Datura metel is an ornamental and ritual plant that was domesticated in the region of southern Mexico and Central America prior to European contact; it is derived from a common ancestor shared with D. innoxia. Using old Arabic and Indic references as well as iconographic representations from southern India, R. Geeta and W. Gharaibeh (2007) supported the hypothesis that D. metel was transferred to the Old World at least a millennium ago. Plants escaped from cultivation may persist for only a few years.
