Threat:
Giant hogweed is a tall (up to 15-20 feet in height), herbaceous, biennial plant that invades disturbed areas across both the Northeast and Pacific Northwestern United States. Giant hogweed is designated as a federal noxious weed because the sap it produces can cause skin sensitivity to UV radiation, leading to blistering and severe burns. Giant hogweed can invade a variety of habitats but prefers moist disturbed soils such as riverbanks, ditches, and railroad right-of-ways. Giant hogweed is native to Europe and Asia. It was first introduced into the United States in 1917 for ornamental purposes.
Distribution:
In 2004, giant hogweed was found near Warsaw, Indiana (Kosciusko County). In 2006, giant hogweed was found near Lakeville (St. Joseph County). Eradication of both giant hogweed sites is ongoing.
