Shamrocks are NOT uniquely Irish -- 2012 National Geographic online posting

www.nationalgeographic.com/

         Today, St. Patrick's Day revelers wear a shamrock. Trifolium dubium, the wild-growing, three-leaf clover that some botanists consider the official shamrock, is an annual plant that germinates in the spring.
       Other three-leaf clovers, such as the perennials Trifolium repens and Medicago lupulina, are "bogus shamrocks," according to the Irish Times.
        John Parnell, a botanist at Trinity College Dublin, said that Trifolium dubium is the most commonly used shamrock today, which lends credence to the claims of authenticity.
       However, he added, the custom of wearing a shamrock dates back to the 17th and 18th centuries, and "I know of no evidence to say what people then used. I think the argument on authenticity is purely academic—basically I'd guess they used anything cloverlike then."
       What's more, botanists say there's nothing uniquely Irish about shamrocks. Most clover species can be found throughout Europe.
