Also called “seamroy” by the Celts, the shamrock is another important part of the Irish people’s commemoration of St. Patrick’s Day. This sacred plant that grows in ancient Ireland is believed to represent the rebirth of spring and emerging Irish nationalism. It symbolizes their pride and heritage and is worn by the Irish community in their hats every 17th of March of every year. They believe that by wearing this three leafed grass, they are able to set forth to them the Mystery of the Holy Trinity. They also perform a ritual called “drowning of the shamrock,” wherein they put the worn shamrock in a glass of grog or punch, drink the punch and pick out the shamrock from the bottom of the glass and throw it over their left shoulders.
