This annual is a frequent colonist of fertile and disturbed soils, and is found in cultivated and waste ground, gardens, hedgerows, on roadside verges, along railways, around rock outcrops and in rough grassland. 0-610 m (Grasshill, Co. Durham).
As in the 1962 Atlas, L. purpureum is present in nearly all lowland areas but the map suggests a decline in Scotland, possibly due to the abandonment of marginal arable land.
As an archaeophyte L. purpureum has a European Temperate distribution; it is widely naturalised outside this range.
