"Regular Begonia?"

I bought 2 beautiful Begonia this summer and they are still outside and have blooms, being a novice to these plants I have no clue if I can take a leaf and plant it? I cannot bring them in because they are so big that there is no room for them to have their right growing needs met. I hate to lose them but if I could save one of there leafs then I could still enjoy them next summer.
I also had 2 sets of birds raise their babies in them and so enjoyed watching the birds. Hope I can continue to provide a safe nursery for next years birds.
Thanks

Hi Mimi, it all depends on what kind of begonia you have. If you can post a photo of them that would help, if not, take a look at www.bradsbegoniaworld.com and see if you can determine which one you have.

Thanks so much for the site addy and from what I have read they are Tuberous Begonias. Also had all the info I needed to bring them in from outside. Thanks again.
