Red Maple is a handsome shade tree, named for its often red autumn leaf display. It has the greatest north-south distribution of all tree species along the East Coast, ranging from eastern Canada south to Florida and west to east Texas. Infrequent in forest; mostly found as understory. Very tolerant of most soils, but prefers slightly acid, moist conditions; tolerant of ozone and intermediately tolerant of sulphur dioxide. Not particularly urban tolerant, although planted in ever-increasing numbers in cities (Dirr 1998). Red maple is less reliably symmetrical than the hard maples. Medium to large tree with narrow or rounded, compact crown and red flowers, fruit, leafstalks, and autumn foliage. This popular ornamental tree grows 40-60 ft. in cultivation, occasionally reaching 100 ft. in the wild. Leaves vary from 3- to 5-lobed, with lobes separated by V-shaped angles. Male trees have notable pinkish red flowers in early spring, and females display decorative red samaras soon after. Young, vigorous trees have smooth, silvery gray bark which provides winter interest. Roots in a dense, fibrous network, often preventing other plants from growing near its trunk. Fall foliage is quite variable, ranging from the brilliant red for which the species is known, to yellow or greenish-yellow.
