Homonym: four-leaf clover (Luck)
A four-leaf clover is a rare variation of the common three-leaf clover, or white clover (Trifolium repens). Each leaf is said to represent a different quality: faith, hope, love, and luck. Finding one is considered a good omen, as they are estimated to occur in about 1 in 5,000 clovers.
The four-leaf clover has become a symbol of good fortune in various cultures. Many people search for them in grassy areas, especially during spring and summer. They are often associated with St. Patrick's Day and Irish folklore, where they are believed to ward off evil spirits.
