Invasive Plant Advisory
Giant hogweed (Heracleum mantegazzianum) poses a serious threat to human health and the environment. The clear sap found in its stem and hairs can result in severe burns and blistering and if the sap enters the eyes, it can cause temporary or permanent blindness.
If you find giant hogweed on your property, it needs to be removed as per the City’s Noxious Weed Bylaw Number 4181, 2010. It is best to let a professional remove this plant.
