Opinion
"
The Walter dogwood is an interesting tree native to central China. Good seasonal features with beautiful white flowers in the spring, dark green foliage throughout the summer and showy red autumn colour’s that hide small black fleshy fruits are its outstanding features. The berries attract a variety of birds, squirrels and other wildlife. The bark has a very unique and interesting pattern that resembles the hide of an alligator. It grows as wide as it does tall and can be used as a shade tree or possibly even a residential street tree. Handles drought well and doesn’t get many pests or diseases.
