Acer saccharum

Sugar maple

Nom français: Érable à sucre

LEAVES – Opposite, glabrous (without hairs), simple leaves, palmate with 3-5 sharp-pointed lobes with few teeth. The interior of the notches of the lobes are rounded (U-shaped), in contrast with the silver and red maples who have angular notches (V-shaped).
BARK – Smooth and grey on young trees, fissuring and chiping into uneven stripes on old trees.
FRUITS – The fruit is a pair of samaras (winged seeds). The angle between the two wings is a characteristic that can help differentiating the maples.
TWIGS – slender with long pointy brown-colored buds.

Tall tree reaching 40m high. It tolerates shade, which means it can grow in old forests and often forms pure stands. It grows in southern Québec and northeastern US. It is best known for being the primary source of maple syrup that is produced from its sap and for its brightly colored fall foliage, which ranges from bright yellow to orange-red. The sugar maple is sometimes confused with the Norway maple, which is not native to America but has been commonly planted in cities and suburbs. They can easily be distinguished by looking at their buds (sugar: brown and sharp; Norway: green or reddish purple and blunt) or the sap in the leaf petiole (sugar: clear; Norway: white).
