i have experience of giant hogweed burns, very, very nasty (like after snapping a flowering spike, the skin on the palm of my right hand pealed off over the next week, as well as splash marks where the sap had hit my arms, legs and side of my face!) and i still have the scars nearly 10 years later - this stuff is nasty to the extreme!!
easy way to tell the difference between native and giant hogweed, if its flowering and its bigger than shoulder height - its giant hogweed, its illegal to grow it anywhere and its the land owners responsibility to remove it once it is discovered
