Botanical Name

Plant Common Name

Norway Maple

General Description

Norway maple is a fast-growing deciduous shade tree native to Europe but naturalized in the United States and elsewhere. Introduced in the late nineteenth century by Van Houtte Nursery of Ghent, Belgium, 'Globosum' has a dense low spherical canopy and dark green, five- to seven-lobed leaves that turn pumpkin yellow in fall. The young foliage is bronze-tinged. The leaf stems exude a milky latex if severed. The clustered yellow-green flowers are more abundant and conspicuous than those of many maples. This selection has only male flowers and produces no seeds. The bark is dark gray and fissured.

Norway maple is very tolerant of a wide range of sites and conditions but does best in locations with full sun to part shade and well-drained average soil. This tough and adaptable tree does well in urban settings. Its dense roots and shade and its penchant for prolific self-sowing make it a poor choice for gardens and natural areas. Its sale is banned in Massachusetts and several other areas because of its invasiveness.
