California Hairgrass (Deschampsia cespitosa ssp. holciformis) is one of three recognized subspecies of this native bunchgrass. Ssp. holicformis grows in Central and Northern California, primarily along the coast and in the Coast Ranges. It is found in coastal prairie habitat and mountain meadows, along with other native grasses such as Fescues (Festuca spp.) and Needlegrass (Stipa spp.). It is most often found in moist to very wet areas such as freshwater or saltwater marsh, riparian areas, and woodland/forest habitats at elevations up to 4,500 ft. It is said to be deer-resistant. Although native to the central/northern coast, it reportedly performs well in coastal areas of southern California. It does not do well in hot, dry inland areas. This subspecies is somewhat less commonly seen in the garden compared with the species, but it would be a good choice for gardens in its native range.
