Native Plants for SLO County Yards
Updated: 2 days ago
The hills around San Luis Obispo County plant themselves every winter and bloom every spring without anyone turning on a hose. That is the entire argument for native plants in San Luis Obispo County yards. They evolved for this exact combination of winter rain, summer drought, coastal fog, and inland heat, and once established they ask for very little.
The catch is that "native to California" covers everything from redwood forest to Mojave, so the list below is specific to what actually works here, from the Cambria coast to the ranch country east of Paso Robles.
COAST · VALLEYS · NORTH COUNTY
Three climates, one county
Before the plant list, a quick reminder that SLO County is really three growing environments.
The coast (Cambria, Cayucos, Morro Bay, Los Osos, Avila, Pismo, Oceano, the Nipomo Mesa) is cool, foggy, often windy, and rarely freezes. Plants here want to handle salt and wind more than heat.
The valleys (San Luis Obispo, Edna Valley, Arroyo Grande, Nipomo's inland side) are the sweet spot: mild, with warm afternoons and cool nights, and a light frost in winter. Almost everything on this list grows here.
North County (Paso Robles, Templeton, Atascadero, Santa Margarita, Creston, San Miguel) is hot in summer and cold in winter, with real frost. Plants here want heat tolerance and cold hardiness both.
Our guide to Central Coast weather town by town explains why a plant that thrives in Los Osos can struggle in Paso. Match the plant to the zone and most of the work is done.
WHAT TO PLANT
The list, by category
Trees and large shrubs
Coast live oak. The signature tree of the county. Slow, long-lived, evergreen, and the reason so many neighborhoods in SLO, Atascadero, and Templeton feel the way they do. Never water an established oak in summer.
Toyon. An evergreen shrub or small tree with red winter berries; handles coast and inland, deer mostly leave it alone. One of the best all-purpose screening plants in the county.
Western redbud. Deciduous, magenta bloom in early spring on bare wood, happiest in the valleys and North County.
Coffeeberry. Dense, evergreen, deep green, tolerant of shade and sun, and useful as an informal hedge in any zone.
Catalina cherry and hollyleaf cherry. Fast evergreen screens for larger lots.
Blue elderberry. For the wilder corners of a country property; birds love it.
Mid-size shrubs: the workhorses
Manzanita. Many species, from ground covers to small trees, with smooth red bark and winter flowers. Los Osos even has its own rare species, the Morro manzanita, which is protected where it grows. Choose the variety for your zone; some are strictly coastal.
Ceanothus (California lilac). Blue bloom in spring, evergreen, fast, and beloved by bees. Coastal forms handle fog and wind; inland forms handle heat. Do not water in summer.
Sages. Cleveland sage, black sage, purple sage, white sage. Fragrant, silver-green, and deeply drought tolerant. Cleveland sage in particular is a garden staple from Nipomo to Paso.
California buckwheat and seaside buckwheat. Pale pink summer flowers that age to rust; the backbone of coastal scrub and excellent on the Mesa and the bluffs.
Coyote brush. Tough, evergreen, and unbothered by wind or salt. Choose a prostrate form for a ground cover on exposed coastal lots.
Bush monkeyflower. Orange, yellow, or red flowers over a long season; likes some afternoon shade inland.
Fremontodendron (flannel bush). A big, dramatic yellow bloomer for North County slopes. Never water it once established.
Perennials and color
California poppy. Sow seed in fall, let it self-sow forever.
Lupine. Annual and perennial forms; the blue drifts on the hills in April.
Yarrow. White or colored, tough, handles some foot traffic, a good lawn edge.
Penstemon. Foothill and Margarita BOP penstemon are two of the best for the valleys and North County.
California fuchsia. Red-orange flowers from late summer into fall when little else is blooming; hummingbirds depend on it.
Seaside daisy. Lavender flowers, low, perfect for the coast.
Hummingbird sage. For dry shade under oaks, which is one of the hardest spots in any yard.
Douglas iris. Spring bloom, coastal and valley shade.
Grasses and ground covers
Deer grass. Large clumps, architectural, moves in the wind. Handles every zone.
Purple needlegrass. The state grass, fine-textured, good for meadows.
Blue fescue and Idaho fescue. Compact, silver-blue, tidy.
Yarrow and creeping manzanita for a walkable ground cover.
Dune sedge and beach strawberry for coastal sand.
BEFORE YOU DIG
The honest notes: deer, gophers, wind, and fire
Native does not mean pest-proof. Deer browse ceanothus, redbud, and young oaks in Cambria, the hills above SLO, and most of North County; toyon, sages, manzanita, and coyote brush are more reliably left alone. Gophers eat roots without prejudice, and on a rural lot you will plant in wire baskets or accept some losses. We cover the whole cast of characters in deer, gophers, and ground squirrels: living with Central Coast wildlife.
Wind on the coast and the Nipomo Mesa favors low, stiff plants like buckwheat, coyote brush, and coastal sage over anything tall and brittle. And in fire zones, natives still burn. Keep the woody shrubs away from the house, favor low irrigated plants near the walls, and prune out dead material every year, as described in defensible space for SLO County homeowners.
LOCAL NURSERIES
Where locals actually buy them
Native plants are easier to find on the Central Coast than almost anywhere in the state. Several independent nurseries in the county specialize in or carry a deep selection of natives, the San Luis Obispo Botanical Garden at El Chorro Regional Park is a living catalog of what grows here and holds plant sales, and the local chapter of the California Native Plant Society runs sales and walks that are worth an afternoon. Ask a nursery which plants were grown from local stock; those are the ones that thrive.
If a plant grows on the hill you can see from your kitchen window, it will grow in your yard. Start there.
Your next step
Pick three plants from the list for your zone, plant them this fall, and see how they do before committing to a whole yard. If you are preparing a home for sale, a few well-placed natives in the front yard are among the highest-return improvements on the Central Coast, and we are glad to suggest which ones read best in your town. For the design side, see our companion post on drought-tolerant landscaping that still looks like the Central Coast.
