Moonflower or Datura? Identifying Your 'Moon by Night' Plant and Its Risks

Identification

"Moon by night flower" typically refers to Datura (jimsonweed, thornapple, angel's trumpet)—large, white, trumpet-shaped flowers opening at night and on cloudy days.

Key Facts

• Each bloom lasts one night; plant blooms continuously until frost.
• Fast-growing in heat; Tennessee plants bloom by late June.
• All parts are highly toxic—fatal if ingested.
• Historically used for hallucinogenic teas (extreme danger).

Safety

• Do not plant where children or pets access.
• Wear gloves when handling.
• Check local regulations—classified as noxious weed in many states.

Note

True moonflower (Ipomoea alba) is a morning glory relative with similar night-blooming habit but less toxicity. Confirm ID before growing.
