With Spring officially upon us, many people are ready for planting in their gardens. Time to go outside with some of the pent-up energy we’ve been harboring and take it out on the dirt. The rewards can be beautiful!
While in many parts of California our gardens can have blooming plants virtually year-round, springtime is, of course, always particularly associated with floral displays in our gardens. This holds true with the surrounding wild landscapes too, and at Madrone Landscapes, we routinely sing the praises of our California native flora.
Other regions across the world share similarities with our California climates. They are known as Mediterranean-type ecosystems or “MTEs.” MTEs, with their characteristic climatic regimes of mild wet winters and warm and dry summers, they occur in just five regions of the world: California; Central Chile; the Mediterranean Basin; the Cape Region of South Africa; and Southwestern and South Australia. There are abundant examples of plants suitable for our Central Coast gardens that are native to these other regions. Let’s consider Five of these plants that may not be that well-known but might be great for your garden:
Starting close to home, there is the often-overlooked California Native Cornus sericea (Cornus stolonifèra), or Creek Dogwood. It is a deciduous shrub also known as Redtwig for its distinctive red stems, keeping it interesting through the winter. Creek Dogwoods can grow 8–12’ high and wide, and have clusters of creamy white flowers, spring to summer. The form is open, and leaves are 1.5–2.5 inches long and light green—brilliant red in fall. It is hardy to well below freezing and prefers partial shade. Branches will root if allowed to touch ground, and roots will spread. Redtwigs love moisture, are fire-resistive, and require medium irrigation in the dry months.

When one thinks of aromatic leaves, used in cooking, Laurus nobilis, or Sweet Bay, is often the first to come up. Also called Bay Laurel or Grecian Laurel, this small tree is also a versatile evergreen tree for Central Coast landscapes. Growing 20–30 ft. tall to 20 ft. wide, Sweet Bays produce small yellow flowers in Spring, followed by deep purple berries. Best known for their fragrance, they are deer-resistant, fire resistive, and attract birds. Preferring fertile, well-drained soils, they are low water users once established. The variety “Saratoga” is best for use as a tree, but the species can also be used as a background or for screen shrubs.
South Africa Aloe striata, or Coral Aloe, is one of many aloes native to South Africa. This beautiful succulent has found home in many a garden in the milder micro-climates (hardy to 25 degrees Fahrenheit) of North San Luis Obispo County, and throughout the Coastal climates. It grows to be a 2 ft. wide rosette with broad, pale green, nearly toothless, flat leaves. The brilliant coral-pink-to-orange flowers occur in spring on branched clusters up to 3 ft. tall. Plant in full sun in well-drained soil. Coral Aloes are fire- and deer-resistive, require minimal water, and attract hummingbirds.
Known for its graceful, weeping form and light green, evergreen foliage, Maytenus boaria, or Maytens Tree, is a unique and small specimen tree for much of the Central Coast. Hardy to 20 degrees Fahrenheit, the Mayten Tree grows to over 30 ft. and has long, pendulous branchlets hanging down from its branches. The tiny spring flowers are pretty inconspicuous, and the leaves are 1–2 inches long. They are fire- and deer-resistive and want full sun and ample summer water. They tend to branch on the side and may need guidance through pruning. Suckers are discouraged through deep watering, and Maytens Trees can produce beautiful lighting effects in the landscape.
People native to Australia have have made good use of Grevilleas since time immemorial. With over 350 species of Grevilleas—from virtually flat ground covers to soaring trees—their uses range from building furniture to making drinks from the nectar. One favorite landscape plant is Grevillea “Canberra Gem,” also known as Spider Flower. This shrub has a graceful, open form from about 8 ft. tall to 12 ft. wide. The bright green leaves are needlelike and prickly, making for a good barrier plant. Flowers are red clusters from early spring and intermittently at other times. Not only deer-resistive, this and other Grevilleas attract butterflies and birds with their nectar and seeds. Canberra Gem grows in a variety of soils from clay to sandy loam and is quite rough tolerant, preferring occasional deep soakings and good drainage. Hardy to about 20 degrees Fahrenheit.
It’s that time of year again: Summer! The sun can do a lot
of good for your plants in the garden, 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 ovatifoliais 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 which will add sculptural interest to any summer garden!
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 which 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 which 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.
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 which 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 on top of cramped conditions and heat!

It’s 2019! If you’re thinking about landscaping this year, keep sustainability in mind. So, what does that mean? Here’s how author and landscape architect Owen Dell describes a sustainable landscape:
“Imagine a garden that rarely needs pruning, watering or fertilizing. One where natural controls usually take care of pest problems before the gardener even becomes aware of them. A peaceful garden where the sound of blowers, power mowers, or chain saws never intrudes. Imagine a garden that also serves as a climate control for the house, keeping it cool in summer and warm in winter; a garden that traps rainwater in an attractive streambed to deeply irrigate the trees and recharge the groundwater; one that provides habitat for wildlife and food for people. Imagine a garden that truly works. This is the sustainable garden—not barren or sacrificial, but as lush and beautiful as any other without all the struggle and waste.”
In considering your landscape project, good planning is vital. Creating a design can save you time and money by coordinating your efforts to make the most of your space, time, and budget. What are the uses you’d like to incorporate? Hardscape areas like patios, play areas and structures, or water features can all make your property work for you. When contemplating how you’ll be using the areas, think about the materials. Are they sustainably produced and sourced? Consider the Embodied Energy impacts, which include everything it takes to have a material available for your use.
Any discussion of California landscaping will include irrigation. Irrigation systems need to be accurate, low-flow and timed appropriately to keep plants healthy and thriving. When thinking about the plants, whether shrubs, trees, veggies or turf, think about conserving resources, especially over time. California Native Plants can often be very good choices to include in your design. Local native plants are often the most climate compatible and lowest maintenance choices.
These are just a few of the sustainable principles you can use as guidelines to maximize your landscape efforts. And in doing so, take advantage of living in the incredible region of California’s Central Coast. Make time to get out and enjoy yourselves in your gardens. They offer unique opportunities to unwind and relieve stress. Reconnect with things natural, beautiful and up close. Even in our own gardens we are connected in a very real way to the larger landscape, and how we have a responsibility to sustain the health and beauty of our beloved Central Coast. Let’s make it work for the long run.
