Happy, re: Hardy Begonia< begonia grandis.

Yes, some will reseed in to pots below and small baby plants will emerge. I prick out the babies and pot into 4" pots. They will be bloomimg size by second year and still small enough by our usual Spring Plant swap to transport. Since you became our main 'supplier' I have stopped doing this for swaps. You could also cut back bloom stalks that are ripe and layer them over flats of soil so 'seeds' (They look like little yellow bulbils similar to osmocote!) will drop there....say, one for pink and one for white and then prick out from there. In any event, they do not need much soil! (See pic #4 ) If you prick out/pot up some one year plants now and overwinter them, they should be good to swap in Spring once they emerge.
