Datura wrightii, commonly known as sacred datura, is a poisonous perennial plant species and ornamental flower of the family Solanaceae native to the Southwestern United States and northwestern Mexico. It is a vigorous herbaceous perennial that grows 30 cm to 1.5 m tall and wide. The leaves are broad and rounded at the base, tapering to a point, often with wavy margins. The flowers are the most striking feature, being sweetly fragrant white trumpets up to 20 cm (7.9 in) long, sometimes tinted purple, especially at the margin. Five narrow points are spaced symmetrically around the rim.
All parts of Datura plants contain dangerous levels of anticholinergic tropane alkaloids and may be fatal if ingested by humans, livestock, or pets. In some places, it is prohibited to buy, sell or cultivate Datura plants. It is sometimes used as a hallucinogen due to its psychoactive alkaloids.
