Gardeners' Notes:

This cultivar is very similar to the older cultivar of Schwedler Maple. Its foliage is reddish-purple in spring and then turns reddish-green until it gets yellow for autumn color. It is supposed to have a straighter growing form with an upright crown. I have hardly ever seen it. I mostly see either Crimson King or Schwedler. The mother green species has become a major invasive European plant in much of the eastern and Midwestern USA; I am not sure if this cultivar really does that too. I don't think it comes true from seed. Check out the straight species in these Files.

A cultivar of the common urban weed tree. It requires vigilant monitoring and pruning to maintain the leaf color, which reverts to the species.

This tree becomes a pest through self-sowing. (The leaf color isn't inherited.) The thirsty roots make it hard to grow other plants around it.

Planting is prohibited in Massachusetts and Connecticut. This tree invades and impoverishes natural habitat in eastern North America and the Pacific Northwest.

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.
