Danthonia californica (California Oatgrass) - A clumping nearly evergreen native perennial bunch grass with a dense tuft of short flattened green leaves 4 to 10 inches tall and tall slender stalks 2 to 3 feet tall bearing a few (1-5) spiklets holding 3-8 florets with reddish-purple protruding anthers. Plant in full sun to moderate shade and water regularly, occasionally to very little. It tolerates a wide range of temperatures; from the heat of the desert to well below freezing (-30°F) and is drought-stressed deciduous. California Oat Grass comes from generally moist, open sites and shaded glens in meadows and forests across a wide range of western coastal regions of North America from elevations of 500ft-7000ft. In California, where it can be found along the coast from Ventura County north to Canada and in the inland mountain ranges from the Peninsular Range in San Diego county north along the western edge of the Sierra Nevada and Cascade ranges. It is also found in Chile in South America. It is an important dominant component of coastal prairies and is known to tolerate regularly disturbed ecosystems as a colonizing species - this makes it particularly useful as a garden plant! To range managers it is known as a an "ice-cream plant" because of its palatability to livestock. This speaks to its durability, tolerating trampling and traffic and little to regular irrigation. There is a great article in the June 2009 issue of Pacific Horticulture showing this grass used in a mixed meadow at Sea Ranch titled A Wind-blown Garden on a Sea Ranch Bluff. The name for the genus honors Étienne Danthoine, a late 18th century to early 19th century French botanist and agrostologist from Marseilles who had written articles on grasses.  This information is based on research conducted about this plant in our nursery library and from reliable online sources. We also take into consideration observations of it in our nursery of crops, as well as of plants growing in the nursery's garden and those in other gardens we have visited. We will incorporate comments received from others and welcome getting feedback from anyone who may have additional information, particularly if it includes cultural information that would aid others in growing Danthonia californica.
