What is a Four Leaf Clover?
A four leaf clover refers to an aberration of a three leaf clover plant, the Trifolium repens or “white clover.” The white clover is a deep green flowering vine with white blossoms. It is the original shamrock plant of Ireland and the unofficial state symbol. The shamrock already has powerful associations, and its occasional production of an extra leaf makes the rare four leaf clover especially lucky.
