The very small, Clover-like leaves and bright yellow, butterfly-shaped flowers of this attractive, branching plant are easily distinguished wherever it abounds as the Wild Indigo. A blue colouring matter has been made from this plant and used as a substitute for Indigo, but it is of a very poor quality. The root is valuable as a medicine in malarial fevers. It is also a stimulant and an antiseptic, and is used for healing purposes. In some localities the very young tender shoots are used as greens, like those of the Poke-weed, but if eaten when too far advanced, serious results are likely to follow. Farmers, especially throughout Maryland and Virginia, have great faith in this plant, and bunches of it are fastened about the harness of their horses to keep away flies. It grows from two to four feet high, and is very leafy. The foliage turns black in drying. The short-stemmed flowers have a light green calyx, and are loosely and sparingly arranged along the ends of the numerous branches. The foliage is of a dark grayish green. Wild Indigo blossoms in dry soil from June to September, and ranges from Maine to Minnesota, Florida and Louisiana.
