Assuming the species in question are ginseng, goldenseal, and black cohosh, look for a stand of mature hardwoods — typically beech, birch, maple, tulip poplar, oak, and cherry located on north- and northeastern-facing slopes. Some pines can be present but shouldn’t predominate. The site should have dabbled shade (70 to 85 percent) and the soils should be well drained and high in organic matter.
