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 western Asia, but it is cultivated in many other places and has become naturalized in many countries. 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. Allium ampeloprasum has been differentiated into three cultivated vegetables, namely leek, elephant garlic and kurrat.
