Wide branches that sweep low to the ground and deeply furrowed, corky bark are among the charms of this densely branched shade tree. Though Miyabe’s maple is listed as endangered in its native habitat in Japan, several cultivars are considered hardy, adaptable urban street trees. The dark green leaves turn golden in fall.
This plant has some cultivated varieties. Go to list of cultivars.

Cultivars and their differences
State Street® (Acer miyabei ‘Morton’): Grows 35 to 50 feet tall with a uniform, oval to rounded shape. It has shown excellent heat and drought tolerance, as well as tolerance of alkaline soils. The thick, 5-lobed, attractive medium to dark green leaves remain long into fall, then rapidly change to a pale golden-yellow fall color. The parent tree was selected from the collections at The Morton Arboretum. A Chicagoland Grows® introduction.
