One of North America’s most poisonous plants, and it’s growing right on the corner by our house. You don’t even have to ingest it; it’s poisonous to taste. Many recorded deaths of people, and apparently it kills a lot of grazing livestock. Can grow to 8 feet tall. Parsley family. Native.
Water Hemlock, Cowbane, Poison Parsnip (Cicuta maculata)
