Norway Maple(Acer platanoides) –

The Norway maple has been widely planted in urban areas all over the U.S. It’s a medium-sized deciduous shade tree grows 40-50 ft tall with a symmetrical, dense, rounded canopy. Leaves (7” across) have five sharply pointed lobes and bear a striking resemblance to those of sugar maple. Leaf stems will ooze a milky sap when cut. Fall color is usually yellow. Small yellow flowers in erect corymbs (clusters) will appear in the spring before the foliage buds out. After the flowers are spent, they give way to paired seeds with outward spreading wings (samaras to 2” long).

 

Red Maple (Acer rubrum) –

 The red maple is a medium-sized deciduous tree that grows 40-60 ft tall with an oval to rounded crown. Red maples will grow faster than Norway and sugar maples, but much slower than a silver maple. Emerging twigs, leafstalks, new growth leaves, flowers, fruit and fall color all are red or are tinged with red. The quality of the red fall color is variable; all depending on how the weather is in the fall. Leaves (2-5" long) have 3 pronounce triangular lobes (occasionally 5 lobes with the two lower lobes being largely repressed). Medium to dark green leaves have pointed tips and toothed margins; a dull green can be seen if looking up under the canopy. Flowers can be male or female (monoecious) and will appear in late winter to early spring (March-April) before the leaves emerge. Fruits are two-winged samara.

 

Sugar Maple (Acer saccharum) –

The sugar maple is a deciduous tree tall with a dense, rounded crown which will usually grow 40- 80 ft. Medium green leaves (3-6" wide with 3-5 lobes) will turn brilliant yellow-orange in fall, sometimes the color can vary immensely; it all depends on the weather in Autumn. The fruit is the unmistakable maple two-winged samara. Sugar maples are slow growing, long lived trees; they will however grow moderately for the first 30-35 years.

 

 

Sycamore Maple (Acer pseudoplatanus) –

Sycamore maple or planetree maple is a round, spreading, deciduous tree that grows 40-60 ft tall. Leathery, 5-lobed, dark green leaves (6” across) are dull green beneath with prominent veins and coarsely toothed margins. Leaves don’t produce fall color. Yellowish green flowers appear in panicles (5” long) in the spring after the foliage emerges. Pairs of samaras (2” long) with the wings forming a 60-degree angle follow the flowers. The samaras will mature in early fall. Bark on mature trunks will peel off to expose its inner orange bark.
