Acer rubrum
Overview
The Red Maple is one of the most widespread and adaptable tree species in eastern North America. Known for its brilliant red flowers, twigs, and fall foliage, it provides year-round interest and is often among the first trees to signal the arrival of spring and autumn.
Native throughout the Appalachian region, Red Maple thrives in a wide range of habitats, from wetlands and floodplains to upland forests and urban landscapes. Its adaptability, attractive appearance, and moderate growth rate have made it one of the most commonly planted shade trees in the United States.
Identification

- Develops shallow ridges and scaly plates with age
- Darkens to gray-brown on mature trees
Flowers
- Small red flowers that appear in late winter or early spring
- One of the first native trees to bloom each year
- Flowers emerge before or with the leaves
Fruit
- Winged seeds known as samaras
- Typically red when immature
- Produced in pairs and dispersed by wind in spring

Native Range
Red Maple is native to eastern North America and occurs naturally throughout the Appalachian region, including West Virginia, Ohio, and Kentucky. It is remarkably adaptable and can be found in swamps, floodplains, stream corridors, upland forests, and urban environments.
Its ability to tolerate both wet and moderately dry conditions has contributed to its success across a broad geographic range.
Ecology and Wildlife Value
Red Maple provides important ecological benefits throughout its range. Its early spring flowers offer nectar and pollen for bees and other pollinators at a time when few other trees are in bloom.
Birds and small mammals consume the seeds, while the canopy provides nesting sites and cover for wildlife. The species also serves as a host plant for numerous native insects, supporting healthy forest and urban ecosystems.
As a shade tree, Red Maple helps reduce urban heat, improve air quality, and intercept stormwater runoff.
Human Uses and Cultural Significance
Because of its adaptability and attractive appearance, Red Maple is widely planted as a landscape and street tree. It is particularly valued for its reliable fall color and ability to thrive under a variety of growing conditions.
The wood is commonly used for:
- Furniture
- Flooring
- Pallets
- Veneer
- Boxes and crates
- Pulp and paper products
Red Maple also contributes to maple syrup production, although Sugar Maple remains the preferred species for commercial syrup production.
Red Maple at Marshall University
Red Maples contribute seasonal beauty and ecological value to the Marshall University Arboretum. Their spring flowers, summer shade, and vibrant autumn colors make them easily recognizable features of the campus landscape.
As one of the region’s most adaptable native trees, Red Maple demonstrates the resilience and diversity of Appalachian forests while providing year-round interest for students, faculty, staff, and visitors.
