Acer saccharum is a large, fast growing, deciduous tree. Its mid green leaves are opposite, palmate with entire margins, has five lobes and are up to 12cm long and 12cm wide. Before the leaves fall in autumn they turn yellow/ orange/ deep red. Its bark is grey/ brown with a rough texture and deeply furrowed with age. Its small yellow/ green flowers are corymbs,  and appear before the leaves. Its fruit is a samara, two winged seed.

In its native habitat it is found in woodlands and often forms single species stands. It is the primary source of Maple syrup. A red leaf of this tree features on the Canadian flag.
