About Needle Grass (Stipa cernua) Nodding Needle Grass (Nassella cernua) is a native grass that grows in many parts of California, primarily in the Coast Ranges from Tehama County southward at elevations from sea level to 5,000 ft. It is fast growing and moderately long-lived. It grows in an upright form to a height of 3 feet, with active growth during the spring. Leaves are medium green and deciduous. There have been some taxonomic changes related to this genus (Needlegrass) over the years, and some sources may refer to it as Nasella. The Stipas generally have been a major component of California's native grasslands. In the garden it is best used in small patches between chaparral or sage scrub species and mixed with various perennial herbs and annuals.
