NATIVE RANGE AND HABITAT
Paperbark maple is native to central China. Trees grow in moist, sheltered sites. It was introduced into cultivation by Veitch in 1901.
Not native to Kentucky.
Growth Habit and Form
Paperbark maple is a small, deciduous tree with a neat, compact shape. Trees typically grow 20 to 30 feet in height with a spread equal to height. The trunk is short and the canopy oval or rounded.
The blunt, toothed leaves are opposite and trifoliate (comprised of three leaflets). Leaflets are dark green above with paler hairy undersides. Paperbark maple displays excellent fall color. Leaves turn an array of bright red and orange colors in the fall.
Flowers are green, small and inconspicuous; they bloom in spring.
Fruit is a pair of winged seeds called samaras. Each samara is less than 2 in. long. The fruits ripen in the fall and are scattered by wind.
The bark is brown to reddish brown and peels away to reveal new rich, cinnamon colored bark. Exquisite bark character develops early as second year wood usually exfoliates. The bark of this tree is one of the most decorative barks of any maple tree.
