Have lots to chose from. Check out my list and/or just ask as I have been lax about updating my list.
i don't have any (sorry), but from experience, this needs acid acid acid and a truely woodland, preferably evergreen, environment. I tried growing it twice and had no luck. hope you find some.
I believe that I have the correct environment for it. My soil is acidic around 4.5 to 5.5 depending where I put it and I have evergreens, oaks, maples and chokecherry's growing all around. I found a source in Michigan that has decent pricing and doesn't have a minimum order value so I think that I will try there. Thanks for the response.
