The 30 acre Mt. Airy Arboretum is a magnificent collection of trees, shrubs and flowers, displayed alongside the beauty of nature. The Arboretum serves students, gardeners and homeowners as a testing and observation area for plant growth, habit and hardiness of plants in the Cincinnati area. Initially conceived in 1930, many individuals and organizations have contributed to the development and preservation of Mt. Airy Forest and Arboretum. You will see some of their names honored in special plantings, particularly in the garden areas.
