The UT Arboretum is a project of the University of Tennessee Forest Resources AgResearch and Education Center. It generally hosts more than 30,000 visitors annually. This 250 acre research and education facility has over 2,500 native and exotic woody plant specimens that represent 800 species, varieties, and cultivars.

The UT Arboretum serves as an outdoor classroom to university students in a variety of fields. It is also a place that provides a natural laboratory for research in plant uses, insect and disease control, and the management of natural resources. The facility is recognized as an official Wildlife Observation Area and part of the National Watchable Wildlife Program by the Tennessee Wildlife Resources Agency. It is also recognized by the Holly Society of America as an official holly test garden and the trails are part of the Tennessee Recreational Trail System.
