About
Acer mandshuricum is a deciduous shrub or small tree that typically reaches heights of 6 to 7 meters. It features broad, green leaves with a lighter underside, each leaf made up of three leaflets. The young foliage has a rusty-red hue and is borne on red stems, transitioning to a vibrant red in the fall. In spring, the plant produces subtle greenish-yellow flowers, which can give way to winged, purple-brown fruits.
