Our next feature on this wet Wildflower Wednesday could actually be classified as a small shrub!
Yellowroot (Xanthorhiza simplicissima) is the only member of its genus and one of the few woody members of the buttercup family. This deciduous plant forms a thicket of suckering stems starting about a foot tall and increasing in height each year up to three feet. Native to forested stream banks and other moist woodland areas in portions of the eastern and southeastern United States, yellowroot is an adaptable ground cover that can help stabilize shaded slopes. It will adapt to a wide range of soil conditions including wet, dry, or clay. It will also adapt to varying sun conditions ranging from full sun to full shade, although it grows and spreads most readily in part shade and moist, acidic, humusy soils. Spread can be controlled with concrete walkways, metal edging, or by siting in a drier location. Unique starry purple or maroon flowers emerge from the stems in early spring before the leaves come out. The foliage is bright glossy green, lacy, and divided. In autumn, yellowroot is at its showiest. The leaves turn yellow, then bright red, fading into tan and persisting into winter. The small seeds are eaten by a variety of wildlife. The roots are indeed a bright yellow and crushing them yields a yellow dye. The roots have been used traditionally to treat various ailments of the digestive and circulatory systems. Deer tend to avoid this plant. Use yellowroot in shaded woodland gardens, under deciduous trees, along shady stream banks or pond margins, and other places where a naturalized ground cover is desired.
