tnginseng - welcome to the forum.
I am a long time ginseng hunter but also new to the forum here.
Most of the folks who know timber also know ginseng, yellowroot, etc - so I expect your guy knew what he was talking about.
If the TN in tnginseng is for Tennessee (like it is in my TNhunter) then I thought I would send you a few images from my backyard this morning.
Late last fall (when the ginseng was about to die out) I transplanted a few small roots up to a location just off my back yard in the woods. Now I can walk out about 100 ft from my back door and view my own little start of a ginseng patch.
The roots that I brought to this patch last fall were from small 2 prong plants and I only trans planted about 20 roots but a few of them came up 3 prong-ers this spring.
Below is a pic of one of the nicer 3-prong plants.
This will give you a good idea of what Tennessee Wild Ginseng looks like on June 22, 2010.
