Red Maple

Acer rubrum

One of the most widespread trees on the East Coast, native across the eastern United States, red maple gets its name from the red twigs. buds, flowers, and fruit it develops in the spring and spectacular leaf colors of the orange-red palette it produces in the fall. Red maples flower in April, before their leaves come out. The fruits promptly ripen by the time the leaves grow the full size at the end of May. The leaves have three main lobes and sometimes two additional smaller lobes. The bark on the youngest twigs is dark red, then becoming pale gray. Mature bark darkens to nearly black, often exfoliating, its structure very variable. Red maple is a rather tall (to 40-60 ft), fast-growing, adaptable tree that can grow in wide range of environments, although its prime habitats are wetlands. Here it often becomes a forest-forming tree, producing the signature plant communities: red maple swamps. The tree is very tolerant of flooding, although it can grow quite abundantly in drier habitats. Its intensive seedling production along with dense root system often makes it difficult for other plants to compete. Red maple is sometimes exploited for maple syrup, though only on a small scale, as it does not produce as much syrup as sugar maple. New England becomes so attractive for tourists during the fall largely due to the performance staged here by red maples.
