Shade sails – an airy, energetic and imaginative structure element in the landscape

By

Whenever I see the shade sails in this garden, I have the sensation of floating through the landscape, as though the patio was a ship sailing past islands of colorful plants and fun activities.  I also think of comfort; activities beneath these sails are protected from drizzle, fog and sunshine without being weighed down by heavy beams.

sail shades protect from UV rays and unwanted viewsCASE STUDY IN LA JOLLA

In the above backyard landscape design, the installer designed a combination of 2 super-imposed sails made to specs from sun-rated HDPE (high density polyethylene) fire rated shade fabric, sage green, both in a triangle shape. After determining the specific angle that was needed to block out the noon sun, one sail tip was attached with a strong stainless steel cable to the 1st story façade of the L-shaped house; a second point of attachment is on the roof of the lower arm of the L, where the actual anchoring was achieved by attaching to the roof beams.  The 3rd sail tip is attached to a steel post with a 4’-6” foot-deep base set in concrete that is hidden among the bamboo culms. Together both shade sails are very efficient at blocking the sun of the dining area, and their swooping outlines impart motion and energy to the landscape.

These sails can also be mounted vertically to block out a bad view; in this project the sails served to screen out the neighbor’s house that was looming behind the fence.

In cases where there is no house or roof to attach the sails to, free-standing posts are planted to which the sails are attached.

DETERMINING SHADE AND EFFICIENCY

The shade sails above were tested in a mock-up prior to installation. Other methods include “shade auditing” and  shadow mapping.

BENEFITS

  • Protection from UV rays (some fabrics offer up to 97 % UV protection);
  • Custom designed to fit the project’s requirements, in triangle, or trapezoid/square shapes (some standard sizes are available);
  • They represent cool landscape ideas that add value to the home and attractiveness to the landscape;
  • They can serve as vertical screen to increase privacy or block out a bad view;
  • They can be designed and installed to withstand high wind ratings.
  • Low maintenance: Yearly washing is recommended (some installers offer this service).

PRODUCT QUALITY
Every component of a shade sail is designed to stand up to the rigors of day in–day out exposure to the sun.  Many shade sails also have an up to 10 year manufacturer’s warranty against UV degradation.

DESIGN

As landscape designer San Diego, I love the contemporary character of these structures, their playful and even elegant forms and subtle colors. They make for an artistic statement, be it in a Mediterranean landscape, an eclectic “California mix”, or the landscape design adorning a modern home.

Since the sails can be mounted on roofs, façades or free-standing posts not planted in a fixed square or rectangle, I enjoy the artistic freedom that this allows my residential landscape design; these free-form shapes can totally transform a bland landscape into an architectural showpiece.

Successful Backyard Landscape Collaboration in La Jolla

By

How a homeowner with an artist’s love of beautiful details and a receptive landscape designer found synergy and fertile ground in the garden for a beautiful backyard landscape collaboration.

Successful Backyard Landscape Collaboration in La Jolla Sitting area by the pool

A couple of years after installation, this garden has matured beautifully.  I cherish the artistic collaboration with my clients; it contributes to very personalized and satisfying designs.  In this project, the teamwork was particularly fruitful, as Melissa F., entrepreneur, artist and singer/song-writer,  contributed an immense flow of creative ideas and suggestions.  The result is a garden that is beautiful and incredibly peaceful.

Melissa calls it her ‘outdoor home’ because it’s all here:  living room, kitchen, sitting room and lounge, and vivid plantings that make all come to life.

The previous backyard landscape design consisted of an uninspiring courtyard that a planter bed set in the middle made user-unfriendly.

Shade sails cool the dining area

Melissa and Todor love to cook and entertain outside.  To blend the outdoor kitchen seamlessly, we used bamboo facing, echoing the indoor flooring and the living bamboo hedge. Now, under the cool shade sails,  the outdoor dining area feels like it has always been there.

Despite of the many built elements the hardscapes do not overpower the garden and plants are allowed to soften all.

For each material selection we explored the idea of “weathering”, inspired by the mottled copper caps on eaves and fence posts and the home’s faded wood siding. The naturally rusted steel used for edging, planting troughs, fountain and gas lights provides that patina; matte concrete and exposed beach pebbles continue the theme.

Organized to allow for entertainment, relaxation and play, the garden creates a dynamic and sunny ‘outdoor home’ where plants add color, life and interest and prevent the built elements from overpowering the garden.

Bamboo hedge compressed

The bamboo hedge is a beautiful response to the construction of an oversized home in the neighbor’s yard that threatened the privacy and intimacy of this garden. The hedge helps focus the eye on the interior and defines the boundary of this backyard. It’s exciting to see how the black Bamboo stems echo the dark pavement in a wonderful contrast to the surrounding green foliage.

Most of the original overgrown “tropical” plants were removed and replaced with low maintenance plants, many of them from the sub-tropics.  This xeriscape landscaping was composed in colors of Melissa’s preferred color palette:

Forest Pansy Redbud, bronze Sedge and golden Kangaroo Paw, purplish Echeveria and in-ground Bromeliad with striking foliage. A few splashes of orange and red add highlights to the picture.

One of the landscape lighting ideas was to use steel “fire” troughs.  They provide light, warmth and entertainment after nightfall.  While their mottled rusty walls continue the theme of weathering, they also tie the different spaces together.

The steel fountain complements the materials used in the landscape and has a calming effect on all senses.

The fountain is a highlight of the garden

If synergy is  “the ability of a group to outperform even its best individual member”, then this residential landscape design is a beautiful example of how two creative individuals with their own aesthetics found common ground in the garden and created a product that will satisfy its owners for years to come.

Wow your mother with a plant that lasts – beyond Mother’s day

By

Browsing at my neighborhood garden center for a special Mother’s Day plant, I notice the pink and purple/lilac flower clusters of Hydrangeas strategically placed at the entrance. I’m impressed by their gorgeous petal ‘bombs’ and think that this old stand-by would probably wow my host, too.

But then a thought steels itself into my mind: How long will my gift decorate my host’s table?  Will she throw it away when the bloom is over, or will she plant it? This frilly one wants much more water than our rainfall provides, and many of our local micro-climates and soils are anything but easy on it. The farther away from the coast it grows, the sooner it will require shading from the hot afternoon sun, and then it wants coddling with acid-forming fertilizer to keep its color, and regular and pricey water.

Matilija Poppy

As landscape designer San Diego that practices xeriscape landscaping and sustainability, I love plants that wow me AND have a good ROI, that are attractive low maintenance plants for the low water landscape. Check out these:

Romheya coulteri Matilija Poppy in the drought resistant landscapeA Matilija Poppy Romneya coulteri  in full bloom makes your jaw drop, and bloom is now starting, right in time for Mother’s Day.  The fist-size flowers are carried atop 6-10 ft stems, for several weeks, exuding a strong fragrance of fresh apricots. This perennial shrub needs no additional water once established; it fits into all zones except mountains and deserts, likes sun or partial shade, and is adaptable to all soils except those that drain poorly.  Establishment can be difficult, but once successful, it will send out underground stems in sandy or rocky soil and more slowly in clay soil and is thus difficult to contain. It is best planted along barely cultivated margins, on slopes as erosion control, in dry areas or along parkways. It should be cut down to a few inches above ground in fall to remove old foliage.

Consider also our native wild lilacs, the Ceanothus family that equally fit well into xeriscape designs. The members of this group can be evergreen groundcovers or small trees; some species have brilliant blue flowers, others range in hues of purple, violet and white. They keep their great form year-round, survive the greatest summer heat as true drought resistant plants; they make valuable contributions to any habitat garden by providing food (butterflies, insects, seeds) and cover.

Ray Hartman Wild Lilac Ceanothus arboreus ‘Ray Hartman’  is striking with glistening green leaves, a height of up to 18 ft, and with rose-colored buds and profuse clusters of sky blue flowers. It grows reliably in both interior and coastal sites.

California natives bring a sense of heritage and a connection to the future; they have an incredible potential in all sorts of garden designs if we understand which plants perform in which conditions. With lots of different foliage, flower colors and textures they’ll make your garden interesting in all seasons, and with careful selection you can get year round color because some plant will be in bloom any time of the year. With little needs to additional water or maintenance they are choice candidates for the residential landscape design that satisfy us for years to come and have a high ROI.
