Viburnum "Dawn," which is apparently tall, narrow, arching, with fragrant pink in spring and good foliage thereafter?
With: tall conical holly, mounding camellia, some Helleri Holly or small boxwoods for the front, and New Jersey Tea, baptisia, peony, and iris, and possibly caryopteris if there appears to be room in the middle. With some Rozanne geranium or ajuga to fill in. And dwarf deutzia. And it is not all going to fit.
