That is a tough question. There are so many variables that come into play. What are your goals in planting? Obviously we all want to buy the best seed at the lowest price possible.
With that said there is seed typically avail from $50 to $200 per lb for stratified ginseng seed with $70 to $140 per lb being the reasonable range and $100 per lbs being the average. The lowest price seed being from \"Shade Grown Field Cultivated\" gardens and the most expensive coming from so called \"Wild Simulated\" stock from the woods. But this is not always the case.
Now there is much to consider as there is everything from \"A\" to \"Z\" in between.
I have bought the best seed and had bad germination and I have bought cheep seed and had great germination.
Many studies have been done on the topic of how well a seed does if it is being shipped and grown in an area that it is not native too. For example will a seed from a plant in NY grow well in Tennessee and so on.
There are many concerns as to whether seed from cultivated stock in Wisconsin will have the genetics to endure the stressful conditions if planted in a woods environment. Many think that cultivated plants that are sprayed and pampered will produce seed that has lost its ability to adapt to conditions in the woods.
However, many say that growers in Wisconsin and Ontario have developed seed that has become hardy due to selective trait engineering.
Farmers are planting corn seed that has been developed over the years to be able to do things that farmers desire. So it only makes sense that ginseng growers in Wisconsin have done the same to seed that has been selectively harvested and replanted over the last 100 years.
I think it comes down to this. Call seed suppliers and ask why they recommend their seed. Buy some seed from different suppliers and see how their seed does. Last but least do not think that paying a high price for seed is going to give you the best seed or that buying cheep seed is going to give you the biggest bang for your buck. Very confusing I know.
You will learn what supplier works for you over time.
Here is a links of a few seed suppliers but there are other good ones out there that are not listed on this link. I am not suggesting everyone on this link is or isn't a good source to buy from. I am not going to recommend one over the other but at least this gives you some contacts:

Remember, this Wildgrown.com site sells ginseng seed and many state they have had great results.
