Interesting Plants to Update your Garden

Tired of seeing the same plants in your garden and everywhere else? Feel like changing things up a bit? With this question in mind I’ve turned to my fellow landscape designers to see what plants they are using these days so that every garden they design doesn’t look the same. You can have too much of a good thing.

One thing I know for sure is that I don’t want to recommend a plant that hasn’t been shown to be a reliable grower in a variety of conditions. Sometimes the latest and greatest plant introduction turns out to be a dud. Other times a new cultivar of an old favorite hits a home run. Here are some oldies but goodies and new plants to add to your garden.

 

Loropetaum ‘Jazz Hands Dwarf PInk’

Loropetalum ‘Jazz Hands’ is getting the nod from everyone who’s grown it. If you love the deer tolerance, low maintenance. moderate watering and toughness of regular Chinese Fringe Flower this showy dwarf variety is even easier to grow. Staying low and tidy Jazz Hands Dwarf Pink has cool purple foliage with a cranberry undercurrent and hot pink blooms. It looks great combined with Jazz Hands Dwarf White. Local wholesale nurseries are growing it so it’s readily available.

Speaking of local sources for plants, we live in one of the prime growing areas for landscape plants. I recently learned that one of my favorite plants Canyon Snow Pacific coast iris is going through a difficult time. Seems it’s become less vigorous than the other colors in the Canyon series and the growers are working to improve their stock. We need to count on a plant’s performance. There’s enough other issues to deal with in our gardens without starting with a wimpy plant.

Cistus variegata ‘Mickie’

Rockrose have always been favorites in the low water use garden. There’s one with a low, mounding habit that hugs the ground and creates a super colorful accent to the sunny garden. With brilliant gold leaves splashed in the center with green this variegated cistus hybridus called ‘Mickie” is hardy in winter, grows only 14-18 inches tall and spreads to about 2 feet wide. Perfect for containers or smaller gardens.

If you like to include California native plants in your garden Woolly Blue Curls or trichostema lanatum has been shown to be reliable in the garden if given full sun, good drainage and little fertilizer or amendment. Group similar plants and forget about them. They bloom from late spring through summer and make a good cut flower. Another common name for this plant is Romero or California Rosemary which dates back to the Portola expedition in 1769.

If you want to make a big splash in your garden or container try growing Salvia ’Amistad’ or Friendship Sage. With fast growth in the warm months to 4 or 5 feet tall, the rich royal purple flowers attract hummingbirds and butterflies to the garden. It will grow in light shade with medium water requirements and remain evergreen in warmer parts of your garden.

Cousin Itt acacia

Acacia ‘Cousin Itt’ continues to be a favorite for many of us. This lovely small plant with emerald green, feathery foliage that stays small in the garden and has low water needs. Not to be confused with the bully acacia tree seen around here, it’s one of the good guys. Plant in full sun to partial shade.

So if you’re in the mood to add a couple of interesting plants to your garden, take a tip from what landscape designers use or grow in their own gardens.

Creating a ‘Moon Garden’

As the days grow longer I anxiously await those warm summer nights when I can sit outside and enjoy the evening air. As daylight fades it’s the white or silver plants and flowers that come to life. Whether your view is from a window or from your favorite place on the patio be sure you have a “white garden” to light up the garden late into the evening. Sometimes the best color for your garden is white.

Cornus ‘Mountain Moon’

Even on a grey day a white garden looks fresh and inviting. With so many white flowering plants, those with white variegated foliage and silver leaved plants to choose from yours can beckon you throughout the seasons. White feels relaxed and clean and will slow you down after a long day.

The plants that take a starring role springtime in a white garden include some of my favorites. I just need to get them all in the same area of my garden in order for them to do their magic.

striped variegated foliage. Easy to grow and deer resistant they won’t break your water budget either. The bearded flowers are a spectacular shade of lavender blue and this variety of iris is more shade tolerant than most.

If I add a few more white flowering plants to another area I can have two moon gardens. I wish I had room for a sturdy trellis as I’d surely plant an evergreen clematis. Their scent alone would justify the space. Another candidate for a strong support would be a white blooming wisteria like Longissima Alba. Guess I could get a wisteria that’s been trained as a standard or tree. As it stands I’m keeping a star jasmine pruned to a shrub so I’ll have that sweet fragrance starting in late spring.

Leopard Plant

For my shady garden one of the flowering plants that glows in the fading light of the day or the light of a full moon is pieris japonica or Lily of the Valley shrub. The huge clusters of tiny bell-like flowers are spectacular. Along with the huge variegated foliage of ligularia ‘Argentina’ or Leopard Plant both are sure to draw my eye at the end of a long day.

Choisya or Mexican Orange is one of those work horse shrubs that grows fast, has few pests, is deer resistant and the fragrant lowers will scent your garden in the spring and sporadically throughout the whole year. The handsome foliage looks clean and vibrant even in the winter time.

Rhododendron occidentale

In addition to my white flowering dogwood I have long planned to add California native, Western Azalea to my garden. A true native of California it’s found only in our state except for a tiny spot where it extends into southern Oregon. In addition to the Sierra Nevada it grows naturally in our area and then up the coast north of San Francisco. The large floral trusses are breathtaking- sparkling white marked with a bright yellow spot. The fragrance of the flowers is sweet and spicy clove reminiscent of cottage pinks and carnations. Their beauty and fragrance will enhance any garden.

Other native plants with white flowers are Philadelphus lewisii or Wild Mock Orange. Also Carpenteria californica or Bush Anemone is a beautiful plant to include in a white garden as is silver lupine and douglas iris ‘Canyon Snow’ -often described as being one of the most reliable native iris.

Oakleaf hydrangea

Later in the season look to white hydrangeas– mophead, lace cap or oakleaf- to add to your moon garden. Sally Holmes roses, hardy geranium ‘Biokovo’, Even the common Santa Barbara daisy when planted en masse makes quite a statement in the white garden.

Favorite Plants of Landscape Designers

Big surprise. Many of my friends are also landscape designers. We get together to talk plants, garden design challenges and plant problems while enjoying good food along with a little wine thrown in for good measure. Recently we met in Corralitos to exchange favorite go-to plant ideas and tour the truly fabulous garden of our host. Filled with interesting foliage and texture as well as plants that flower over a long season we all came away excited to use them in our next design. Maybe some of these ideas will work in your own garden.

Fremontodendron californicum

Every interesting garden has good bones. A successful one has a focal point, garden rooms with “walls” and a “ceiling”, plants with different textures and foliage color, repetition and unity. My friend’s garden is no exception.

Rivaling for our attention from the breathtaking view of Monterey bay, a fremontodendron, in full bloom, was a real show stopper. This California native shrub requires little irrigation and provided the perfect backdrop to the entry garden.

Loropetalum / Agave ‘Blue Glow’

Other plants that brought this garden to life included a stunning Blue Glow agave paired with the burgundy foliage of loropetalum rubrum. Both have low water needs and aren’t attractive to deer.

Eggs and bacon plant

A small recirculating fountain tucked within a pocket garden provided an inviting lure for songbirds. Surrounded by the unique lotus corniculatus or eggs and bacon plant along with a tropical-looking melianthus major aka honey bush this garden room invited one to stick around for awhile.

We garden designers were impressed with the size and vigor of acacia ‘Cousin Itt’. This lovely small plant with emerald green, feathery foliage stays small in the garden and has low water needs. Not to be confused with the bully acacia tree seen around here, it’s one of the good guys. Plant in full sun to partial shade.

Euphorbia wulfennii

In deer country you can’t go wrong with euphorbia characias wulfenii ‘Bruce’s Dwarf’. It does an excellent job of seeding itself so beware. Grow it where it can self sow and not become a problem child. Very hardy in winter and water sparingly. In spring and summer the flower heads form at the branch tips covering the plant with a chartreuse color.

A French hybrid lilac called Pocahontas scented the air as we exchanged our favorite plants that pull a garden together. The winners included hardy geraniums like Biokovo and Karmina and California native heuchera maxima. Canyon Snow Pacific coast iris also got a lot of votes. Groundcover sedum ‘Angelina’ and lime thyme garnered support also.

Abelia ’Kaleidescope’ and ‘Confetti’ got the nod from several of us. Also high on the list of favorite plants, the variegated gold and green cistus was used by many because of its low, mounding habit that hugs the ground and provides a bright evergreen accent to a sunny garden.

So if you’re in the mood to add a couple of interesting plants to your garden, take a tip from what landscape designers use or grow in their own gardens.

Flowering Trees & Shrubs of Early Spring

Outside my window the Blireiana flowering plum is covered with dark pink, double blossoms. It’s one of my favorite early spring blooming trees with a sweet fragrance strong enough to scent the garden. We look forward to the earliest flowers of the new season knowing that winter will soon be over. Spring officially begins on March 20th.

Old fashioned shrubs like flowering quince and forsythia figure prominently in many old gardens because they are tough plants able to survive neglect and still look beautiful.

Forsythia ‘Kolgold’

The bare stems of forsythia are completely covered with deep golden-yellow flowers in late winter and early spring and become the focal point of the landscape when in full bloom. The showy stems of this easy care shrub are great for cutting. Forsythias are native to eastern Asia but a chance discovery in Germany by a grower who specialized in breeding for the cut flower industry led to the especially vivid variety ‘Kolgold’ in the 1800’s. Forsythia has long been used in Chinese medicine. The flower petals contain powerful bacteria-fighting properties which make it an important dressing.

Flowering quince

Flowering quince is another old garden staple providing early color. They are easy to care for and nearly indestructible in almost any soil that is well drained and not overly fertile. Once established quince is a very drought tolerant plant and their spiny branches make them an excellent choice for hedges, screening or as a security barrier. There are red, pink, orange and white flowering varieties. The Toyo Nishiki cultivar even has pink, white and solid red flowers all on the same branch.

Clivia miniata

What would a shade garden be without a bright orange clivia? Every year I look forward to their huge flower clusters that emerge from between dark green, strappy leaves. Even in dark shade they will bloom and brighten the winter garden although they would do fine in morning sun. If you have a north facing window you can grow them as houseplants. Clivia are hardy to several degrees below freezing but mine, under an overhang, have survived temps of 23 degrees without damage. Clivia breeders have produced gold and peach colored flowers also but I still like the standard orange ones.

A beautiful vine that blooms in winter is hardenbergia ‘Happy

Hardenbergia ‘Happy Wanderer’

Wanderer’. In the pea family, this evergreen vine looks like a small wisteria when in bloom. Pinkish-purple flowers cascade in clusters on twining stems that reach 12-16 feet long. It requires little water once established and is hardy to about 23 degrees. If you have an older, tangled plant you can rejuvenate it with hard pruning in early spring after flowering. Never prune in late summer or fall because you will cut off the wood that is going to bloom the following winter.

The last plant I couldn’t live without is Fragrant Sarcococca. The tiny white flowers of this plant are easily overlooked but you can’t miss their scent. I have one near the front door that greets me with that vanilla fragrance every time I walk in or out. The flowers are followed by a bright red fruit. Sweet Box forms a natural espalier against a wall and if you have a problem spot in deep dry shade where other plants won’t grow give this plant a try. They are easy to grow, deer resistant and trouble free.

Garden Tasks-Rain or Shine

Those of you who lived in the Santa Cruz mountains during the winter of 1982 remember it well. Following two days or torrential rains, a large section of hillside above Love Creek gave way. Thirty homes were destroyed and ten people were killed by the slide. The rainfall totaled 111 inches that year.

During the winter of 1997 the San Lorenzo Water Department recorded 90 inches of rain. The department’s historical rainfall data goes back to 1888 and shows that during the winter of 1889 a whopping 124 inches of rain fell. This winter is one to rival the books with about 70-110 inches of rain falling so far depending where you live. We don’t aspire to break any records.

How does this much rainfall affect our gardens? If you have addressed drainage issues and are slowing, spreading and sinking all this water, congratulations. But what about the plants? Fortunately most plants are dormant or semi-dormant at this time of year. Even plants that don’t lose their leaves aren’t in growth mode yet. When a plant is actively growing either roots or new foliage it will suffer if the roots are soggy day after day. Fungal problems and root rot will take its toll on a plant. An extremely wet March or April is not a good thing.

We gardeners are the eternal optimists and hope that only gentle rains will fall through May. And during those lulls in the weather this is what I’m going to be doing over the next month.

California fuchsia – zauchneria californica

Prune fruit, nut, shade trees and deciduous vines like clematis. Cut back woody shrubs like Mexican bush sage, artemisia and butterfly bush to stimulate lush new growth. You can cut back these plants close to the ground. Don’t use this approach on lavender or ceanothus, though. Prune them lightly after blooming without cutting into bare wood.

Prune fuchsias back by a third and remove dead, crossing branches and interior twiggy growth. Container fuchsias can be cut back to the pot rim.

mophead hydrangeas in June

Cut back hydrangeas stems that bloomed last year and apply a soil acidifier if you want the flowers blue. Although sulfur is the traditional favorite for quickly acidifying soil it is not as kind to many beneficial soil microorganisms. Coffee grounds, pine needles, peat moss and cottonseed meal are better for your soil.

I’ll wait to prune back perennials that may have their new foliage damaged in a late frost. Already damaged foliage can protect a plant from further frost damage. Mid-March is the estimated date of last hard frost in our area. Or at least it used to be.

Don’t cut back grasses yet if you get frost in the area where they grow. Wait until mid-March. If you live where you rarely get frost go ahead and prune these plants back now. I’m going ahead and pruning California fuchsia, salvia ‘Bee’s Bliss’ and hummingbird sage now. They look terrible.

camellia sasanqua

Don’t prune spring flowering shrubs and trees like lilacs, flowering cherries, plums and crabapples, rhododendrons, azaleas, camellias, weigela or spirea until after they flower. You can cut some branches during flowering to bring in cuttings for bouquets.

I can tell that spring will soon be here as the flowering plum buds are showing color. Can’t tell from the weather report, though.

About Roses

Roses are the flower of love. Many of us have fond memories of favorites in our mother’s garden or of a beautiful bouquet given or received on Valentine’s Day. It’s dormant season for roses which is good for both pruning and adding a few to the garden.

David Austin rose

As a designer I have clients who have inherited roses and want to keep them as a remembrance. Others want to create a cutting garden filled with roses and other perennials. Don’t feel guilty for growing those beauties in your own garden. They use less resources than you think and there are many ways to grow them sustainably.

Roses, whether bush types, climber or ground cover carpet varieties, use a moderate amount of water in order to thrive according to the latest Water Use Classification of Landscape Species (WUCOLS) list. This amount of summer irrigation is the same as many of the plants on the list of Scotts Valley Water District’s 800 Approved Low Water-Use Plants for lawn replacement. Plants such as Emerald Carpet manzanita, Joyce Coulter ceanothus, Siskiyou Blue fescue grass, Pacific wax myrtle, butterfly bush, yarrow hybrids and Tapien verbena have similar water requirements.

Since now is the time to prune your roses here are a few tips.

Strike it Rich hybrid tea rose

Prune shrubs moderately to keep them compact. The goal is to keep the center of the plant open for good air circulation aiming for a vase-shaped bush with an open center. Cut out canes that cross, appear weak or are diseased, spindly or dead. Healthy canes appear green or reddish while old and dying canes are brown. Cut back the remaining stems by about one third. When pruning, cut canes at a 45-degree angle just above an outward facing leaf bud or a swelling on the cane. Clean pruners after every use to prevent the spread of disease and keep your pruners sharp.

Prune heirlooms roses such as David Austin and other old antique garden roses less because their open look is part of their charm.

Same goes for climbing roses. Cut out extra stems if there are too many and also cut back long established canes to about the place where they are slightly thicker than a pencil. Then cut each side stem down to several inches. This will make the cane flower along its complete length for a beautiful spring display.

Zepherine Drouhin climbing rose

Pluck off and rake away any old leaves. They can spread fungal spores. Consider spraying dormant plants with a combination of organic horticultural oil and copper soap or lime-sulfur. If you usually only have problems with black spot you can use a mixture of 1 teaspoon baking soda with a few drops of light horticultural oil in 1 quart water and spray every 7 to 10 days during the spring.

Prune your roses throughout the growing season, too. Deadheading, or cutting off spent flowers, encourages plants to re-bloom. Mulch around your roses to conserve water and encourage soil microorganisms.

Don’t worry whether you’re pruning job is perfect. Roses are super forgiving and you can always trim them up again later.
