Dogwood Test Garden
Tucked in a forested valley, bordered by a mixture of naturalized forest and developed land, the University of Tennessee Arboretum blends into the landscape so well that you might pass it by. This would be unfortunate, for much like the area where it is located, the Arboretum is a combination of collections and surrounding forest. It is a walking place, where a view up the valley is at the very least sufficient invitation for a stroll to a trailhead only a few yards away, easily reached along a graveled road. In springtime, flowering dogwoods and fruit trees brighten the grounds, while the buds on the hickories and oaks seem to anticipate the change of seasons. This is a beautiful teaching place, where native trees, non-natives, and cultivated varieties blend seamlessly.
