How pretty! I can't tell from the pic, is it one with rhizomes?
I want to kill one too! I mean, I want one too! LOL!
Propagating immediately is what I try to do so I have to kill 4 or 6 of something to get rid of all of it. Sometimes it helps, sometimes not. Having to change conditions 2x per year is the main challenge I think. Begonias seem to appreciate consistency, not seasons.
