Plant Profile: Acer spicatum

Acer spicatum, commonly known as the mountain maple, is a deciduous shrub or small tree that typically reaches heights of 10 to 25 feet. It features a broad, spreading crown supported by a short trunk and slender branches. The leaves are arranged oppositely and are simple in structure, measuring between 2 to 5 inches in both length and width. Each leaf usually has three, and occasionally five, shallow lobes, with edges that are coarsely and irregularly serrated. The upper surface of the leaves is a light green and hairless, while the underside is covered with fine hairs. In the fall, the foliage transforms into vibrant shades of yellow, orange, and red, with the leaves attached to slender petioles that are typically longer than the leaf blades themselves. The bark is initially smooth and a dull gray-brown, but it gradually develops a slightly scaly texture. The fruit consists of paired reddish samaras, measuring between ¾ to 1¼ inches long, which ripen from late summer to early autumn.

Additionally, the sap of this tree can be harvested for sugar and boiled down to produce maple syrup. The bark is rich in tannins, making it useful in the leather tanning process.
