The four leaves themselves were said to represent faith, hope, love, and success.

Anything Irish

Perhaps no other country or culture is associated with luck as that of Ireland. “The luck of the Irish” has become a regular part of the English language and many of the lucky charms on this list are also associated with the country such as shamrocks, rainbows, and leprechauns.
