I don't usually do plant observations, but am wondering about this because of how popular it was with the wildlife. Saw this plant at varying heights of around 2'-8' along the path. Its seeds were very popular with the rose-breasted grosbeaks, cardinals, chipmunks, and gold finches. I'm hoping it is a local native and not super aggressive.
Jewelweed observed at Snake Road, Larue Pine Hills, Union county Illinois.
