Datura innoxia is a species in the family Solanaceae. It is more rarely called sacred datura, a common name which is applied more often to the closely related Datura wrightii. It is native to the Southwestern United States, Central and South America.
Datura innoxia is a tuberous-rooted, subshrub that typically reaches a height of 0.6 to 1.5 metres. Its stems and leaves are covered with short and soft grayish hairs, giving the whole plant a grayish appearance. It has elliptic smooth-edged leaves with pinnate venation. All parts of the plant emit a foul odor similar to rancid peanut butter when crushed or bruised, although most people find the fragrance of the flowers to be quite pleasant when they bloom at night. The flowers are white, trumpet-shaped, 12–19 cm (4.5–7.5 in) long. They first grow upright, and later incline downward. It flowers from early summer until late fall. The fruit is an egg-shaped spiny capsule, about 5 cm in diameter.
