Hi Hillbilly,
Unless you are paying through the nose with Larry ($120+/ per pound), you are getting the very same seed from him, that you can get from most sang buyers for less. He wants you to pay for his expertise in growing as well as the seed. Don't get me wrong, he is a nice guy but, you can buy good seed cheaper. If you paid $65- or so a pound for seed from Larry Harding, what you got was seed from Canada or Wisconsin, that was raised on a ginseng farm under artificial shade. He will sell some of his native seed but, for much more then the normal stuff he sells. I paid $50/per pound this year through the WV ginseng growers association, but if you contact root buyers they should be able to sell you seed or point you in the right direction.
