There are about 550 species worldwide, most of them occurring in the northern hemisphere. Allium dregeanum is the only species thought to be native to southern Africa although there is some doubt that it originates here. Allium triquetrum (Three-cornered leek) is naturalised in the region and an additional 12 species are cultivated, including leek, onion, shallot, chives and garlic.

Allium sativum (Garlic)

Garlic is grown as a vegetable and is also used for medicinal purposes because of its natural antibacterial and antifungal properties. Allium sativum is a domesticated species, thought to have originated from Allium longicuspis which is native to Central Asia. Evidence from Egyptian tombs shows that domestication of garlic goes back to at least 3200 BC. Modern garlic varieties are propagated vegetatively because seeds are infertile.
