I don't know the name, sorry.

Sure is lovely though, nameless notwithstanding.

Looks a bit like a four o'clock flower, the leaves are similar, is it funnel shaped?

I looked up Four O'clock flower and this is different. My friend had the 4 O'clock flower plant and the flower is much smaller than this one. This plant is somewhat viney and is growing on a trellis. Thanks for giving it a shot Grammazoo :)

Sorry Tracy - try posting the photo in the questions section; someone should recognise it?

No worries Grammazoo :) I'm sure if I asked someone at work they'd tell me the name. Will try the (?) section as well.
