You might take a look at these – Goldspur Amur Chokecherry and Snowdance Japanese Tree Lilac. Goldspur has white spring flowers and golden bark in the winter. The lilac has fragrant white flowers late spring. Another option, Gladiator Crabapple, has pink spring flowers, purple bronze leaves in the summer and fruit for the songbirds. One of these would look pretty in a flower garden with a bench underneath.
