Well shoot, I certainly wasn't trying to discourage anyone from growing cristate forms! Personally, I think Sculpted forms are the most interesting, fun and exciting form to grow and hybridize. The seedlings continue to surprise me with what they will do. There's no reason to jump the gun and get rid of yours Nancy. Give them a chance to really settle in and then decide, if nothing else you could make some seeds
As far as I know Bee's Bob Baker is pollen fertile. I haven't grown it, but either purchased or was gifted seeds of a TFF x BBB cross years ago. There are other cristate cultivars that are reliable producers of cristate blooms. As I mentioned Texas Feathered Fancy might be a good diploid to try, a 2006 intro so you should be able to find it reasonably priced. I don't grow Greetings Earthling or Emperor's Crocodile two of the newer diploid cristates, so can't comment on them. Wooster Mindcraft was new here this summer.
