This arboretum was founded in 1926, on what was once the private estate of Stanley M. Rowe. The grounds occupy over 40 acres of land in the historic village of Mariemont. Tree-huggers will be thrilled with the collection of crabapples, conifers and oaks found on site. Don't forget to check out the magnificent magnolias, viburnums, lilacs and late-summer-blooming trees and shrubs.
