This is the TRUE Carex tumulicola, the foothill sedge, not to be confused with the so called Berkeley sedge which is correctly identified as Carex divulsa and is non-native AND invasive.  Foothill sedge has a wide distribution in California and north to Washington.  A tough and adaptable tufted evergreen growing 12 inches (or more) tall and spreading slowly by underground rootstocks. Useful as an informal groundcover under shrubs or trees, for a meadow planting or for soil stabilization where the spreading roots help control erosion.  Best with some shade unless right along the coast.  Responds to water but is able to tolerate periods of dryness.
