Garlic
Taxonomy

Identification of the wild progenitor of common garlic is difficult due to the sterility of its many cultivars, which limits the ability to cross test with wild relatives. Genetically and morphologically, garlic is most similar to the wild species Allium longicuspis, which grows in central and southwestern Asia. However, because A. longicuspis is also mostly sterile, it is doubtful that it is the ancestor of A. sativum. Other candidates that have been suggested include A. tuncelianum, A. macrochaetum, and A. truncatum, all of which are native to the Middle East.

Allium sativum grows in the wild in areas where it has become naturalized. The "wild garlic", "crow garlic", and " field garlic " of Britain are members of the species A. ursinum, A. vineale, and A. oleraceum, respectively. In North America, A. vineale (known as "wild garlic" or "crow garlic") and Allium canadense (known as "meadow garlic", "wild garlic", or "wild onion") are common weeds in fields. So-called elephant garlic is actually a wild leek (A. ampeloprasum) and not a true garlic. Single clove garlic (also called pearl or solo garlic) originated in the Yunnan province of China.
