Land Plants - invasive

Poison Hemlock (Conium maculatum) on Apr 21, 2016

Submitter does not have a specimen

Description of specimen

Parsley/carrot family appearance; fern-like leaves with purple splotches on the stems.

Commentary

Thanks for the report, Lisa. There really aren't any requirements for removal of poison hemlock, although, sure, it's certainly recommended. Vacant lots are tricky when it comes to contacting owners; we typically send letters (for other species) to the owner listed on portlandmaps.com.

King County, WA: Poison Hemlock

Location

Poison hemlock (among other invasive species) in a vacant lot addressed 2625 SW Corbett. It's adjacent to a sidewalk that is frequently used by students to and from school as they pick wildflowers; concerned about safety due to the poisonous nature of the plants should they be tempted to pick the flowers once in bloom.
