Tephrosia virginiana (L.) Pers.
Goat's rue, Virginia tephrosia, Devil's shoestring
Fabaceae (Pea Family)
Synonym(s): Cracca latidens, Cracca virginiana, Tephrosia latidens, Tephrosia virginiana var. glabra, Tephrosia virginiana var. holosericea
USDA Symbol: tevi
The flowers of goat’s-rue resemble bi-colored sweet peas. Lower petals are pink; upper petals are pale yellow. Pinnately compound leaves have 8-15 pairs of leaflets. Stems and leaves are covered with soft, white hairs giving the 1-2 ft. perennial a silvery appearance. Mature plants form attractive mounds. Bicolored, pea-like flowers, with pink wings and a yellow standard, crowded into clusters atop a hairy stem.
A distinctively silvery plant, Goats Rue has long stringy roots, to which the common name Devils Shoestrings refers. It was at one time fed to goats to increase their milk production, but since it contains rotenone (now used as an insecticide and fish poison), this practice has been discontinued. In the South, several white-flowering species occur (T. spicata, T. chrysophylla, etc.) with fewer flowers per cluster on the tips of long stalks. These flowers eventually turn pink, and the foliage is often distinctive because of brownish or golden hairs.
