A merican ginseng
(Panax quinquefolium L.) is a shade-requiring, herbaceousplant native to the hardwoodforests of eastern North America.
Its fleshy root and short under-ground stem are perennial. Theleaves and stems die at the end ofthe growing season and regroweach spring.
Ginseng is best adapted to cool,temperate climates. Its range inNorth Carolina is generallylimited to the mountain andfoothill counties of the westernpart of the state. Rarely havenative stands been reported east ofa line connecting Gaston andStokes counties.

North Carolina State University The most favorable temperatureand soil moisture conditions forginseng production are generallyassociated with north- or east-facing slopes. Southern andwestern exposures are usually toowarm and dry for good growth.
At higher elevations and in coolerclimates, however, exposure is ofless importance. A sloped site isdesirable because good surfacedrainage is important. Wetconditions usually result in rottingof the ginseng roots.
