Hedge Maple

Hedge maple is the maple most people walk past without recognizing as a maple at all. The leaves are smaller than what you expect, five rounded lobes, none of them pointed, and the tree itself grows dense and rounded, often as wide as it is tall, with a canopy thick enough to function as a visual screen even before it reaches full size. Native to Europe, North Africa, and western Asia, it has been used as a hedgerow plant for centuries, and that lineage shows in its response to pruning: it takes shearing, repeated cutting, and crown reduction without skipping a beat. In Western Washington, it shows up as a street tree, parking lot shade tree, and occasionally as a clipped formal hedge.

The reason hedge maple keeps appearing in planting plans here is that it tolerates almost everything the region throws at urban trees. Full sun to full shade. Clay soils. Compaction. Drought once established. Salt spray. Air pollution along arterials. It grows fast for a maple and turns a clean gold in fall. The trade-off is that it lacks the dramatic form or fall color intensity of Japanese or red maples, and its shallow, fibrous root system can compete with turf and underplantings. Hedge maple carries the full genus-level disease and pest load, Verticillium wilt, anthracnose, powdery mildew, tar spots, and nineteen diseases plus fifteen pests are tracked on its profile. None of those typically threaten a well-sited tree, but if Verticillium is in your soil, choose a different genus entirely.
