Yellowroot

Yellowroot (Xanthorhiza simplicissima)

Yellowroot (Xanthorhiza simplicissima) is a unique, low-growing deciduous shrub known for its spreading habit, finely textured foliage, and golden-yellow roots. Native to eastern North America, this adaptable, shade-tolerant plant is excellent for naturalizing, stabilizing slopes, and creating lush understory plantings.

Distinctive Features

Yellowroot forms dense colonies of upright, woody stems adorned with bright green, deeply cut leaves that resemble those of celandine poppy. Small, star-like maroon to brownish-purple flowers appear in early spring, followed by brilliant yellow fall foliage. Growing 1 to 3 feet tall and spreading up to 6 feet, this rhizomatous shrub provides excellent erosion control.
