Plant (West Hill TN34)

Largish plant, probably about 18 inches high. It was flowering when I bought it about 10 years ago and produces lovely white trumpet-like flowers but it’s never flowered since so I’m obviously doing something wrong. It puts out fine tendril-like stems which wind around anything nearby so could do with some kind of frame. I currently have it tied to sticks with a piece of string! Collection from Nelson Road.
