Facts About This Tree:
1. Red maple grows 20-30m tall (tallest recorded is 43m) and 40-90cm wide in trunk diameter, and lives 100-150 years.
2. Its foliage turns every shade of red imaginable – sometimes so brilliant it affects the eyes like dayglow.
3. They often hybridize with silver maple which results in intermediate forms.
4. Red maple has been traditionally underutilized compared to its big brother, sugar maple. Red maple wood is not as heavy, hard, or strong as sugar maple, but it is often substituted for sugar maple where these qualities are not critical.
5. Moose, deer, rabbits, and hares eat the twigs, porcupines and beavers gnaw on the bark, and chipmunks and gray squirrels consume the seeds.
