Solangium (Potato plant)

Solanum
Unless im thinking of a different plant called Potato Vine...

Well I was nearly right ! The white one is very nice if a little tender.

it could of course be a white jasmine though it is doing well if it is. any chance of a photo?

My white jasmine is doing very well - and curving over the yellow winter one which started flowering a couple of weeks ago. Admittedly my postage stamp of a garden is very sheltered (typical Victorian terrace back-yard) but I saw a white one in a north London front garden last week still in full flower.
