Sub-category: Pea family
Grows to about 3 feet tall and normally erect, although it sometimes sprawls along the ground. The green central stem has fine white hairs, sometimes turning brown in response to drought. There are usually a few flowering side stems in the upper half of a large mature plant. The compound leaves consist of three leaflets that are greyish green. Each compound leaf has a short petiole with a pair of small deciduous sheaths at its base. The leaflets are 2 to 3.5 inches long and less than half as wide. They are oblong or lanceolate in overall shape, but rounded at the tips rather than pointed. Their undersides have fine hooked hairs that cling to clothing or the fur of passing animals. Numerous pink flowers in an elongated panicle occur at the end of one or more of the upper stems.
Found in woods, prairies, and disturbed habitat, such as roadsides. It is cultivated as an ornamental plant so it may be found in flower or butterfly gardens.
