Ok, maybe honeysuckle....it does well in part shade. A clematis called Nelly Moser prefers shade. I think buddleia will still be fine. Cotoneaster Horizontallis is an evergreen shrub with red or orange berries that will lean against a fence or wall. Clematis montana is a vigorous climber with masses of spring flowers. Is soil reasonable.? Is it dry? So,it's a part shade garden and not total shade? Aconitums are tallish herbaceous plants....growing 4 or 5 feet....with blue, purple or white flowers in mid to late summer that like some shade. Acteas are tall too with colourful foliage and scented summer flowers. If there's moisture there dogwoods will give height and colourful red stems throughout winter. Smaller plants like Astilbes, Geraniums, brunneras, Heucheras may fit that situation. The more info you give the better we can visualise your garden
