Four Winter-hardy Plants for your California Central Coast Landscape
Nandina ‘Fire Power’ is a great evergreen shrub that has year-round interest. It is especially beautiful in the fall and winter: the leaves turn a deep red with cold weather.
Arctostaphylos ‘Howard McMinn’ is a low-maintenance, low water-use shrub. Manzanitas are striking year-round thanks to their evergreen leaves and gorgeous red bark, but their dainty winter blooms really give them another dimension.
Here on the central coast, we don’t typically have freezing temperatures, and we have fewer plants that die back or go dormant during these colder, wetter months. During the winter months when nothing else in the garden is showing its colors, here are four of our favorite plants to steal the show.
Sempervivum (Hens and Chicks) This cold-hardy succulent comes in a variety of colors and can be planted in rocky places with very little soil. We love the look it creates when you stick them in cracks and crevices of stone walls or walkways.
Rosmarinus officinalis ‘Irene’ like Manzanitas, Trailing Rosemary is low-maintenance and low water use. When planted on top of retaining walls and allowed to drape over, they add drama to your garden, while their scent and seasonal flowers give them an added edge over some of the other trailing plant materials.

Colorful natives to brighten up landscape design for the Central Coast
Madrone began over 40 years ago with the idea that a company dedicated to sustainability and the use of California native plants could be a great combination — beautifying human habitats while serving to “heal the scars” of development. The garden and landscape performance benefits of this approach prove their merit.
Over the decades, the functional benefits of native plants have become universally recognized and honored. They also remind us of our locale’s singular natural beauty and why we need to protect our region from biological decline.
We’ve gathered five of our favorite California native accent plants that don’t require a lot of care, such as water and fertilizer. These colorful beauties can also be incorporated into many different garden settings throughout the Central Coast. They are especially useful in the small, forgotten spaces in the landscape.
Erigeron glaucus, Seaside Daisy
This low, evergreen perennial thrives in borders and nooks, full sun for Coastal gardens and partial shade inland. Native from Santa Barbara north to Oregon. The long bloom season, Spring through summer, can be extended by “deadhead” pruning, which fortunately does not require wearing tie-dye clothes. There are several varieties available, including ‘Wayne Roderick’ (or WR) and ‘Cape Sebastian’. They form thick mats, 6-10 inches high, spreading 2-3 ft., and can take frost and high temperatures well over 100 degrees F.
Pacific Coast Hybrid Iris
Walking in a redwood grove or a coastal mixed evergreen forest, one can occasionally happen on a Pacific Coast iris popping up through the low understory. Best grown in partial shade unless close to the Coast, these exquisite, delicate-looking, springtime bloomers are frost-hardy and relatively drought tolerant. They make excellent informal borders or accents among other shady perennials or in rock gardens.
Heuchera species, Coral Bells
When rock gardens come to mind, it is hard to beat coral bells. We love the way their bright-colored flower stalks rise above the evergreen foliage! The native species often are found in the nooks and crevices among stone outcroppings from San Luis Obispo County north through Coastal Washington. The flowers range from white through many shades of pinks and reds, making great combinations with other small perennials, shrubs, and grasses.
Dudleya brittonii, Britton Dudleya
A succulent originating on the bluffs of coastal Baja California, Britton dudleya is a beautiful accent plant that forms a single, low, chalky gray-white rosette to 12-14″ diameter, and in well-drained soil, thrives on neglect. Its flower stalks rise 2 feet or more, turning red with pale yellow flowers. It loves full sun on the Coast and some shade and protection from the frost inland. Britton dudleya is very popular and makes a striking complementary statement to many California gardens.
Ceanothus glorious ‘Anchor Bay’ and Ceanothus ‘Centennial’
A garden needing larger plants to act as ground covers might include these two low-spreading shrubs for fast establishment and beautiful blue spring flowers. Centennial is very low, 8-12″ high, spreading to 6 feet or more. ‘Anchor Bay’ is taller, up to 3 feet in height, and spreading 6 feet. ‘Anchor Bay’ is one of the most widely used ground cover species of Ceanothus, performing best in full sun on the coast and in partial shade inland. ‘Centennial’ also prefers some shade inland and both require well-draining soil.
From Santa Maria to San Luis Obispo to Paso Robles and beyond, these drought-tolerant natives will liven up your outdoor sanctuary, with minimal upkeep.
It’s that time of year again: Summer! The sun can do a lot of good for your plants in your landscape, but not everything can handle the heatwave blaze. Here are 8 back-bone plants to rely on when the temps are high and the air is dry.
Agave ovatifolia (shown above) is family to the famed Century Plant which is prized for its durability and form. This variety, known as Whale’s Tongue Agave, stays much more compact, and has attractive blue/gray foliage with small teeth along the margins of each succulent leaf. A single, dramatic flower spike blooms at maturity. It is a sun-loving, drought-tolerant succulent that will add sculptural interest to any summer display.
Another California Native and reliable performer is Ceanothus. Known by many as California Lilac, Ceanouthus griseus horizontalis ‘Yankee Point’ is a specific groundcover variety that will tenaciously fill empty space in your landscape. Great for erosion control, this winter bloomer adds year-round interest with its small blue flower clusters. A main attraction for pollinators, this plant will not only tolerate drought and heat, but will help stabilize ecosystems.
Chondropetalumtectorum is a South African native reed grass which not only adds a sleek texture to your landscape but can endure almost any challenge that the Central Coast presents. This plant will take on searing heat, cold down to 20 degrees, and is one of the closest we’ve found to the ‘no maintenance’ dream. This one is bombproof and beautiful.
Kniphofia, also known as Red Hot Poker plant, is a striking option for foreground plantings, containers, and against walls. Its attractive blade-shaped leaves offer a clean texture during winter months, while the spring and summer blooms have a striking ombre color effect. Also native to Mediterranean South Africa, Kniphofia has an exotic look that maintains its beauty even in the blaring summer heat.
Our California native deer grass, Muhlenbergia rigens, is a drought-tolerant champion of the landscape. Attractive seed heads in the Spring give this larger grass an endearing tousled look which works in almost any setting, as a background, accent, or mass. Up to 5’ tall and wide, this grass stands out with its substantial size and will pull through despite the hottest California summer.
Jerusalem Sage, or Phlomisfruticosa, is a unique plant that offers many sought-after characteristics. This plant has the size and form of a sage, but the peach-fuzz foliage is true green in contrast to the silver of our native Sage varieties. Bright yellow flower whorls are non-toxic and stand out in the garden. Jerusalem sage is a sun-loving and solid choice for inland summers in areas such as Atascadero, Paso Robles, and San Luis Obispo.
Salvia x ‘Allen Chickering’ is another stunning California Native which loves arid climates and sunshine. This member of the Sage family showcases characteristic gray/green leaves and attractive, fragrant flower whorls. A top performer in the landscape, Allen Chickering Sage will attract hummingbirds and butterflies while deterring deer, making it a top choice for the warm season.
Creeping thyme is a dainty groundcover that adds charm to patios, walkways, and borders. Thymus serpyllum ‘Pink Chintz’ exhibits a showy bloom during the Spring and Summer months, with bright pink flowers speckled against the ashy green leaves. This Mediterranean herb has a distinctive aroma and can tolerate light foot traffic in addition to cramped conditions and heat.
