Datura inoxia, commonly known as Jimson Weed, Stinkweed, Angel Trumpet, Thornapple or Pricklyburr, belongs to the Solanaceae family.

This low lying, short-lived, self-seeding perennial is often planted as an ornamental, and it grows in pretty much any soil type. It requires little water, but it can become weedy if unchecked.

All parts of this plant are highly poisonous. No part of this plant should ever be injested.

The very hardy Thornapple usually only grows 1-3ft in height, but may spread out several feet. It survives outdoors pretty much anywhere in the United States, except for extreme winter areas.

This species is closely related to, and sometimes confused with or incorporated into Datura stramonium - jimson weed.
