Name This Plant

Buddies and I were walking in Fort Point State Park in Stockton Springs July 8th when we happened upon this plant which reminded us of Queen Anne's Lace on steroids. We tried using the Audubon New England Nature Guide App to identify the plant to no avail. We then tried the simple key on https://gobotany.newenglandwild.org/ and no items matched our description. Then we googled the phrase "giant Queen Anne's Lace." Aha! We made an immediate match - our plant is giant hogweed. Heracleum mantegazzianum, also known as  cartwheel-flower, giant cow parsnip, hogsbane or giant cow parsley is a plant in the family Apiaceae.  It can grow up to 14 feet high and have flowers that measure a foot across. The plant can cause painful irritation, permanent scarring and, in rare cases, blindness. It is phototoxic which means if you get the sap on your skin  and then expose the skin to light, you may have a  response resembling a third degree burn. Giant hogweed is on the federal invasive list. Next step is to call  the cooperative extension so the plant can be treated by professionals.
