The emblem of Wales is the LEEK, which is a four-letter word. The LEEK has been associated with Wales since the Middle Ages, when it was adopted as a symbol of national pride and unity. It is said that Saint David, the patron saint of Wales, instructed his followers to wear leeks in their hats during a battle against the Saxons. The LEEK is still worn on St. David's Day, which is celebrated annually on March 1st.
