Since I had nothing better to do this (early) morning I did a little research on “shamrocks”, and found out a couple of interesting things. It seems that there is no one “shamrock plant’. Any of several three leaf plants can be correctly called shamrocks, including (the most popular) white clover (
Trifolium repen), red clover, sorrels, and black medock. So if it looks like a shamrock it is OK to call it a shamrock. Now a four leaf clover (lucky) is most likely to be a white clover plant with an extra leaf, it cannot be a shamrock, because by definition a shamrock has three leaves. I just love this trivia stuff. Guess it’s time for bed.
