Foliage composed of 3 to 5 deeply divided lobes, so much so that they could be mistaken for leaflets. The bases of the lobes are sometimes slightly pinched.

Broadly in the same vein as ‘Shamrock’, from which it is descended. But with longer, wider lobes, much larger stems and longer internodes.

A good climber with thin foliage. The centre of the leaf turns red where it intersects the petiole in winter.
