Amur maple can be distinguished by its reddish-brown buds. Its leaves are 3 lobed, have serrated margins, and are a dark green color in the summer turning orange, red, and yellow in the fall. Fragrant yellow-white flowers are produced in the early spring and red to brown paired samaras form in late summer and are dispersed by the wind. One tree can produce up to 5,000 samaras, displacing native shrubs and trees. The bark is gray and smooth on younger trees, turning fissured or striped with age.
