PRINCETON SENTRY® Ginkgo is a large tree selected for its upright conical form. It is a male clone, which will not produce the distinctive smelly fruit, and will develop into upright narrowly pyramidal shaped tree. With increased age, it will mature to a large 50' by 30' tree. Its narrow shape makes it work well as a street tree but, due to its ultimate mature height, should not be planted under power lines. The Ginkgo is an ancient deciduous conifer and evidence has been found which shows this tree coexisted with the dinosaurs. Ginkgo is sometimes called the maidenhair tree due to its beautiful fan shaped leaves that resemble a maidenhair fern frond. It is one of the most pollution-tolerant trees and works well in the city. Insignificant green flowers appear in the spring. Ginkgo has wonderful yellow fall color. It produces stout spurs along the branches; these spurs and the stiff branches give the Ginkgo a formal, stiff, spiky appearance in winter. Golden yellow fall color is outstanding.
