Norway Maple

LEAVES: Opposite, simple, coarsely 5-lobed, 4″-7″ wide, milky sap exudes from the broken leaf-stalk.

TWIGS: Stout, reddish-brown. Buds glossy red with green at the base, bud scales with keel-like ridges. Leaf scars meet to form a sharp angle, encircling the twig.

FRUIT: Wings wide spreading to nearly horizontal, maturing in autumn.

BARK: Smooth and light brown on young trees, dark and fissured but not scaly when older.

GENERAL: Imported from northern Europe and extensively planted along city streets and in parks. Norway maple typically reaches 50′ high. It frequently escapes from cultivation to grow in disturbed woods and roadways. Norway maple can be distinguished from other maples by the larger leaves, milky sap of the petiole, and the horizontal wings of the fruits.
