Sugar maple grows from Nova Scotia and New Brunswick westward to Ontario and Manitoba, southward through Minnesota, and eastern Kansas into northeastern Texas. It extends eastward to Georgia and northward through the Appalachian Mountains into New England. Local populations occur in northwestern South Carolina, northern Georgia, and northeastern South Dakota. Disjunct populations are known from the Wichita Mountains of southwestern Oklahoma.
This plant is present in at least 39 states/provinces in this country.
Sugar maple is a deciduous tree which reaches 90 to 120 feet (27-37 m) in height and 30 to 36 inches (76-91 cm) in d.b.h. Extremely large specimens have reached more than 130 feet (40 m) in height and more than 5 feet (1.5 m) in d.b.h. Sugar maple is long-lived and plants can survive for 300 to 400 years. The bark is light gray to gray-brown and becomes deeply furrowed and rough with age. Twigs are a shiny, reddish-brown. Sugar maple is relatively deep-rooted, with many extensively-branched laterals.
Sugar maple is monoecious or dioecious. Small, greenish-yellow flowers are borne in tassel-like clusters or racemes. Each drooping cluster contains 8 to 14 flowers. The fruit is a paired, papery-winged samara which averages 1 inch (2.5 cm) in length.
Growth initiation of sugar maple varies geographically. Flower buds generally begin to swell prior to the development of vegetative buds and generally emerge 1 to 2 weeks before the leaves appear. Male and female flowers mature at slightly different rates, which promotes cross-pollination. Fruit ripens approximately 12 to 16 weeks after the flowers appear. Fruit begins to fall approximately 2 weeks after ripening.
