An evergreen perennial of herb-rich, usually deciduous, woodland; also in old hedges, glades, damp grassland, fens and marshes, and shaded gullies and cliffs in upland areas. It is typical of mesic brown earth soils kept relatively open by slope, shade, vernal herbs and disturbance, and avoids places where litter accumulates. 0-820 m (Breadalbanes, Mid Perth).
Mapped as `all records` in the 1962 Atlas, analysis of the database reveals that the widespread decline of L. nemorum in S. England has taken place since 1950. Losses have resulted from woodland destruction and replanting with conifers.
Suboceanic Temperate element.
