Summer annual broadleaf
A summer annual with hairy leaves and stems, reaching 2 feet in height. Hairy galinsoga is primarily a weed of vegetable crops, but it may occur in any cultivated situation. Seedlings have cotyledons that are club shaped with a slightly indented tip. Leaves are opposite, oval to triangular and coarsely toothed. They occur on petioles and are densely covered with hairs on the upper surface. Lower leaf surfaces have hairs that primarily occur on the veins. Many flowers are produced on each plant. They consist of four to five white (less often pink), three-toothed ray flowers (outer flowers) and many yellow disk flowers (inner flowers).
