DESCRIPTION:
Barnyardgrass is a summer annual grass that germinates from seeds from late winter or early spring throughout the summer. Stems of young barnyardgrass plants often grow outward along the ground before turning upward. Stems are flattened near the base. This weed is the only common summer grass that has no hairs or membranes at the collar region and lacks a ligule. Flower heads are extremely variable, but they often droop slightly with lower flower branches further apart than upper ones.
