The Norway Maple is the tree often mistaken for the Sugar Maple. This tree, of European origin, is commonly planted along city streets because of its resistance to smoke, dust, and insect pests.
While the leaf is somewhat similar to that of Sugar Maples, it is broader, thus usually wider than it is long. Norway Maple is a medium-sized, fast-growing tree, developing a rounded crown of dense foliage. The greenish-yellow flowers, in drooping clusters, and the winged seeds which develop from them are larger than normal maples.
One variety of Norway Maple has purplish leaves. Others are dark to light-green. If a fruit or stem is broken off a Norway Maple tree, it secretes a milky juice from the wound. This aspect is not found in Sugar Maples.
