Amur maple can be grown either as a small, upright spreading tree with a dense, rounded crown or a large multi-stemmed shrub, reaching 15-20 feet tall at maturity. A native of northern Asia, it is hardy to zone 2. The glossy green leaves are smaller than most maples, divided into three sharply pointed lobes. In early spring, it produces clusters of fragrant, dainty creamy-white flowers. In late summer, an abundance of winged seeds called "samaras" may litter the lawn and sprout. It is easy to grow in moist, rich, well-drained soils in full sun to part shade and performs well in areas with cool summer climates. Amur maple makes an unusual specimen tree or shrub; its light green leaves turn rich crimson underlain with orange in the fall. Unfortunately, the cooler climate of northeastern North America is so suitable to this species that is has become invasive in some areas, including Illinois.
