Ecology

An evergreen shrub of deciduous woodlands, especially those on acidic soils in which Fagus and Quercus predominate; often a frequent or locally dominant undershrub but rarely dominating the canopy. Its susceptibility to browsing can limit regeneration. It is also found in wood-pasture, scrub and hedgerows, and on ledges of acidic cliffs, and is often planted in amenity areas and parkland. 0?600 m (Eel Crags, Cumberland).
