The luck of the Irish is upon you ready for St.Patrick's Day celebrations on March 17th to honor the patron saint of Ireland. The symbol of that Emerald Isle, the lush green clover, called a shamrock, with its characteristic heart-shaped leaves is shown here in the colors of the Irish flag--green, white and orange--and they are scattered in rows on a deeper emerald green background. Maybe you will be lucky enough to find a 4-leaf clover this St. Paddy's Day!
