The Datura Wrightii is known by many names, such as Sacred Datura and Sacred thorn-apple. This deep green desert plant has beautiful 6-7 inch white trumpet-like flowers that open in the late afternoon and evening and close again in the morning.
Every part of this plant is poisonous to humans and livestock, if ingested, especially the seeds. The leaves can even irritate the skin and cause dermatitis in people with sensitive skin. It is sometimes called Sacred thorn-apple because the fruit is a light green capsule covered with thorny spines.
