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.
