Acer spicatum

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.   Growing at a slow to moderate rate 10–25 ft. tall, forming a bushy spreading crown with a short trunk and slender branches.

The leaves are opposite and simple, 2 - 5 in. long and wide, with 3 or sometimes slightly 5 shallow broad lobes. They are coarsely and irregularly toothed with a light green hairless surface and a finely hairy underside. The leaves turn brilliant yellow, orange to red in autumn, and are on slender stalks usually longer than the blade. The bark is thin, dull gray-brown, and smooth at first but becoming slightly scaly. The fruit is paired reddish samara 3⁄4–1 1⁄4 in. long, maturing in late summer to early autumn.

Plant in full sun to partial shade.  It prefers cool, shady, moist soil.

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.
