Officials Warn Of 'Poison' Plant Spotted In Washington

Washington officials are warning residents about the presence of a toxic plant seen around at least one region of the state.

The King County Department of Natural Resources and Parks (KCDNRP) has issued a warning about the presence of conium maculatum, also known as poison hemlock, a toxic plant, in various locations across the county. The plant, which is often mistaken for carrots, Queen Anne's lace, or parsnips, has been spotted in parks, fields, school grounds and along roadsides, according to KingCounty.com.

Poison hemlock is a biennial plant in the carrot family that can cause illness or even death in both people and animals if ingested, per KING 5. The plant is characterized by its bright green, fern-like leaves, and tiny white flowers arranged in umbrella-shaped clusters. The stems of the plant are hollow and often have reddish or purple spots and streaks.

"We find poison hemlock all over this region — in parks, open spaces, along roadsides, we find it unfortunately near playgrounds and schools, we also find it near community gardens and in pastures," said Rahel Stampfer, the policy and communications manager for KCDNRP's Noxious Weed Control Program. "So we're really on the lookout for those impactful places where we want to make sure it doesn't get accidentally eaten."

The department advises residents to remove the plant from their property if they find it, and to dispose of it in the trash rather than composting it. While the plant is not harmful to touch, it is recommended to wear gloves when handling it.

The KCDNRP is working with other agencies to remove the plant from public spaces and is encouraging residents to report sightings of the plant to help control its spread. Reports can be made on the King County government website.
