This a picture of an actual shamrock plant. According to tradition the shamrock was used by St. Patrick to explain the three persons in the Trinity. In Ireland a bunch of this plant is worn by many people in the lapels of their jackets on 17th March St. Patrick's Day.
I'm using this picture to illustrate how tiny the individual leaves of the shamrock are.The picture is really large but the width of the leaf is only 2 centimeters.
