The Girl Scout symbol is the TREFOIL, which is a three-leaf clover. The TREFOIL has been used as a symbol of the Girl Scouts since its founding in 1912. It is a representation of the three-fold promise that Girl Scouts make to serve God, their country, and to help people at all times. The TREFOIL is also used to represent the three parts of the Girl Scout Law: to be honest and fair, to be friendly and helpful, and to be considerate and caring.
