Distribution and habitat
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]
