Good choice for columnar growth. Nice yellow fall color. Leaves stay on the tree well into the fall before changing color. Mid-Late October. Zone 3b hardy. Increasingly becoming popular in Edmonton, AB.

Columnar form may have use in select urban settings where horizontal space limitations are necessary.

Norway maples do not mature well in the midwest. Nearly every mature city Norway has a twisted trunk with a visible split twisting from root to crown. Does not age gracefully.

Was popular for its pollution tolerance in urban settings, but is being phased out from the list of elligible species for planting in many cities.

Reseeds like crazy and may have been listed as invasive in some east coast areas. Definately wreaking havoc in New England's Sugar Maple forests.

Please reconsider before planting this European species near naturalized, native, rural, or protected areas.
