Ever wonder what your garden would look like if the human caretakers just vanished?
Maybe I’ve been inspired by all the disaster flicks like 2012 or the History Channel’s Life After People series. But envisioning gardens after gardeners is an interesting intellectual exercise that might help us answer that pesky question: What is a garden?
Would all the invasive species take over? Would the native plants reclaim their turf? For how long would you still be able to tell that a garden existed in a spot in the first place?
I looked at parts of my back yard and tried to imagine what would happen.
Within the first month, in Southern California’s dry climate, most of the potted plants would perish for lack of water. Some of the succulents might hang on longer, but without an extensive root system in the ground, they’d be doomed.
This little frog would be staring at a bog garden where all the bog plants have died back, once again for lack of water.
Within two or three months the fishponds would be dry: no waterlilies, no cattails, no sedges, no water for the local birds.
This pathetic patch of grass would go through boom and bust cycles, turning green with the rains, dying back to brown other times of year. Seeds of other plants better adapted to the conditions would eventually take hold. Maybe some plants from the local canyon. Maybe some hardy exotic or invasive species.
Behind the back fence of the house is this slope dominated by rampant iceplant. The the neighbor behind me and I haven’t been able agree on what to do with the space. I’ve planted a small collection of native plants to help stabilize the slope. These are species that with only once exception can be found within a five mile radius of the house, and include plants like this nightshade, Solanum parishii…
…and Del Mar Manzanita, Arctostaphylos glandulosa ssp. crassifolia, an extremely rare plant that’s on the Federal endangered species list. The neighbor, however, loves their iceplant and can’t imagine of a slope without this gawdawful invasive species clamoring all over it. The local chapter of the California Native Plant Society has prepared a great pamphlet on getting rid of iceplant that you can view [ here ]. It goes into some great reasons to get rid of the stuff:
Planted on hillsides of thousands of homes in San Diego, it has since crawled off the original site and into neighboring Open Space parks, endangering unique plants by smothering them. Iceplant provides little habitat value compared to the plant community that it is replacing. Compared to the native shrubs, iceplant has very shallow roots that do not hold soil well; close inspection often reveals gullies underneath the twisted mat of vines. After rain, Iceplant engorges with water, substantially increasing its weight. As a result, iceplant can cause the deterioration of steep hillsides by encouraging slumping – potentially endangering the house above.
For people in suburbia, “habitat value” might mean plants that harbor scary wild animals and bugs, so that’s not always the most compelling reason to go native. The fact that iceplant might endanger their property values could be more persuasive.
So, returning to my main topic, the iceplant would probably overrun most of the native plants in a very few years and form a deep pile. Once we neglected the slope for a few years and found that the mat of iceplant was starting to push the back fence over. Within ten years the fence would begin to fail and the iceplant would begin its descent into the lower garden.
These plants along the back fence would stand a chance of surviving without water. The yucca, palm, protea would be tall enough to survive an onslaught of marauding iceplant from behind. They’re plants that don’t require much maintenance, and this wall of foliage would probably look unchanged for a number of years. But the lower aloes and other succulents would likely be smothered by the iceplant.
This apricot against the back fence never looks great without summer watering, but it survives. It’s tall enough that it would probably survive the iceplant invasion. Some of the adjacent native plants do great with the natural conditions. They might not cope so well with the marauding iceplant.
The neighbor on the side has Algerian ivy that requires constant clipping to keep it next door. Within two years it would begin to establish itself in the back yard. Taller plants that might survive the iceplant invasion might have ivy crawling up and smothering them.
This raised bed near the house is where veggies and irrigated plants live. Most of the exotic plants wouldn’t make it without water. The Dr. Hurd manzanita, the bougainvillea vine and maybe the Garrya elliptica would probably hang in there, however, maybe for decades, maybe for much longer.
Fifty to seventy-five years out the house would start to fail. Plants might begin to move in. The surrounding garden space would be overgrown with the hardiest drought-adapted species. I almost never plant in rows, but the mixed origins of the species—South Africa, South America, Europe, as well as from all over California, not just local species—would clue an investigator into the fact that a garden existed on the site. The relationships between the plants would be dictated by nature, not a gardener preserving order between plants with mismatched levels of vigor.
Chances are excellent that one hundred years out, maybe two hundred or more, the most persistent invasive species would still be here. Iceplant and ivy, plus fennel and black mustard that have invaded the local canyons, would feature in the neighborhood landscape. But while many invasives bask in the newly disturbed earth of a garden or the re-engineered grades around roads, they don’t always do so well long-term. Biologists have suggested that many native plants would return to a place where they’re not being pulled out or constantly mowed. My yard might be colonized by the local Mexican elderberry, or toyon, or lemonade berry, or prickly pear. And maybe some of the plants I’ve already introduced to the yard will persist and reproduce. The restoration of nature might spread from my house and from the wild edges of nature just a few houses away.
Even after nature returns, the occasional hardy exotic plant surviving amidst the natives, along with some of the neighborhood’s plantings of trees and shrubs in rows will make it obvious: There used to be gardens here.

It’s the end of summer and most areas of the garden seem to be in some sleepy botanical torpor, exhausted from the heat. Not much is blooming. Brown is everywhere.
And then by contrast there’s this little over-performing corner, formed in large part by chunks of succulents that John has collected over the years…
Cascading over a back wall are the shocking red flowers of this crassula (I think it’s Crassula perfoliata var. minor, a.k.a. Crassula falcata). Its companions in this photo are a couple of other succulents, one of the goth-black aeoniums (Aeonium arboreum ‘Zwartkop’) and what’s likely Graptopetalum paraguayense. The three are pretty easy to find and like nice combined.
After the winter rains the foliage on all of these plants plumps up and looks pretty spectacular. But as summer settles in the aeonium and and graptopetalum drop their larger leaves in favor of a tight cluster of leaves packed at the growing end of the stalks. The bigger the leaf the greater the water loss. The crassula will retain its leaves, however, although they’ll look a little shriveled in the drought. The fact that the leaves are folded in half probably helps to shade the leaf, reduce transpiration and reduce moisture loss.
The flowering of the crassula varies by year. The photo above is from this season, actually not one of the better years. To the left is a shot from last August. This year’s not quite as flashy, but in the slow heat of August and September, I’ll take it.

After finishing my coffee and reading some of the newspaper this morning I took a quick survey around the yard.
Honey bush (Melianthus major) is a South African species that I’ve had for a couple years now. Although it responds to watering with a lot of spunky growth, it’s also good with minimal additional watering. I have two sprinkler heads in the garden, and this plant gets by on the overspray from one of the heads after it’s made the sages and tangerine tree happy.
The maroon flowers unfurl from the branch tips in spring and dry to these brown spikes. I’ve left them on the plant to help me decide if I like the way they look or not. The bed they’re in in has a lot of mounding plants, so the spikes give some vertical interest.
The leaves are heavily serrated and are the main reason for growing the plant. Here they are, with shadows, and backlit by the morning sun. They look a little fierce, but they’re actually soft, like rubber. They do have a bit of an unpleasant odor if you brush by them. Combine that fact with the plant’s eventual size—six to twelve feet—and you’ll see that it has “dramatic background plant” written all over it.
The melianthus grows next to a bromeliad that truly is nasty and spiny. (I’ve mentioned this plant before…) Pretty though, even when it’s not flowering. And it takes next to no water when grown in mostly shade.
Next to the honey bush and bromeliad, in a planting that spans two or three continents, is a young manzanita, Actostaphylos Dr. Hurd, shown here in a detail highlighting its exfoliating bark. Although one of the faster growing manzanitas—it’s grown eight inches since February—this still isn’t a plant for the impatient. Currently it’s exactly one meter tall, and will hopefully hit its design height of ten feet before I’m back diapers. Eventually it’ll make it to fifteen feet or more.
In the front of the same bed, next to a sprinkler head, are some basil cuttings that I’ve posted on before. Six weeks after planting out, the largest plant is maybe eight by eight inches and is big enough for me to consider taking an occasional snip for the dinner table. In a month I should be ready to make batches of pesto.
The final photo isn’t my garden, but looking across the street, where they’re installing plastic turf. The neighbors are responding to our new water restrictions by mixing synthetic grass with palm trees. The look will be something like the wet Hawaiian paradise they had before.
But I do worry that synthetic grass, even if it looks something like the real thing, does nothing to address people’s fundamental expectations of what a garden should look like in a fiercely dry climate. And in my most uncharitable moments I think that installing plastic grass is like treating heroin addiction with methadone. And to this gardener, installing something as dead as plastic grass lands with a thud as loud as the one created by the infamous 1978 remodel of a Sunset Boulevard mansion by a Saudi sheik that featured planters full of plastic flowers.
But hey, they’re doing what makes sense to them, and they will be reducing their water use.

Water restrictions went into effect here in San Diego on June 1. So far there’s a short list of thou-shalt-nots, and the water district has primarily targeted landscape irrigation, the low-hanging fruit, with directives like: no watering between 10 a.m. and 6 p.m., watering only on specified days based on your address, sprinkler-watering limited to no more than 10 minutes, three times a week.
Walking around my neighborhood I can see a lot of people who’ve responded to the call. Some are just beginning to make changes, while others made changes years ago.
I was down a couple streets from my house when I saw this front yard makeover. Simple. Just a few big plants chosen for their countours. This is a house where the modern lines of the house echo the style of the plantings. The sago palm requires some water, but the other plants would do well going dry.
Walking around I saw a number of houses where more drought-tolerant plantings were making their way into the landscape. Each house seemed to have their own take on what a drought-tolerant front yard could look like.
Some relied on hardscape to replace a lawn…
…some went in for lots of mulch instead of a lawn, but not many plants…
…some for mulch with some plants, drought-tolerant or not…
…many of the yards that were reimagined as dry landscapes many years ago seemed to rely on gravel and some plants…
…several used gravel with just a few plants to image a desert theme…
…this one mixed gravel, junipers, and edible landscaping—a fig—right out front…
…many used what I’d consider a contemporary look, employing widely-spaced drought tolerant combining natives or exotics set in mulch or DG…
…here’s another of the style where a few plants are set in the middle of space they’ll never grow into. It’s definitely a look, as well as landscaping that embraces the fact that things don’t need to be densely planted to look good…
…many yards feature some more water-intensive plants mixed in with ones that require a lot of water, a kind of planting that a drip irrigation system can make possible. These people used some roses along with plants that’ll look good with less water.
Looking around you sense that this is a neighborhood in transition. Some people are just letting their lawns go brown. Some may be planning on redoing their plantings. Others are probably just waiting out the water restrictions to go back to their old ways.
Some houses are still attached to their old ways that feature conspicuous water consumption. Maybe at some point its was a status thing, showing everyone that you could spend resources on something that can’t be used. But these days it’s hard not to feel a little hot under the collar when these are resources that are being taken from the rest of us.
Still, before I get overly tough on the neighbors, I want to give people the benefit of the doubt for a while. These are tough economic times. Redoing your landscaping can be an expensive proposition. And there are people for whom dealing with a sprinkler timer would be like asking them to pilot the Space Shuttle. (My father could never figure out his timer.) And there’s a chance that people haven’t heard about the new restrictions.
But there’s one water-user that I’ll call out on the carpet. This is our local shopping center, which presumably is maintained by people who know what they’re doing. But watering the sidewalk and the asphalt…
…and then letting all the water run off into the storm drains, well, that does get my goat. But it’s not like I’m only grousing on a blog they’ll probably never read. They’ve heard from me already, and I hope they’ll get in step with the neighborhood they serve.
But overall I’m pleased. People are getting the message and they’re doing something about it. I think they get a sense that we’re all in this together, and we’ll find ways to deal with this water crisis. Not living in a neighborhood ruled by a homeowner’s association, you can see that we’re all finding different solutions.
Some choices will be better than others from the standpoint of water use, habitat, urban runoff or reducing the heat island effect. Still, it’s encouraging to see people people waking up from this fantasy of a lush, green, subtropical California of endless water resources.

Is there anything better than fresh herbs from the garden?
For years I had herbs in my fairly dry veggie garden. Some of the herbs herbs thrived. Others sulked. Some died.
Fortunately, if you’re trying to cut down on watering, you still have a huge number of herbs to choose from. For instance, many of the plants that you think of immediately when you hear the word “herb” originate in the Mediterranean, and many of them prefer less moisture than other garden plants.
Below, I’ve listed some common herbs that have done well for me dry spots, along with others that I’ve seen doing well in quite dry conditions. There are lots of other selections, but this list can get you going with more than a summer’s worth of recipes.
- Rosemary (Rosmarinus officinalis): You can pick from forms that sprawl, form a shrub, or grow straight up in spires.
Sage (Salvia officianalis): European Garden sage comes in lots of versions in leaf color (green, golden, tri-color or purple) and flavor (“sage” flavor, pineapple, or grape).- Oregano (Origanum vulgare)
- Marjoram (Origanum majorana)
- Thyme (Thymus spp.): Some thymes, including many of those sold for ornamental groundcover use (such as T. serpiphyllum) are only slightly scented or not at all. The culinary bush forms generally have more scent and flavor, and they come in a wide range, including lemon and lime. They also tend to be more tolerant of dry conditions.
- Lavender (Lavandula spp.): There are several lavender species, as well as plenty of hybrids and varieties. All are at least somewhat drought tolerant. Some extremely so.
Scented geraniums (Pelargonium spp.): Take your pick of rose, apple, cinnamon, nutmeg, pineapple, lemon, lime, apricot and others.- Wormwood (Artemisia spp.)
- Mexican oregano (Lippia graveolens)
- Fennel (Foeniculum vulgare): Beautiful and tasty plants, but they’re considered invasive in many locations (including the entire California floristic province). Research before you plant! There’s an attractive bronze version that’s reputed to be less invasive. Still, I wouln’t plant it if regular fennel is a problem in your area.
- Nasturtium (Tropaeolum majus): With edible, peppery leaves and flowers, some people consider this an herb. As with fennel, above, it can be invasive. Don’t plant it if it could escape. (Many of the moister hillsides here in San Diego are covered with the stuff.)
- Lemon grass, both West-Indian (Cymbopogon citratus) and East-Indian (C. flexuosus): Sources tell you these plants like water, but I’ve found that they don’t mind going dry occasionally, especially if they’re given some shade.
Good eats!

Olivier and Clara Filippi have been gardening in the south of France for well over a quarter century. Theirs is a mediterranean climate, and their nursery, Pépinière Filippi, located near Montpellier, specializes in plants adapted to the dry-summer/wet-winter cycles that you find in only five large regions on earth: the Mediterranean zone, proper; South Africa; the southwest corner of Australia; Chile; and much of California.
When I picked up Olivier Filippi’s recent The Dry Gardening Handbook: Plants and Practices for a Changing Climate, I was expecting it to be a different sort of book than it is, maybe something about general drought-tolerant plants, or a volume dedicated to helping your garden adapt to using less water. What this is, however, is a straight book on mediterranean gardening and plants suited to mediterranean climates—something that probably shouldn’t come as a surprise since that’s the focus of the author’s nursery.
There’s a brief introduction to what constitutes a mediterranean climate, followed by notes on the strategies plants use to survive and thrive in it. Good advice on planning, planting, establishing and watering a new mediterranean garden comes next. Then Filippi gives us the heart of the book, a listing of over 400 mediterranean-adapted species, containing common and scientific names, approximate mature plant sizes, and notes on cultivation and propagation. (If you can begin to read French, you can check out the online catalog at the author’s nursery, which closely mirrors the list of plants recommended in the book. There you’ll also find some of the advice that’s offered in the book, although without the nice photos in the book.)
Olivier Filippi gardens in France, and the plant list definitely Eurocentric: lots of different lavenders, cistus, phlomis, for example, with relatively few plants from other the other great mediterranean regions. In fact, many of the non-Mediterranean mediterranean-friendly plants listed are drought tolerant selections from several non-mediterranean climates. For gardeners in dry climates that don’t undergo mediterranean cycles, these suggestions might be some of the best options to try. But those plants might not the be greatest of discoveries: Photinia, heavenly bamboo (Nandina domestica), red-hot poker (Kniphofia sarmentosa) and American gaura (Gaura lindheimeri), for instance, are probably already common offerings in many American nurseries.
One of the book’s most outstanding features is the use of a “drought resistance code” that assigns a number from one to six to each of the species in its plant list. Based on work by plant geographer Henri Gaussen, the number quantifies the number of months of the year a plant can be expected to survive under drought stress. The book also contains instructions on how to calculate the climatic profile of where you live. (I figured out that my coastal San Diego location exerts a 3.5 to 4 drought stress factor. (Edit May 20: I oopsed on my figuring for coastal San Diego. My revised number is a much dryer drought stress factor of 6.)) All that’s a really useful way to understand drought.
When you see plants sold in nurseries and catalogs as drought-tolerant, the description can be meaningless. A variety that would go fine for two weeks without water could turn into seasoned kindling if subjected to six or seven months of continued drying. Realizing that a “drought-tolerant” chamomile plant has a drought resistance code of 2 would begin to tell you that it wouldn’t thrive in the same conditions that would suit California’s more “drought-proof” Romneya coulteri, which has a drought resistance code of 6. Having that information could help you plan companion plantings, as well as help you avoid plants altogether that would only lead to expensive mistakes.
Coming at plantings from a mediterranean focus leads the author to say some choice things about lawns:
You don’t have to be a visionary to see that the traditional lawn is an absurdity in mediterranean climates. If you nurture a deeply rooted feeling that you can’t be happy without a vast, lush lawn, then perhaps you ought to consider going to live in Cornwall… People often imagine that they need a huge expanse of lawn, but all too often the only person who walks over a traditional lawn in its entirety is the unfortunate individual who has to mow it every Sunday.
The author’s solution? Landscaping that pays attention to where you live. For those of you in mediterranean climates, this book can help you develop a deeper understanding of what’s unique about your environment. It can help you come up with good plant choices compatible with what your location offers. Along the way, it could help you save water, reduce pesticide use and maybe even free up some of those Sundays you spend mowing the lawn.

For this Garden Bloggers’ Bloom Day I’ve picked some predominantly purple spring-flowering plants that are starting to do their thing in my garden. All but one of these are California (or Baja California) natives, and all would be seriously water-wise choices for the garden. Some would even make it through an entire summer without water, though they’d look just a little better with a sip once or twice a month.
Blue-eyed grass (Sisyrinchium bellum): What a great name for a great plant. This iris relative is happy coexisting in a moderately-watered garden with other plants, though they can stand drought. Here they are living alongside some chard and heliotrope.
Blue dicks (Dichelostemma capitatum) are common here near the coast and are one of our reliable signs that it’s spring. They self-sow and spread around the garden, but not obnoxiously.
Black sage (Salvia mellifera) is one of the local canyon plants that’s earned a place in the garden. In life the flowers are a slightly stronger pale mauve color than here in the photo. It’s just beginning to come into flower and should be a little more intense in a couple weeks. Though not one of the “look at me” sages, it’s still quietly beautiful.
Verbena lilacina originates in Baja. The plant shown here is just getting started. It should flower much of the year and require very little summer water.
This one’s maybe closer to blue than purple, the South African bulb Morea tripetala. I stuck it in a really dry spot, and it’s now probably just blooming on the reserves in the bulb. We’ll see how well it does after a season of tough love in the garden.
And with the last photo we come back to California with the justifiably ever-popular Penstemon Margarita BOP (sometimes sold as Penstemon heterophyllus ‘Margarita BOP’). The flowers are a wild mix of blue and magenta pink, giving the overall impression of purple. The open tubular flowers have something of the look of a foxglove which would require a certain amount of water, but this penstemon actually does just fine with almost no added water.
Thanks to May Dreams Gardens for hosting Garden Bloggers’ Bloom Day. Check out the page with glimpses into what’s blooming all around the world.

Here’s a look at a new groundcover I’m trying out. The plant, Nuttall’s milkvetch (Astragalus nuttallii) is native to coastal Central California, and seems to be adapting easily to my coastal San Diego location—maybe a little too well!
Las Pilitas Nursery, who seems to be the only firm propagating the species, estimates its height to be 3-18 inches and 18 to 36 inches wide. The plant went into the ground October 12, and has topped out at a foot or so high—so far so good. But its spread, now at over six feet, has easily hit more than double the estimated maximum plant size. And that’s with no supplemental watering after the first couple of months in the ground. We’ll see if it slows down as the weather warms and the ground dries out.
The milkvetch bore some of these small, ivory-white flowers on it in October, and it’s never been without them in the intervening six months. Now that the weather is warming, the plant is getting even more interested in flowering.
As much as I enjoy its flowers, my favorite thing about this milkvetch is its delicate foliage. It’s fern-like, and so far has maintained its clean, green-to-grayish green coloration. I have the plant at front edge of the retaining wall next to the front sidewalk, so it’s easy to get face to face with the flowers and leaves. A front of the bed location would also let people enjoy this delicately textured plant.
So, if you’d like a distinctive, delicate, low, mounding groundcover for a dry spot in a zone 9 or 10 landscape, this might be just the ticket, even if the plant might get a little wide and need to be cut back.
PS: I should also mention that one of this milkvetch’s common names is “locoweed,” and the plant is supposedly poisonous. I have no idea whether it’s in the category of nightshade or no more dangerous than tomato plants. Since I have no small children around or pets that get into anything other than catnip, I’ve never let an interesting plant’s supposed toxicity stop me from growing it. But you might consider that before planting a couple acres of it.

January can be an amazing month for succulents and other desert plants. Many aloes and agaves explode into bloom, and plants with ephemeral foliage are green with leaves in ways you don’t often see them.
San Diego’s Balboa Park houses one of the prime local collection of cacti, succulents and other desert dwellers from around the world. The Desert Garden, the larger of its two succulent gardens, was established in 1976, but many of the plants are senior citizens much older than the age of the garden.
Aloes star in its January landscape, with red and orange torches of flowers that double as hummingbird magnets.
And shown here, lurking in the shadows, is one of the local hummingbirds, staking its territory.
Among the big, mature specimens are several dragon trees, Dracaena draco. In this first photo, on the near trunk, you can see a reddish patch where the plant’s red sap has dried. When cut, these plants ooze a fluid that in some European legends was purported to be dragon’s blood, hence the plant’s name (draco = dragon).
This is a public garden, and so it’s subject to funding glitches and battles over civic priorities. I’d consider the garden to be in great condition considering those limitations.
One thing I would have loved to have seen, though, would be more plant labels. I encountered so many interesting species, but very few of them had name tags. I have this thing about needing to know the name of a plant—Call me compulsive. But the lack of labels drove me crazy. I realize, however, that tags don’t come cheap. And in a wide-open public garden, labels can walk away with pieces of succulents in the hands of evil plant addicts.
One of the plants that was labeled was this Natal Bottlebrush, Greyia sutherlandii. A bit scrappy-looking as a plant, but what great flowers!
Also labeled was the Madagascar ocotillo, Alluaudia procera. I loved the spiral patterning of its spines.
Another problem with this being a public garden is that there are quite a few specimens where people’s temptations to carve their initials in the plant life got the better of them. This euphorbia was scarred many times over. But that wasn’t going to stop it from blooming.
After visiting the garden I was surprised by how many shots I’d racked up in the camera. And for some reason, the majority of them were verticals. Is there something about succulents—particularly the upright-growing kinds that mimic the way a human stands—that scream out for photographing them in an upright orientation?
Some yuccas, I think, with spent bloom stems.
Boojum trees, Fouquieria columnaris, native to Baja California. This plant is in the same genus as the California desert’s spectacular ocotillo, which interestingly isn’t related to the Madascar ocotillo, above.
Aloes and kalanchoes in bloom.
The main garden is a flat, easy stroll over wide decomposed granite pathways. As part of a recent expansion, the garden now also includes this switchback down into Florida Canyon, also part of Balboa Park. The plants along the descent are still young, but should look spectacular in a decade or so.
Not everyone in the world loves cactus and succulents. They might point to the defensive spines many of the plants have, and they might say the sculptural shapes of the plants don’t look soft and cozy like leafy shrubs or fragrant roses. 
Next to the Desert Garden is Balboa Park’s rose garden. During springtime, thirty seconds of walking would take you from the world of cactus and succulents to a garden manic with flowers and heavy with the aroma of roses. But on this bright January day, the adjacent roses were pruned down to naked stems and piercing thorns. It was the cactus and succulents that looked warm and welcoming.
The Desert Garden is located across Park Boulevard from the Natural History Museum on Balboa Park’s museum row. The garden has no walls, no entry fee, and is open 24/7, 365 days of the year.
If the 2.5 acres of the Desert Garden isn’t enough of a cactus and succulent fix, cross Park Boulevard and take a stroll over to the Balboa Park Club, maybe ten minutes on foot, and take in the parks original 1935 cactus garden, which, according to the park’s website, was established “under the direction of [San Diego gardening legend] Kate Sessions for the 1935 California Pacific International Exposition.” There you’ll find “some of the largest cactus and succulent specimens in the Park,” along with a nice collection of proteas.

Here’s a post in commemoration of today, Black Friday, the day after Thanksgiving when the holiday shopping season gets going in earnest.
When one of Southern California’s first Ikea stores opened at the Tustin Marketplace in Orange County twentyish years ago I was excited. I’d been oversaturated with the cheap, ugly department store merchandise that was available in my budget range at the time, and the simple and rational Ikea designs wafted in like a breath of Nordic oxygen.
The buildings of the Tustin Marketplace were different from anything I’d seen at the time. They were huge and painted in intense colors of the earth. Although the architecture shared some of the color sensibilities of postmodern architecture of the 1980s, it was nothing like what was being done in suburbia at the time. The central landscaping was also distinctive: geometric, spiky, sculptural. Once again, this wasn’t straight out of the rulebook for how you do landscaping for a suburban shopping center.
I had seen designs by the Mexican architect Ricardo Legorreta in architecture magazines, and the complex in Orange County reminded me a lot of his work. Little did I know until fairly recently that he actually was responsible for designing the complex. On my last trip up to Los Angeles I made a point of stopping by the stores on the way home. Unfortunately, the Tustin Marketplace hadn’t aged gracefully.
Tustin Marketplace: Where Linens
The Ikea was long gone. One of the main roads into the complex dead-ended at a stark earth-red wall, easily forty or fifty feet tall, that bore the ghostly remains of where a Linens ‘n’ Things store sign had been removed. I’ve never visited the pyramids of either Egypt or Central America, but this is how I imagine it would feel: overpowering, desolate, scaled to some overinflated sense of human self-importance.
It was late on a Sunday morning and most of the remaining stores were just opening up. It’s the time of day when you’re confronted with the acres of blank, blank, blank asphalt that make up so many of this country’s retail landscapes. This is land that lies barren and unused for fifty weeks out of the year and only springs into use for those few and intense days of holiday shopping.

But not everything was overwhelming bleakness. The parking area next to the food court sported this dense grove of palm trees. The space made me think of the agricultural groves where dates are grown Indio, south of Palm Springs, in their sense of graceful geometry overhead and shelter from the elements. Pretty good for a retail parking lot, I thought.
Real landscaping with fake grass
A few of the geometrical landscaping details remained from the original design. In the first of these, the original sloping lawn had been replaced by one of the artificial lawn replacement products out there. It looks real enough when you’re zooming by in a car, but even with its hype of looking better than Astroturf, it’s nothing I’d want to have to stare at from the windows of the house.

And here, in the parting shot of the shopping center, a row of white monoliths marks the transition from the parking lot to the public street beyond.
So, is the Tustin Marketplace a great example of architecture or landscape design? I’d argue no. Even though it’s right on Interstate 5, I wouldn’t go out of your way to visit it anymore unless you need a snack or bathroom break from the freeway. But the complex was different in its day, and I give it points for that. Additionally, the landscaping didn’t require much water to sustain it.
Interestingly, Ricardo Legoretta was behind the late 1980s redesign of Pershing Square in Los Angeles, one of the city’s historic open spaces and a past gathering point for a diverse mix of the population. Several years ago I attended a conference at the Biltmore Hotel, which is located on the square. Even at that time Legorreta’s huge slabs of concrete that had been painted purple looked hostile and dated. Pershing Square was another of the architect’s public spaces that hadn’t aged gracefully. There’s now talk of replacing the design with something else.
