Spring brings on toxic plant invasion

Giant hogweed, is a large weed that is toxic to humans and is taking up too much space in our backyards and Ohio countryside. It is invading northern parts of the United States and requires a hazmat team to remove it from your premises.

Giant Hogweed is invading Ohio.

Now the giant hogweed's flowering season is upon us, it's time to bring attention to this obnoxious plant that causes human and environmental suffering. Most hiker's haven't a clue how dangerous this plant is to humans and don't even know it exist.

The weed oozes a poisonous sap that causes severe burns and if it gets in the eyes and mixes with sunlight you can go blind. The Ohio State University says,

"Giant hogweed (Heracleum mantegazzianum​) is on the federal and Ohio noxious weed lists making it unlawful to propagate, sell, or transport....because of its ability to crowd out native plants and because of its potential human health hazard."

One of these weeds can create 20,000 seeds and can spread fast if not controlled. The sap causes blisters and severe burns when exposed to sunlight. It is joked that this weed resembles a giant Queen Anne's Lace plant on steroids but is a royal pain in the derriere.

According to, people choose to put giant hogweed in their gardens, even though the plant is very dangerous it doesn't hinder some gardeners from adding it to their landscape and reports that the poison is located in the weeds stocks.

"Toxic sap lies inside its bamboo-like hollow stalks. If the sap gets on your skin, the exposed area becomes unable to protect itself from the sun's rays, leading to terrible, blistering burns, followed by skin discoloration and darkening that can persist for years." says Discovery's Emily Sohn.
