A Master Gardeners Own Native Garden.

In 2024, we’ve had another rainy winter after years of debilitating drought, and I’m tempted to think that it might be ok after all to put in a thirsty garden, a little thirsty garden, somewhere that would be easy to reach with a hose.  This thought is enticing, but it’s very far from reality. Climate scientists tell us that our Bay Area climate has been water-stressed far more often than it has been water-sufficient.  Drought is not done with us yet.

Besides, I love my drought-tolerant California native plants. For example, the sages in my garden keep bringing me back to reality with their beautiful gray-greens and purples, their various sizes and growing habits, and their unique aromas.  Even pruning them back at the end of the season is a joy, knowing they’ll reliably anchor my garden again in the spring.  

This year I took a chance and purchased a pound of California wildflower seeds.  I have no idea how well they’ll do, but in the fall I scattered them about, mostly in the backyard.  I can see that the phacelias and poppies have already sprouted, and I hope for pleasant surprises ahead.  In addition, I planted California fescues, St. Catherine’s lace, and yarrows on the low mounding backyard terraces that support the lemonade berry and ceanothus bushes.  Those expansive bushes are now in their sixth year here and show no signs of slowing down.  They’ve held up well against winds that took down one of my fences last winter.  I’m counting on them to continue persevering, no matter what the weather, and host the birds and insects that find their shelter compatible.  So far, I must say, we’re all doing fine together.

Prunus spp

Prunus
Organization

Large group of evergreen and deciduous shrubs and trees that includes many ornamental species as well as others that produce edible fruit.

Examples:

  • Apricot, nectarine, peach, and plum trees are all classified as having low-water use in Sonoma and Marin counties. Consult local nurseries for available types and specific growing requirements.
  • Carolina laurel cherry (P. caroliniana, 20-30’ x 15-20’) is an upright, evergreen shrub from North Carolina to Texas where it grows as an understory plant. Its small, white flowers in spring are followed by small black fruit. P. c. ‘Compacta’ (10-15’ x 6-8’) is a popular smaller form.
  • Hollyleaf cherry (P. ilicifolia, 10-25’ x 10-25’) is an evergreen shrub from central California to Baja California. Creamy white flowers in narrow spikes in late spring to early summer are followed by fruits that attract many species of birds. Can be used as a hedge or screen, as well as for erosion control.

Rhus spp

Lemonade Berry, Sugar Bush
Organization

Diverse group of resilient shrubs and trees, including several that are native to California, that provide form, foliage, and habitat value.

  • Lemonade berry (R. integrifolia, 4-20‘ x 4-20’) is native to coastal Southern California and Baja California. This evergreen shrub provides white-to-pink clusters of flowers in late winter and early spring followed by sticky, reddish fruits. Lemonade berry is more suitable for coastal climates, whereas sugar bush will also grow in hotter areas.
  • Sugar bush (R. ovata, 4-10’ x 4-10’) is native to dry slopes away from the coast in Southern California and Baja California. Similar to lemonade berry with more reddish flowers and leaves that are often folded down the center.
  • African sumac (R. lancea, 15-25’ x 20-30’) is an evergreen tree from South Africa with willow-like leaves and graceful weeping habit.

Note: The infamous poison oak was previously classified within the Rhus genus, but has since been reclassified to the more appropriate sounding Toxicodendron diversilobum.

California Lilac ceanothus variety with clusters of small, vibrant blue flowers and dark green leaves

Ceanothus spp & cvs

Ceanothus
Organization

Ceanothus is a group of fast-growing, evergreen shrubs that vary from groundcovers to small trees, many of which are native to California. They provide a spectacular display of flowers in spring that will attract a multitude of pollinators. Flowers are followed by seeds that provide food for birds. The clusters of tiny flowers range from white to deep violet. Plants perform best with good drainage and minimal irrigation once established. Some do best in cooler coastal climates, but many thrive in hotter inland climates. Pay close attention to the mature size when selecting ceanothus to ensure that it has sufficient space for its natural form.

Groundcovers: C. ‘Centennial’ (1’ x 8’), C. gloriosus var. gloriosus ‘Anchor Bay’ (2’ x 8’), C. griseus var. horizontalis ‘Diamond Heights’ (variegated, 1’ x 4’), C. griseus var. horizontalis ‘Yankee Point’ (3’ x 12’), C. maritimus (2’ x 6’).

Asclepias spp

Milkweed
Organization

Colony-forming, herbaceous perennials with several species providing important habitat and larval food sources for the monarch butterfly while attracting a diverse array of insects.

California milkweeds remain dormant during the colder months. Stems that emerge in April or May bear clusters of small, star-like flowers in summer followed by silky-tailed seeds that are dispersed by wind. A. fascicularis (narrow-leaved milkweed, 1-3’) is the preferred food source for monarch larvae. A. speciosa (showy milkweed, 2-4’) has larger, soft foliage, showier flower clusters, and is also a food source for monarch larvae. A. cordifolia (heart leaf milkweed, 1-2′) has heart-shaped leaves and is also a food source for monarch larvae.

Eriogonum spp

Buckwheat
Organization

Diverse group of flowering, evergreen shrubs and perennials and annuals found throughout the western United States. Most available in nurseries are native to California and generally prefer drier sites. Flowers colors include yellow, white, pink, and red and are held above foliage in umbels that dry over time and are popular in flower arrangements. Buckwheats provide pollen and nectar for bees and butterflies, larval food for butterflies, seeds for birds, and cover for many creatures.

Examples:

  • Santa Cruz Island buckwheat (E. arborescens, 3-4’ x 4-5’) densely mounded with white flowers.
  • Saffron buckwheat (E. crocatum, 1-2’ x 2-3’) with chartreuse-yellow flowers and pale leaves.
  • California buckwheat (E. fasciculatum, 2-3’ x 3’) and its low-growing cultivars such as E. f. ‘Warriner Lytle.’
  • Catherine’s lace (E. giganteum, 4-8’ x 6-10’) with delicate, white flowers and soft pale leaves.
  • Red-flowered buckwheat (E. grande var. Rubescens, 1-2’ x 2-3’) low-mounding perennial with rose-pink flowers, coastal bluff buckwheat (E. latifolium, up to 12” x 1-2’.)
  • Sulfur buckwheat (E. umbellatum, 6-18” x 1-3’) with intense yellow flowers and cultivars E. u. var. aureum ‘Kannah Creek’ and E. u. Var. ‘Shasta Sulphur’.

Festuca spp

Fescue
Organization

Large group of mostly cool-season, perennial, bunching or spreading grasses. Bunch grass varieties can be used as a no-mow lawn replacement, help to stabilize slopes, and have ornamental value. Festuca californica (California fescue, 1-2’ wide x 2’) prefers part shade and works wonderfully massed under the dry shade of native oaks. Festuca glauca (blue fescue, 1’ x 1’) is a small, clumping grass with bluish gray-green leaves. Festuca idahoenis (Idaho fescue, 1-2’ wide x 1’) also has bluish gray-green leaves and is more drought-tolerant and longer lived than blue fescue. Festuca rubra (red fescue) grows from rhizomes and has long, fine-textured leaves that lay over to form a pleasing drift effect as a no-mow lawn.

Start with your soil!

which will probably need some help. Contact your local Master Gardeners for ideas on how to improve it.

3

Visit other gardens for inspiration.

Every year I find great inspiration from visiting other people’s gardens – seeing what works and what hasn’t, talking to the gardeners who are actively creating their beautiful gardens. With the climate changing as rapidly as it is now, we need all the information we can find.
