When I was young, one of my mother’s close friends had a garden tucked with all sorts of interesting things, such as dill, horseradish, and strawflowers. But my favorite plant was her Lunaria because it yielded bouquets of silvery, translucent disks. Though named the “money plant” or the “silver dollar plant”, to me the seedpods looked like bundles of tiny moons tethered to the earth by slender but tenacious stems. The Latin name ‘Lunaria’ means “moonlike.”
Last year, my 7-year-old son discovered “money plant” seeds at the nursery and was instantly attracted to the idea of growing money. Lunaria is easy to grow, though we actually forgot we had planted it until this summer when the distinctive pods emerged. The Lunaria plant itself looks unremarkable in the garden, with broad, floppy leaves and clusters of shy, purple flowers. When the seedpods sprouted, they looked like flattened sugar peas. Then they turned a dirty brown that definitely looked unappealing (in fact, when I harvested a Lunariaplant this summer and left it on a patio table to dry, my husband tossed it on the compost pile). But peel back the dry husk and a shiny, papery moon reveals itself, ready to last for years in a dried flower arrangement or on its own.
My son, though, was a little disappointed he couldn’t spend the “money” we raised in our garden.
Lunaria, a member of the mustard (Brassicaceae) family, originated in Europe and migrated to America with early settlers. The plants are biennials, growing one year and flowering the next. The seeds sprout easily, making them a nuisance in tidy gardens. They bloom spring through early summer. In Zone 5, where I garden, the pods were dry and ready for cutting by early August.
How to Grow:
Direct sow Lunaria seeds in the spring and cover lightly with soil, then water.
Lunaria thrives in most soil types (even my clay!), prefer sunny sites but deal with partial sun. Fertilize once a year, if you’re into that sort of thing, and water if they seem droopy (but remember that Lunaria dislike consistently soggy soils). After the seedpods have turned brown, they are ready for harvesting. If not quite ready, you can hang upside down and dry for an additional week or two. Then simply peel off the brown layers on each side of the pearly “coin” and your Lunaria are ready for display.
