Leeks are one of the national symbols of Wales — Welsh soldiers wore leeks in their caps during a 7th century battle against the Saxons to distinguish themselves from the enemy. The word leek comes from the Old English word leac meaning plant. Leeks have been cultivated in Egypt for over 4000 years and appear in Egyptian wall paintings.
