Four Leaf Clover is not a Shamrock

The Four leaf clover has become one of the most well known lucky symbols around the world and across many very different cultures.

In Ireland, the clover has long been considered lucky. The Shamrock or three leaf clover is mainly an Irish Christian symbol of the Holy Trinity - The Father, The Son, and The Holy Spirit. They also believe that when St. Patrick was trying to teach the Irish people and others about Christianity, he used the three-leaf to help then understand the concept of the Holy Trinity.

It has been estimated that there are approximately 10,000 three-leaf clovers for every four-leaf clover. The rare four-leaf clover is viewed as particularly powerful and magical. According to the legends of western culture, each of the four leafs represent one theme. The first leaf is for hope, the second is for faith, the third is for love, and the fourth is for luck.
