Msiebert...
The ferns you have pictured will grow where ginseng grows... but they will also grow way outside of ginseng range too.
Planting where you find black cohosh would be a good choice.
If you can find the fern below (Maiden Hair Fern) growing on your place, that would be in my opinion the best place to put in a few test plots.
MHF requires almost identical conditions as seng... even requires higher levels of calcium in the soil to grow... and higher levels of calcium are a plus for seng.
Get you a pound of seed, or half or quarter... and put in a few small patches... and watch them as they develop for the next 3-4 years.. It takes about that much time to be able to tell if they are going to do well or not.
If you get to year 3 and you have some 3 prongers and nice 2 prongs... and then year 4 and 5 and some of those are producing berries and perhaps some turning into 4 prongs or nice sized 3 prongs... that is what you want to see.
When you get to that point.. you can sure step up the game and plant a lot more.
You will know which areas it grows better in and you can focus on those areas.
Good Luck !
