Atropa belladonna is native to south central Europe, northern Africa, and western Asia. However, it has been introduced and naturalized in other areas, and is occasionally found as a weedy species in certain areas of Canada and the United States (Scott 1991). The distribution limits are between 50° and 55° N latitude and 300 to 600 feet above sea level in altitude. However, it can occasionally be found at sea level in areas where there is well-drained, calcareous soil and adequate amounts of shade (Rita & Animesh 2011).
