Yup! About fifteen years ago I dug some wild ginseng to sell and I got three hundred dollars for one pound of dried roots. In order to keep from depleting the resource the buyer was giving sellers an ounce of seed to replant. This plant and quite a few others are the result of planting those seeds. Each year in august I collect the seeds and replant them too. Each berry has two seeds typically but sometimes three.
Yes demand is still high. I heard the current price is around $400.00 per pound of dried wild roots but I don't know that for a fact. In Wisconsin the law says the plant must have at least three prongs or leafing stems and a fruiting stalk to be legal to dig. I'm unsure how many years it takes to that point but I'd guess five years or more.
