Holden Arboretum, located in Kirtland and adjacent townships in Lake County, Ohio, spans over 3,600 acres of cultivated collections and natural areas. Founded in 1931, it serves as a center for botanical research, conservation, and public education. The arboretum integrates extensive cultivated gardens with preserved hardwood forests and wetlands representative of the Great Lakes region. Its diverse plant collections cover rare trees, shrubs, wildflowers, and seasonal blooms, attracting horticulturists and casual visitors alike.

Key landmarks include the Emergent Tower—an impressive 120-foot steel structure that offers panoramic views of the surrounding forest canopy and Lake Erie on clear days. The Arboretum also features specialized gardens such as the Ginkgo Collection and Rhododendron Display Garden, as well as outdoor sculpture installations enhancing the landscape’s artistic appeal. Educational programs range from plant science workshops to family nature adventure activities, fostering connections with the environment.
