Recommended Shade-Loving Native Perennials for the Central California Foothills and Coastal Mountains

About 25 percent of the plant species native to North America are at risk of extinction. You can help reverse this trend by planting great native plants in your garden.

California has tremendous ecological and biological diversity. It contains offshore islands and coastal lowlands, large alluvial valleys, forested mountain ranges, deserts, and various aquatic habitats.

California is divided into 13 main ecological regions and 177 sub-regions. Unique in topography, soil depth, pH, elevation, light, and hydrology, each region provides a rich variety of ecological habitats, supporting many native plant species.

The Central California Foothills and Coastal Mountains region is characterized by its Mediterranean climate of hot dry summers and cool moist winters, and an associated vegetative cover comprising primarily chaparral and oak woodlands; grasslands occur in some low elevations and patches of pine are found at high elevations. Surrounding the lower and flatter Central California Valley, most of the region consists of open low mountains or foothills, but there are some areas of irregular plains and some narrow valleys. Large areas are ranchland and are grazed by domestic livestock. Relatively little land has been cultivated, although some valleys are major agricultural centers such as the Salinas Valley or the wine vineyard centers of Napa and Sonoma Valleys. Natural vegetation includes coast live oak woodlands, Coulter pine, and unique native stands of Monterey pine in the west, and blue oak, black oak, and grey pine woodlands in the east.

The Central California Foothills and Coastal Mountains encompass:

  • The Tuscan Flows ecoregion is a gently southwest-sloping plateau with some steep canyons and a few steep volcanic cones.
  • The Northern Sierran Foothills ecoregion consists of moderately steep to steep mountains and hills at the western foot of the northern and central Sierra Nevada.
  • The moderately steep hills and low mountains of the Southern Sierran Foothills ecoregion represent a transition from the Central California Valley to the Sierra Nevada.
  • The Camanche Terraces, on gently sloping to moderately steep hills and dissected terraces along the eastern edge of the Central California Valley downslope from the central Sierra Nevada foothills.

  • The Bay Flats ecoregion includes the near-water flats around San Pablo Bay in the north and those at the southern end of San Francisco Bay.
  • The low-elevation Suisun Terraces and Low Hills ecoregion surrounding Suisun Bay, upland from the lower part of the Delta. A few low hills occur, such as the Portrero Hills and Montezuma Hills.
  • The East Bay Hills/Western Diablo Range ecoregion consists of the East Bay Hills to the east of the Berkeley-Oakland-Hayward urban area, Mount Diablo and the Black Hills area farther east, as well as the hills of the western Diablo Range.
  • The San Francisco Peninsula ecoregion occurs at the northern end of the peninsula, with a climate affected greatly by marine influence.
  • The Bay Terraces/Lower Santa Clara Valley ecoregion is an urbanized area on alluvial plains that wrap around San Francisco Bay between the East Bay Hills ecoregion on the east and the Leeward Hills ecoregion to the west.
  • The Livermore Hills and Valleys ecoregion consists of the Livermore, Amador, and San Ramon Valleys and the low hills that surround them.
  • The Upper Santa Clara Valley ecoregion is a low-relief alluvial plain in the upper Santa Clara Valley, including the San Benito Valley.
  • The coastal Monterey Bay Plains and Terraces ecoregion occurs on alluvial plains and terraces that wrap around Monterey Bay.
  • The Leeward Hills ecoregion is an area of mountains and hills with rounded ridges, steep and moderately steep sides, and narrow canyons.
  • The Gabilan Range ecoregion contains steep mountains between the San Andreas Fault on the northeast and the Salinas Valley on the southwest.
  • The Diablo Range ecoregion includes mountains with rounded ridges and steep to moderately steep sides, along with narrow canyons and valleys.
  • The Eastern Hills ecoregion includes the low, steep mountains and foothills on the eastern side of the Diablo Range, including the Panoche, Ciervo, and Kettleman Hills, and Avenal Ridge at the southern end.
  • The Pleasant Valley/Kettleman Plain ecoregion contains disjunct small valleys and relatively flat plains that contrast with the steeper, adjacent hills.
  • The Temblor Range/Elk Hills ecoregion contains steep mountains and moderately steep hills around the Temblor Range and the lower, gentler Elk Hills.
  • The Grapevine Transition ecoregion is an intermediate region between the Southern California Mountains and Central California Valley.
  • The Tehachapi Foothills ecoregion consists of moderately steep to steep mountains and hills on mostly granitic terrain.
  • The Salinas Valley ecoregion includes gently sloping alluvial plains, stream terraces, and nearly level floodplains of the Salinas Valley.
  • The Northern Santa Lucia Range
  • The Santa Lucia Coastal Forest and Woodland ecoregion is a near-coastal zone that stretches from Carmel Bay in the north to Salmon Creek in the south.

According to the U.S. Forest Service, Invasive species have contributed to the decline of 42% of U.S. endangered and threatened species, and 18% of U.S. endangered or threatened species. Invasive species compete directly with native species for moisture, sunlight, nutrients, and space. They displace and alter native plant communities, degrade wildlife habitat and water quality, and potentially lead to increased soil erosion.

The federal government has estimated that nearly 25 percent of the 20,000 plant species native to North America are at risk of extinction, many of these through habitat loss. You can help reverse this trend by planting great native plants in your garden.

A plant is considered native if it has occurred naturally in a particular region or ecosystem without human introduction. There are many benefits to growing native plants.

  • First, these plants are better adapted to soils, moisture, and weather than exotic plants that evolved in other parts of the world. They need fewer fertilizers, and pesticides or use less water.
  • Second, they are unlikely to escape and become invasive, destroying natural habitats.
  • Third, they support wildlife, providing shelter and food for native birds and insects, while exotic plants do not.

Here is a list of California native perennials that are well-suited for plantings in shady gardens of the Central California Foothills and Coastal Mountains.

  • Never collect native plants from the wild as it will deplete natural ecosystems. 
  • When possible, plant species grown straight from local seed sources. These native originals are the best choice, as they co-evolved with specific wildlife, which supports migration, breeding, and other seasonal interdependencies.
