Description A native of Europe, Norway maple is now one of the most widely planted urban shade trees in the entire United States.

  Morphology:
Crimson King is considered a medium-sized deciduous shade tree typically growing 40-50’ tall with a dense, symmetrical, rounded crown. It has very large leaves (up to 7” across) with five sharply pointed lobes (sugar maple has rounded points). If the stems are cut they will exude a milky sap.

  Adaptation:
'Crimson King' is generally considered one of the best red-leaved Norway maple cultivars. The intense maroon color lasts all season long. Fall color is not as good as 'Crimson Queen'.

  Pests:
Problems include powdery mildew, aphids and surface rooting, especially in lawn situations.
