Distinguishing Feature

Historical Fact

Red maple is a pioneer species, often one of the first tree species to grow in disturbed areas, helping forests regenerate and shape woodland structure. It can also grow to impressive sizes, with some individuals reaching over 140 feet tall, making it one of the most striking native trees in eastern North America.

Why We Love It

With its brilliant red flowers, seeds, twigs, buds and fall foliage, the red maple is not only the ultimate Valentine’s tree but it also provides year-round colour and interest, making it a standout tree for any yard or community planting.

Did You Know?

Red maple is one of the most widespread native maples in eastern North America.
Its canopy provides shelter, while its flowers, seeds, buds and twigs offer year-round food for birds, small mammals and pollinators.
It can be tapped for its sap to make syrup, which is lighter and more delicate in flavor than the rich, robust taste of sugar maple syrup.
