The Knoxville Botanical Garden and Arboretum (KBGA) is located on 47 acres of former Howell Nurseries, featuring walking trails, display gardens, unique & historic horticulture and over two miles of distinctive stone walls and timeless buildings, just five minutes from downtown. KBGA is a privately owned and operated Garden supported through donations and membership. Thanks to our members and local supporters we are able to offer these beautiful Gardens to the public for free!
