Summer annual grasses
Green foxtail is an erect-growing grass that reaches a height of 1–2 feet. Auricles are absent, the ligule is a tuft of hair, and sheaths are nearly round and lined with hairs. The blades are hairless with a rough texture and are 4–10 mm wide.
Mature green foxtail.
Collar region: hairy ligule.
Green foxtail commonly occurs in cultivated fields, pasture, waste ground, landscapes and any open area with nutrient-rich soil.
Green foxtail is found throughout Missouri and the United States.
Giant foxtail also has a hairy ligule, but it is covered with hair on the upper leaf surface. Yellow foxtail has a hairy ligule but only a few sparse, long hairs along the base of the upper leaf surface. The stems of yellow foxtail are flat.
