I am in zone 7/6b but near the city and my back yard is sheltered with a patio to provide some winter heat. I am thinking of adding an outdoors container with Begonia boliviensis. Anyone have experience with these? Overwintering and in the growing season? How do they do in both instanced in the mid-Atlantic?

Thanks.

PS I cross posted this on the begonia forum, but reckoned you all might also have experience.
