Poison hemlock: This aromatic plant is found mostly in Stanwood and the lower part of Snohomish. Its most distinguishing feature is a smooth stem with purple splotches. All of the plant is toxic for livestock and humans. Wear gloves to dig it out. Bag the seeds and flowers and throw them into the trash. (Snohomish County Noxious Weed Control Board)
