Description

The Red Maple is one of the most abundant and widespread trees in eastern North America. Known for its brilliant red autumn foliage, it features a medium to large deciduous canopy, smooth grey bark on younger trees that becomes ridged and scaly with age, small red flowers appearing in early spring before the leaves, and winged samaras (helicopter seeds) in late spring.

Habitat

Typically found in moist woods, swamps, bottomlands, and along streams, though highly adaptable to various upland sites and well-drained soils in full sun to partial shade.

Native Range

Native to eastern and central North America, extending from eastern Canada south to Florida and west to Texas and Minnesota.
