Ecology

A perennial creeping herb of woodland, hedgerows, banks, and other moist, usually shaded, habitats; also in rough montane grassland, grikes in limestone pavement, Vaccinium communities, bryophyte-rich block screes, and rock ledges. It grows on both calcareous and non-calcareous soils, though only those which are moisture-retentive. It is one of the few species able to survive the deep shade of conifer plantations. 0-1160 m (Ben Lawers, Mid Perth).
