Clematis Repens

That is sweet.

looks altogether nicer,does it behave.

Thanks. I've only had it a few months but label says "ideal for patio container" so the assumption is, yes, Bjs.

Patio container it better be,let loose it may take over the world if one parent is Tangutica.
Just looked it up Repens suggests a species and they give height as 2 meters that I imagine is a years growth.
Like the flower shape a lot.
