Emerald Lustre® Norway Maple

Emerald Lustre® is the marketed name for the Norway maple selection *Acer platanoides* ‘Pond’. It develops a rounded, upright-spreading crown with abundant early branching; medium-green leaves turn yellow in autumn. Published mature-size estimates differ, so allow ample room for its canopy. ## Landscape use and form J. Frank Schmidt lists the selection at about 45 feet tall by 40 feet wide and describes its rounded form and heavy early branching ([breeder profile](https://jfschmidt.com/all-trees/emerald-lustre-maple/)). The Botanic Gardens and State Herbarium of South Australia lists 8–12 m tall by 8–10 m wide for its ‘Pond Emerald Lustre’ entry ([Plant Selector +](https://plantselector.botanicgardens.sa.gov.au/Plants/Details/1045)). Use it as a shade tree in parks, large yards, or broad verges rather than a confined strip. ## Siting and seasonal interest Plant in full sun or part shade in moist, well-drained soil; the South Australian entry lists clay, loam, and sand. The foliage is medium green and turns yellow in fall. Norway maples typically flower on bare branches in spring, followed by winged seeds ([RHS species profile](https://www.rhs.org.uk/plants/246/acer-platanoides/details)). J. Frank Schmidt identifies the cultivar as ‘Pond’; *Emerald Lustre®* is the marketed name. USPP4837P was published in 1982; Google Patents labels its status expired-lifetime but cautions that the status is assumed ([patent record](https://patents.google.com/patent/USPP4837)). ## Maintenance Water during establishment and prolonged dry periods, and preserve clearance for mature roots and crown. In parts of North America, Norway maple can naturalize; check local planting guidance before specifying it ([Oregon State University](https://landscapeplants.oregonstate.edu/plants/acer-platanoides)).
