Emerald Queen™ Norway Maple

Emerald Queen™ is a vigorous Norway maple with a dense oval crown and upright-spreading branches. Its leaves emerge with a reddish tint, mature deep green, and turn yellow in autumn; greenish-yellow flowers appear in spring. ## Landscape use and mature size J. Frank Schmidt lists a mature size of about 50 feet tall by 40 feet wide ([breeder profile](https://jfschmidt.com/all-trees/trees/emerald-queen-maple/)). The University of Florida IFAS gives a broader estimate of 60–70 feet tall by 35–40 feet wide, showing that dimensions vary with site and growing conditions ([IFAS profile](https://ask.ifas.ufl.edu/publication/ST033)). Allow substantial room for the crown and shallow roots, especially near lawns and paving. ## Siting and seasonal interest Grow in full sun or partial shade in moist, well-drained soil; the RHS also lists chalk, clay, loam, and sand. Spring brings small greenish-yellow flowers, followed by winged fruit; the leaves are deep green through summer and yellow in fall ([RHS](https://www.rhs.org.uk/plants/64076/acer-platanoides-emerald-queen/details); [J. Frank Schmidt](https://jfschmidt.com/all-trees/trees/emerald-queen-maple/)). This large tree suits parks, broad verges, and spacious gardens rather than narrow planting strips. ## Maintenance Water while the tree establishes and during extended dry weather. Its shallow roots may compete with lawn grasses or lift nearby paving, so plan the planting distance carefully. Norway maple can produce abundant seedlings outside its native range; check local planting guidance before specifying it ([University of Florida IFAS](https://ask.ifas.ufl.edu/publication/ST033); [Oregon State University](https://landscapeplants.oregonstate.edu/plants/acer-platanoides)).
