Crimson King Norway Maple

Crimson King Norway Maple (Acer platanoides 'Crimson King')

Crimson King Norway Maple (Acer platanoides 'Crimson King') is a bold, large-scale shade tree prized for its deep burgundy-purple foliage that holds its color from spring through fall. Introduced in the 1940s, this cultivar remains a favorite for urban and suburban landscapes thanks to its stately presence, adaptability, and striking color contrast. Its broad, rounded canopy provides dense shade, making it an excellent choice for lawns, streetscapes, or as a dramatic focal point in expansive settings.

Distinctive Features

'Crimson King' stands out with its glossy, maroon-purple leaves that retain their rich tone even during the hottest months.

The tree typically reaches 35 to 45 feet in height and spreads 25 to 30 feet wide, forming a dense, symmetrical crown. In spring, it produces small yellow flowers before the leaves fully emerge, adding a subtle seasonal layer of interest.
