A bulbous perennial herb of damp soils, thoroughly naturalised in woodland and scrub, by watercourses and in grassy places. Lowland.
Although sometimes considered native at two localities in S.W. England, all British populations are almost certainly relics of cultivation or result from surplus garden plants being discarded into suitable habitats; it was being cultivated in Britain by 1596 and was first recorded in the wild in 1866. There has been little change in its distribution since the 1962 Atlas.
A European Temperate species, absent as a native from much of W. Europe.
