The Shamrock
The shamrock, a small clover which is now the national flower of Ireland, was an important symbol to the ancient Irish Druids as a plant naturally displaying the triad with its three heart-shaped leaves.
The Celts believed that everything important in the world came in threes; the three dominions of earth, sky and sea, the three ages of man, and phases of the moon; so a plant with three leaves would have been held in high regard.
