Datura wrightii or Sacred Datura is the name of a poisonous perennial plant and ornamental flower of southwestern North America. It is sometimes used as a hallucinogen. Datura wrightii is classified as a deliriant and an anticholinergic.
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 (8 inches) long, often tinted purple, especially at the margin. In clear weather, flowers open at nearly full dark and wither a few hours after sunrise the following morning; in cloudy weather, they may open earlier and last longer.
Datura wrightii is found in northern Mexico and the adjoining U. S. states, as far north as southern Utah, in open land with well-drained soils. It is also commonly planted as an ornamental, especially in xeriscapes.
The name commemorates the botanist Charles Wright.
