Botanical Name

ACER rubrum 'Red Sunset'

Plant Common Name

Northern Red Maple, Red Maple

General Description

Red Sunset red maple is a very popular shade tree with its glossy green, lobed leaves that reliably change orange and red each fall. This tall, deciduous tree is pyramidal in form when young, but becomes upright and rounded at maturity. The red flowers appear on the red twig ends in early spring. Its samaras, or two-winged seeds, are often reddish in color.

North American in origin, 'Red Sunset' is adapted to a wide range of soil types and topographies, including wet sites. Acidic soil tends to intensify the red fall foliage coloring. Red maple grows best in locations with full to part sun. It is widely planted, and makes a great shade tree or street tree for urban settings. Since this species is known for having surface roots, avoid planting too closely to sidewalks.
