The kids will love learning about flowers, plants and all the other natural wonders that inhabit the Knoxville Botanical Gardens and Arboretum. This 44-acre garden features an historic landscape that is adorned with foliage and plants that are not only indigenous to the area, but also combine to create a natural oasis that is as relaxing as it is beautiful. There is also a plant nursery on site that houses even more picturesque greenery.
