PUSHING THE BORDERS

This grew up behind a Cordyline this year, I left it to grow and whilst nothing special to look at it does have quite attractive flowers so has been left in place.
It isn’t self supporting so far but scrambles upwards through other plants so I’m attempting to train it around the Cordyline although I don’t know if it’s hardy yet.
Any ideas as to what it could be please?

I think I can get to genus.

I think it is a Lycium, which gives goji berries.

I don't know how to distinguish between Lycium barbarum and chinense.

ps. I do now.  Lycium barbarum has two sepals, and chinensis has more.  I hadn't realised how large the genus is [Kew recognise 100 species]. I was only aware of two!
