University of Tennessee Arboretum

The University of Tennessee Arboretum (250 acres) is a research and educational arboretum operated by the University of Tennessee Agricultural Experiment Station. It is located at 901 South Illinois Avenue (State Highway 62), Oak Ridge, Tennessee, and open weekdays without charge.

The arboretum contains approximately 2,500 native and exotic woody plant specimens, representing 800 species, varieties, and cultivars, with good collections of azaleas, conifers, crabapples, dogwoods, hollies, junipers, magnolias, oaks, rhododendrons, and viburnums. It also includes geographic groupings of plants from both relatively nearby habitats (Cumberland River gorge, Southern United States coastal plains) and elsewhere in the world (California, central China, and Poland), as well as four nature trails with interpretive signs.
