Yellowroot 2 Gallon

Yellowroot (Xanthorhiza simplicissima)

Yellowroot (Xanthorhiza simplicissima) is a low-growing, native deciduous shrub valued for its finely textured foliage, deep purple spring flowers, and brilliant golden fall color. Also known as Shrub Yellowroot, this adaptable species forms attractive colonies and is especially useful for naturalizing shady, moist woodland areas.

Distinctive Features

This stoloniferous shrub typically grows 1 to 3 feet tall and spreads to form dense colonies via underground stems. Its delicate, fern-like leaves emerge early in spring and turn a vibrant yellow in autumn. Small star-shaped purple-brown flowers appear in clusters before the foliage fully expands, adding subtle early-season interest. Its roots contain a natural yellow dye, giving the plant its common name.
