DESCRIPTION:
Yellow foxtail is a summer annual grass and is common in northern California growing areas. First leaves are usually parallel to the ground. Mature plants are 1 to 3 feet (30 - 90 cm) tall, with branching and some spreading at their bases. Leaf blades are 4 to 15 inches (10 - 38 cm) long, and most have a spiral twist. Flower heads are dense spikes with yellow to reddish bristles. The ligule of yellow foxtail is a fringe of hairs and there are no auricles. There are no hairs on the leaf sheath margin below the collar.
