Field sandbur is a warm-season annual grass. It poses a problem since it grows in all locations but favors sandy or well-drained gravelly soils. Young plants, often purplish, usually grow horizontally, spreading across the ground. There are 10 to 30 burs per cluster and 8 to 40 spines per bur, with a rough leaf surface. Blades measure 10 to 25 cm long, with a smooth surface. It generally consists of dense, bushy growth.
