Avena barbata (slender wild oat) is a winter annual grass (family Poaceae) that grows in nearly every grassland area of the state. It does well in sandy/poor soils, often on the road verges. It is one of the annual grasses that was introduced as a forage species and has replaced the native perennial grasses.

Cal-IPC Inventory rating: Moderate
