Yellow watercrown grass (Setaria flavida)

Yellow watercrown grass (Setaria flavida) is a plant species in the Poaceae, a perennial grass, ribbon-shaped leaves, rough with linear folds, green in color, white hair and grows in slightly shady places.

S. flavida has a stem that grows from an intricate, hairy rhizome. Leaves sparse to completely hairy, blades linear, oval or lance-shaped. Pointed tip, a vein in the middle, pleated texture and coarse or hairless.



The grains are in panicles, yellowish-green in color, open and spreading. Spikelets are several millimeters long and are often accompanied by hairs. The grass is vigorous and spreads by rhizomes and seeds, forming monotypic stands in shaded areas, primary forest, agricultural fields, roadsides and wastelands.
