About
Acer forrestii is a spreading tree that can reach heights of up to 10 meters. Its branches have an arching form and are initially red, transitioning to green with distinctive white stripes as they mature. The wide, three-lobed leaves emerge with a reddish hue, shifting to a dark green during the summer months and displaying orange-red tones in the fall. In spring, the tree produces clusters of small flowers that are red and green, which are followed by two-winged fruit that is green and pink in color.
About the genus
