Oatgrass – California

California Oatgrass is a native bunchgrass that is dispersed throughout the western regions of North America, between California and Canada, as well as in some parts of South America.  It is often located throughout coastal prairies, around the outside of wetlands, and in a variety of other vegetative communities.  In Oregon, California Oatgrass is found on both sides of the Cascade Mountain range.  It is a short-lived perennial that grows between 1 and 2 ½ feet tall in areas of full sun.  This grass has adapted to a broad variety of growing conditions.  It produces self-pollinated seeds that drop from small flowers, which never open, and can handle terrain stress and ecosystem disturbances.  It will establish in medium or fine textured soil and has a moderate drought tolerance.  California Oatgrass is a slow-growing grass but is distinctive in that it will stay green all year long.
