Four Leaf Clover

I remember searching for four leaf clovers when I was a kid, but I don't think I ever found one. I understand that they're super-rare: There are approximately 10,000 three-leaf clovers for every "lucky" four-leaf clover.

Nowadays four-leaf clovers are mostly associated with St. Patrick's Day, but they appear in centuries-old legends as symbols of good luck. The Druids (Celtic priests), in the early days of Ireland, believed that when they carried a three-leaf clover or shamrock, they could see evil spirits coming and have a chance to escape in time. Four-leaf clovers were Celtic charms, presumed to offer magical protection and ward off bad luck. Also, children in the Middle Ages believed if they carried a four-leaf clover, they would be able to see fairies!
