evr - Since I don't sell and am not a "for profit grower", I feel I can enjoy any and all seeds that I not only grow for myself, but any seed trades. I think if I was selling seeds for a particular cultivar, I'd feel obligated to guarantee that those seeds would grow true. I know folks who have bought expensive seeds on ebay and did not get what they thought they were getting. Sometimes it's a costly disappointment. I've talked with many folks who will no longer purchase from ebay. I imagine that the DG Market could produce some disappointments, too. Where money is involved, so is accountability. Even in seed trades, people can become disillusioned with trading if they get seeds that don't germinate (because they are old and no longer viable) or turn out to be a totally different plant or I've even gotten dried petals and no seeds in some trades because some folks don't know what the seeds look like. But I personally am willing to take the chance with trades, whereas spending $$ for seeds with no guarantee is not something I can personally afford. I do purchase seeds from reputable sellers.
Oh cool! I have never grown Clematis from seeds. Have you? If so, do they need cold stratification to germinate? The Clematis that I am growing came from tiny starts (possibly volunteers) that I traded for. All of them that I have came from up North where there are winters.
