Sticking with a flower/plant type theme this week for my Rainbow Challenge - a green clover plant in honor of St. Patty's Day which is on Sunday.
"The three leaves of a shamrock are said to stand for faith, hope and love. A fourth leaf is where luck comes from. The four-leafed clover, or “lucky clover”, is an uncommon variation of the three-leafed clover, and widely considered to be a symbol of good luck."
