California oatgrass (Danthonia californica) is a native perennial bunchgrass that's useful in many landscaping applications. It is found in moist meadows and open spaces in Central and Northern California. It grows in dense tufts that can reach 3 ft in height. Flower spikelets appear between May and July. In the garden, California oatgrass can be used as an ornamental grass or it can serve as a lawn replacement that stands up to foot traffic when mowed short. It's also good for erosion control and soil stabilization.

Although it can adapt to a range of conditions, California oatgrass does better in cool, moist environments than in hot, dry landscapes. It has a high fire resistance rating and can be planted as a firebreak. This grass is a host plant for multiple skipper butterfly species. The seeds provide food for birds and small mammals.
