description
The Chinese Norway maple is a 10 to 12 meter high tree with gray-brown to dark-brown bark and bare, initially purple-colored shoots. The leaves are five to rarely seven-lobed, 6 to 10 centimeters wide with a clipped base. The lobes are narrow, pointed and usually with entire margins. The three upper lobes are considerably larger than the two lower lobes. Both sides of the leaf are shiny, light green and bare. When it shoots, the leaves are reddish in color and later turn olive green. The leaf stalk is thin and up to twice as long as the blade, and when injured it releases milky sap. The leaves turn red in autumn.
