Acer

Britain's only native maple and one of Europe's most genuinely useful small trees — a tough, modest, rounded-crowned species native across Europe, north-west Africa and south-west Asia (POWO). Where its relative the sycamore sprawls and self-seeds aggressively, the field maple stays compact, well-behaved and not invasive, shrugging off dry, chalky, alkaline and clay soils, exposure and urban pollution. Small five-lobed leaves turn a clear butter-yellow (sometimes flushed red) in autumn, the corky-winged twigs give winter character, and the small green flowers feed bees in spring. The honest pitch: not a showy specimen, but a dependable, wildlife-friendly workhorse for small gardens, hedges and street plantings on the difficult soils where flashier maples sulk.

A refined small deciduous tree from the mountains of Japan, Manchuria, and Korea, grown above all for its nearly round, many-lobed leaves and its brilliant red-orange autumn color. It builds slowly to a rounded, spreading 15-30 feet, carrying small reddish-purple flowers in spring before the foliage hardens. A classic specimen and dappled-shade understory tree that resents hot, dry, windy sites; not native to North America.

A deciduous small tree or large shrub from Japan and Korea, grown above all for its delicate palmate leaves — five to seven (rarely nine) pointed, toothed lobes — and its sculptural branching. It reaches 10-25 feet over decades, carries insignificant reddish-purple flowers in April, and finishes the season in shades of yellow, red-purple, and bronze. A classic specimen and dappled-shade understory tree; not native to North America.

The most widely distributed deciduous tree in eastern North America and one of the few that thrives across a 7,000-foot elevation range from Newfoundland to Florida. Earliest spring bloom of any eastern hardwood (January-March in NC) gives early-emerging bees their first nectar source; brilliant red fall color is the species's headline, but the timing varies tree-to-tree — making cultivars with named selections ('October Glory', 'Red Sunset') the reliable design choice for guaranteed display.

The Canadian flag tree and the foundation of the eastern North American maple syrup industry — and one of the most reliably beautiful fall-color trees in the temperate world, with brilliant red, orange, and yellow leaves often on the same canopy. Slower-growing than red maple but longer-lived (200-300 years in optimal sites) with denser shade and superior wood. Intolerant of compacted soil, road salt, and high heat — site away from streets and parking lots.

A large, fast-growing deciduous maple reaching roughly 60-90 feet with a broad, domed crown, big five-lobed leaves, and the maple's signature paired winged samaras. Its honest virtue is toughness: it shrugs off wind, salt spray, and air pollution better than almost any other large tree, which has long made it a classic coastal and exposed-site shelterbelt. Its honest liability is that it self-seeds aggressively — outside its native montane range it has naturalised so freely that it is widely regarded as an invasive weed tree (notably across Britain and in parts of North America), with seedlings appearing everywhere. Native to the mountains of central and southern Europe and the Caucasus (POWO), it is best reserved for exposed, salt-laden, or polluted sites where its resilience earns its keep and where its prolific seeding is acceptable — and never near horse paddocks, because its seeds and seedlings are toxic to horses.

A Pacific Northwest native small maple of understory + woodland-edge habitats producing rounded palmate leaves with brilliant red-orange fall color + a delicate multi-stemmed shrubby-to-small-tree habit. Native to the Cascade + Coast Range forests; thrives in cool moist Pacific Northwest conditions where eastern maples struggle. Among the most graceful native ornamental small trees for shaded gardens.
