Miyabe Maple - Acer miyabei
These four Miyabe Maples at the Morton Arboretum were started from seed in 1932.  Accession 550-32*12

Miyabe Maple is an outstanding specimen tree, featuring crisp, dark green summer foliage, and an appealing upright rounded habit with a wide crown. This tree likes full sun and grows best in moist, well-drained soils. Tolerant of mild drought, prefers slightly acid soil. Relatively short-lived fall color is a spectacular, vibrant butter-yellow to golden-yellow, depending on temperature changes and site conditions. [1]

Miyabe Maple: Habit
This lovely Miyabe provides a wonderful retreat from a hot, sunny summer day.

Chicagoland Grows, a partnership between the Chicago Botanic Garden and The Morton Arboretum,  reports a cultivar of the Miyabe, trade name 'State Street', is a cold-hardy alternative to hedge maple, A. campestre, and more resitant to heat and drought than Norway Maple.
