Eastern Cork Tree

Eastern Cork Tree (Phellodendron) - Hardy summer-leafing trees about 50 feet high, from China and Japan, spreading in habit, and with large leaves cut into many leaflets. Of quick growth, they soon make a low round head, and thrive in all save wet soils. The bark is thick, light grey, and corky. They are being used in America for street planting, but are little known in this country. Increase by seeds and root-cuttings rooted in sand. The Chinese P. amurense is the hardier and more vigorous kind, P. japonicum being perhaps a form of it, and P. sachalinense, a promising kind, the last to come.
