quefolius L. [Araliaceae]) is native to the eastern half of
North America from Georgia to Quebecand west to the Mississippi River fromAlabama to Minnesota and westernIowa. It is an obligate shade plant thatinhabits the understory of hardwoodforests with well-drained, porous, andhumus-rich soils and is commonly foundon upland north- and east-facing slopes. It is also found in coniferous forestsand/or on south-facing slopes in soilscomposed mostly of sand and clay. Shadeand loamy soils are requirements forthriving wild populations.
family (Araliaceae), which includes 6species of herbaceous perennials foundin North America and Asia. All specieshave thick roots and palmately com-pound leaves borne in whorls. Thesmall, white flowers are borne in termi-nal umbels bearing a fleshy drupe con-taining 2 to 3 seeds after maturation.
Greek word “pan-axos” meaning “all-heal-

By the late 1700s,American ginseng was exported toChina by the American Fur TradingCompany. Ginseng roots and furs werethe first American exports by colonists(NYSDEC 2001). Heavy collectionfrom wild populations continued untilthe late 1800s. By the turn of the 20thcentury, American ginseng farmingbecame quite common throughout east-ern North America as wild populations
became increasingly rare due to over-harvesting. As a result, American gin-seng is a native North American plantintensively farmed as a horticulturalcrop. Hsu’s Ginseng Enterprises includecultivation on large farms and under

Cultivated American ginseng has beenexported to foreign markets for over100 y. It is one of the most well-knownherbal medicines and is widely con-sumed in Asia, North America, andEurope. Currently, over 75% of allAmerican ginseng production in the USoccurs in Wisconsin. Ginseng can bepropagated in fields or under existing
