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.
‘Deborah’ is a cultivar with an oval-rounded habit that is noted for its bright red emerging leaves that change over a 4-6 week period to deep maroon and finally dark green. Leaves display a wrinkled appearance with crinkled and undulating margins. Fall color is yellow-orange to bronze. Yellow flowers appear in clusters before the foliage in spring. Though small, the flowers have ornamental value. Flowers give way to samaras (to 1 1/2” long) with horizontally spreading wings. ‘Deborah’ was selected in 1967 as a seedling of A. platanoides ‘Schwedleri’. U. S. Plant Patent PP4,944 issued November 16, 1982.
No serious insect or disease problems. Susceptible to verticillium wilt which can be fatal. Anthracnose. Watch for leaf hoppers. Shallow root system can crack or heave nearby driveways or sidewalks. Shallow surface roots can interfere with turf. Bark is susceptible to sunscald and cracking (frost cracks) in winter, particularly on younger trees. Good resistance to leaf scorch.
Specimen tree for the landscape. Shade tree. May be used as a street tree as long as spread is not a problem.
