Jimson Weed. Datura stramonium, known by the common names thornapple, Jimson weed, or devil's trumpet, is a poisonous flowering plant in the Daturae tribe of the nightshade family Solanaceae. Geoegia O'Keeffe portrayed the Jimson weed's large, trumpet-shaped blossoms with a focus on their soft, curving lines and delicate textures, often giving the flowers an almost otherworldly presence. Her approach stripped the plant of its toxic associations, transforming it into a symbol of the sublime. Jimson weed's likely origin was in Central America, and it has been introduced in many world regions. It is an aggressive invasive weed in temperate climates and tropical climates across the world. D. stramonium has frequently been employed in traditional medicine to treat a variety of ailments. It has also been used as a hallucinogen, taken entheogenically to cause intense, sacred or occult visions. It is unlikely ever to become a major drug of abuse owing to effects upon both mind and body frequently perceived as being highly unpleasant, giving rise to a state of profound and long-lasting disorientation or delirium with a potentially fatal outcome. It contains tropane alkaloids which are responsible for the psychoactive effects, and may be severely toxic. Mature and immature seed capsules Datura stramonium is an erect, annual, freely branching herb that forms a bush up to 60 to 150 cm tall. The root is long, thick, fibrous, and white. The stem is stout, erect, leafy, smooth, and pale yellow-green to reddish purple in color. The stem forks off repeatedly into branches and each fork forms a leaf and a single, erect flower. The leaves are about 8 to 20 cm long, smooth, toothed, soft, and irregularly undulated. The upper surface of the leaves is a darker green, and the bottom is a light green. The leaves have a bitter and nauseating taste, which is imparted to extracts of the herb, and remains even after the leaves have been dried. Datura stramonium generally flowers throughout the summer. The egg-shaped seed capsule is 3 to 8 cm in diameter and either covered with spines or bald. At maturity, it splits into four chambers, each with dozens of small, black seeds. Fruits and seeds-MHNT The genus name is derived from the plant's Hindi name, ultimately from Sanskrit, 'white thorn-apple'. The origin of Neo-Latin stramonium is unknown; the name Stramonia was used in the 17th century for various Datura species.
