Hi MTLL, a pitty Mauro Peixoto has no more seeds available
, I suppose you mailed him about that. And no I didn't collect any seeds from my plant.. so cannot help you with that either. I have been searching too and found that you might have a chance with the American Begonia Society, the only drawback is that you have to be member in order to purchase seed.
