Hedera helix subsp. hibernica
An evergreen perennial climber of woodland, scrub, hedgerows, walls, rock outcrops and cliffs, which may also sprawl over the ground. It avoids only the most acidic soils. Altitudinal limit unknown.
This tetraploid subspecies is more frequent in W. Britain and Ireland than subsp. helix. It is much better known than when mapped by McAllister & Rutherford (1990), but remains very under-recorded in some areas, particularly in Ireland. The two subspecies can be difficult to separate. Alien records refer to the cultivar `Hibernica`, which is widely grown and has been found naturalised since at least 1838; separating alien and native populations within the native range can be difficult.
Oceanic Southern-temperate element.
