Region of origin:
Region of cultivation:
- Cultivation and Breeding:
The leek probably arose from the wild type Allium ampeloprasum, which is a native of South Europe and Asia. The history of its cultivation essentially corresponds to that of the onion. It can be distinguished from the onion by the absence of a pronounced "onion" bulb, the strong elongation of the under-leaves and also the flat unrolled upper-leaves. There are short-lived summer and frost resistant winter varieties.
- Breeding aims:
Stable, high yielding varieties with uniform length, white shafts and erect leaves are required. Winter varieties must exhibit frost hardiness.
