Jealousy here! These are all gorgeous! I'm in 7A and haven't ever had a bloom, but I have a couple of stalks threatening to bloom. I had one AB I bought last year, but it didn't make it. My fault, though....I heard they needed to be drier than others, but I let it get too dry.
Carry on with gorgeous 7A blooms--I hope I can follow you with ordinary TBs soon!
