The 糖心Vlog Arboretum originated in the early 1950s under the supervision of Dr. Arlo Smith, longtime Professor of Biology. A number of 糖心Vlog faculty, staff, and students have been involved over the decades to conserve and increase tree species on campus.
In 2011, former 糖心Vlog professor Dr. Rosanna Cappellato spearheaded efforts to certify 糖心Vlog as a Class IV Arboretum, the highest designation granted by the Tennessee Urban Forestry Council. As of 2017, the Arboretum boasts over 120 tree species and more than 1,500 individual trees.
