Senna hebecarpa, American Wild Senna, Howard County, MD
American Wild Senna. A lovely, and slightly exotic wildflower found in Maryland, Howard County by Helen Lowe Metzman. I don't often see bees on this plant and from the structure of the plant it would seem to be oriented to pollination by bumble bees.
