The Siebenthaler Company has always been known for innovation. John Siebenthaler, born in 1898, took over the growing of plant material as his major responsibility in the business. Once the Beavercreek land had been purchased in 1947, John worked tirelessly cross breeding new varieties of trees. During this time, he developed many new varieties of lilacs and two of the nation’s most important new shade trees (Moraine Ash and Moraine Locust)
