Why Bay Area natives suit dry summers
The Bay Area has a Mediterranean climate: mild, wet winters and long, dry summers with little or no rain from roughly late spring into fall. Native California plants evolved with this pattern. Many grow in the cool, wet season, bloom in spring, and slow down or go dormant in summer. That is different from a plant that needs steady moisture all year, which is why natives are such a good fit when water is limited.
Microclimates matter. Coastal fog, inland heat, hillside exposure and soil type (clay, serpentine, sand) can all change which plants thrive. Choose by your own conditions rather than by “Bay Area” alone.
Shrubs and small trees
- Toyon (Heteromeles arbutifolia): an evergreen shrub or small tree with white summer flowers and red winter berries that birds eat. It can reach roughly 8 to 15 feet or more.
- California lilac (Ceanothus spp.): evergreen shrubs, many with blue spring flowers. Popular selections include ‘Concha’ and ‘Ray Hartman’; others are groundcovers. Many dislike summer water, especially in heavy soil.
- Manzanita (Arctostaphylos spp.): diverse evergreen shrubs with smooth red bark and winter-to-spring flowers that hummingbirds visit. Choose a form suited to your site.
- Coyote brush (Baccharis pilularis): a tough shrub or groundcover that is useful for habitat and erosion control.
- Coffeeberry (Frangula californica): an evergreen shrub with berries for birds, more adaptable to a bit of shade.
- California buckeye (Aesculus californica): a small tree that drops its leaves in summer and thrives with winter rain.
Perennials and wildflowers
| Plant | Notes |
|---|---|
| Cleveland sage (Salvia clevelandii) | Aromatic; blue-violet flowers; popular with hummingbirds and bees |
| California fuchsia (Epilobium canum) | Late-summer red-orange flowers for hummingbirds |
| Sticky monkeyflower (Diplacus aurantiacus) | Orange flowers in spring; tolerates dry slopes |
| Buckwheat (Eriogonum spp.) | Excellent for pollinators; many species |
| Yarrow (Achillea millefolium) | Tough and low-maintenance |
| California poppy (Eschscholzia californica) | Reseeds in sunny, lean soil |
| Hummingbird sage (Salvia spathacea) | Does well in dry shade, such as under oaks |

Grasses and lawn alternatives
- Deer grass (Muhlenbergia rigens): a large clumping grass that handles a range of conditions.
- Purple needlegrass (Stipa pulchra, now often Nassella pulchra): California’s state grass, a graceful bunchgrass.
- California meadow sedge (Carex pansa): a low sedge sometimes used as a lawn replacement that can be mowed or left natural.
Native bunchgrasses and sedges generally look best with limited summer irrigation and can reduce overall water use compared with conventional turf.
When and how to plant
Fall is the traditional planting season for natives in the Bay Area. Planting from roughly October through winter lets roots grow with seasonal rains before summer, and often means less hand watering. Spring planting is possible but demands more summer care.
- Give new plants regular water through their first summer or two, then taper off.
- Group plants by water need.
- Choose spots with good drainage; many natives suffer from root diseases in wet, warm soil.
- Add a few inches of mulch, keeping it away from the stems, and consider drip irrigation for the establishment period.
Watering and oak caution
Many natives are adapted to dry summers and can be harmed by frequent summer watering. This is especially important near native oaks, which are sensitive to summer irrigation and can be affected by root diseases when the soil is wet and warm. If you have oaks, keep the area beneath them as dry as possible in summer and ask a local arborist or native plant nursery for advice.
Note the difference between a plant that tolerates summer drought (typical of natives) and one that survives a multi-year drought without extra water. Even tough natives can suffer in prolonged drought, so check them during extreme dry spells.
Resources
Local native plant nurseries, California Native Plant Society chapters, and the Calscape database (which suggests plants by address) are useful tools for narrowing your choices. San Francisco and other Bay Area cities and water districts also publish recommended plant lists and lawn replacement programs, so check what applies where you live.

Frequently asked questions
What are the best drought tolerant plants for the Bay Area? Toyon, ceanothus, manzanita, sages, buckwheat and bunchgrasses are standard choices, with the best picks depending on your microclimate and soil.
Do native plants need watering? Yes, during establishment. After that, many need little or no summer water, though some benefit from occasional deep watering in extreme dry spells.
When should I plant natives in the Bay Area? Fall is generally ideal, as winter rains help roots establish.
