Pacific Dogwood & Plants with Seasonal Interest

Driving east to Yosemite recently, I was reminded of how diverse botanically and geologically is the state of California.  Leaving the redwood forest here, I passed tawny grasslands and oak studded foothills to a mixed evergreen forest up in the Sierras. Many of the same plants grow here- buckeye, solomon seal and western azalea. I was hoping the native Pacific dogwood would still be blooming and was not disappointed. Huge white flowers, resembling butterflies, covered these small trees. I last saw them a couple of years ago when they wore bright red fall foliage. This got me thinking. What other plant are interesting in more than one season?

Other plants that make a bold statement in the garden are big-leaved perennials. If one of your garden beds or borders need something to quickly enliven the scene, look to giant leaves to give contrast. Often a planting will have too many similar flower or leaf sizes and end up looking fussy, overly detailed and chaotic. That’s when large architectural plants come to the rescue.

Ligularia dentata form 3 ft. clumps in partial shade. From midsummer to early fall, 3-5 ft. stems bear 4" wide orange-yellow daisy-like flowers. Their leaves are the most striking feature. Othello has deep purplish green, kidney-shaped leaves almost a foot across while Desdemona has leaves with purple undersides and green upper surfaces. Ligularia clumps can remain undisturbed for years and stay lush and full from springtime through frost.

For borders in the sun, cannas add drama. They stand bright and tall with huge leaves on 4-6 ft. stems. Some like Pretoria and Tropicana have striped leaves and others have bronze leaves like Wyoming and Sunburst Pink. Flowers range from orange, red, pink, yellow, cream and bicolor. Canna leaves are useful in flower arrangements but the flowers themselves do not keep well. In the garden border, canna foliage, backlit by sunshine, positively glows.

Red bananas are grown for the impact of their beautiful leaves which range in color from deep claret brown to re-purple to green. Plant them in full to part sun in an area protected from the wind to avoid shredded leaves. Ornamental bananas grow fast to 15-20 ft and make a bold tropical accent in any garden.

 

Pruning Japanese Maples

MId-June and everything in the garden is full and lush. Your Japanese maples might be getting a little too full for your taste-outgrowing its space, crowding the neighbors, looking like a boring blob. Take the fear out of pruning with these easy steps.

Pruning any plant is necessary for several reasons-to control size or shape, to remove dead or diseased branches, to improve structure or to stimulate new growth. Pruning also can improve the health of a plant by increasing air circulation, allowing more light into the center and reducing disease problems.

Japanese maples do not need a lot of pruning. June is the best time of year to prune them as the leaves have become full size. The least favorable time to prune would be early to mid fall just as it is sending nutrients and energy to store for the cold months. Bring out your tree’s personality by symmetrically thinning out about a third of the small twigs throughout  the tree and any dead twigs. Japanese maples less than 15 years old are prone to put on new growth that looks like a buggy whip: unattractively skinny with no side branches. Shortening or removing the buggy whips only stimulates more of the same. Be patient. You will be surprised to find that, as the whips age, they fatten up, develop lateral branches, and turn into nice-looking scaffold limbs. Make sure not to thin to much on the sides of the tree if they are exposed to sunlight as that could cause sunburn. Use the "1/3 rule" when deciding where or how far back to cut a branch – that is prune to an upward or outward growing branch that is at least a third as big as the one you are cutting.

Avoid attempting to restrict the height of a Japanese maple. It won’t work. The tree will simply grow faster with thin, unruly branches. You can reduce the height of the tree a bit by removing branches that grow in an upward direction to a lower branch. The width of these trees, on the other hand, can be somewhat modified. Trim side growth and foliage that is hanging too low by cutting to branches farther back in the tree. It’s time consuming to prune a little, then stand back to decide where the next cut will be, but when you’re finished, your new tree will have an airy, delicate appearance allowing you to see into the tree and admire the

 

Landscaping Tips for Great Gardens

By this time of the year, you probably have planted some new perennials for color in your garden. But if you look around and still feel something is missing the answer may be that your landscape needs more than color. As a landscape designer I am often called upon for ideas to create richer landscapes that provide four seasons of interest. Here are some tips I pass along.

A more sophisticated appeal and enduring quality in your landscape can be achieved if foliage color is used to complement, or contrast with, other plants within the design. This technique unifies the overall look while offering appeal throughout the season. One plant that would make this happen is Rose Glow Japanese barberry. Their graceful habit with slender, arching branches makes a statement by itself but it’s the vivid marbled red and pinkish foliage that steals the show until they deepen to rose and bronze with age. In the fall, the foliage turns yellow-orange before dropping and bead-like bright red berries stud the branches fall through winter.

Abelia Confetti is another small shrub that can be used to unify your landscape. Growing only 2-3 ft high and 4-5 ft wide with leaves variegated white, their foliage turning maroon in cold weather. Abelias are adaptable plants, useful in shrub borders, near the house or as as groundcover on banks. White, bell-shaped flowers are plentiful and showy during summer and early fall.

Texture in foliage is very important in good garden design. Varying the size and shape of leaves creates diversity and variety among neighboring plants. Striking visual interest can even be achieved when working with two different plants with similar shades of green.

An example of this would be combining Gold Star pittosporum tenuifolium with grevillea noellii. The first has dark green oval foliage on 10-15 for dense plants while the latter is densely clad with narrow inch long glossy green leaves. Clusters of pink and white flowers bloom in early to late spring and are  a favorite of hummingbirds.

Using the same plant shape throughout a landscape can create and tie the entire design together. Forms and shapes of plants and trees can be columnar, conical, oval, round, pyramidal, weeping, spreading and arching. A loropetalum with its spreading tiers of arching branches could be repeated throughout your garden to create visual interest and balance. A dogwood tree could also repeat this same form as their branches grow horizontally.

Consider also layering plants to create a beautiful garden. From groundcovers all the way up to the tallest tree, natural looking designs mimic nature.

Don’t forget about focal points. This could be a Japanese maple cloaked by a wall of dark evergreens or a statue or pottery at the end of a long, narrow pathway. Focal points draw attention and even distract the eye from an unsightly view.

There are many solutions to make your garden complete. Consider using some of the above design elements to make your landscape beautiful. 

Unthirsty Plants

Our summer unofficially kicked off with Memorial Day weekend. What better way to start the season than to spend some time outdoors and do a little gardening?

Plant some new water efficient plants for color and to attract hummingbirds and butterflies. Afterwards spread  fresh bark or compost to mulch the soil. This insulates and protects shallow roots from the heat of the summer sun. While keeping the soil cool, mulch slows the evaporations of water from the soil so it stays moist.

Some of my favorite plants are survivors– easy to grow with minimal water use once established while also attracting hummingbirds and butterflies to the garden.

Ceanothus is one plant that does it all.  Brilliant blue or stark white flowers in spring provide nectar for both hummers and butterflies.  Ceanothus also provide food for butterfly larvae. A new ground cover variety with gold and deep green variegated foliage can bring color to the garden year round. Growing 3-5 feet wide and 2 feet tall this perennial can survive with only occasional summer water.

Everyone should have some lavender in their garden. Hummingbirds and butterflies both favor this plant and there are new introductions every year from growers. Elegance Purple forms a bushy compact mound with sensational purple flowers in early sumer. Goodwin Creek is an old stand-by that blooms from spring to late fall with deep violet blue flowers. For midsummer bloom plant Grosso which is a widely planted commercial variety in France and Italy. It’s possibly the most fragrant lavandin or all. Spanish lavender blooms spring into summer if sheared. By planting an assortment of lavenders you can have a succession of flowers throughout the season.

Penstemon also lure hummingbirds and butterflies to the garden. They come in a wide range of colors and varieties from native species to garden hybrids. Another long blooming, tough plant is achillea Moonshine (yarrow). Butterflies love to alight on their yellow flat landing pads. The dense flower clusters make good cut flowers and the gray-green foliage blends with all color in the garden. Yarrow need only routine care once established. They can take some watering although they endure drought once established. Cut them back after bloom and divide when clumps get crowded. 

There are so many salvias to choose from and all are great additions to a tough love garden. Autumn sage blooms summer through fall in colors ranging from deep purple through true red to rose, pink and white. Purple Pastel is especially beautiful covering 3-4 foot plants with blossoms filled with nectar for hummingbirds and butterflies.

Those who seek true blue flowers for their gardens might try planting salvia chamaedryoides. This elegant front-of-the-border plant has silvery foliage which sets off the brilliant blue flowers. Heaviest bloom is in late spring and fall. Deadheading encourages rebloom.  This salvia is drought tolerant but blooms longer and better with a little summer water.

Three more un-thirsty bloomers that even beginner gardens can’t kill are . All attract hummingbirds.  Coreopsis also make good cut flowers.
 

A White Garden with Fragrance

Gardens are living things-changing over time. One year everything in the garden seems to bloom in April and May. Other years different plants reach maturity and provide color and structure during the summer. If your garden needs a few plants that will "pop" in the landscpe why not add a white bloomer that you can still enjoy after the sun goes down?

A great looking native plant for the back of the border is philadelphus lewisii or wild mock orange. Fragrant, white, satiny 2" flowers attract butterflies in late spring and early summer. Goose Creek is a doulbe-flowered selection that forms a fountain shape 4-10 ft tall and is fairly drought tolerant. Not fussy about soil type but it must have good drainage.

Another sweet-scented, white flowering Ca. native is carpenteria californica or bush anemone. Although this plant needs little water once established it can also accept ordinary garden conditions making it valuable closer to the house in the "lean, mean and green" zone that the fire dept wants irrigated more to retard flames. Clusters of fragrant 2-3" white blossoms with yellow centers appear at the ends of the branches. This shrub grows slowly to 4-6 ft tall and would be beautiful along a path or next to the patio where you could enjoy it’s fragrance in the evening, too.

Roses are among the showiest fragrant flowers you can grow in your garden. Sure they need a little extra water but the pay back is spectacular. Place them in areas with other plants that need regular water. Here are my favorite white roses.

Full Sail- a medium upright hybrid tea rose with large bright white flowers and a strong honeysuckle fragrance.
John F. Kennedy- Huge, full greenish white buds open to rich white and smell like licorice. This rose stands up well to hot weather.
Iceberg- One of the top ten roses of the workls and the best landscpe white around. It also comes as a climber. Honey scented rose clusters are borne in great profusion. This rose is extremely disease resistant and needs little care.  Looks great as a hedge or in mass plantings. This the the part I love, they have very few thorns.
Stainless Steel-  A rose that is so close to white it would shine in a moon garden. With pale silvery lavender flowers and a fragrance stronger than Sterling Silver it’s easier to care for and grow. Flower size and color are best with cooler temperatures or in a bit of shade.

What else can you grow in a white garden? If I had more room, I’d have a Longissims Alba wisteria with pure white fragrant flowers that cascade in spikes up to 4 ft long. Or I’d grow a Krasavitsa Moskvy lilac whose lavender-rose tinted buds open to full, double, creamy, fragrant white flowers.

I also like the also called mock orange because it’s flowers really do smell like citrus blossoms. Their green and white foliage can lighten up a dark corner in any garden and scent the air. Tuck some sweet alyssum along a path and your white garden is complete.

Permaculture and You

We all want to do the right thing for the environment by reducing our carbon footprint and becoming good stewards of the land. We want to build our landscapes with green products and incorporate sustainable practices in the garden. A good way to do this is to create gardens that offer food and beauty for people while providing habitat and other benefits for the rest of nature.

Permaculture is the fancy name for this approach to garden design. When you garden using organic fertilizers and organic pesticides ( when necessary ) you reduce pollution in the environment. When you plant edibles like beautiful fruits, vegetables and herbs in your yard, you create a more natural landscape that takes better care of itself while yielding a plentiful harvest of plants for food.

You can put these ideas to work in your own garden by using water more efficiently and carefully selecting and siting plants. Deep rooted trees like fig, mulberry, peach and plum help break up heavy soil and shade the plants beneath them. Planting drought tolerant trees creates shade which in turn slows the evaporation of moisture from soil and prevents erosion.

Group plants with similar water needs. Grow thirsty plants in the lowest areas of your garden where more water collects. You might install a rain garden in an areas like this. A rain garden is simply a planted depression designed to absorb run-off from areas like driveways, walkways, roofs and compacted lawn ares. The rain garden acts to replenish ground beds while preventing water from running into storm sewers, streams and creeks.

Plant dry climate plants like lavender, rosemary and sage in open, sunny areas and drought tolerant ground covers like oregano and thyme to shade the soil and conserve moisture. Use less turf grass and more walkable ground covers where possible.

Place hardy perennials like artichoke, butterfly bush and rhubarb under tree canopies to conserve moisture. In general, use deep-rooted, low maintenance perennials that provide food and also shade for plants underneath.

For food, plant fruit trees, berries, nuts, herbs and vegetables. To create habitat, plant fennel, spearmint and yarrow for beneficial insects; butterfly bush and sage for pollinators such as bees and hummingbirds; ceanothus and other native shrubs and trees for birds and other wildlife.

To , plant deep rooted plants to break up heavy soils and add organic matter. You can plant rhubarb, bear’s breech or other large leaf plants for a living mulch. Using wood based mulch on garden beds helps contain moisture in the soil, too.  To provide soil with nitrogen, plant ceanothus, clover, legumes like beans, and peas and lupine. To supply minerals as compost or mulch plant chives, comfrey, garlic and white yarrow.

Sustainable landscapes do not have to look like a weed patch. With a little planning your garden can be beautiful and productive.
