What Landscape Designers Grow in their own Gardens

alstroemeria_Inca-Ice.1600It probably won’t come as a big surprise to you that I have a lot of friends that 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 I had the opportunity to visit one of these friends and although I was only there briefly to pick up something I couldn’t help but ask about several of the beautiful plantain her own garden. Some of her favorites include those with interesting foliage and texture and that flower over a long season. Maybe some of these plant ideas will work in your own garden.

Being winter and all I was immediately drawn to the hundreds of soft apricot and creamy yellow flowers covering a 3 foot wide Peruvian Lily. This selection of alstroemeria, called Inca Ice, is much shorter and compact that the taller ones that can be somewhat floppy in the garden. Alstroemeria were named by Carl Linnaeus, often called the Father of Taxonomy, for his friend and student Klaus von Alstroemer. Native to South America, the summer growing types come from eastern Brazil while the winter growing plants are from central Chile.

Peruvian Lily spread slowly outward from rhizomes and grow in full to part sun. They are hardy to 15-20 degrees and can tolerate dry conditions although they look best with irrigation. The Inca series grows 2-3 ft tall and can be covered with flowers from spring to late fall or winter if the weather is mild. The flower stems are long enough for cutting. This variety also comes in light orchid, pale yellow and white with red and green markings. What’s not to love about this plant?

Tucked next to the blooming Inca Ice Peruvian Lily, a clump of bright, Festival_grass-leucodendron.1600burgundy red Festival grass complemented the soft yellow of a Leucodendron discolor and a variegated Flamingo Glow Beschorneria. I was not familiar with this variegated agave relative with its soft-tipped chartreuse striped leaves. I found out this beautiful plant is drought tolerant, hardy to 15 degrees and will bloom with 5 foot pink stalks with reddish pink bracts.

Other plants that boast more foliage color than flowers brought this winter garden to life. Several varieties of helleborus just starting to show pink, white and rose color were surrounded by the brilliant chartreuse-yellow foliage of sedum Angelina ground cover. A variegated Japanese Lily-of-the-Valley shrub grew nearby getting ready to bloom soon.

Beautiful bright pink, cream and green variegated Jester Leucodendron bordered the driveway. I’ve seen this plant also called Safari Sunshine in nurseries. With its smaller size of 4-5 feet this evergreen shrub has showy, rich red bracts that sit atop the branches now in late winter and lasting into spring. Drought tolerant like Safari Sunset and deer resistant, too, leaucodendron are hardier than other protea.

Every interesting garden has good bones. It has focal points, texture, repetition and unity among other elements. My friends garden is no exception. A lovely caramel colored New Zealand Wind Grass dominated another area allowing my eye to rest for a while. I wish they would quit renaming this plant that used to be stipa arundinacea but is now anemanthele lessoniana. The name doesn’t exactly roll off the tongue but the effect is beautiful in the garden. I’ve always called it Pheasant Tail grass but I could find no reference as to why this common name is used. Life used to be simple before DNA sequencing!

So if you’re in the mood to add a couple of interesting plants to your garden, take a tip from what a landscape designer grows in her own garden.

Treats & Tips for the September Garden

salvia_m_Hot-LipsYou can feel the weather changing as summer winds down. It’s more than just the passing of the Labor Day holiday and the school year starting. The nights are longer and cooler. The days are not quite so hot and the flowers in the garden seem brighter and more colorful. I look past the soft blue and lavender blossoms and am drawn to the warm shades of gold, rust, orange, hot pink and red. They shout autumn is on the way.

There’s nothing quite like adding a few new perennials to brighten up the garden. There are many that don’t require a lot of water after they become established. I recently visited a garden where the irrigation was reduced to the point that that most of the plants were barely hanging on. But there among the crispy plants were two Hot Lips salvia blooming as big as you please. This plant is popular for a reason. Hummingbirds, butterflies and bees love it and it blooms for a long time. It stays compact and is a great carefree shrub for water wise gardens.

Daisy flowers always bring a smile to my face. As members of the composite family they have echinacea_Wild_Berrya flat landing surface for butterflies to land on. Coneflowers are one of my favorites. When they start blooming in the early summer I enjoy them both in the garden and as cut flowers inside. Some have a slight fragrance. Hybridizers have introduced beautiful shades of gold, yellow, orange, burgundy and coral in addition to the traditional purple and pure white. Because they are dormant in the winter they are good candidates for the garden that has summer sun but winter shade. They are not attractive to deer and are good additions to the low water garden.

gaillardiaAnother perennial that blooms throughout summer and fall is gaillardia also known as blanket flower. I’ve seen this tough plant grow in neglected gardens that the owner swears does nothing to keep it going. They are covered with dozens of large reddish-orange flowers with yellow edging and bloom over a long period. This plant also attracts butterflies. You can start perennials from seed at this time of year for next year’s bloom.

Don’t overlook the color of other foliage plants like Orange Libertia, Abelia ‘Kaleidescope’, New Zealand flax, red fountain grass and Japanese bloodgrass in the garden.

Now through October, divide summer blooming perennials like agapanthus, coreopsis, daylily and penstemon that are overgrown and not flowering well. You can also divide spring blooming perennials like candytuft, columbine, astilbe, bergenia and bleeding heart but sometimes they don’t bloom the first spring afterwards due to the energy they use re-establishing themselves.

Another thing to do while out in the garden this month is to cut back berries vines that have produced fruit. Canes of the current season should be trained in their place.

Spider mites are especially prolific during hot, dry weather. Sometimes you don’t even know how bad the infestation is until all your leaves are pale with stippling. Periodically rinse dust and dirt off leaves with water. Spray the undersides of infected leaves with organics like insecticidal soap switching to neem oil if they build up a resistance to one of the pesticides.

Soon it will be time to start cool season veggies or plant cover crops in the garden. It’s never too soon to start planning for erosion control in those areas that caused you problems during last spring’s storms. But for now add some early fall color and have fun in the garden.

How to Design a Perennial Border

rhododendron_occidentale2.1600When I visit my best friend’s house I park next to the perennial border that lines her driveway. At any given time of year there is something blooming, flowers filling the air with fragrance and juicy apples hanging on the tree for picking later in the summertime. She has some California natives as well as traditional cottage garden plants all mixed in together. Originally from Illinois, she loves a garden filled with lush green and color but has designed the space with plants that can use less water than you would expect and still look spectacular.

What makes for a successful border? You see DIY articles in the gardening magazines showing lovely combinations with rules to follow but they always seem to be for a different climate or location. We often have borrowed scenery from the mixed woods and some of their ideas just don’t work well here. Here are some tips for planting a terrific perennial border in our neck of the woods.

Some of the key players in my friends perennial border are natives like Western azalea, kerria_japonica2hazelnut and flowering currant. These are large, woody shrubs that add height, texture and year round interest. They provide the backbone or structure to the border throughout the seasons and even in the winter. She also has a weeping bottlebrush which is evergreen and provides nectar for the hummingbirds as does the flowering currant. An apple tree and a persimmon tower over all the other plants creating a canopy for the shrubs, herbaceous perennials and groundcovers. You could also plant spirea, weigela, cornus and viburnums to provide structure to your border.

My friend’s border is planted so that there is something of interest every month during the growing season. The persimmon tree is the star of the late fall garden with bright orange fruit that hang like ornaments on the tree. In the spring I can’t take my eyes off the kerria japonica whose graceful shape is covered with double golden, pom pom shaped flowers. The vivid, new foliage of the Rose Glow barberry complements the stand of Pacific coast iris with similar cream and burgundy flowers blooming next to it.  Under the bottlebrush a sweep of billbergia nutans or Queen’s Tears is flowering with those exotic looking, drooping flower clusters. They make a great groundcover under the tree and also are long lasting in a vase.

ompholodes2.1600Mid-sized filler plants that thrive in this border include Hot Lips salvia, daylilies and polemonium to name just a few. Daffodils and tulips have naturalized throughout the space. Groundcovers grow thickly to shade the soil and prevent precious moisture evaporation.  Lamb’s ears like their spot under the flowering currant and the omphalodes have spread throughout the border. This little plant looks and blooms like the forget-me-not but the delicate deep blue flowers don’t produce those sticky seeds that plague both our socks and animal fur.

This border get morning sun and mid-afternoon sun until about 3pm. If you have a situation that calls for all sun lovers you could try asters, shasta daisy, grasses, coreopsis, achillea, echinacea, gaillardia, sedum, kniphofia, lavender, liatris and rudbeckia.  Perennials that work well to attract butterflies and hummingbirds include monarda and my personal favorite, cardinal flower.  Both have long, tubular flowers in bright colors such as red, orange and yellow. it’s easy to have the birds and butterflies coming all season when you plant perennials with overlapping bloom times.

Perhaps some of these plant combinations would look great in your garden, too. Just don’t worry too much about the “rules” of perennial borders. Mix it up. You don’t want the border to look like stadium seating. The idea is to have fun and create a border that makes you happy.

The Sloughs of Watsonville

sambucus_nigra_berriesEach year I wait for them in my garden and so do the robins, varied thrush, jays, spotted towhees, grosbeaks and band-tailed pigeons. The fruit of sambucus mexicana, a California native plant, is relished by an incredible number of songbirds.  The creamy flower clusters in the spring are a favorite of bees and other beneficial insects. My Western Elderberry grows tall and gangly in the shade of a California bay tree, shorter and more compact in the sun. Their exuberance for life makes me happy just to watch them provide for so many other species.

We've all driven down Hwy 1 past the strawberry fields and seen the wetlands at high tide as their many fingers reach far up into the Watsonville area. At low tide the Harkins Slough is visible off to the west, grasses blowing gently in the wind. Struve Slough passes under Hwy 1 also but most of it is hidden. The Watsonville sloughs wind around farms, fields and low hills not visible from the highway.

California has lost over 90 percent of its wetlands and the Watsonville Sloughs are one of the largest remaining freshwater marshlands in the state's coastal zone. It provides a crucial resting place for many specie of migrating birds. This area covers about 800 acres adjacent to the city of Watsonville. The slough system has 6 interlinked freshwater sloughs fed by the waters of the Pajaro Valley watershed.

Many of the plants native to the wetlands will be available at a sale to fund educational programs put on by the organization Watsonville Wetlands Watch who's mission is to protect and restore the wetlands while educating the community.

The Native Plant and Backyard Festival will take place Saturday, September 28th from 10-2pm at the Fitzeriogonum_rubescens Wetlands Educational Resource Center building behind Pajaro Valley High School. It will be their second annual plant sale. Plants beneficial for backyard habitat gardens will be featured many which were grown in their own greenhouses. Natives like buckwheat or eriogonum as they are called are a mainstay of the slough ecosystem as well as our chaparral areas and several varieties will be offered for sale.

One of my favorite eriogonums is the Red Buckwheat for several reasons. In addition to attracting beneficial insects the flowers can be dried and used in arrangements. The roots are deep and will hold the soil and bring up subsoil nutrients to the surface. They are very drought tolerant. In the weeks to come the buckwheat's long nodding flower heads will produce a huge bounty of seed favored by migrating songbirds and water birds, some of which will spend the winter here.

Coast asters will also be available for sale and make a nice addition to any garden. They provide flower color in the fall and combine well with other perennials and grasses such as yarrow and Idaho fescue. They colonize easily and help stabilize slopes and banks and can also be used as an understory plant. They are very drought aster_chilensis2tolerant. Native grasses will also be for sale as well as plants of the coastal prairie and wildflowers.

Besides the native plant sale,  Watsonville Wetlands Watch will have workshops with expert speakers, an Eco Kid Zone, food, a marimba band, a raffle, live animals and local wildlife displays. Free habitat consultations for your own backyard, demonstration habitats, a wetlands wildlife photography exhibit and a tour or their new greenhouse.

For more information about the sale and this wonderful organization visit www.watsonvillewetlandswatch.org

Your own backyard can make a difference for wildlife. Even a small plot of plants rich in nectar and pollen along with some water, rocks, stones and mulch can make your backyard come alive. Create your own backyard habitat by choosing the right native plants to attract butterflies, birds and other fauna and at the same time conserve water and help maintain the diversity of our animal population.
 

Chocolate in the Garden

Chocolate_Flower_Farm_perennial_beds 2Gardeners are always on the look out for new plants. I recall when I worked at a nursery looking over the showy dahlia shipment for the one that was a deeper, more vivid shade than all the rest. One color that always gets my attention is chocolate.  Whether I find it in the foliage of a plant or the flower itself it's one of my favorites. You can imagine my delight when I discovered the Chocolate Flower Farm in Langley on Whidbey Island while I was visiting the Puget Sound recently. I was a kid in the candy store.

As a landscape designer I often get requests for certain colors to be included in the plant palette. Mahogany,burgundy, deep magenta, midnight blue, eggplant often make the list. Many people like dark flowers or foliage paired with ivory, others prefer peach or chartreuse. I marveled at all the combinations at the Chocolate Flower Farm.

Some plants are the color of chocolate and some smell like the real thing. Chocolate cosmos looks and smells chocolate_colored_flowers 2just like a dark chocolate bar. The warmth of the day releases this delicious fragrance. A favorite flower for the perennial bed it's always a winner with kids.

In addition to chocolate cosmos, a wildflower called chocolate flower or berlandiera lyrata grew at the farm. I also enjoyed the fragrance of warm chocolate in the flowers of chocolate akebia, chocolate mint and chocolate snakeroot.

Strolling the grassy paths at the Chocolate Flower Farm  I admired a Sparkling Burgundy pineapple lily. The foliage, nearly black, glistened in the sun growing next to a white-flowering Nine Bark called Summer Wine.
Nearby a clump of two-tone chocolate and ivory daylillies bloomed. With grazing horses nearby and a dozen ducks taking turns bathing in a kiddie pool the scene was idyllic. At every turn a different pairing of chocolate flowers and foliage caught my attention.

One section featured plants for a kid's chocolate garden. Easy to grow chocolate pincushion flower, chocolate viola, chocolate nasturtium, chocolate snapdragon, chocolate sunflower and chocolate painted tongue would be fun for any child to have in their own garden.  

I loved a penstemon called Chocolate Drop as well as a Mahogany monarda the color of deepest magenta. Blooming black sweet peas grew up and and over an old bed frame. A dark purple-black clematis from Russia called Negritanka intertwined with lime green hops covering an arbor. Toffee Twist sedge, Royal Purple smokebush, Chocolate Sundae dahlia, Sweet Hot Chocolate daylily, Chocolate Plant and Hot Cocoa roses grew in many of the flower beds.

Himalayan_pheasant_berry 2What makes dark foliage or dark flowers pop?  At The Chocolate Farm each bed pairs the deep rich chocolate color with another contrasting shade. I don't know which was my favorite. One area featured peach, pink and silver to offset the darker shades. Pink dahlia and fairy wand, blue oat grass and rose colored sedum 'Autumn Joy' made a lovely vignette. Another bed paired the yellow flowers of phygelius 'Moonraker' and digitalis grandiflora with white anemone and ivory dahlias set among Chocolate Baby New Zealand flax.

Not to be ignored the dark chocolate shade of black sambucus growing next to a golden Himalayan Pheasant Berry made an impression. All-gold Japanese Forest grass at the base of dark leaved Tropicana canna lily was also a show stopper.

If you are up on Whidbey Island, the Chocolate Flower Farm is a great place to spend an afternoon. If your vacation plans don't include the Pacific Northwest, plant some chocolate in your own garden.

 

A 100 Year Old Garden near Quail Hollow

lawn_perennial-bordersVisiting gardens is one of my passions. Wherever I travel I take time to enjoy an arboretum or a historical garden wherever I find them. Local gardens can be just as exciting and recently I was invited to stroll and marvel under majestic oaks in a beautiful garden near Quail Hollow.

This 25 acre property was first developed by an Englishman in the very early 1900's. After building an Italian Mediterranean style house featuring plenty of earthy materials such as terra-cotta paver floors and patios, red clay tile roof, stucco walls, rustic wood beams and enclosed outdoor spaces, he set out to landscape the property.

A spring fed creek provides water to a woodland garden with 40 foot rhododendrons still thriving and in full  bloom during my visit. Western azaleas scented the air and the horsetail, columbine and white calla lily rhodie_bicolor2grew lush in the moist soil. The original owner built Japanese inspired stone bridges over the creek, the remnants still poking through the ferns.

Huge stands of black bamboo and golden bamboo border the creek in another area making me wonder if perhaps he became interested in these exotic plants after the 1915 San Francisco Panama-Pacific Exposition that showcased plants from all over the world. The current owners have installed a 3 foot barrier to keep the bamboo in check. Now towering 25 feet tall, the black bamboo shades the house on the south side with stems 2" thick.

The property passed from the original owner to a concert pianist who lived there until she died. The current owner bought the property in an estate sale in the early 1970's. When he married Nancy 23 years ago the garden again came to life. The front yard which had been a flood-irrigated horse pasture was transformed into the magical place it is now.

Nancy is the perfect steward of the land. Interested in all growing things she has surrounded the lawns with shrubs, perennials, grasses and flowers of every type. Sunny borders bloom with trellised Cecile Brunner roses, pink clematis montana and purple Jackmanii clematis along with lots of bright red climbing roses. By providing support, Nancy has even coaxed Apple Blossom and other carpet roses to bloom off the garden floor.

In addition to her gardening successes, Nancy shared her ongoing nemesis. Every year she said she hand picks at least a hundred white gaura that have self-sown. Seems Siskiyou pink is not as prolific. The crocosmia Lucifer have overtaken one bed and she begged me to take some. I politely declined. Her white Japanese anemocourtyard2ne threaten to march into the lawn but the pink variety is better behaved. Nancy takes it all in stride. You can feel her love of gardening and plants at every turn.

Nancy loves perennials. The chocolate cosmos were just emerging but the double coreopsis, Spanish and English lavender, Moonshine yarrow, Japanese iris, douglas iris and columbine were in full bloom. In a shady spot by the old icehouse daphne, azalea and pieris had just finished their show. The hydrangeas were all budded and ready to take over the spotlight.

We walked through a lovely enclosed courtyard complete with formal fountain and Nancy pointed out containers of gardenias, Evergold carex grass, a deep red Bob Hope camellia and huge woodwardia ferns. She planted the rhododendrons bordering the courtyard over 20 years ago. A gopher did get 3 of the camellias last year but she's now replanted in gopher baskets. Her Japanese maples, started from seedlings, are now 6 ft tall with trunks over an inch thick.

I'll never forget the afternoon Nancy shared her garden with me and Sherman, the springer spaniel I was dog-sitting.  It's an enchanting place and I'm looking forward to visiting again.
