The arboretum dates back to 1870, when the director of the "Rheinische Eisenbahn-Gesellschaft" created a large country house in the English half-timbered style, with park plantings that still remain, including two cedars ("Cedrus libani" and "Cedrus atlantica"), a "Ginkgo biloba", a "Sequoiadendron", and an incense cedar ("Calocedrus decurrens"). In 1921 the property was acquired by jurist Dr. Carl Härle, who actively planted a wide variety of trees and shrubs. After his death in 1950, his daughters Maria and Regina Härle maintained the property, and ultimately willed it to a nonprofit foundation in 2000.
