The Knoxville Botanical Garden and Arboretum sprawls across 44 ridge-top acres crisscrossed by walking paths, dotted with display gardens, and ornamented by more than two miles of stone walls. Open from sunrise until sunset, the gardens—formerly Howell Nurseries—showcase local flora and fauna, inviting visitors to capture their beauty on camera or via their own personal sketch artist. Patrons can call ahead for guided tours of the premises, or attend events such as galas and educational workshops. Guests hosting upcoming events can also rent the facility for special occasions, such as outdoor weddings and corporate getaways.
