Mountain Maple
Acer spicatum

Description

Acer spicatum, or mountain maples, is native to Ontario and ranges throughout northeastern North America but are extremely rare in the nursery industry. A substitute that is more readily available at nurseries is the striped maple, also called moose maple (Acer pensylvanicum). Mountain maples are resistant to most diseases and insects but require protection from wind and sun but are relatively easy to transplant. The hardy, shade-adapted species can prevent erosion on streambanks and steep slopes. These small maples, with the most northerly range among maples, adapt to various soils and support wildlife such as rabbits, deer, moose, and ruffed grouse. Though important in riparian systems, they are not well-suited for cultivation.
