Acer State Street®
From the Chicagoland Grows® Collection, we bring you a uniformly branched, deciduous shade tree with ascending branches and a uniform upright oval habit, maturing to a more rounded upright habit with age. Found in the collections of The Morton Arboretum, the satin-surfaced, lobed leaves are a medium to dark green and are tatter resistant in high winds due to its heavy leaf substance. The leaves change quickly in fall to a pale golden hue similar to that of Ginkgo. This is a uniformly growing tree, making it an excellent shade tree. As the tree matures, the corky gray-and-tan bark becomes more ridged and fissured, adding to its display value. State Street™ has exceptional tolerance to urban pollution, heat, cold, and acidic or alkaline soil, and is drought tolerant once established. Easy to transplant and grow, and long-lived, it rarely needs corrective pruning thanks to its uniform growth habit. ts excellent ornamental attributes, site adaptability, and stress tolerance provides for a broad range of landscape applications in commercial, residential, and urban sites alike. Use it as a medium-to-large street tree, and in parks and residential yards as a shade tree. State Street™ is a more cold-hardy alternative to hedge maple (Acer campestre) in northern growing conditions, and is a noninvasive, and more heat- and drought-resistant alternative to Norway maple (A. platanoides). Consider it as a replacement tree for native ash trees (Fraxinus spp.) in areas infested with emerald ash borer. It can also be used as a stronger-wooded substitute for silver maple (A. saccharinum), and as a red maple (A. rubrum) and sugar maple (A. saccharum) substitute in areas where alkaline soils can induce problems with chlorosis. Awards: 2011 recipient of the Woody Ornamental Plant of the Year award, Wisconsin Nursery Association, and 2011 recipient of the Plant of Merit® (Missouri Botanical Garden) designation as an outstanding plant for the lower Midwest.
