"On Saint David's Day,
Put some oats and barley in your clay."

This day commemorates the patron saint of Wales, St David, who was born in the sixth century at Henfynw, Cardigan. His symbol is the leek, which is said to have protected him in combat and was worn by his countrymen to distinguish them from their Saxon enemies during battle. In honor of St David, plant a bulb of aromatic leek as soon as the ground can be worked. (from the Old Farmer's Almanac)
