Four-Leaf Clover Facts to Know for St. Patrick's Day

Why is the four-leaf clover a universal symbol of good luck? Catch up on these fun facts about the unusual green plant associated with St. Patrick's Day.

Today, looking for four-leaf clovers is a St. Patrick's Day tradition, but have you ever wondered why they're considered lucky—or how they came to be associated with the holiday? It turns out, the story behind the clover dates back hundreds of years before we began drinking green beer and pinching friends who didn't wear green on the holiday.

The four-leaf clover (officially known as Oxalis deppei) is a small plant with four distinct leaves. It's a rare variation of the common three-leaf clover, and because your chances of finding one with four leaves is about 1 in 10,000, they're considered lucky.

Four-leaf clovers have been around for ages, and their supposed lucky powers are talked about in centuries-old legends. In the early days of Ireland, Celtic priests known as Druids carried three-leaf clovers, or shamrocks, in the belief that with their help, they could see evil spirits approaching and be able to escape. Four-leaf clovers, then, were Celtic charms, offering magical protection and warding off bad luck. Children in the Middle Ages believed they might be able to see fairies if they carried a four-leaf clover.

The Difference Between Four-Leaf Clovers and Shamrocks

Both shamrocks and four-leaf clovers are associated with St. Patrick's Day, and they're commonly confused as the same thing. A shamrock is a clover with three leaves, but the four-leaf clover is considered lucky due to its rarity. Shamrocks are still an important part of the holiday, and there's a deep religious significance that explains why we celebrate St. Patrick's Day with shamrocks.

Now that you know the difference, catch up on these fun facts about four-leaf clovers before you start making a St. Patrick's Day dessert.
