any one of several plants with yellow roots

The Yellowroot is the only member of the genus Xanthorhiza, and one of very few genera in the family Ranunculaceae with a woody stem. It is native to the eastern United States from Maine south to northern Florida and west to Ohio and eastern Texas. It contains the alkaloid berberine, which has a number of traditional and contemporary uses for dying and medicine. The genus name as well as the common name refer to the plant's yellow roots, which was used to produce a yellow dye by Native Americans. The species name refers to the simple root. In the wild, it grows on the edges of streams in sandy soil under a canopy of dappled sunlight. In cultivation, it is often provided with more sunlight so that the fall colors are more vivid. It is a subshrub, reaching 20–70 centimetres in height, with stems up to 6 millimetres diameter. The leaves are spirally arranged, 10–18 centimetres long, each divided into 5 toothed leaflets, and flowers emerge only from the upper portion of the unbranched stem. The flowers are produced in broad panicles 6–20 centimetres long, each flower small, star-shaped, reddish brown to purple brown, with five petals.
