I've been interested to read that not everyone finds all the varieties easy to grow. I don't think I'm in Zone 10. I'm sure I'm Zone 9. But as we have said that doesn't mean a lot. My Zone 9 is much cooler in summer than a lot of zones with lower numbers. Perhaps the problem I have is my cool summers relative to where they grow naturally and I'm talking both day and night temperatures. A lot of the South American plants I grow and even some of the South African ones like it warmer in summer than it is here. I never knew the greenhouse we put in would mostly serve as a place for bulbs to stay warmer in summer. That wasn't the intention. But if Lee finds they grow really well for him that might be the difference and also why they do better for Lauw as well. So it could be a combination of things, not just my wetter darker winters. And since 'Rolf Fiedler' is considered a different genus and species, having a different experience with it would make sense. Does anyone know what conditions it had where ever it was discovered? I see seed pods on my white Ipheions and the pale blue ones that are happy in my summers too, but as Lee says they curl down close to the ground so it's easy to miss them. I don't sell anything I grow, but always understood that seedlings of 'Alberto Castillo' would no longer deserve the cultivar name. I think the man Alberto Castillo wishes people weren't growing on the seeds of any of the cultivars so they will remain pure, but I don't know how you'd stop that from happening. You'd hope that no one would sell seedlings under the cultivar names, but if the seedlings grow well and multiply well and get shared amongst friends who don't understand the naming system, as Jim McKenney suggested, the horse may already be out of the barn. As for Kelly's request for people to label their seed for the BX, explaining how they are pollinated, it's a great idea. But we've not even been able to get people to label their contributions as evergreen, winter growing , or summer growing as we hoped. For awhile we'd have help after the fact with that, but not lately. Sometimes there is very little information about the contributions at all. Dell passes on what information is supplied and often there will be something on the wiki. I'd guess most of what we get is open pollinated. It's a little like asking pbs list members not to include the whole message in their replies. You can always ask, but that doesn't mean you'll get compliance. Mary Sue
