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 is southern Europe to southwestern Asia and North Africa,[2] but it is cultivated in many other places and has become naturalized in many countries.
Allium ampeloprasum has been differentiated into five cultivated vegetables, namely leek, elephant garlic, pearl onion, kurrat, and Persian leek. Some sources (especially archeological ones) refer to each of these as a separate species,.[3] but they are all united in A. ampeloprasum now.

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.
