Acer platanoides, commonly called Norway maple, is native to Europe. It has been widely planted in urban areas throughout much of the U. S. It is a medium-sized deciduous shade tree typically growing 40-50’ tall with a dense, symmetrical, rounded crown. Leaves (to 7” across) have five sharply pointed lobes and resemble those of sugar maple. Leaf stems exude a milky sap when cut. Fall color is usually an unremarkable yellow. Small yellow flowers in erect clusters (corymbs) appear in spring before the foliage. Flowers give way to paired seeds with horizontally spreading wings (samaras to 2” long).
Species name means resembling platanus (sycamore), which is somewhat curious since the leaves of Norway maple do not really bear that much resemblance to sycamores.
