About plant names...

Although native to Mexico and the southwestern United States, angel’s trumpet is found through much of North America now.

Identification: Angel’s trumpet grows in bushes 24-48" (60-121 cm) high, with grayish-green stems coated with fine hairs. Leaves are alternate, 6" (15 cm) × 4" (10 cm), with smooth margins. The leaves have the unusual property that they are not symmetric at the base— one side is somewhat larger than the other. Flowers are 5-9" (12-22 cm) long, trumpet-shaped, and white, cream-colored, or purplish. The fragrant flowers have several segments, with small points at the edges between them. Fruits are prickly, about 1" (2.5 cm) across.

Edibility: Poisonous Skull & Crossbones Datura contains several poisonous alkaloids that can cause temporary blindness, respiratory depression, seizures, high fevers, and hallucinations. It has been used by some North American native cultures for religious purposes, and more recently, by some as a recreational hallucinogenic. But the effective dosage is dangerously close to the fatal dosage, and panic following temporary blindness causes many injuries as well. See the description of the closely related species D. stramonium for more information.
