A mat-like, spreading shrub with erect, leggy stems to 3 ft. The bark and long roots are deep-yellow and bitter. Attractive foliage is once- or twice-pinnate, glossy and green, turning yellow to reddish-purple in fall. Many tan-colored leaves persist into winter. The small, star-shaped, purplish-brown flowers are in crowded, terminal clusters. Fruit is a dry, yellowish follicle. The genus name as well as the common name refer to the plant's yellow roots (xantho- meaning "yellow" and rhiza meaning "root"), which was used to produce a yellow dye by Native Americans. The species name refers to the simple (not branched) root.
