Kousa dogwood is an excellent small specimen tree, especially when it is used as a foundation planting near the corner of a house to break up vertical lines. Two of this plant's outstanding characteristics are four-petaled, white flowers that appear above the foliage in June and reddish-purple fall color. This tree benefits from a layer of mulch to maintain a cool root environment.
