Begonia i.d. please

B. brevirimosa. Not sure if it is subsp. brevirimosa or exotica. The only difference I saw when I had both was the color of the stem - one was green and the other red. They are both native to PNG (Papua New Guinea).

Wow. That is a beautiful begonia! hc, would it be better in your opinion to try and find the species or get this variety?

It is the same thing. Not sure what the 'Edinburgh' really signifies (a select strain like 'Bonfire' is to boliviensis?)

Well, I just ordered it. Along with Caravan and Tiny Gem. Does anyone know of a support group for begonia addicts?
