Its relatively fine texture sets it apart from other landscape plants with less refined foliage. The lobed leaves turn outstanding shades of orange, scarlet and burgundy in the fall.Īmur Maple is a deciduous tree with a strong central leader and a more or less rounded form. It features abundant showy red samaras in late summer. With any treatment it will be necessary to monitor for and treat regrowth and new seedlings in subsequent years.A choice small tree, among the hardiest of all maples incredible fall colors ranging from orange to scarlet and burgundy red, neat habit and colorful seeds in late summer, one of the best accent trees for small home landscapesĪmur Maple is primarily grown for its highly ornamental fruit. Herbicide should be selected carefully based on site conditions, and label directions read and followed carefully. Prescribed fire can prevent Amur maple establishment in fire adapted communities such as prairies and savannahs, but must be repeated annually if possible.Ĭhemical control and combined approaches: Cut stump and basal bark herbicide treatment can be applied most of the year, outside of early spring when sap is flowing upward. Mowing can suppress seedling growth near adult plants on managed landscapes, but must be repeated frequently. Roots must be removed to prevent resprouting. Physical control: Small plants are easily hand-pulled from moist soil larger saplings can be dug or pulled using equipment, such as a weed wrench. If control is undertaken on mature plants when seeds are present, it is best not to remove any plant material from the site to avoid spreading seed. Whenever possible, plants should be controlled as seedlings and while populations are small. Natural areas close to places where this species has been planted should be monitored closely for seedlings. Timing and spread concerns: Amur maple is still relatively uncommon around the Great Lakes region, so a good defense is the best offence. For local assistance managing woody invasive species, please get in touch with a cooperative invasive species management group or a university extension program.
#AMUR MAPLE HOW TO#
For more detailed information on how to use these techniques, please visit our Management and Control page. The following is a brief overview of management techniques shown to be effective on Amur maple, though there is relatively little information available about management of this species. Yellow = native to the United States but not to the Basin Green = native to part of the Great Lakes Basin Girard’s paperbark maple ( Acer griseum x nikoense )Ī Listed cultivars have the indicated trait, but the straight species (or hybrid) may not. Alternatives for Amur MapleĬanada serviceberry ( Amelanchier canadensis )Īpple serviceberry ( Amelanchier x grandiflora ), ‘Autumn Brilliance,’ ‘Princess Diana,’ ‘Cumulus’Īmerican hornbeam ( Carpinus caroliniana ) Please see our Landscape Alternatives pages for more information about how the WIGL Collaborative selected alternatives. The leaf shape is somewhat similar to the native ninebark ( Physocarpus spp.), but ninebark has alternate leaves, while those of Amur maple are opposite.
Amur maple is much smaller at maturity than any native maple species, with smaller samaras. It is most similar to Tatarian maple ( Acer tataricum ), another small exotic maple with unlobed leaves that frequently has a single main stem. Look-alikes: Amur maple can be distinguished from other maples by its leaf shape, particularly the long middle lobe. The small size of the samaras (each side is ¾ – 1” long) along with the coloration can help distinguish from other maples. Samaras are often pink or reddish in the summer, ripening to brown. They are the papery, winged two-chambered samaras characteristic of maples. Fruits appear over the summer and mature in early-to-mid fall. Flowers are fragrant, unlike other maples. Flowers emerging in mid spring are yellowish white, small, and born in small, branched clusters.
Leaf edges are toothed, and leaves are dark green in summer, sometimes changing to yellow or red in fall (fall foliage color varies by cultivar and planting situation). Leaves have three lobes, and the middle lobe is much longer than the side lobes. The leaves are opposite each other, and are generally 1 ½ to 3” in length. It is common for this species to grow multiple stems and for the crowns to be as wide as the plants are tall. Identification: Amur maple is a large deciduous shrub to small tree, generally 15-18’ tall at maturity.
