I have some of these available in packets of 7 seeds. I have successfully grown these from seeds and in fact collected these from a plant which I grew from seeds. It takes 2 years for the seeds to go through a double germination and it will be about 4 years to see your first flowers, but it's very rewarding once you do.

Here are photos of a few plants I've gotten from my peony seeds.

Make me an offer or let me see your trade list if you are interested.
