The Norway Maple (Acer platanoides) is a species of maple native to Europe and western Asia. In its native range, the Norway maple may live up to 250 years, but often has a much shorter life expectancy when used on streets where insufficient space for its root network can limit its life span. It is a deciduous large tree with broad, rounded crown. Flowers are bright yellow-green in erected rounded clusters and appear in early spring just before leaves. Bark on young trunks is faintly striped, unlike native maples. The bark of mature Norway maples is grey-brown and shallowly grooved. Unlike many other maples, mature trees do not tend to develop a shaggy bark. The fruit of the Norway maple is a double samara with two winged seeds. The leaves are arranged opposite on the branches. They have five lobes with one to three side teeth, and an otherwise smooth margin. The autumn color is usually yellow, occasionally orange-red. William Bartram of Pennsylvania had Norway maple by 1756, but credit for its introduction to North America is attributed usually to 1784 and William Hamilton. As the tree is tolerant of heat and drought it has become widespread thoughout the USA. Its genus name comes from the Latin, Acer, for maple trees. Its species epithet refers to the leaf of the plane tree, Platanus. There are many cultivars of the species.
