Poison hemlock growing locally
June 9, 2022
Poison hemlock has been sighted growing locally. A native of Europe, this plant is in the parsley family. It grows to 6 to 10 feet tall. Stems are stout and purple-spotted. Plant typically is extensively branched with shiny leaves, finely divided like parsley or carrot. White flowers are borne in many white shaped umbrella-shaped clusters. This plant occurs in pastures and along roadsides. Poison hemlock thrives in poorly drained soils and frequents ditch banks.
All parts of the plant are poisonous to humans and animals. If you find this plant, carefully remove wearing gloves. Do not compost or burn. Burning will release toxins in the air. Herbicides work well on this plant. If you see this plant or suspect it, call Wahkiakum County Noxious Weed Control at 360-795-3852. Happy gardening! Submitted by Weed Supervisor Andy Lea.
