The art-adorned, water-saving garden of Mireille Engel


Last week I had the pleasure of visiting a new garden, that of Mireille Engel, a French-speaking Swiss native turned Texan and longtime gardener, whose garden helper, Kathy Christian, introduced me and gave me a tour. Located in the Cuernavaca neighborhood and perched on the edge of the Hill Country, Mireille’s garden surrounds a horseshoe-shaped compound of two houses connected by a breezeway that she shares with her daughter and son-in-law, the architects who designed this unique home.


Sustainably constructed of straw bales, the stuccoed house is bisected by a stone buttress wall, which stretches into the front and back gardens. It was inspired partly by the architecture at the Lady Bird Johnson Wildflower Center, Kathy told me.


An arched opening at the base permits views through the wall and is filled, moat-like, with a pond that extends on either side. (See top photo for a side view.)


The lily-filled pond is fed by a tall, stacked-stone waterfall built into the uphill slope, attracting birds and other wildlife with its steady dripping. In the xeric beds along the slope, large agaves and ornamental grasses provide structure and movement.


Kathy explained that dozens of junipers (known locally as cedars) were recently removed from the front garden, and a new native-plant garden designed by Christine Ten Eyck is filling in. Where the junipers once crowded out everything else, now a diverse assortment of natives attracts pollinators and birds and was showing some late-spring color from wildflowers like pink evening primrose. The garden was supplied with an irrigation system to get it established, but the goal is for it to be self-sustaining in a few years.


If you could leap over the roof, you could follow the line of the buttress wall through the house and into the back garden, where it extends into the landscape with a gutter running down the center. It must be a delight to see water spilling down like a waterfall when it rains.


The collection of water is key to this green-built home’s design, actually. The metal roof slopes to the back of the house (pictured here), and gutters collect rainwater and send it via underground pipes to an enormous cistern behind the swimming pool, at the low end of the property. After being filtered and cleaned, the rainwater is reused for drinking, showering, and other indoor use. In fact, the home has no access to city water at all. All of its water is provided by rainwater collection and one small well. Considering there is a swimming pool to keep filled, that’s pretty impressive!


Behind the pool stretches a lovely Hill Country view. The rainwater-collection cistern keeps a low profile in the foreground, its concrete cover painted with a yin-yang design. I don’t remember how many gallons it holds, but it must be a lot. Overlooking the scene towers a female figure, a sculpture called “Rosetta Welcomes the Sun.”


Rosetta is one of several Bobby Bacon metal sculptures that Mireille has collected, and it’s monumental, around 20 feet tall.


Mireille delights in garden art, which is thoughtfully placed throughout the garden. I particularly like this oversized bouquet of metal-and-glass flowers alongside the house. Bluebonnets, ‘May Night’ salvia, and purple heart echo the blue glass of the flowers.


Mexican feathergrass tosses its blond tresses below the vase.


In the lush center of the garden, tough cottage favorites like iris, roses, and fruit trees mingle with natives like Anacacho orchid tree and square-bud primrose.


Grass paths wind through large planting beds.


Along the driveway, toothless sotol (Dasylirion longissimum) and prickly pear add architectural form and rarely, if ever, need watering.


Colorfully painted walls remind me of the Mediterranean or Mexico…


…giving the garden a hint of tropical retreat.


A terracotta goat pot and yellow wall say Mexico.


But oil rig wall art says Texas!

I adore this spotted manfreda…


…and this creamy rose…


…and the raspberry paint on Mireille’s porch wall.


But the pièce de résistance is her yellow-tiled outdoor shower, complete with a jewel-toned ceramic lizard, whose open jaws helpfully hold the soap!


It’s the creation of ceramist Claudia Reese, a local artist whose work Mireille collects.


What a delightful and unique garden to explore, filled with art, interesting architecture, and native and waterwise plants. My thanks to Mireille for sharing it with me and to Kathy for the introduction and the tour!

Going waterwise at Rollingwood City Hall


Putting their money where their mouth is, more and more cities that urge citizens to reduce their water usage are replacing thirsty lawns around courthouses and city halls with xeric landscaping. Rollingwood, a tiny city of around 500 homes just three miles from downtown and surrounded by greater Austin, is setting a fine example with its new City Hall Waterwise Garden at 403 Nixon Drive, installed in autumn 2013.


Not every city has the wherewithal to get the famous Ogdens — part-time Austin residents Scott Ogden and Lauren Springer Ogden of Plant-Driven Design — to design it, however. Hired by the city, which received $16,000 in donations from residents (about half of the total design and installation cost, according to the Statesman), the Ogdens collaborated with local designer Patrick Kirwin to create a low-water, no-lawn, deer-resistant garden that offers a beautiful example to neighbors trying to cut back on their own water use.


In this era of native-plant appreciation and, sometimes, rigidity, it’s worth noting that the garden is not strictly a native-plant garden. The Ogdens use many natives in their designs, but they are first and foremost plant lovers who use plants from all over the world. The key to using non-natives successfully, as Scott has explained, is to choose plants from climates that are similar to our own. Well-adapted plants add diversity, which is especially welcome in gardens overrun with deer (which often results in a severely restricted plant palette) and to those who crave a little variety in plant choice.


TexasDeb, a Rollingwood resident and blogger at Austin Agrodolce, alerted me to the new garden about a year ago and suggested I visit. Last week, when the bluebonnets were in full bloom, I stopped by and enjoyed a leisurely stroll through the spring-blooming garden. While still quite young, the garden is filling in quickly and should be showy this fall with ‘Pink Flamingos’ muhly and other grasses, salvias, lantana, mistflower, and beautyberry.


The garden harvests rainwater not just with cisterns connected to gutters but with earth-sculpting. A wide, shallow basin in front of the galvanized cistern collects excess water and holds it, giving it time to soak into the soil. Plants that appreciate a little extra water and can handle seasonal flooding are planted in the basin, like grasses, crinum lily, and Mexican summersweet (Clethra pringlei). Dry-loving plants are kept outside of the basin or on the fast-draining rim.


The entire garden is mulched with angular gravel, which wildflowers like poppy love as much as agaves.


Chopped limestone edging sets off the main gravel path, but for secondary paths the gravel flows sans edging from beds to paths, for a unified look. Plant density, subtle berming, and extra-wide paths help people see where they should be walking and keeps them out of the plants.


This seating spiral — a unique take on a council ring — is a cool feature.


Equal parts seating, garden architecture, and art, it’s constructed simply of large limestone blocks, with corners filled with cairns of stacked, flat stones. Five ‘Green Gem’ boxwood balls add evergreen rhythm around the perimeter.


A “lawn” of ‘Scott’s Turf’ sedge (Carex retroflexa), which you can find at Barton Springs Nursery, is filling in under the shade of a large live oak.


The sunny side was abloom, during my visit, with native and adapted wildflowers, which add fast-growing color amid slower but ultimately architectural plants like agave, sotol, yucca, prickly pear, and barrel cactus.


I think this is Agave salmiana, with gray globemallow and Texas bluebonnets.


‘Whale’s Tongue’ agave (A. ovatifolia) and bluebonnets — a pretty combo


Wildflower, cactus, and succulent tapestry


Blues, purples, and silvers keep the spring color scheme on the cool side.


Datura and…what is this purple-flowering perennial? Update: It’s Newe Ya’ar sage (Salvia officinalis x S. fruticosa). Thanks for the ID, Linda Lehmusvirta!

From the top of the steps up the hillside, you get a nice view of the sunny side of the garden. Yes, that’s the city hall building — a former residential house, from the looks of it.

Congratulations to the residents of Rollingwood for funding and otherwise supporting the creation of this beautiful water-saving garden. What a great example for other cities to follow.

Classical beauty with a modern edge in Sprout’s Rollingwood Garden


I’ve been fortunate this spring to visit a number of new-to-me gardens. One of my favorites is this one, the creation of talented landscape architect Jackson Broussard of Sprout. Located in the Rollingwood neighborhood, the garden is a refresh of an existing garden that, according to Jackson, had plenty of cottage color but not much structure or interest once the flowers faded.


To provide structure and year-round appeal, Jackson carved out space for a dining patio in the heart of the garden. Low limestone walls define the space and offer extra seating as well as a place to display potted plants (see top picture). In the center, a farmhouse table and chairs invite relaxation and al fresco dining. The space is roofed with an arbor of four Bradford pears espaliered to a metal frame — reminiscent of Deborah Hornickel’s Bradford pear arbor. Jackson explained that the ornamental pear’s flexible limbs and fast growth make it well suited to espalier.

The double line of trees, walls, and long table lead the eye straight to an overscaled terracotta urn elevated on a circular plinth and framed by a striking cluster of powder-blue Yucca rostrata. It’s a stunning composition.


The structure and openness of the dining patio — amid a lushly planted garden — draws the eye wherever you stand. Here’s the view from the back gate, looking across a tapestry-style shade garden.


And a little closer, with roses in the foreground


Those yuccas, though! They’re like blue fireworks exploding above blooming aloes and poppies. The brick wall at the end of the path separates the garden from the pool patio behind the house. The seclusion creates a secret-garden mood.


Entering the garden from the gate by the house, the urn is the focal point.


Throughout the flowering perennials and annuals, evergreens like blue nolina (Nolina nelsonii) add structure and beauty that doesn’t fade away in winter.

And looking the other direction

Flowering roses add romance and spring color.


Curving along the back of the garden, the path is edged with pink phlox and false foxglove penstemon (I think) Chinese foxglove (Rehmannia elata). A clipped boxwood in a terracotta pot makes a classical accent.

The main path bisects the garden, with the shade tapestry and pear-arbor patio on the left and the sunny flower garden on the right.


The shade garden is spectacular, with a lushness usually reserved for more-temperate climates. Red amaryllis blazes in the foreground.


Shades of green, with a pop of red, and a killer focal point


Dwarf Japanese maple, persicaria, and leopard plant make up the tapestry of foliage in the shade garden, with amaryllis sprinkled throughout, some in bud and some in flower.


The back gate offers a sneak peek of the garden inside.

My thanks to the owners and to Jackson Broussard of Sprout for allowing me to visit and share this beautiful garden with you!
