Acer campestre

Field Maple / Common Maple / Hedge Maple

Botanical Name: Acer campestre
Family: Sapindaceae
Origin: Europe, western Asia and northern Africa
Plant Type: Deciduous shade tree

Overview

Acer campestre — the Field Maple — is a tough, broad-domed deciduous tree beloved across cool and temperate Australia for its dense round canopy, distinctive corky bark and spectacular golden-yellow autumn colour. Remarkably adaptable, it tolerates dry alkaline soils, clay, urban pollution and hard frosts, making it one of the most reliable large shade and avenue trees for Adelaide's temperate and Hills climates. At full maturity it is a substantial specimen, so it rewards spacious plantings where its layered seasonal interest — spring green flush, dense summer shade and glowing autumn finale — can be fully appreciated.

Key Features

• Mature Size: 15 m H × 10 m W
• Growth Rate: Moderate; 40–60 cm per year once established; upright-to-broadly-domed with a self-branching, dense canopy that fills steadily over time
• Foliage: Small, five-lobed leaves with rounded tips; emerges fresh apple-green in spring, darkens to a rich deep green through summer, then turns a brilliant clear golden-yellow in autumn before dropping to reveal an attractive corky-barked branch structure through winter
• Flowers: Small, yellow-green clusters (corymbs) appearing September–October (southern-hemisphere spring); non-fragrant and inconspicuous individually, but collectively attractive to pollinators; followed by paired winged samaras (helicopter seeds) that hang in clusters well into winter
• Seasonal Interest: Four seasons of interest — spring leaf emergence, dense summer canopy for shade, fiery golden autumn foliage, and architectural bare-branch winter silhouette with corky bark texture
• Wildlife Value: Spring flowers attract bees and other beneficial insects; samaras provide seed food for birds; dense canopy offers nesting habitat
• Tolerance: Frost hardy (survives heavy and frequent frost); drought-tolerant once established; tolerates dry alkaline and compacted soils; tolerates clay with improved drainage; wind-tolerant; urban pollution-tolerant; heat-tolerant in temperate conditions with adequate summer water
• Planting Density: Feature / shade tree: plant 6–8 m apart to allow full canopy development; Avenue or streetscape: 4–5 m apart for a formal, close-canopied avenue effect; Informal windbreak or screening row: 1.5–2.5 m apart, maintained with annual pruning
• Pet Friendly: Acer campestre is not listed as toxic to dogs or cats by major veterinary authorities; the winged samaras and bark are considered low-risk. However, as with all trees, prevent pets from ingesting large quantities of leaves or seeds; keep mulch clear of the trunk to discourage digging around the root zone

Where It Works Best

• Sunlight: Full sun preferred for densest canopy and best autumn colour; tolerates part shade (up to half-day shade) but may develop a slightly more open form
• Soil: Best in well-drained loam or sandy loam; adaptable to clay soils when drainage is improved with gypsum and organic compost; tolerates dry alkaline conditions and compacted urban soils better than most maples; enrich planting hole with quality compost and aged manure at establishment
• Water Needs: Establishment (first 12–24 months): water deeply twice per week throughout the first two summers, reducing frequency in cooler months to once per week; maintain a 75–100 mm organic mulch layer clear of the trunk. Established: summer — deep water once per week during extended dry spells or heatwaves; winter — rainfall generally sufficient, supplementary watering minimal to none
• Maintenance: Low once established; prune in late winter only to remove dead or crossing branches and to gradually lift the canopy; apply a balanced slow-release fertiliser in early spring; mulch annually; inspect for scale or caterpillars in warm conditions
• Lifespan: Long-lived; 80–150+ years in suitable conditions
• Climate Zones: Best suited to Adelaide Hills, southern Adelaide plains and temperate inland (Mt Barker, Strathalbyn, Clare Valley); performs well in cool-temperate to temperate Mediterranean climates; grows in warmer plains with deep soil and summer irrigation; not suited to humid subtropical or tropical conditions
• Soil pH: Adaptable from mildly acidic to neutral to mildly alkaline (pH 5.5–7.8); tolerates lime-rich soils

Landscape & Design Ideas

• Grand Avenue Planting: Plant 4–5 m apart along a driveway or property boundary for a classic European-style avenue that delivers tunnels of summer shade and a canopy of gold each autumn
• Feature Shade Tree: Position as a centrepiece lawn specimen in medium to large gardens, allowing at least 6 m clearance from structures; the deciduous habit admits warming winter sun while providing dense summer cooling — ideal for Adelaide's Mediterranean climate
• Informal Windbreak / Screening Row: Mass-planted at 1.5–2.5 m spacing and kept pruned, Field Maple forms a dense deciduous hedge or windbreak suited to rural properties, acreage lots or large Adelaide Hills gardens requiring seasonal wind protection

Why You Will Love It

If you want a tree that genuinely earns its space all year long, Acer campestre delivers in spades — spring freshness, full summer shade, a blazing golden autumn and a sculptural winter silhouette, all wrapped in a package that laughs at frost, alkaline soils, urban pollution and dry spells once it has its roots down. It is the workhorse of European-style South Australian gardens: tough enough for the Adelaide Hills, adaptable enough for the southern plains, and beautiful enough to anchor the most considered landscape design. Plant one now, and in twenty years it will be the tree your whole garden is built around.
