Datura stramonium

Datura stramonium, known by the common names augushka, jimson weed, ditch weed, stink weed, loco weed, Korean morning glory, Jamestown weed, thorn apple, angel's trumpet, devil's trumpet, beelzebub's twinkie, devil's snare, devil's seed, mad hatter, crazy tea, and malpitte, is a common weed in the Nightshade family.

All parts of Datura plants contain dangerous levels of poison and may be fatal if ingested by humans or animals, including livestock and pets.

Datura stramonium is native to either India or Central America. It was used as a mystical sacrament in both possible places of origin. Aboriginal Americans in the United States have used this plant in sacred ceremonies.
