There’s been much hype lately about the invasive plant species commonly called giant hogweed (Heracleum mantegazzianum). Although from a different family, it has similar toxicity to the wild parsnip (Pastinaca sativa) which is so prevalent in this part of the country.
Should you come across giant hogweed during your hikes/travels, please don’t touch. If you accidentally come in contact with this plant, immediately cleanse the affected area and stay out of the sun for at least 48 hours. Also immediately contact your local DNR or Land Conservation office and alert them to the location. Here’s a good summary.
