The shamrock is a symbol of Ireland. It is a three-leafed old white clover. The shamrock was traditionally used for its medical properties and was a popular motif in Victorian times. It is also a common way to represent St. Patrick's Day. The term shamrock derives from the Irish word, seamrog, which translates to 'little clover'. The three leaves of the shamrock are said to represent the the three persons of the Trinity.Shamrocks should not be confused with four leaf clovers regarded as lucky charms. Four leaf clovers were elevated to the status of lucky charms by the Druids (Celtic priests). The four leaf clovers are sometimes said to stand for faith, hope, love and luck. It is estimated that, on average, there are 10,000 three leaf clovers for every instance of a true four leaf clover.
