Did you know the term “shamrock” comes from the Irish Gaelic word, seamrog, which means “little clover?” While there is no official shamrock plant, the word shamrock can be used to describe a number of varieties of three-leafed clovers. According to Irish legend, St. Patrick demonstrated the principle of the Trinity using a shamrock, pointing to its three leaflets united by a common stalk. Thus, while a four-leaf clover is considered a “lucky find” due to its rarity, it is not a shamrock, which always has only three leaves.
