From Wikipedia, the free encyclopedia
Echinacea laevigata, the smooth purple coneflower, is a federally listed endangered plant found in the piedmont of the southeastern United States. Its current range is within the states of Virginia, North Carolina, South Carolina, and Georgia, although it was historically also found in Pennsylvania and Maryland. Most populations are found on roadsides and other open areas with plenty of sunlight, often on calcium and magnesium rich soils. Unlike other members of the genus Echinacea, it has not been traditionally used as an herbal medicine.
