IdentificationNorway Maple is a commonly planted tree along city streets, less so planted by individuals in yards. The trees have smooth gray bark and a full, dense crown. Leaves are blocky and closely resemble Sugar Maple (A. saccharum), but the leafstalks bleed white when broken (vs. clear sap), and the flowers occur on ascending pedicels (vs. drooping). Fall color is not as bright as Sugar Maple.
