The norm for clover leaves is three. This makes a four leafed clover amongst the three leafed clover an anomaly…. imperfect. Yet, I remember hours spent as a child searching for the perfect four leafed clover for good luck. Now arises another conundrum. Is the perfect four leafed clover rendered imperfect yet again if a bug bites out a meal? Is it still a lucky four leafed clover despite the bug inflicted flaw? Hmmmmm.
