Description The cultivar Emerald Queen is generally considered one of the most urban tolerant of the different Norway maple cultivars.

This large deciduous shade tree grows to a height of 60’-70’, with a width of 35’-40’. It features a dense oval canopy. It bears simple leaves which are up to 7” across. They are set opposite from one another. Leaves are star-shaped and have 5 prominent sharp lobes. Leaf veination is classified as palmate. During the summer the leaves are green but in the fall they turn a brilliant yellow before they are shed for the winter.

Bloom occurs in April before the leaves emerge. The flowers are greenish yellow. Flowers give rise to winged samaras (up to 1 1/2” long) which can spread well out from underneath the canopy.

This species prefers full sun, but can take partial shade.

No serious insect or disease problems. In the Pacific Northwest Verticillium wilt is not a major problem.
