Mountain Maple is a small, understory tree that occurs in Maryland's western mountains.


Mountain Maple can easily be confused with Striped Maple. The leaves of Mountain Maple, however, tend to be smaller and narrower than those of Striped Maple, and they are more shallowly lobed. Also, the bark of young Mountain Maple lacks the greenish color and white vertical stripes of Striped Maple. The flowers of both species are spikes that appear after the leaves in spring, but the spikes of Mountain Maple are erect, whereas those of Striped Maple are drooping.


Host plant for various moth species including Serviceberry Leafroller Moth, American Dagger Moth, and Banded Tussock Moth (Database of World's Lepidopteran Host Plants; Gilligan, Wright, & Gibson, 2008).

There are 20 records in the project database.
