1. The odds of finding a four-leaf clover are 1 in 10,000

This is one of the reasons we say it's the luck o' the Irish.

3. Four-leaf clovers aren't shamrocks

I know. Mind. Blown.

Shamrocks are the three-leaf version, not the lucky four-leaf we hear so much about.

Of course, several pints of ale could probably help with this, too...

Some traditions say four-leaf clovers are only lucky if you keep them hidden from other people, but other traditions say your fortune will double if you give your clover to someone else.

Four-leaf clovers are said to help you find your true love. Some people even put clovers in their shoes to lead their feet to their soulmate.

13. Clovers can be unlucky, too
