I can get them for you Whitjr, but its a might late in the year. Its still warm enough here, but I don't have time to do it now. If someone else doesn't come up with some for you this fall, hit me up toward the end of next summer.
I just looked over the list of plants that Maypop gave a link to and it is a really good looking site with a great amount of wild mountain plants. The prices looked good as well. The one thing that I think you should keep in mind is that you are buying these plants for shade purposes and if you get the ones that she is showing in the trays you will have to plant a lot of them to get the shade you need for your young ginseng plants. Ask her if she has large roots that will grow at least two feet tall or taller the first year. She probably keeps some for seed purposes that she may sell to you. You need roots as large as your fist to get plants this size and they will be more expensive when you buy them. They will get the job done because of how they will spread out and the tall seed pods they produce. Just some thoughts to ponder. Good luck with them.
It looks like you already have plenty of options available yo you, but if you still find yourself wanting some for early spring email me around the first part ofApril. The plants usually start pushing up around mid April, and i think they would transplant well if you could get them at this stage.... however, I have to agree with BCastle the best time would probably be in early fall when the plants go dormant.
