The following trees are recommended for use in all types of screens. Though smaller than the trees listed in planting lists in Sections B-12 and B-13, each of these trees will reach a height of at least twenty (20) feet.
(1) River birch (Betula nigra). Height twenty (20) to forty (40) feet; spread: eight (8) to sixteen (16) feet. The river birch is a native tree which usually grows along stream banks. In landscape design, it is adaptable to either high or low locations, but still requires a lot of moisture. This tree has an interesting papery bark and a graceful branching habitat. It has no special pest or maintenance problems.
(2) American hornbeam (Carpinus carolinia). Height twenty (20) to thirty (30) feet; spread: fifteen (15) to twenty (20) feet. This native tree has a natural yet refined appearance. It is slow growing, but at maturity it serves as an excellent small shade tree. Its fluted muscular trunk is an interesting feature. In the wild, the American hornbeam is common in moist rich soil, yet, when used in landscape design, it is soil tolerant and does not require an unusual amount of water. It has no pests and no special maintenance problems.
