The shamrock is a type of clover with three leaves. The most well-known meanings were imparted to the shamrock by St. Patrick, who compared the plant’s tri-part leaves to the Holy Trinity: Father, Son and Host Spirit. Occasionally shamrocks are found with four leaves. These are rare and considered to be very lucky for the finder.
A common saying associated with the shamrock and the clover family is “to be in clover” or to live a carefree life of ease and prosperity. Shamrocks are often associated with leprechauns, a generally harmless type of fairy said to live in seclusion and protect hordes of gold. However, if a human should attempt to capture a leprechaun to learn the whereabouts of his gold, the leprechaun may turn mischievous or practice hypnotism or trickery to evade or confuse his pursuer. The shamrock can undo the malevolent magic of a leprechaun.
