Natural range

Acer pensylvanicum (striped maple, also known as moosewood and moose maple) is a small North American species of maple.


It is a small deciduous tree growing to 5–10 meters (16–33 ft) tall, with a trunk up to 20 cm (8 in) in diameter.[2]

The young bark is striped with green and white, and when a little older, brown.[2]

The leaves are broad and soft, 8–15 cm (3–6 in) long and 6–12 cm (2.5–4.5 in) broad, with three shallow forward-pointing lobes.[2]

The fruit is a samara; the seeds are about 27 mm (1.1 in) long and 11 mm (0.43 in) broad, with a wing angle of 145° and a conspicuously veined pedicel.[2][3][4]

The spelling pensylvanicum is the one originally used by Linnaeus.


The natural range extends from Nova Scotia and the Gaspe Peninsula of Quebec, west to southern Ontario, Michigan, and Saskatchewan; south to northeastern Ohio, Pennsylvania, and New Jersey, and along the Appalachian Mountains as far south as northern Georgia.[5][6]

Moosewood is an understory tree of cool, moist forests, often preferring slopes. It is among the most shade-tolerant of deciduous trees, capable of germinating and persisting for years as a small understory shrub, then growing rapidly to its full height when a gap opens up. However, it does not grow high enough to become a canopy tree, and once the gap above it closes through succession, it responds by flowering and fruiting profusely, and to some degree spreading by vegetative reproduction.[7][8]
