<em>Datura stramonium</em>, the common thorn apple or jimsonweed, is an annual herbaceous plant in the family Solanaceae, believed to be native to Central America or southern North America but now cosmopolitan, occurring in over 90 countries across temperate and tropical regions worldwide. It is Not Evaluated on the IUCN Red List as a widespread weed. The plant grows in disturbed soils, waste ground, roadsides, agricultural fields, and gardens. It bears large, lobed leaves with an unpleasant odor, distinctive white to pale violet trumpet-shaped flowers, and spiny seed capsules. All parts of <em>Datura stramonium</em> are highly toxic, containing tropane alkaloids including scopolamine, hyoscyamine, and atropine, which can cause severe poisoning in humans and livestock. Despite its toxicity, it has a long history of medicinal and ritual use across many cultures. The species is considered an invasive weed in many agricultural contexts. Biological traits such as seed output per plant, precise lifespan, and biomass data remain poorly documented in standardized global assessments.
