Ok, seriously, I know nothing about begonias. But hubby loves them, so I bought two this year. When one looked sick, I came here looking for some info, but soon realized I know even less than I thought about begonias. From the little I read, I assumed if I asked for help, somebody would ask what KIND of a begonia I had, and I haven't a clue. Didn't even know there were different kinds (tuberous, etc.).

Did some googling, but even the basic sites did not go into explaining the different types of begonias, and how to tell one from the other.

Does anyone have a good online source that might educate me a bit?
