Scary plant! #341193

Asked July 09, 2016, 5:21 PM EDT

This plant has begun spreading next to my house.  It is near by bird feeder which contains various sunflower, millet, safflower, and nyjer seeds.  The leaves leave a terrible chemical smell on your hands if you touch them, and when pulling the plant out the chemical smell is nauseous.  The tallest plant is 5 feet.
