Anyone who thinks Norway maple (Acer platanoides) is still just a street tree in the U.S. should check out Massachusetts right now. The Norways can easily be spotted because of their flower clusters, which form a sickly green aura around the branches (one commenter calls it chartreuse but I am not feeling that kind). Over the decades, Norway maples have managed to find their way not only into suburban wooded areas, but also into true deciduous forests, where they have been shown to inhibit the regeneration of the native forest canopy.
