An annual of waste ground, rubbish tips, cultivated and disturbed ground. Most populations are casual, but the species can become naturalised, or reappear after long periods from dormant seeds. It most frequently arises as a garden escape or from bird-seed, but also from oil-seed and grain. Lowland.
D. stramonium was cultivated in Britain by 1597 and was grown commercially for alkaloids used to treat asthma. It was first recorded in the wild in 1777. Casual populations make changes in its distribution difficult to assess, but it may have declined in recent years.
Native range unknown, possibly America or the Black Sea region; now widespread in temperate and sub-tropical regions.
