Silky bush clover is a native of China, Korea, Japan, Formosa, and Himalayas. It was introduced to North America in the 1800s, originally to reclaim rapidly eroding soils. It is now widespread and, in most areas, invasive.
Identification: Plants are 3-6' (91-182 cm) in height, with one or several upright-reaching sericeous stems that have stiff, flattened bristles. These look like woody perennials, but they are annuals. Leaves are alternate, closely spaced, covered with dense, flattened hairs, in clusters of three, obovate, narrowly obovate, or oblanceolate, each ⅛-⅞" (5-25 mm) long, with wedge-shaped leaf bases and rounded ends with a sharp, hairlike tip. They are attached via very short petioles. Flowers are cream-colored, bilaterally symmetrical, with purple throats, appearing from July to September. Fruits are flat to round pods with a single seed, ¹/₁₆-³/₁₆" (3-5 mm) long, with hairs flattened against the fruit.
