Acer × Norwegian Sunset™
Norwegian Sunset Maple
A. truncatum × A. platanoides Norwegian Sunset™
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. 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 is Pacific Sunset™, it, in comparison to Norwegian Sunset™, has a finer branch structure, is more spreading, and slightly brighter fall color.
