Mid-century house inspires Palm Springs-style garden in Austin

Charlotte Warren, a photographer and former co-chair of the local Garden Conservancy tour, inherited a steeply sloping, west-facing zoysia lawn when she moved into her home in the hills of West Austin. Aside from requiring lots of water and regular mowing, the lawn offered zero privacy for her front-yard swimming pool and did nothing to complement the mid-century lines of her 1957 Barton Riley-designed home.

Inspired by the Palm Springs, California-style architecture of her house, Charlotte hired landscape architect Curt Arnette of Sitio Design to create a garden in the modern, desert-oasis style for which Palm Springs is known. In the summer of 2013, the zoysia lawn was ripped out and the new garden installed. I visited just a couple months later, in October, to photograph it. Those photos appear in the first half of this post. But I have a treat! I was invited to visit again last week and took new photos, which make up the latter part of this post, offering you before-and-after views of the garden’s growth over one year.

Let’s take a tour, shall we? A small, emerald lawn still offers barefoot pleasure under the live oaks near the house and pool, a non-guilty pleasure considering the water thriftiness of the rest of the garden. Mod circles of crushed gravel act as stepping stones across the rubbly, native river rock that mulches the dry garden.

Where the zoysia lawn once crisped in the afternoon sun, now an inviting, steel-edged, crushed-gravel path sidewinds through the sloping lot, with steel-riser steps leading down and back up to the house.

Desert plants like Yucca rostrata, agave, and golden barrel cactus and drought-tolerant natives like Texas mountain laurel, Wheeler sotol, blackfoot daisy, prickly pear, Mexican feathergrass, and frogfruit create a buffer between house and street, hold the slope (no retaining walls were added), and lushly mingle to create a Cal-Tex oasis.

The pool is situated in front of the house behind turquoise railing, overlooked by the front windows for a year-round poolside view.

These steps lead down the slope, where the gravel path continues back toward the driveway. Enormous, rounded granite boulders, which look as pillowy as rising bread dough, edge the steps and are placed as accents throughout the garden. Along the property line, Arizona cypress creates an evergreen screen.

Graceful steps entice you to keep exploring.

On any sloping lot, water runoff is a design challenge. Terracing is one answer, but it’s expensive. In this unterraced garden, boulders help slow water flow as do the plants, and a channel filled with riprap collects remaining runoff, ducks under a metal bridge in the gravel path, and moves it downhill off the property.

Xeric plants like ‘Macho Mocha’ mangave and Mexican feathergrass are given room to grow and spread.

Blackfoot daisy spills over and softens a cluster of boulders.

Looking up from the street. The white-flowering tree at right is Mexican olive (Cordia boissieri). Because it’s native to South Texas and can be damaged in hard freezes, this is one tree I’d plant in spring rather than fall.

It is quite pretty.

At street-level, Mexican feathergrass mixes with agave, mangave, sotol, leatherstem (Jatropha dioica), and blackfoot daisy.

The golden eye of blackfoot daisy finds a color echo in golden barrel cactus.

One year later: August 28, 2014

That was then. This is now, one year later, on a sunny, 100-degree summer afternoon. Despite the heat, a breeze kept me comfortable, and the winding path is as enticing as ever.

The groundcovers and grasses have put on the most growth over the past year. The native shrubs and small trees have also noticeably grown. Other plants have been replaced, as is typical in any garden. A shrub along the top path, for instance, has been replaced with the cleaner lines of an ocotillo, a desert plant I don’t see in Austin very often.

The switchback. Architectural Yucca rostrata serves as a focal point at the turn.

The Texas mountain laurels have grown a foot or two, and will eventually screen the left side of the pool.

Yucca rostrata shadow play (“Look at me! I’m a sun!”) on a puddle of silver ponyfoot.

A new perspective, looking down the steps. Notice that much of the gravel mulch is now hidden under a layer of creeping groundcovers, softening the look of the garden.

The steel bridge and riprap channel. I imagine this becomes a torrent during a typical Texas thunderstorm.

Looking back at those pillowy boulders and shimmery Yucca rostrata.

One more view, with the bridge. Blue-greens and silvery blues visually cool the garden, plus those plants tend to be most drought-tolerant.

Powder-blue Wheeler sotol dances uphill on either side of the riprap channel.

Yucca rostrata should always be planted where it can cast a shadow.

‘Green Goblet’ agave sits atop granite boulders, with golden barrel cactus below.

The garden continues in a curving band on the other side of the driveway. It makes for a continuous garden view at the juncture of strolling path and driveway.

Water runoff along the driveway is handled with another channel and heavy stone that won’t wash downhill.

At streetside, groundcovering Mexican feathergrass and frogfruit have filled in nicely, and the feathergrass has gone tawny for summer. The structural agaves grow more slowly, but in a few years they will dominate this scene.

On the right side of the drive, silver ponyfoot cascades around boulders and plants like a living waterfall.

Up near the house, a trio of large steel-pipe pieces act as planters for silver and bronze dyckias.

A silvery-green, textural composition of ‘Whale’s Tongue’ agave (A. ovatifolia), purple prickly pear (‘Santa Rita’ opuntia, perhaps?), and silver ponyfoot (Dichondra argentea).

My thanks to Charlotte for inviting me back to see how her garden has grown. It’s heartening to see a garden that looks just as happy after weeks of triple-digit heat and no rain as it does in fall or spring. Charlotte told me she waters once a week via a drip system that delivers water directly to each plant. I imagine by next year, the dry garden could easily go two weeks between waterings in summer and look just as fantastic, and of course it wouldn’t need to be watered at all in cooler, wetter times of the year.

Plant This: Candy lily blooms are a sweet surprise

Visiting the garden of my friend Cat/The Whimsical Gardener earlier this summer, I exclaimed over a dainty, freckled flower on a long stem, with the sword-like leaves of an iris. Candy lily, she said, adding that she took no particular care and it thrived in morning to mid-afternoon sun. I was smitten.

By happy coincidence, a week later Katina of Gardening in Austin mentioned on Facebook that she’d seen 4-inch pots of candy lily (× Pardancanda norrisii) on sale for $.99 at Barton Springs Nursery. Despite the fact that late June is way past my stop date for planting anything except cactus or succulents, I drove straight there to buy a dozen, not knowing or caring what color their blooms would be. I planted some in my front garden (risking deer foraging), some in the back (risking too much shade), and gave the rest to my mother to try in her garden. I watered them in well and then left them alone except for our allotted once-a-week irrigation.

Last week I was surprised and delighted to see a bloom stalk forming on one of the candy lilies in the front garden, and two days ago it bloomed! I didn’t expect it to flower in late summer, nor so soon after I planted such a small plant. Now another one is putting up a flower stalk.

Each bloom lasts just one day, but online sources say candy lily has a long bloom period. I don’t know whether late-summer blooming in my hot climate is typical or unusual, so if you have experience with this plant in central Texas, please comment; I’d love to know more. What I do know is that candy lily is a man-made hybrid of blackberry lily (Iris domestica, syn. Belamcanda chinensis) and vesper iris (Iris dichotoma, syn. Pardanthopsis dichotoma). Despite its name, it’s not a lily but rather in the iris family. It’s said to be short-lived but may seed out. I hope so. I’d love to have more, especially if it turns out to be as deer resistant as iris.

While I was out front admiring the candy lily, I noticed an old favorite also going strong in the driveway-island bed.

Pale pavonia (Pavonia hastata), the Brazilian cousin of our native rock rose (Pavonia lasiopetala), has tissuey, pale-pink flowers with a wine-colored eye and veins. In favorable conditions it seeds out prolifically, but in my fairly dry garden it doesn’t overseed its welcome.

Deer leave established plants alone (in my garden at least), but they occasionally sample young seedlings I’ve planted. Hard winters sometimes kill off pale pavonia. Luckily a few seedlings always seem to pop up in spring to keep these lovely, hibiscus-like flowers coming.

Inspiration for my new bottle tree comes from the desert

When it’s too hot to plant, consider planting a bottle tree. It’ll never need watering, and the more the Death Star shines on it, the better it looks.

I made a simple, post-style bottle tree 5 years ago. But the cedar post was rotting, and it was beginning to list. I decided to replace it, and as I pondered my options I remembered a plant I admired at Big Bend National Park and in Phoenix last spring. Suddenly I knew what I wanted.

An ocotillo bottle tree! Poetic license means its blooms are blue instead of red, but I like the organic, vase-like structure — a nice change from my former stylized tree.

Bob Pool of Draco Metal Works (and a blogger at Gardening at Draco) constructed it to my specifications: upright rebar “branches” welded to a metal base, about 8 feet tall by 6 feet wide, with a base that can be anchored to the ground with rebar stakes. He did a great job bending the rebar to give it an ocotillo’s form.

After setting it up yesterday afternoon in 100-degree heat, I jumped into the pool to cool off and admire it. As often happens while studying the garden while neck-deep in cool water, I decided to rearrange a few things, starting with the yellow motel chairs that used to sit off to the side in the shade. I moved them front and center to create even more of a long-view focal point with the bottle tree.

And I moved my red-orange Circle Pot over by the orange-blooming Mexican honeysuckle for a hot color echo. Hmm, what other art or seating redos can I come up with until it’s cool enough to plant?
