About
Acer obtusifolium is a semi-evergreen tree that can reach heights of over 8 meters. Its leaves are leathery and may be simple or shallowly divided into three lobes, displaying a dark green hue and often curling slightly downward at the edges. In spring, it produces clusters of small yellow-green flowers, which are succeeded by tan winged seeds that may have a reddish-pink tint.
