Don't be fooled — the Shamrock is actually a type of Clover! It always has exactly three leaflets, each representing the Holy Trinity. Those lucky 4-leaf clovers? Just a rare mutation. And those heart-shaped "shamrocks" in stores? They're likely wood sorrel — not even in the clover family! The word "shamrock" simply means "little clover" in Gaelic, which explains the centuries of confusion.
