The UT Arboretum is a place for all seasons! Walkers can enjoy our over five miles of Walking Trails year round. There is always something in bloom at the Arboretum and our Featured Plants page showcases a different plant each month. Bird and Wildlife spotting is common during every season and holly berries abound in the Elmore Holly Garden during the holidays. Enjoy a virtual tour of the Arboretum via our Photo Gallery. The Arboretum and Arboretum Society hosts spring and fall plant sales, seasonal workshops, timely lectures, and special guided walks - even on New Year's Day!

Featured Plant - American Hornbeam

American Hornbeam is commonly found as an understory tree in bottomland forests along streams, but also on rocky ridges throughout the Eastern U.S. At the Arboretum numerous individuals can be seen along Scarborough Creek Road. The wood has been used for tool handles, bowls, and ox yokes. The fruits and buds are eaten by birds, squirrels, and deer.

Troop 46 sitting on the newly refurbished Oak Hickory trail treads. Stuart Row, Boy Scouts of America Scoutmaster - Troop 46, coordinated a service project at the UT Arboretum on April 15th. A small contingent of his scouts, and their dads, refurbished the trail tread stairs leading from the Oak Hickory Trail Bridge up and into the adjacent forest trail interpretive area. The work day was focused on hauling new chip aggregate in buckets up the stairs and then spreading/re-compacting the tread surface. This project is part of a long-term initiative by the UT Arboretum Society Trails Committee to improve and update the Arboretum trails, support infrastructure, and signage.

Host Your Event at the NEW Auditorium

The pastoral landscapes and vistas stretching across the rolling hills of the University of Tennessee Arboretum can create a picturesque setting for your meeting, wedding ceremony, or workshop. Our auditorium features nearly 2,000 square feet of open floor space, a beautiful stone fireplace, and exposed Douglas fir roof beams, creating a rustic park-like experience. The building has a small kitchen, bathroom, electricity, water, and parking accommodations for up to fifty-five cars.

The Arboretum Society

The University of Tennessee Arboretum Society (UTAS) is a non-profit organization of volunteers from throughout Tennessee, dedicated to furthering the objectives and programs of the Forest Resources Research and Education Center's Arboretum Project in Oak Ridge, Tennessee.

Chartered in 1965, the Arboretum Society has assisted the Arboretum by providing support and funding for such projects as expanding plant collections, constructing facilities to enhance the public's use and enjoyment of the Arboretum, and informing the public of the unique value and importance of the Arboretum to the area. Recently, the Society accepted the challenge of providing a portion of the operating funds needed to assure continued public access to the Arboretum.

Information about the Society and membership opportunities are available at the UT Arboretum Visitors Center or by e-mail at A history of the Society can be viewed on our web page UTAS History.

Inclement Weather

Please be advised that the UT Arboretum follows the same weather closures as the Knoxville Campus. In the event that our staff cannot make it in and/or the conditions are deemed unsafe, we will close the UT Arboretum and the gate will be up and locked. We ask that you refrain from entering the property at any time the gate is locked.

Professional Photographers Policy

The UT Forest Resoures AgResearch and Education Center (FRREC)/Arboretum is proud to provide an attractive venue for all types of outdoor photography in the East Tennessee region. However, considerable materials and labor are required to maintain the UT FRREC/Arboretum to the high standard that has attracted so many professional photographers for their photography sessions. As a result, starting on July 23, 2014 the UT FRREC/Arboretum implemented a new Photography Policy. Click here to view the new Photography Policy.
