- Description
-
The common names tell its history. Goat's Rue was fed to goats to increase milk production. It is no longer used as a feed for goats due to it containing rotenone which is now used as a pesticide. It is also used as fish poison, which is produced by pounding the roots. Another common name, Devil's Shoestring, refers to its long stringy roots.
This member of the pea family has upright to sprawling stems. It is native to dry, open woods, and best grown from seed as its deep root system makes dividing and transplanting rarely successful.
The flowers resemble bi-colored sweet pea, lemon-yellow to rose. Its upper petals and pale yellow, while the lower petals are pink. It begins to bloom in the spring and continues into the summer. After the flowers have bloomed, seed pods are formed. They can reach lengths of 3".
Growing this plant will add nitrogen to your soil.
