What is the Giant Hogweed?

The Giant Hogweed (Heracleum mantegazzianum) is a highly invasive plant species that is native to the Caucasus region of Eurasia. It was introduced to North America and Europe as an ornamental plant in the 19th century, but has since become a serious problem in many areas.

Giant Hogweed can grow up to 5 meters (16 feet) tall and has large, umbrella-shaped flowers that can reach up to 1 meter (3 feet) in diameter. Its leaves are also quite large, measuring up to 1.5 meters (5 feet) in width, and are deeply lobed and serrated. The plant’s sap contains toxic chemicals that can cause severe skin irritation and burns when exposed to sunlight, and can even cause blindness if it gets into the eyes.

Giant Hogweed is considered a noxious weed in many countries and is actively managed and controlled to prevent its spread. It is important to avoid contact with the plant and to take precautions when handling it, such as wearing protective clothing and washing skin that comes into contact with the sap thoroughly with soap and water.
