A monster plant with flowers the size of umbrellas and sap that causes blisters and blindness is spreading across New York.

It's the giant hogweed, an invasive species, and the Department of Environmental Conservation (DEC) is asking for help locating outbreaks so they can send crews to nip it in the bud.

It appears to be concentrated most heavily out in western New York, but it's popping up in parts of Central New York. Locally, we're seeing it in Onondaga, Madison, Tompkins, Oneida, Lewis, Jefferson, Cayuga and Oswego counties. They're typically seen in rural areas and even some state forests.

Giant hogweeds can grow to 15 feet or more, and they pose a serious health threat. Its sap combined with moisture and sunlight can cause severe skin and eye irritation, painful blistering, permanent scaring and even blindness.

DEC officials recommend you do not touch it. If you think you've been burned by one, contact your doctor. View some graphic photos of the burns hogweeds can cause and read some safety tips.

This is DEC's fourth year of controlling giant hogweed. Six crews totaling 14 people will visit most of the 944 known giant hogweed sites. Sites with less than 400 plants will be controlled by hand cutting their roots; sites with more than 400 plants will be controlled with herbicide.
