That Freaky Plant That Makes You Blind? Yeah, It's Also In PA, NJ

As you’ve probably heard by now, giant hogweed, an invasive species of plant that can leave you with third-degree burns or blind, was recently discovered in Virginia. But what you might not know is that researchers previously found the plant in Pennsylvania and New Jersey, too.

The plant, listed federally as a noxious weed, is characterized by its white, umbrella-shaped-flower clusters and closely resembles cow parsnip. The plant can grow much taller though — up to 14 feet.

Researchers at the Center for Invasive Species and Ecosystem Health at the University of Georgia run an online mapping system to record when and where invasive species are found. The real-time tracker, dubbed the Early Detection and Distribution Mapping System, provides state, county, point and GIS data for invasive species, including giant hogweed.

The good news for Philadelphia-area residents is that the plant was not found in the eastern part of the state. According to the tracker, the plant has presently been found in just two Pennsylvania counties: Erie and McKean.

But it was also found in three New Jersey counties that are near Pennsylvania, including Warren, Somerset and Morris.

Other states that have seen the plant include: New York; Connecticut; Massachusetts and more.

New York health officials minced no words on its website when it came to the giant hogweed: “Do Not Touch This Plant!”

“Its sap, in combination with moisture and sunlight, can cause severe skin and eye irritation, painful blistering, permanent scarring and blindness,” the New York health department said.

Most recently, about 30 of the plants were found by Virginia Tech researchers in Clarke County, Virginia. While the scientists asked residents to watch for the plant, they emphasized that in that particular case, the weeds were likely planted intentionally decades ago and hadn’t spread.

“It’s a dangerous plant but I’m not overly concerned about it. This seems to be an isolated incident,” said researcher Michael Flessner, an assistant professor and extension weed science specialist. The researchers strongly advised against mowing or weed-whacking the plant without wearing proper covering and safety gear.
