Clover or Shamrock

CLOVER OR SHAMROCK -  Symbolic shamrock meaning got its most popular reputation in Ireland around the fifth century. During this time Saint Patrick was going about the business of introducing and establishing Christianity among the people.  St. Patrick must have understood this as legend indicates he utilized the three leafed clover as an illustration of the Christian Holy Trinity (Father, Son & Holy Spirit).  St. Patrick tuned into the natural triad of the shamrock, and as clover was so prevalent on the Irish hillsides, the shamrock seemed a natural, logical visual-aid for making his point. Patrick was passionate about sharing his faith with the people of Ireland, and cleverly found associated each leaf of the clover with an aspect of the Holy Trinity.  The three leaves may also be symbolic of the three theological virtues found in first Corinthians 13:13. (Faith, Love and Hope)

Also used to signify Irish heritage.
