Everything about Acer Griseum totally explained
Acer griseum (
Paperbark Maple; ) is a species of
maple native to central
China, in the provinces of
Gansu,
Henan,
Hubei,
Hunan,
Shaanxi,
Shanxi, and
Sichuan, at altitudes of 1,500–2,000 m.
It is a small to medium-sized
deciduous tree, reaching 10-20 m tall with a trunk up to 70 cm diameter. The
bark is smooth, shiny orange-red, peeling in thin, papery layers; it may become fissured in old trees. The shoots are densely downy at first, this wearing off by the second or third year and the bark exfoliating by the third or fourth year. The
leaves are compound, with a 2–4 cm petiole with three
leaflets, each 3-10 cm long and 2-6 cm broad, dark green above, bright glaucous blue-green beneath, with several blunt teeth on the margins. The
flowers are
androdioecious, produced in small
corymbs in spring, the
fruit being a paired
samara with two winged
seeds about 1 cm long with a 3 cm wing.
Cultivation and uses
Paperbark Maple is widely grown as an
ornamental plant in temperate regions. It is admired for its decorative
exfoliating bark,
translucent pieces of which often stay attached to the branches until worn away. It also has spectacular autumn foliage which can include red, orange and pink tones.
It was introduced to cultivation in
Europe in 1901 by
Ernest Henry Wilson for the
Veitch Nurseries, and to
North America shortly after.
Recent attempts have been made to acquire new seed stock from wild populations in China because it's believed that the current gene pool of cultivated specimens is very small.
Propagation of
Acer griseum is somewhat difficult as seeds have the same
parthenocarpic tendencies as those of
Acer maximowiczianum.
