The Shamrock is a small clover and was an important symbol to the ancient Irish druids because its three heart-shaped leaves represent the triad. The national flower of Ireland.
- Legends belived that St. Patrick ripped the shamrock off the Irish soil to demonstrate the meaning of the Trinity Father, Son, and Holy Spirit.
- The Celts believed that everything necessary in the world comes in threes.
- Like the three ages of man, the moon phases, and the three dominions of earth, sky, and sea.
