The Crimson King is a Norway Maple (Acer palinodes ‘Crimson King’) and not a red maple. It contrasts well with other green-leaf maples and other deciduous trees and is often used as a specimen in a residential front or back yard. It transplants relatively easily, but we have found that after planting, the tree grows quite slowly for the first two to four years - then it will grow faster after it establishes.
There are upright forms of Crimson King Maple that can be used in areas of limited space or can be grown as a street tree. ‘Schwedler’ maple is a Norway Maple that has purple leaves (similar to Crimson King) in the spring. In the mid-summer the leaves gradually fade to a purple-green to almost green in the late summer. Debra Maple is a more recently improved variety of the ‘Schwedler’ maple.
Other red-leaf trees such as Frost Birch and Royal Frost Birch are red-leaf birch trees that have a creamy white bark. They can be grown as a clump or grown as a single stem tree. Blood Good Japanese Maple and red-leaf birch can produce shade, but not nearly as much as the Crimson King Maple. Royalty Flowering Crab has purple-red leaves with small crab apple fruit that persists well into the winter.
