California, New York State, Ohio and Illinois), Galápagos, and Argentina. [1] [2] [5] [6] [7]
The species may have been introduced to Britain by prehistoric people, where its habitat consists of rocky places near the coast in south-west England and Wales. [8] [9]
The plant is protected by law in Israel [10] as well as York County, Virginia, where it is commonly known as the "Yorktown onion". [11]
Allium ampeloprasum is the source of several vegetables, most notably:
Some sources (especially archeological ones) refer to each of these as a separate species, [14] but they are now united as A. ampeloprasum.
The plant is mentioned as shaḥm el-arḍ in an 11th-century Mishnah commentary. [15]
The more robust varieties grown for their thick 'pseudostem' (A. porrum L. senu stricto) and the slender leafy forms (sometimes referred to as A. kurrat Schweinf.), are all closely related to, and inter-fertile with, the wild and weedy tetraploid forms of wild Allium ampeloprasum L., which is widely distributed in the Mediterranean basin.
