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.
This species is native to the Chicago region according to Swink and Wilhelm's Plants of the Chicago Region, with updates made according to current research.

Tree & Plant Care
Chlorosis symptoms (pale green leaves with dark green veins) can be a problem in high pH soil and drought conditions.
Maples are considered 'bleeders' and are best pruned in early winter or during summer.
Red maple does not tolerate heavy pollution.
Disease, pests, and problems
Verticillium wilt (fungus) is a potential problem for maples; maple bladder gall, leaf hoppers.
Disease, pest, and problem resistance
Tolerant of wet sites and black walnut toxicity

Fruit are winged seeds in pairs (samaras), about 1 to 2 inches long, ripening in spring.
Color can be red to brown.
Cultivars and their differences

Cultivars are plants produced in cultivation by selective breeding or via vegetative propagation from wild plants identified to have desirable traits.
