I've sort of turned into a begonia-addict of sorts .....and have been going on a shopping spree of late. Have purchased some Cane begonias, but my available space is limited. I grow my plants under gro-lights and would like to find smaller-growing rhizomatous begonias . Can anyone recommend a few for consideration? Many thanks.

autumn embers, Kit Kat, Rajah are nice

Begonia 'Phoe's Cleo' has stayed under 8" in its pot here -- 5.5" without the pot. It is growing in a cool shaded southern window. Lovely!
