If you find giant hogweed growing in your garden, don't try to remove it without wearing protective clothing and safety glasses. Otherwise, you could end up suffering for a long time, says Sasha Shaw, an educator with the King County Noxious Weed Control Program.
Shaw has seen pictures of people hurt by giant hogweed. She says it's the plant's sap that "makes your skin hypersensitive to sunlight and then the sunlight causes burns and blisters. It can cause reddish to purplish scarring for up to several years.”
