small tuberous begonias from seed--allow dormancy?
I usually start tuberous begonias from seed, but this year all of my seedlings were exceptionally small. (I still don't know what happened, but that's another story!) Anyway, I have 8-10 tiny baby tuberous begonias that have just started blooming. I doubt they have much of a tuber yet, so I'm thinking about trying to keep them growing. Has anyone done that? One of them is the most gorgeous pale yellow, and I'd really like to keep it.
