Plant Common Name

Maple, Norwegian Sunset™ Maple

General Description

Norwegian Sunset maple is a rapidly growing, uniformly branched deciduous tree discovered as a chance seedling in a bed of Shantung maples (Acer truncatum) in Oregon. Its upright oval habit resembles that of its other suspected parent, Norway maple (Acer platanoides). This straight-trunked hybrid has glossy dark green five- to seven-lobed leaves that turn orange-red to red in fall. Small yellow flowers in spring give rise to winged green fertile fruit.

Plant this maple in full to part sun and well-drained moisture-retentive soil. This handsome tree looks best went planted as a specimen shade tree in an open lawn. It also makes a good small street tree.
