Streptocarpus, the Bristol's cultivars

Is anyone in a position to tell me about all the Bristol's cultivars of Streptocarpus? Is there someone out there named Bristol who is introducing all of these awesome cultivars? There are so many and they are incredibly interesting. I particularly like Bristol's Very Berry, Bristol's Ribbon Pink, Bristol's Watermelon Wine (love the color of that one), Bristol's Doo Wop, and Bristol's Goose Egg. These cultivars are some of the most interesting out there.

Well, the Bristol's line of strps comes from Rob's Violet Barn... he could tell you more than anyone.

They are all very pretty!
