- Description
-
Mountain maple is a native deciduous shrub or small tree in the maple family (Sapindaceae) found in the NE USA and in the mountains south to GA.
Slow to moderate grower reaching 10–25 ft. tall and wide with a bushy spreading crown and a short trunk. Plant in full sun to partial shade. It prefers cool, shady, moist soil.
The lobed leaves turn brilliant yellow, orange to red in autumn and are on slender stalks usually longer than the blade. The spring flowers are followed by paired winged samaras in fall.
The sap is a source of sugar and can be boiled to make maple syrup. The bark contains tannins, which are used in tanning leather.
This tree is not well-adapted to cultivation so is difficult to find at nurseries. It could be used in naturalized areas and is suited to the mountains of NC.
Insects, Diseases, and Other Plant Problems: No serious problems. See potential disease and insect problem fact sheets to the left.
The Clemson Cooperative Extension Home and Garden Information Center has a factsheet on common maple diseases and insect pests.
