Acer saccharum, the sugar maple or rock maple, is a species of maple native to the hardwood forests of eastern Canada. Sugar maple is best known for its bright fall foliage and for being the primary source of maple syrup.
Acer saccharum is a deciduous tree normally reaching heights of 25–35 m, and exceptionally up to 45 m. A 10-year-old tree is typically about 5 m (16 ft) tall. When healthy, the sugar maple can live for over 400 years.
The leaves are deciduous, up to 20 cm (7.9 in) long and equally wide, with five palmate lobes. The autumn colour is often spectacular, ranging from bright yellow on some trees through orange to fluorescent red-orange on others. Sugar maples also have a tendency to colour unevenly in autumn. In some trees, all colours above can be seen at the same time. They also share a tendency with red maples for certain parts of a mature tree to change colour weeks ahead of or behind the remainder of the tree.
