This is a non-native invasive weed called HOG WEED and apparently, is spreading all over North America. It is dangerous to touch the sap of this plant as it causes burns and blindness.
A few years ago, while I was in Atlanta, Georgia, I discovered another invasive non-native plant known as Kudzu. This plant is a climbing, coiling plant which literally smothers trees and any plant in its way.
I have visions of a hitch-hiking plant disguised with glasses and a moustache at the side of the 401 with a sign saying "Anywhere"?
