Poison Hemlock (Conium maculatum) on May 12, 2024

Submitter does not have a specimen

Description of specimen

It looks like poison hemlock or giant hog weed type species. Needs to be sprayed and dealt with. seems to be worse every year.



We went by that patch and it is poison hemlock. This species is quite common throughout the state and as such it isn't a high priority species for Tualatin SWCD. County road rights of way get sprayed by the county, but they have a great many lane miles to manage and it isn't assured that that specific location will get treated.
