A must-read for gardeners and wannabes: The Layered Garden

In my spare time, I’ve been devouring the The Layered Garden, by David Culp with Adam Levine.  The title jumped out at me when I got the latest email promotion from Timber Press, so they sent me a copy and I’m reviewing it.

As part of their fall promotion, Timber Press is giving away an amazing deal – 5 books, a tote bag and a signed print by Brooke Weeber.  Just go to Timber Press to enter and win. 

All the books look great, but an entire book on layering in the garden, the history of David Culp’s garden and then, the icing on the cake, Rob Cardillo’s photographs — well, I just couldn’t resist.  And I’m glad I didn’t.

The Layered Garden is an inspiration for experienced and new gardeners alike.  Filled to the brim with beautiful photographs — especially long shots with detailed design components — it offers a full pallet of ideas.

The book chronicles the creation of the gardens of David Culp and his partner, Michael Alderfer, at Brandywine Cottage in Pennsylvania.  Purchased in 1990, the cottage itself was built in the 1790’s and the original farmland subdivided into 2-acre lots.

Both a garden designer and a plant collector, Culp writes, “I express myself in two distinct ways: as a plantsman who enjoys collecting specimens…and as a designer who enjoys playing with plants to achieve a desired effect.”

The first section of the book weaves the tale of each of the distinct gardens and how they came to be so lush and full.  The gardens are designed to be layered in many ways — layers of sizes and textures and colors and layers that peak at different times of year, allowing different waves of bloom.  Other elements like pots and antique stone troughs add interest and more layers, and they plant them with seasonal accents and plant displays.

The garden includes layers of tall plants and man-made elements to provide vertical interest in the garden. 

Then I got to the third chapter of the book, “Signature Plants Through the Seasons,” where he admits, “Hello, my name is David, and I am addicted to plants.”  That really spoke to me!  Full of beautiful photos and detailed information about the focal point plants of each season, his collector’s passion is evident here.

He closes with a list of his favorite garden books, which I’ll definitely be checking out, too.

Layers and layers of plants and colors and textures — gardens waves of blooms that peak throughout the year — that’s what I want in my garden.  And I’ll be going back to this beautiful book time and time again for inspiration and ideas.

Hues of green evoke serenity in Austin garden on Open Days tour

The Yvonne Tocquigny and Tom Fornoff garden, featured on this weekend’s Garden Conservancy’s Open Days Tour,  evokes a sense of serenity as you stroll through its simple combinations of grasses, vines and water features.

Simple yet strategic views draw you into the garden with a series of gates, paths and courtyards.

The beautiful gray-green hues of Dichondra, Silver Ponyfoot, create a gentle contrast for the other lime and grass-greens of the garden.

The entry courtyard includes this simple, Zen-like water feature, surrounded by strappy crinum leaves and fine gravel.

The garden was full of berkley sedge – providing a caress of beautiful texture throughout the vignettes.

 More contrasts with the berkley sedge – younger, smaller plants, and the silver ponyfoot.

The garden is also full of a variety of trellises – like this metal and wood one, set out 8-10 inches from the wall.  It supports the rosebush, but it’s also an artistic focal point on its own.

 Beautiful lanterns were mounted right onto the wood and metal trellis.

 More contrasts surround this inviting bench — both in textures and in hues of green, and a Japanese Maple thrown in for a pop of color.

 The water feature in the back courtyard has an old-world charm, and is surrounded by simple plantings of t=ferns and irises and papyrus.  Ferns also dot the decomposed granite pathway, growing up out of the ground at our feet.

Another trellis creates a wall of plant art to add to the sculpture of the courtyard.

Peering into the fountain through the fronds of the papyrus creates another combination of contrasting hues of green.
This was a beautiful and intentional garden – complex, even in its simplicity – a peaceful place to while away the hours. 

Agave afficionado’s garden delights on tour…

Today I joined my garden blogging friends Pam Penick, of Digging, Cat Jones, of The Whimsical Gardener, Jeanne McWeeney of Dig, Grow, Compost, Blog, and Shirley Fox of Rock, Oak, Deer, for the Garden Conservancy’s Open Days tour.

It was a great morning – a little foggy early on, but very comfortable for garden gawking.  We toured six wonderful Austin gardens — all of them true gardener’s gardens — full of creative and personal touches.  I met most of the gardeners and hosts and enjoyed hearing about the evolution of the gardens.

 Carved into rocky ledges, Jeff Pavlat’s garden was a southwest/agave afficionado’s dream come true.  Every imaginable combination of agave, aloe, yucca and cactus bedazzled us.

With our changing climate here in Central Texas, these plants are proving to be great additions to gardens that are in as much transition as the weather.

 Layers of limestone steps and retaining walls combined with the natural escarpment to lead visitors down the slopes.  Artistic touches complemented many of the vignettes and combinations.

 There were even agaves where there were no agaves.

 Some of the focal points were whimsical, and others were inspirational.

 Pots were also used to add height and interest to plant combinations.

 Looking down into a stream and koi pond, the sound of water beckons you for a closer look.

 The welcome committee was still hanging around from Wednesday night’s festivities.

 Many of the small specimens were scattered about in beautiful, textured pottery.

 And, above all else, his is a collector’s garden.  Plants fill every inch of the greenhouse.  I have no idea where the big pots will go in the winter!

 A few critters were keeping an eye on us as we wandered through the garden.

 This one was easily the creepiest.

There were several varieties I vowed to find and add to my garden, especially this yucca gloriosa “tiny star.”

I thoroughly enjoyed this drought-tolerant and creative garden with all of its texture, stone and sculptural plants.

Sonoran’s saguaro cactus is a gem of the desert…

Amazing, isn’t it?

This is the saguaro cactus, Carnegiea gigantea, one of the most spectacular sights on my trip last week to the Garden Writers Annual Symposium in Tucson, Arizona.

The saguaro only grows in the Sonoran Desert, and it doesn’t do that very fast.  Saguaros only grow between 1 to 1-1/2 inches in their first 8 years, according to information published by the Saguaro National Park.

Our highly entertaining breakfast speaker, Peter Gierlach, former nurseryman, country singer and radio show host of “Growing Native with Petey Mesquitey,” told us that saguaro can be as old as 75 years old before they grow their first branch.  In drier areas, it can take up to 100 years to grow a branch.

Saguaras begin to bloom at about 35 and can live to be 175 to 200 years old.  They can get 50 feet tall and weigh as much as 6 tons.  (As my husband said to me, “you wouldn’t want that to fall on you!”)

According to the Saguaro National Park, “The roots of the saguaro grow in  a radial fashion, several inches under the ground.  During a heavy rain, a saguaro will absorb as much water as its root system allows.  To accomodate this potentially large influx of water, the pleats (of the saguaro) expand like an accordion.  Conversely, when the desert is dry, the saguaro uses its stored water and the pleats contract.”

Sometimes they grow in strange shapes, like this one intimately entwined with a tree at the Tucson Botanical Gardens.

This unique and creative metal art pays homage to the saguaro and its stature in the desert.

Wonder how old this guy is?  I thought these statuesque cacti were phenomenal when I arrived in Tucson.  When I learned their amazing history and story, I was even more impressed.

I am in awe of the will and ability of plants to adapt and grow in the harshest of conditions and against all odds. 

I suppose that’s why I garden…I appreciate the gift of being able to be a part of something so much greater than me.

Beautiful, xeric plants in the Sonoran Desert Landscape

Against the backdrop of the rugged Santa Catalina Mountains, tough, structural plants dot the landscape of the Sonoran Desert.

The Garden Writers Association Symposium Tucson, Arizona, included several days of tours of local gardens — an excellent introduction to the unique beauty of the desert.

 This is the view from the lobby of the La Paloma Resort where the symposium was held.

 Cacti, yuccas,  hardy woody perennials and trees thrive in the desert, where the temperatures soar into the 100s throughout the summer, yet also dip below freezing in winter.

 These cool, columnar Mexican Fencepost cacti (Pachycereus marginatus) bring height to the flat desert expanse.

 This desert garden was full of nooks and crannies filled with smaller species of cacti and aloes.  With approximately 2,500 different species of cacti, and about 400 different kinds of aloes, there are plenty from which to choose.

 Pots and other garden art and decor provided strong bursts of color in many of the desert gardens we toured.

 This citrus grove at the Benedictine Order of the Sisters of Adoration was lush with fruit.  The trunks are painted white to help cool the trees.

There were some more tropical plants — like these palms — throughout the desert, though clearly they require much more water to survive the harsh climate.

The light on the mountains at dawn and dusk was stunning. Inspiring hues of coral and lavender wash over the horizon, enveloping the harsh landscape in a robe of gauzy color.

Fall color in the Central Texas garden

The fall color in my garden this week isn’t from autumnal leaves on trees, it’s from a nice 1.5 inch rain last week and a few days and nights of cooler temperatures.

These zinnias have a whole fresh set of flowers.

All the perennials shrubs and wildflowers are flush with blooms.  Not just fall colors – all colors.

The firecracker gomphrena I planted just a month ago is spreading and has made the transplant with flying colors.

I guess the change of seasons is making them happy and giving them some relief.

These wildflowers just popped up in my cutting garden.  They reseeded from somewhere into a mass clump of perky yellow blooms.

My carefree beauty rose is dotted with pretty pink blooms and the deep purple indigo spires make a lovely contrast.


I was surprised to find the Japanese quince in bloom – it must have happened over night when I wasn’t paying attention.

The lackluster purple hyacinth bean vine, which has struggled all summer long – is finally showing off.

The change of seasons makes me happy, too.
