Description of Hogweed, Giant (Heracleum mantegazzianum):
Giant hogweed looks like something out of Jurrasic Park. It can grow to a whopping height of 15 to 20 feet. Its stems are reddish-purple and have sturdy bristles on them.
The best control method is to kill it at a distance with herbicide before it goes to seed. If removing it by hand, it produces a noxious sap that causes blisters and scars.
