Jimsonweed (Datura stramonium): The Toxic, Weedy Devil's Trumpet

Jimsonweed, also called devil's trumpet or common thorn-apple, is a large, coarse annual weed with spiny seed pods and large, white, trumpet-shaped flowers that open at night. Native to North America but now cosmopolitan, Datura stramonium is notorious for its extreme toxicity—all parts contain dangerous tropane alkaloids.

Identification and Caution

It grows 3-5 feet tall with coarse, toothed leaves and spiny, egg-shaped capsules that split open to release numerous seeds. The flowers are fragrant at night. It thrives in disturbed soils, roadsides, and fields. DO NOT INGEST. Handle with gloves. Remove from areas accessible to children and pets.

Historical Context

Historically used in traditional medicine and rituals, but its narrow therapeutic window makes it extremely dangerous. Modern horticulture focuses on ornamental cultivars of other Datura species.
