Giant Hogweed (Heracleum Mantegazzianum)


About Giant Hogweed

Giant Hogweed is a perennial that can grow up to 6 m (19ft) in height and not only does it crowd out native plants it poses a serious danger to humans. The plants stem hairs and leaves contain a clear, highly toxic sap. When in contact with the skin, it can cause burns, blisters and scarring, and if it gets in your eyes, it can cause permanent blindness. Giant Hogweed has numerous small white flower clusters in an umbrella-shaped head, with rigid, hollow green stems covered in dark red or purple spots. With dark green, coarsely toothed leaves it is a highly competitive plant due to early-season growth, and the seeds remain viable in the soil for up to 15 years.
