leek: see onion.

Hardy, vigorous, biennial plant (Allium porrum) of the lily family, native to the eastern Mediterranean and the Middle East. It has a mild, sweet, onionlike flavour. In Europe it is widely used in soups and stews and is cooked whole as a vegetable. It became the national emblem of Wales following an ancient victory by an army of Welshmen who wore leeks as a distinguishing sign. The long, narrow leaves and nearly cylindrical bulb of the first season are replaced in the second season by a tall solid stalk bearing leaves and a large umbel with many flowers.
