Acer × Norwegian Sunset™
Common name: 
Norwegian Sunset Maple
Sapindaceae, Aceraceae
Native to (or naturalized in) Oregon: 
  • Deciduous tree, 35 ft (10.7 m) tall and 25 ft (7.6 m) wide, upright oval shape.  Leaves intermediate in appearance between its parents, to about 25 cm long × 20 cm wide, 5-7 lobes, basal lobes pointed outward, glossy dark green above, lighter below; fall color from yellow-orange to red.  Fruit (samaras) 4-5 cm long, forming about a 130° angle, the seeds are viable.
  • Sun to part shade, more heat and drought tolerant than a Norway Maple.
  • Hardy to USDA Zone 4b         Developed by Keith Warren at J. Frank Schmidt Nursery, Boring, Oregon, and introduced in 1989, a cross of Acer truncatum × Acer platanoides (P.P. 7,529).  Its name reflects the similarity of the tree to a Norway Maple (A. platanoides), in growth rate, branch structure, and leaf shape.  A related cultivar, Pacific Sunset™, in comparison to Norwegian Sunset™, has a finer branch structure, is more spreading, and slightly brighter fall color.
  • Oregon State Univ. campus: along the east edge of the parking lot east of the Radiation Center (along Jefferson Way).
