|Description||Long grown in North America, the hedge maple is a widely adaptable, trouble-free small tree for smaller urban spaces. It has a lovely texture from its rounded, lobed leaves and grows well in tough urban sites. Bright yellow fall colour and prunability place this tree on the list of trees to choose.|
|Usage||Tall hedge, parking lot island, buffer strip, patio, shade tree, specimen, sidewalk; settings away from natural areas|
|Form/texture||Rounded with low branching creating short trunk|
Slender branches, often with corky fissures, give a medium to fine texture
|Growth rate||Slow; moderate lifespan|
|Leaf||Opposite, simple, lobed dark green with yellow fall colour|
|Exposure/culture||Full sun to part shade|
All soil textures, pH adaptable
Moderate salt tolerance
Extremely drought tolerant
Tolerates tight pruning
Pest resistant, though tar spot and verticillium wilt do occur
|Comments||Adaptable to fairly tough sites, this species has some potential for more use in urban areas. |
"Probably the best maple for dry, alkaline soils" (Dirr).
The dark-green leaves have rounded lobes and are smaller than the other, more commonly grown maple species in Ontario. While ultimately not a tall tree, hedge maple does eventually develop a fairly wide crown, which at low heights will limit it as a street tree in some situations.
Maple tar spot infection is not currently as severe as seen on Norway maple (Acer platanoides).
The plentiful seeds germinate easily; caution near natural areas as it is now listed as invasive in Ohio (www.invasiveplantatlas.org/trees.html).
