Solution (By Examveda Team)

Allium porrum is Leek.
The leek is a vegetable, a cultivar of Allium ampeloprasum, the broadleaf wild leek. The edible part of the plant is a bundle of leaf sheaths that is sometimes erroneously called a stem or stalk.
Leeks are easy to grow from seed and tolerate standing in the field for an extended harvest, which takes place up to 6 months from planting.
