Amur Maple

Acer ginnala

Summary 6

Acer ginnala (Amur maple) is a plant species with woody stems native to northeastern Asia from easternmost Mongolia east to Korea and Japan, and north to the Russian Far East in the Amur River valley. It is a small maple with deciduous leaves that is sometimes grown as a garden subject or boulevard tree. It is considered invasive in some parts of North America.

Acer ginnala is a deciduous spreading shrub or small tree growing to 9–32 ft tall, with a short trunk up to 8–16 in diameter and slender branches. The bark is thin, dull gray-brown, and smooth at first but becoming shallowly fissured on old plants. The leaves are opposite and simple, 1+1⁄2 – 4 in long and 1+1⁄4 – 2+1⁄4 in wide, deeply palmately lobed with three or five lobes, of which two small basal lobes (sometimes absent) and three larger apical lobes; the lobes are coarsely and irregularly toothed, and the upper leaf surface glossy. The leaves turn brilliant orange to red in autumn, and are on slender, often pink-tinged, petioles 1+1⁄4 – 2 in long.
