Annual Honesty (Lunaria annua) is a tall (height about 1 m), hairy-stemmed biennial plant found throughout Europe, North America, and parts of Asia. It has large, pointed oval leaves with marked serrations. The common name "Honesty" arose in the 16th century, and it may be due to the translucent seed-pods which are like flattened pea-pods and borne on the plant through winter. In South-East Asia and elsewhere, it is called the Money Plant, because its seed pods have the appearance of silver coins. In the United States it may also be known as "Silver Dollars," also because of the seed pods.
