Additional Information

This cultivar is easy to transplant and is tolerant of different soils. The Columnar Norway Maple is more adaptable to drought than other Maples. Pollution tolerant. When Norway maple escapes cultivation and invades natural areas it reduces species richness and native tree regeneration by out-competing other trees and understory species for resources, creating dense shade canopies, and spreading rapidly through high seed production. It also releases toxins that reduce the growth and reproduction of native species.
