Hairy galinsoga

Galinsoga quadriradiata (Galinsoga ciliata)

Galinsoga quadriradiata is a species of flowering plant in the daisy family which is known by several common names, including shaggy soldier, Peruvian daisy, hairy galinsoga, and fringed quickweed.
Galinsoga quadriradiata is an annual herb which varies in appearance. The main stem reaches anywhere from 10 to 60 centimeters (4-24 inches) in height and may branch or not. The petioled leaves are ovate and serrated are opposite branching, and covered coarse, hispid hairs. G. quadriradiata has a fibrous root system.
The small flower heads are up to a centimeter wide (0.4 inches) but typically 2-3mm in diameter and have rounded center filled with many disc florets usually in a shade of bright yellow. There are five white ray florets widely spaced around the center, each an oval shape typically with three crenate teeth at the tip. Both the disk and ray florets are fertile producing a achene with a large pappus.
As an agricultural weed it can reduce crop yields by up to 50%.
