In the old days, this spring blooming biennial was called Honesty, and then became Silver Dollar Plant. The second season it sends up 2′ stalks bearing clusters of lavender (this form tends more towards blue, which isn’t always easy to capture on images) flowers that area favored by early foraging bees. As the flowers fade curious seed pods. When mature you can pull back the papery coating to reveal silver ovals that make for excellent dried flower arrangement material.
