Content Detail

Norway maples have invasive traits that enable them to spread aggressively. While these trees have demonstrated invasive traits, there is insufficient supporting research to declare them so pervasive that they cannot be recommended for any planting sites. Review of risks should be undertaken before selecting these trees for planting sites. Norway maple is known for its tolerance of urban conditions, but it often becomes a weedy plant through self-seeding.

Size and form:

Norway maple will grow to 40-50 feet tall and 35-50 feet wide.

Native geographic location and habitat:

It is native to Europe.

Bark color and texture:

The bark is gray and fairly tightly ridged and furrowed.

Leaf description:

Norway maple has simple leaves in pairs (opposite) that are three to six inches long. Leaves are slightly broader than those of sugar maple. The five lobed leaves are dark green in summer. Fall color can range from yellow-green to yellow.

Flower description:

Small, pale yellow flowers appear in upright, rounded clusters. Although inconspicuous by themselves, they are very showy when the whole tree is in flower.

Fruit description:

The fruit are winged seeds in pairs or samaras. Each wing is one to two inches long and the two wings are spread at a wide angle. They start off as green and mature to brown.

Plant care:

Avoid pruning in early spring as maples are ‘bleeders’ and will lose large amounts of sap. Norway maple is adapted to a wide range of soils and environments and is pollution tolerant.

List of pests, diseases and tolerances:

Norway maple is prone to girdling root and tends to self sow and become weedy. Verticillium wilt is a potential serious problem. Anthracnose is a common leaf disease. Tar spot is becoming very common on this species.
