Begonia Rex "Escargot"

Whilst I may take either on of you up on the offer of newbies and thank you both for the offers, atm my last leaf section isn't rotting but nor is it producing babies. I'll wait and see if the leaf does anything before calling in reinforcements. I might put it in the airing cupboard to give if a bit of warm. I've got it on the kitchen windowsil which could get a bit chilly overnight.
