The Devil’s Trumpet (Datura inoxia) is an annual shrubby plant that typically reaches a height of 0.6 to 1.5 meters. Its stems and leaves are covered with short and soft grayish hairs, giving the whole plant a grayish appearance. It has elliptic entire-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 long. They first grow upright, and later incline downward. It flowers from early summer until late fall.
All parts of Datura plants contain dangerous levels of poison and may be fatal if ingested by humans and other animals, including livestock and pets. In some places it is prohibited to buy, sell or cultivate Datura plants.
The fruit is an egg-shaped spiny capsule, about 5 cm in diameter. It splits open when ripe, dispersing the seeds. Another means of dispersal is by the fruit spines getting caught in the fur of animals, which then carry the fruit far from the mother plant. The seeds have hibernation capabilities, and can last for years in the soil. The seeds, as well as the entirety of this plant, are also hallucinogenic, and have a high probability of overdose.
