- Description
-
Yellowroot is a native deciduous shrub of eastern North America that can be found in it native habitat from New York to West Virginia and south to Florida and Alabama. It is not typically available commercially, but in its natural habitat is found on edges of streams or damp woods in sandy soil under a canopy of dappled sunlight. In North Carolina, it is found in the mountains and Piedmont areas. It grows 1-3 feet tall and spreads by suckers. Flowers appear in spring in drooping panicles and fall color is yellow to reds.
It will grow in well-drained moist sandy or clay loams in partial sun to shade. The best fall color occurs with some sun. Use this plant as a ground cover on banks of streams, woodland gardens and naturalized areas.
Its common name, Yellowroot, comes from the roots of the plant, which are yellow. The roots and stems can be used in dye making. Stems have also been used in basket weaving.
Insects, Diseases, and Other Plant Problems: Alkaline soils may lead to chlorosis. Under idyllic conditions, it may spread indefinitely by its suckers. However, planting within metal edging or having a concrete barrier such as a sidewalk can control its spread. Placing in full sun and insuring dry soil can also help to contain its spread.
