I'm making myself feel dizzy turning sideways to look at this - any chance you could put it the right way up, lol! It's most definitely not Jasmine...

there you go. sorry

Is it attached to the stick behind it with a garden centre green plastic tape tie? Or just leaning on the stick?

I hope it's a weed as I have just pulled something very similar up!

Attached to the stick. A colleague is suggesting some sort of hyacinth bean.

Well if its attached by that tie, then it must be something you've bought - but it isn't something I recognise at this size. Better just wait and see as it grows - now I'm curious as to what on earth a hyacinth bean is...

It was in the garden before we moved in but overgrown and i found it when I cleared the garden out. will see what it grows into. thanks

Hyacinth bean is one of the Lablab ones also known as Dolichos. Sad to say that does not look like it though.

maybe periwinkle
