Submitter does not have a specimen
Description of specimen
The plants were vibrant green and leafy, I used google lens to help identify because my dog seemed keen on it
Thanks for the report. It is indeed poison hemlock and is fatal if eaten. Unfortunately, it is becoming a very successful year for poison hemlock. We are seeing it everywhere.
