Baptisia tinctoria (common names include yellow false indigo, wild indigo,^[1] wild-indigo^[2] and horseflyweed^[3]) is a herbaceous perennial plant in the family Fabaceae. It is native to eastern North America.

Distribution[]

Baptisia tinctoria is found throughout the eastern United States, west to Minnesota, and south to Florida.^[4] As it is rare in some parts of its range, it is protected by some state authorities: in Kentucky it is threatened; in Maine it is considered endangered.^[5] It prefers dry meadow and open woodland environments.^[6]

Description[]

The multiple bushy stems of Baptisia tinctoria reach 2 to 3 feet tall. The leaves are silver-green; each is divided into three leaflets about ½ inch long. The flowers are yellow and grow in spikes 1½ to 3 inches long.^[7]

The leaves are eaten by some lepidopteran caterpillars, for example the Io moth (Automeris io).

On Martha's Vineyard, the species is a tumbleweed: it grows in a globular form, breaks off at the root in the autumn, and tumbles about.^[1]
