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.
