[![leaf is about 3ft tall in a well shaded area, and rough to the touch. It's growing on a river bank in Pa. It looks like a huge parsley type leaf][1]][1]

This plant is new to me I have left Pa. for about 16 years only to find tons of new plants and vines that are all imports and most extremely invasive. I am identifying as many as I can and going to make up a report to submit to the city and possibly volunteer for a cleanup job, though it will take a army at this point. I want to see if these plants are medicinal or edible and where they come from. [1]: https://i.sstatic.net/TygMD.jpg
