Jim:

Begonia sutherlandii is not winter hardy here...we have lost established 
plants at 15F, so I'd say Zone 8b. We have also not had any luck with 
Begonia 'Bonfire', although certain clones of the parent B. boliviensis 
are fine here. I can only assume the other parent used in the Bonfire 
hybrids was less winter hardy.
