Norway Maple Crimson King An intensely coloured seedling variety of the Norway maple, Acer platanoides Crimson King is a medium-sized to tall deciduous tree with deep purple-crimson, glossy, five-lobed leaves. Pinkish-orange flowers on the leafless branches in April turn to double-winged, sycamore-like fruit (samaras) in Autumn. A vigorous, fairly fast-growing tree with a symmetrical spreading shape, it is very hardy and wind-resistant, and a good choice for colder areas. It also tolerates city pollution.
