Just read a review in Fine Gardening about Cool Splash bush honeysuckle (Diervilla sessilifolia 'LPDC Podaras' which will do well in dry shade and hard clay soil, as well as sunnier more fertile areas. It has pretty leaves with a white margin, and yellow flowers. Attracts butterflies and hummingbirds, deers don't like it. Spreads by underground suckers, so you'd need to watch that. 2-3' tall and wide
