The history of Holden Arboretum
The arboretum was established through the efforts of Albert Fairchild Holden, who wanted to create a living memorial for his daughter. After his death, his sister and her husband donated land in Kirtland, Ohio, and the arboretum was officially founded in 1931. Over time, it has grown to cover land in two counties and several townships. Its collections include plants gathered from regions with climates similar to northern Ohio, such as parts of China and Korea.

The gardens are organized by plant type and theme, such as the Display Garden with lilacs and bulbs, and the Helen S. Layer Rhododendron Garden, which is set among mature trees.

Some areas require guided tours to protect sensitive habitats. Plant surveys and research help guide how these areas are cared for.
