Don't know what this is.....

It looks like a Sycamore tree, Pip, but I'm not sure which one.

Is it a climber Pip? Lovely isn't it!

The stipules--the little leaf-like thingies where the leaf joins the stem--are pretty indicative of Sycamores (Platanus species).

Thanks Karen and Tugbrethil :o)

Ah, right Tugbrethil. I see that now. I thought it was growing from that, like a vine.

It does look a bit like a climber from the camera angle, though, doesn't it!

Yes, it reminded me of a grape vine!

That was my first thought, then I thought "Lavatera?", then the light dawned! : D
