Answer: Your choice will depend in part on the amount of space available for the shrub to grow and mature, how sunny/shady it is and at what time of day, the type of soil where you want to plant, wether that spot is extra wet or extra dry or average, and whether or not it is windy especially in the winter. Some shrubs to consider might include smaller cultivars of Clethra alnifolia, PJM and other small growing Rhododendron varieties with good winter hardiness, yews, and the white flowered Hydrangea arborescens. A professionally trained nurseryman should be able to help you evaluate the growing conditions where you want to plant and identify plants that would thrive there. Then you would select from among those based on your overall design goals and your personal preference. I hope this helps you with your research.
