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)
HONEY LOCUST TREES – 1949
The Siebenthaler Company has made a lasting contribution to horticulture and the beautification of cities and county alike by the development of unusual trees and shrubs. At the top of the list of importance is the Moraine Locust. The Moraine Locust, developed by cross pollinating, has been used as a major replacement for the American Elm. It has a distinctive vase-like shape, bears delicate, lacy leaves and has a fast growth, attaining a height of 60 feet and a width of 40 feet. It has no pods and is thornless. The small leaves permit the sunlight to reach the grass beneath. It is a hardwood tree whose roots grow deep, enabling it to withstand both droughts and floods. It is amazingly tolerant of smoke and soot and is resistant to disease. These qualities make it a fine selection for city streets and parks. the Moraine Locust has been chosen one of Americas twenty best shade trees by the International Shade tree Conference
MORAINE ASH – 1949
The Moraine Ash has many of the same qualities as the Moraine Locust: A graceful foliage of small leaves, clean habits, and exceptional durability. It is smaller than the native Ash and has darker green color. It is fast growing and reaches maturity at 15 years, with an average height of 30 feet. Sadly, the Emerald Ash borer has decimated this country’s native and Moraine Ash populations.
