Chinese gesneriads

[Egon27]

I have two plants in China. I grow them in a shady, cool greenhouse. Has anyone grown them in the garden? How big can withstand frosts?

I don't know of anyone growing these outside in the UK. All are under glass and most kept frost free. Someone here may have another story to tell....
