Hi Val
Yes, Im from Bromley in Kent & yes I have had great success over the past few years growing Bananas (although I only leave my Basjoo's out to overwinter). I've just joined too and have just introduced myself by uploading a couple of photographs of my plants (see Hello from UK II) both before being wrapped up for the winter in October and at 10:00 THIS MORNING !!!. (before the rain came)
Regards
Phil
