‘Cinnamon Flake’ is similar to the parent species, but features bark that peels into smaller strips. The most widely available are ‘Cinnamon Flake’, ‘Fireburst’, and ‘Gingerbread’. Several cultivars have been derived from paperbark maple. It is vulnerable to Armillaria and Verticillium root rot, as well as aphids, and horse chestnut scale. Paperbark maple is resistant to most insects and disease pathogens. Paperbark maple can be pruned in fall or winter, after the tree has become dormant. This can be taxing on the tree, especially during extended periods of drought. Pruning should be avoided in spring, as the tree will weep sap. Maintenance pruning should be performed each year to strip out any dead or diseased branches. As such, extensive pruning is seldom required. The tree requires watering at least once a week, especially when drought is persistent. The roots are moderately susceptible to rotting when exposed to excess moisture. Paperbark maple develops a sturdy root system. It tolerates clay soils, and exhibits a moderate resistance to salt. It is most partial to moist, well-drained soils. It can be grown in average, slightly acidic, moist, clay, and well-drained soils. Paperbark maple prefers partial shade to full sun. Juvenile cuttings are preferred over woody cuttings, as the latter often have difficulty establishing roots. Propagation from cuttings is more efficient, but can also be challenging. Only about 5% of the seeds end up being viable.ĭue to its low viability rate, paperbark maple is notoriously difficult to propagate from seed. The seeds are disseminated by the wind to nearby locations, where they germinate in the soil, and take root. The seeds are larger than those produced by other maple trees. Each samara contains large seeds about 1 cm long. In summer, the blooms are shed, and give way to paired samaras, with two winged seeds. Pollinators are attracted to the blooms in spring and summer. Paperbark maple produces inconspicuous yellow blooms from April to early May. In fall, the leaves turn a range of colors: from shades of orange and red to reddish-green or brown-green. The upper leaf surface is dark green, while the lower leaf surface is blue-green to gray-green, and laden with fine hairs. Paperbark maple leaves are trifoliate each leaf features three coarsely toothed leaflets. The inner bark is tan to rose colored or brown. The outer bark has a copper orange to reddish-brown coloration. The bark begins exfoliating by the third or fourth year of the tree’s development. The curls will often remain attached to the tree. Paperbark maple has distinctly smooth bark that curls into large, papery layers. The trunk can measure up to 28 inches in circumference. It can reach 20 to 30 feet tall, with a 15 to 25 foot spread. Paperbark maple is a small to medium sized tree. Paperbark maple has a short life-span, living 40 to 150 years. Paperbark maple can be pruned in late fall or winter, when the plant is dormant. The branches formed by paperbark maple are slender, and grow upward. As the tree matures, it assumes an upright-rounded habit. When young, paperbark maple has an upright-oval to oval-rounded growth habit. It reaches maturity after 12 to 15 years. It has a slow growth rate, gaining 6 to 12 inches a year. The tree is widespread across much of Europe and the United States, where it is a popular ornamental plant. The specimens that do exist tend to grow in isolation, and be large in stature. Paperbark maple can be found in China, but has become increasingly rare. It is renown for its copper-colored, exfoliating bark. Paperbark maple is a popular ornamental tree in Europe and the United States. Though once common in its native territory, deforestation and a lack of conservation have caused it to become endangered. It is indigenous to the forests of Central China. Paperbark maple ( Acer griseum), also called Chinese paperbark maple or paper-barked maple, is a flowering tree in the family Sapindaceae.
