Ecology

An evergreen perennial woody climber most characteristic of woodland, scrub and hedgerows, but also common on walls, rock outcrops and cliffs. It may carpet the ground in secondary woodland. It generally favours basic to moderately acidic soils. It is highly palatable to deer and stock, and in grazed upland areas becomes restricted to inaccessible rock outcrops. 0-610 m (Mourne Mountains, Co. Down).
