Red maple is a widely adaptable large tree common to the woods of eastern North America. A red tinge can be found in its flowers, twigs, and seeds, but it is most notable for the scarlet of its leaves in fall. Red maple needs plenty of room for its dense, spreading root system. Fall color can be yellow rather than red, so select a cultivar bred for red fall color.
