Begonia Rex "Escargot"

My rooted leaf has babies at the bottom. I didn't expect that! Next time I'll leave less stem in the water.

I'm jealous,  my leaf stem just went to mush. I got the cuttings out of the airing cupboard, I didn't want them to cook in the dark, but the leaf cuttings are quite flacid and no growth whatsoever.  I'm resisting digging them up to have a peek in the nether regions for roots.
