If you come in contact with this plant, the reaction can be severe—think poison ivy times 100. With this year’s wet spring, Poison Hemlock is thriving and spreading fast. In the coming weeks, you may see fields blanketed with delicate white flowers… but do NOT be fooled. This plant is extremely toxic.

How to Identify Poison Hemlock:
Grows 6–10 feet tall
Umbrella-shaped clusters of small white flowers
Fern-like leaves resembling parsley
Distinct purple or maroon blotches on smooth green stems
Often found along roadsides, creeks, ditches, and field edges

Why It’s Dangerous:
Every part of Poison Hemlock—leaves, stems, flowers, seeds, and roots—is deadly if ingested. Even skin contact can cause serious reactions for sensitive individuals, especially if the plant oils enter through cuts or if sap is transferred to the eyes or mouth. Inhalation of fumes during mowing or burning can also be harmful.

Symptoms of Poisoning May Include:
Nausea, vomiting, rapid heartbeat
Muscle paralysis
Respiratory failure
Death (even small amounts can be fatal)

Important Safety Tips:
NEVER touch or handle this plant without gloves and long sleeves
NEVER burn it—smoke is toxic
Wash skin thoroughly if contact occurs
If ingested or severe symptoms develop, seek emergency medical help immediately

Report sightings to local extension offices if the infestation is large
Poison Hemlock closely resembles wild carrots or Queen Anne’s Lace, making it especially dangerous to foragers and kids. Know the difference. Teach your children and neighbors. Awareness can save lives.

Stay safe, stay informed, and always double-check before you touch or taste anything growing wild.
