- Broadleaf deciduous tree, 35-50(75) ft [11-15(23) m] high, dense foliage, broad crown, stout stems. Leaves opposite, simple, 10-18 cm across, 5-lobed, lobes pointed, glossy dark green above, also glossy below often with hairs in axils of veins, milky sap observed when petiole removed. (Compare to other common landscape maples.) Foliage sometimes develops an excellent yellow in fall. Showy clusters of yellow or greenish-yellow flowers in early spring, before leaves open, each flower about 8 mm diam. Large fruit, glabrous, wings wide spreading.
- Sun. Easy to transplant. Adapted to extremes in soils (sand, clay, acid, calcareous). Withstands hot dry conditions better than sugar maple. Tolerates pollution. Shallow root system may compete with turf and lift sidewalks. Over used in some areas.
- Hardy to USDA Zone 4 Native to continental Europe.
- Caution: most selections of Acer platanoides produce large quantities of seeds which can germinate rapidly and crowd out native species. Although not native to North America, Norway Maples have been found in second-growth woodlands near cities, especially in the northeastern U.S.
- Sometimes confused with Acer saccharum, Sugar Maple, see comparison.
