“Acer pseudoplatanus Negennia is a vigorous, large and conical cultivar. It was selected in the late 1940s in the Netherlands where it is widely used as a street tree. It has dark green, red stalked leaves. Tolerating air pollution, Acer pseudoplatanus Negennia thrives in most soils and is particularly useful for coastal sites where it can make an effective defence against strong winds and salt-laden air. Like many clones, as it matures it represents a model shape and form of its seedling parent.”
