Featured Plant - Red Maple Blooms

Red Maple Tree In Bloom Red Maple is one of the first deciduous trees to bloom in the spring. As you are driving toward the Arboretum or walking along one of the trails in late February and early March, you can see its reddish blooms beginning to appear in the upper forest canopy. Red maple has male and female flowers that occur on separate branches of the same tree, or a tree may have only male or only female flowers. The reddish bloom comes primarily from the female flowers and the fruits as they mature. The male flowers tend to have a yellowish color. The fruits, called samaras, are similar to those of other maples in having two wings. As spring progresses, you are likely to see abundant flower parts and later numerous samaras on the ground as you walk the Arboretum trails. Read more about this tree on our Featured Plant page.

Smartphone Lecture 2019 Over a 100 people were in attendance at “The Best Camera May Be the One in Your Pocket” program that was presented on Thursday, February 7, at the Oak Ridge Campus of Roane State Community College. Doug Edlund, Assistant Director of Operations, Marketing and Communications at the UT Institute of Agriculture, shared his tips and tricks to get the most out of smartphone photography. Doug also shared many of his personal photos and associated stories, plus techniques and settings on a smartphone camera that will help users fully utilize their devices. The program - co-sponsored by the UT Arboretum Society and the UT Forest Resources AgResearch and Education Center - was well received by the audience and Doug stayed well after the program was over to meet with members of the audience on their specific questions and needs.

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.

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.
