The Q&A Archives: Silver Dollar Plants

Question: I have never seen silver dollar plants themselves-- just the flowers. A friend gave me seeds which I planted last year and had a very tiny plant. This year it has taken off considerably! It is loaded with small purple flowers. Is this what they look like before turning into the silver dollar type?

Answer: Yes! Those purple flowers you see will develop into the seed pods. The decorative white "silver dollars" are actually the center partition of the seed pods. Lunaria annua is actually a biennial. The plant produces only foliage the first season, then flowers the second. After flowering the plant dies. However, Lunaria readily self-sows, so you should get more seedlings next year. (Unfortunately, these seedlings won't flower until the following year.) Lunaria, also called "money plant" and "Honesty" will grow in either sun or shade, but prefers partial shade and a moderately fertile, well drained soil.
