Introduction
This 25-to 30-foot-tall native North American tree is reportedly quite similar to Acer barbatum or Florida Maple and is often seen with multiple trunks. The chalky white or light gray bark is quite attractive, with the bark on older trees becoming ridged and blackened near the ground. The two-to three-inch-diameter, lobed leaves, with fuzzy undersides, give a spectacular display in the fall months, ranging from shimmering yellow to vivid orange and deep red.

Use and Management
The striking white bark makes this maple well suited for planting as a specimen displayed against a dark background. A row of these maples planted along a dark glass building wall or other dark structure would get people's attention. Surprisingly underused, this small maple is well suited for a variety of sites, including residences.
Chalk maple grows well in full sun, partial shade, or deep shade, and has a high tolerance for dry soils. The tree is quite popular in the midwest in areas with alkaline soil pH.
