Crownvetch is a low-growing, herbaceous vine that usually forms thickets up to 3 ft. (0.9 m) in height. The leaves are pinnately compound with 9 to 25 pairs of leaflets and a terminal leaflet. Leaflets are 0.75 in. (1.9 cm) long. Flowering occurs in the summer. The pea-like, fragrant flowers are white to pink to purple and resemble a large clover flower. Crownvetch reproduces and spreads rapidly by rhizomes as well as seeds. It forms dense thickets in open, disturbed areas such as fields and roadsides. Once established it is difficult to remove. Crownvetch is native to Europe, Asia and Africa. It was first introduced into North America around the 1950s and has been widely planted for erosion control. |
