Groundsel is a flowering plant in the daisy family Asteraceae, with a shallow taproot. This plant spreads by reseeding itself.
Groundsel grows in hard and salty soil, with good drainage but with low organic matter. The occurrence of groundsel may indicate very low Phosphorus levels.
Groundsel acts as a host for the fungus that causes black root rot in peas, alfalfa, soybeans, carrots, tomatoes, red clover, peanuts, cucurbits, cotton, citrus and chickpeas.
