The Most Dangerous Plant In Each State

4. Texas – Jimson Weed (Datura stramonium)

Jimson weed grows aggressively across Texas fields and roadsides. Its trumpet-shaped white or purple flowers are striking, but the plant contains dangerous tropane alkaloids like scopolamine and atropine. Ingestion can cause hallucinations, extreme confusion, rapid heartbeat, seizures, coma, and death. Sometimes called “devil’s trumpet,” it has a long history tied to poisonings and misuse for its hallucinogenic effects. All parts of the plant are toxic, including seeds and flowers. Livestock poisoning is also common, making jimson weed a serious agricultural and public health concern.
