Honesty

 I remember this flower being called the Money Plant or  Silver Dollars. By the fall, the seed pod has formed and it is the size of a silver dollar. It is a flat, round, translucent, and papery seed pod. Its latin name is Lunaria bienni.... you will notice that the latin word for moon is in the name... Luna. The seed pod does look like a silvery moon once it has shed its outer seed case, which is rather a dull brown. As children we would collect these Silver Dollars and then count them like little misers to see who was the richest.
