Saint Patrick's Day, or the Day of the Festival of Patrick, is a cultural and religious celebration held on the 17th of March, the traditional death date of Saint Patrick (c. AD 385–461), the foremost patron saint of Ireland.1. We love St. Patrick's Day, because lets face it, it's also a wonderful excuse to party! Corned beef & cabbage and green beer are all good, but what about dessert? That's where shamrock-shaped maple candies come in. And when you want to wish someone afar Happy St. Patrick's Day, what better way to do so then with a box of shamrock maple sugar candy from the Green Mountain State.
