Bidens cernua, Nodding Beggartick backside flower, Howard County, Md

Beggar's-Ticks of the Nodding variety. Showy, and, at times, filling ditches in low areas of Maryland. One of the native plants that seems to be happy with disturbed environments and they come with barbed seeds that stick to the coats of animals and the coats of people with equal vigor. Lots of yellow in the fall...beautiful. Specimens and pictures by Helen Lowe Metzman.
