Hmmm, usually I get ten pics per post but I resize them for easier uploads (about 8" by 8" and let GW resize them further as needed).

Anyway going from your first post the type of begonias from top to bottom are wax (semperflorens) and usually considered an annual as they love very bright light and are easily found the next year at the nurseries, tuberous from all appearances (these go dormant in winter so stop watering when they drop their stems), tuberous (white bloom), and rex (semi-dormant but don't stop watering - just cut back severely in winter). Your second post is tuberous and a trailing/scandent (probably some form of thelmae - maybe 'Withlacoochee').

Welcome to the diversity of begonias! You will learn to recognize the types the more you get involved with them and also learn what are difficult and easy too.

You should accquire some angel-wing/cane types to diversify.

Umm, you kept a snail as a houseplant? I mean they do move slowly...but still?

I (truthfully) completely forgot about a type of begonia carrying that nome de plume. So, I really didn't know what you meant (thought I was yes, making a joke).

I'm not really very good at keeping many of the begonia types through winter. Give me an orchid any day....

They're easier outside in summer, and a few outside year round, like begonia evansiana

I have had the best luck with the cane types myself though.
