Ornamental ivy, Hedera helix ‘Shannon’, Its foliage is made up of 3 to 5 deeply divided lobes, which could be mistaken for leaflets. The base of the lobes is sometimes slightly pinched...
Overall, this is an ivy in the same spirit as ‘Shamrock’, from which it is descended. But the lobes are longer and wider. The stems are much taller, with longer internodes.
It is a good climber with thin foliage. The centre of the leaf turns red where it intersects the petiole that supports it in winter.
