Goats Rue is a silver-leaf plant. Its roots are long and stringy, to which one of its names refers, Shoestring. It was once fed to goats to increase milk production but when it was discovered that the plant contains an insecticide and fish poison (rotenone) the practice was discontinued. There is a variety on the Coastal Plain that has only white flowers but that species is outside this region.
