An evergreen perennial herb naturalised in rough grassland and on woodland edges, roadsides and waste ground. It spreads by short, thick rhizomes, but is apparently self-incompatible and rarely sets seed. Generally lowland, but reaching 430 m W. of Nenthead (Cumberland).
This species has been cultivated in British gardens since 1658. Its vigour means it is often thrown out with garden rubbish. It was recorded in the wild in 1853 (Angus), and is much more frequent now than shown in the 1962 Atlas.
Native of S.E. & E.C. Europe and W. Asia, east to Iran and the Caucasus; the western L. punctata and the eastern L. verticillaris do not appear to be specifically distinct.
