Why is the four-leaf clover a universal symbol for good luck? Learn the history and more facts about the unusual green plant associated with St. Patrick's Day.
Today, four-leaf clovers are 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. Children in the Middle Ages believed if they carried a four-leaf clover, they would be able to see fairies, and the first literary reference to suggest their good fortune was made in 1620 by Sir John Melton.
