Agrostis avenacea (Pacific bentgrass) is a perennial grass (family Pocaceae) commonly found throughout northern California and San Diego County. This weed easily outcompetes native vegetation. Pacific bentgrass inhabits open, disturbed, often moist places to 300 m elevation. It is especially invasive in vernal pool habitat in the San Diego area.
