Explanation
A shamrock is a three-leafed green clover that's used to symbolize Ireland. Go all out for St. Patrick's Day this year — decorate your whole house with shamrocks! A clover must have exactly three leaves to be a shamrock, and some people believe only certain clover varieties qualify. Since at least 1675, Catholics have associated the shamrock with Saint Patrick, who famously used it to represent the Holy Trinity. It wasn't until the 18th century that it shifted from representing Ireland's patron saint to Ireland itself. The shamrock even shows up on some British coins, alongside the English rose and Scottish thistle.
