How do I know I have a true four leaf clover? Most all medium to large size white four leaf clover have three leafs that are the same size, the fourth leaf is smaller. Retail items show that all four leafs are the same. We see stickers, embroidered patches and retail items that have a four leafs showing all the leafs the same size. This must make a few think that they all look this way. White clover, which are the clover shown for sale in my store have 1 leaf that is smaller. But... I have found a few four leafs where there are three leafs are the same size leafs and one larger. That's nature for you. I do not know what type of clover they are putting in jewelery, all the leafs looks the same size, maybe as the clover grows, the four leaf does not. White clover is a common clover grown in the USA.
