Dangerous 10-Foot Megaweed Invades New York

Giant hogweed might sound like something out of Harry Potter, but it's straight out of New York. This noxious weed has spread across the state, threatening humans with sap that causes severe burns, blistering, permanent scarring and even blindness.

The outbreak has grown so bad that the N.Y. Department of Environmental Conservation (DEC) has issued a giant hogweed warning and set up a hotline.

Giant hogweed is native to the Caucasus region of Eurasia, and was brought to the United States in the early 1900s. The gargantuan plant blooms bunches of tiny white flowers the size of umbrellas, which made it a showpiece in ornamental gardens, including one in Rochester, N.Y. In the century since it was planted there, it has spread across the state, with 1,004 confirmed sightings so far this blooming season.
