Giant Hogweed [Heracleum mantegazzianum]

Giant hogweed, a dangerous invasive species, is currently growing and spreading along the banks of the Grand River and elsewhere in our community. The hogweed’s danger lies in its clear and watery sap. If the sap from a broken stem or crushed leaf, root, flower or seed comes into contact with skin, it can cause severe burns, blistering and painful sores when the skin is exposed to sunlight. If the sap comes into contact with the eyes, it can lead to temporary or permanent blindness.
