Parkway Norway Maple

Parkway® is the marketed name for the Norway maple selection *Acer platanoides* ‘Columnarbroad’. It forms an oval crown with a strong central leader, dark green leaves, and yellow autumn color. Its upright branching gives the tree a structured outline, though it still needs generous room at maturity. ## Landscape use and size Oregon State University lists Parkway® at about 40 feet tall by 25 feet wide, with an oval form, a good central leader, and yellow fall color ([Landscape Plants](https://landscapeplants.oregonstate.edu/plants/acer-platanoides)). Use it along broad verges, boulevards, or in a large garden rather than a narrow planting strip. ## Siting and seasonal interest Full sun supports a dense crown; Norway maple also grows in partial shade. The species prefers moist but well-drained soil and bears yellow flowers in spring before its winged seeds develop ([RHS species profile](https://www.rhs.org.uk/plants/246/acer-platanoides/details)). The USDA Risk Management Agency lists ‘Columnarbroad’ (Parkway®) with minimum field-grown hardiness zone 3 ([eligible plant list](https://www.rma.usda.gov/legacy/tools/eplpps/2009/CTBK2009.pdf)). Parkway® is the trade name associated with cultivar ‘Columnarbroad’, a broader and faster-growing form than ‘Columnare’ ([Trees and Shrubs Online](https://www.treesandshrubsonline.org/articles/acer/acer-platanoides/)). ## Maintenance Water during establishment and extended dry weather. Prune selectively for structure when needed and allow clearance for surface roots. Norway maple seedlings can spread beyond planted sites in parts of North America, so check regional planting guidance before specifying it ([Oregon State University](https://landscapeplants.oregonstate.edu/plants/acer-platanoides)).
