A pernicious weed. The leaves in the photo on this site do not seem to match those found if you Google the name. Those leaves are much more linear. Perhaps there is just much variation in this plant.

Found all over North America, even up to Yukon and south Canada. Is suspectible to powdery mildrew but it doesn't kill them. Grow sun/shade, even dry shade in rich or poor soil. Have sticky seed pods that will cling to skin or clothes but doesn't have burrs thought they still will give a small hurt. Pulls easily since have shallow roots and have trouble competiting against other aggressive plants.
