Trivia

 * The Clover is called "54 Leaf Clover" in the achievements screen.
 * It is a reference to the Guinness world record for the most leaves on a single clover stem. 4 leaf clover is considered to bring good luck, so 56 leaves must be even luckier.

Bugs
As stated above the article, this item actually gives 1% chance of giving an item (additive stacking), not 4%.
