Dear Dylan, I got 1 from a botanical garden, they were so generous with me, cause I have helped them with some "charity work". And from a wholesaler. I have D. villosa from US. They have arrived with wild dug Trilliums, and D. caucasica (female). They are hardy here. I have a few other plants from seed, but not sure in the identity. I have noticed D. villosa from a batch of seedlings between D. caucasica. D. balcanica and D. bulbifera have died this winter, forgot to put them in a frost free place, -10°C killed most of the tubers, but maybe D. balcanica will resurrect. I try to plant them again. I try to get D. balcanica from Macedonia, it is said to be native there. I have new seeds, but they emerge after a cold winter, haven't sown yet. Most of my plants from seed are now 3 years old, some started to make inflorescences. And I'm trying to germinate Tamus communis, no success till now. We don't have so much climbing geophytes in commerce (Gloriosa, rarely Sandersonia and ever rarer Littonia, but none of them are hardy). Bye, Jan Z5a, Hungary
