An annual weed of cultivated and waste land, especially where the soil is nutrient-rich. Lowland.
S. nigrum may be native in S.E. England, but it is certainly introduced and usually casual in N. England, Wales, Scotland and Ireland. It was recorded in the wild by 1597. It appears to have declined at the edge of its native distribution, but these populations may have been only casual. Some alien records may refer to subsp. schultesii from S. Europe.
Eurasian Southern-temperate element; widely naturalised outside its native range.
