I live in VA up against the Blue Ridge on the northern tip of the Appalachian's temperate rainforest area. I've been growing A. americana and I did grow A. fortunei for a time before removing it as my desires shifted towards native species whenever possible. I have wanted to try my hand at A. priceana for a while but have never been able to find a source for seeds. I know Mountain Garden down in NC has some plants but they do not sell the seeds, at least they do not publish the sale of the seeds. Given its status as endangered I was surprised that I could not find any source of seeds, since I'd presume that the distribution of seeds would help remove the endangered status.
Does anyone know where I could find a few seeds? I really admire this particular plant, it's so beautiful and would love to add it to my small perennial garden.
We run a small, .25 acre, urban homestead with the goal of producing 50% of all foodstuffs consumed.
Last Fall I got some A. priceana seeds from Joe and Geoff at http://mountaingardensherbs.com/index.php/products/seed-list/ . They're a seasonal item, and are harvested some time in October each year. I stratified, filed, and planted in sandy soil last spring, and had very good germination, but unfortunately my climate is too dry and windy for them. I lost all of the young plants, most likely because I was not able to re-create the sandy, damp, river like environment they are happy in.
I have eight seeds left, and am happy to send them to you by SASE. From what Geoff said they need to be planted or stratified soon after harvesting, so it is probably the safest bet to also get on Joe and Geoff's mailing list to get seeds this coming October. Send me a PM and I can give you my mailing address-
Also, if it's improved varieties of Hopniss that you have, I would be interested in swapping you some tubers this coming fall – I have several of the improved varieties from Dr. Blackmon's and Dr. Cannon's breeding experiments –
