Good pictures! Lucky you to find a source for houseplant begonias. The first two are rhizomtous so will not tolerate overwatering, but don't panic if they dry. If B. 'Escargot' is doing fine, congrats, as many people struggle with it. If you are going to overwinter it and 'Cowardly Lion;' they will need additional humidity, but that is just my opinion. The two Rexes are thin leaved and will not tolerate direct sun, they must have good humidity too, will probably be okay if grown closely with the others, the closer they all are the better humidity for all of them. Paradoxically, Rexes need strong light to hold that red color. I think you are doing fine.

Hmmmm. so I guess I should bring them in from the monsoon we are experiencing? I just sort of leave them on the patio all summer and water when it hasn't rained in a while. Needless to say, that is where Escargot lived all last summer and is currently residing. I've overwintered them in my FL room which is south facing, so they get decent indirect light all winter.

Suggestions on what to do with Cowardly Lion which is a big fat nekkid rhizome and no leaves? Should I unpot it and cut that thing in half and repot in a better position?

Thanks so much for your response!

Oh lucky you with a florida room. Can I send you my begonias for the winter?
I really like your new red ones, and Escargot. I think I would just throw the sad one away.

In a true spirit of enabling, here is a link.

Yes, I would cut the tip off 'Cowardly' and root it, you should get a plant from the base and the rest of that rhizome could be placed on damp sphagnum and likely you will get plants there also. I guess I need not try to tell you about humidity!

I just had to say how beautiful your collection is..

You could put Cowardly Lion in a hanging basket when you get more plants from the rhizome. It's one of my favorites. Most begonias will get fairly large, and you're doing great with them. Be careful about the soil you put them in, though. Regular potting soil holds too much water and they'll rot.

Thanks again for the advice and nice comments. They are all outside on the patio - living in our tropical conditions and frequent monsoons. Yes, we usually get rain in the spring, but this past season has been unbelievable. They all seem to be growing in front of my eyes, I will have to get updated pictures.

Thanks again everyone!
