Acer platanoides 'Crimson King'

Crimson King Norway Maple

Acer platanoides ‘Crimson King’ is a classic purple-leaved Norway maple valued for its deep maroon foliage, dense canopy, and strong urban tolerance. Leaves emerge rich burgundy-purple in spring, retain dark color well through summer, and shift to bronze-red tones in fall.

The tree develops a broad, rounded crown with sturdy branching and a strong central leader, providing dense shade. Its bold foliage color makes it a dramatic focal point and a strong contrast to green-leaved trees.

‘Crimson King’ thrives in full sun to partial shade and adapts well to a wide range of soils, including clay and compacted urban soils, as long as drainage is adequate. It tolerates heat, wind, pollution, and road salt and is hardy in USDA Zones 4–7.
