Cornerstone Sonoma showcases conceptual gardens in scenic wine country


It wasn’t easy, but I finally visited the gardens at Cornerstone Sonoma in Northern California, which have been on my bucket list for years. Due to my own poor planning, I first missed them after the San Francisco Garden Bloggers Fling, when I rented a car to explore up to Stinson Beach but inexplicably forgot to push on to Cornerstone. Doh!


Determined not to repeat that mistake, I planned a visit to Cornerstone during a family road trip from San Francisco to Portland earlier this month. We arrived on a beautiful, sunny day in time for lunch and then poked around in the market’s charming shops along olive-lined lanes. As the midday heat eased, I headed eagerly to the gardens — where I learned to my dismay that they were closing in 5 minutes for a wedding! As we were escorted out by staff, I watched the bride, adorable flower children, and elegantly dressed guests heading into the gardens and glowered.

Foiled? Not hardly! The next day, while my husband and daughter went zip-lining among coastal redwoods, I drove an hour back to Cornerstone for a quick visit before my hour-long return trip to pick up my family. Was it worth all that trouble? Yes! Let me show you what it’s all about.

Mediterranean Meadow by John Greenlee


Cornerstone’s gardens consist of 9 small conceptual installations created by landscape architects and designers. Each plays off a particular theme, idea, or mood. Inspired by the International Garden Festival at Chaumont-Sur-Loire (also now on my bucket list), the Cornerstone gardens were designed to be temporary and originally numbered 20. However, to accommodate the relocation of Sunset’s test gardens in 2016, they were whittled down to the 9 that remain today.


Ornamental grass expert John Greenlee designed Mediterranean Meadow, a billowy meadowscape accented by two striking sculptures: an openwork steel sphere by Ivan McLean, which allows glimpses of the swaying grasses and golden hills beyond…


…and a stacked-stone ovoid with bands of terracotta and white.


In the distance you see a tall steel mobile sculpture…


Time Killer by Diego Harris, which is currently for sale if you have a large space in need of a special something.


Peeking through a window in its steel base, I spotted another artful installation…


Daisy Border by Ken Smith. Cornerstone’s website explains:

“Composed of classic daisy pinwheels — a common garden decoration on American lawns — the border is at once artificial and natural. Made of plastic, it nevertheless registers sun, rain, and wind.”


I like the contrast between the colorful, toylike pinwheels and the muscular agaves and tawny grasses in the next garden.

Garden of Contrast by James Van Sweden and Sheila Brady


Designed by the late James Van Sweden and by Sheila Brady, Garden of Contrast is maybe the most famous of the Cornerstone gardens. I was happy to see this one! Toothy green Agave salmiana reach up to touch the dusty-green leaves of olive trees, while tawny Mexican feathergrass sways in the breeze below. Three species of plants, all of which grow in Central Texas, planted to perfection!


As Cornerstone describes it, “This design offers a new paradigm for the American Garden. The garden’s ground plane, a plant tapestry[,] combines texture and form, color and scent, while a canopy of olive trees adds a third dimension that changes in color and opacity as the seasons advance.”


In springtime, wine-colored drumstick alliums and orange California poppies thread through the grasses and agaves, adding sparks of seasonal color. I’d love to see that.


I couldn’t get enough of the contrast between muscular, stiff-leaved, saw-toothed agaves and feathery, pliable, strokable grasses. Actually I stroked the agaves too.


This agave is a monster at over 6 feet tall. Behind it, a diagonal line of rosemary bisects the garden, separating the sunny, grassy side from the olive-shaded, woodsy side.


Under the olives rests a huge steel-and-stone sphere, also by Ivan McLean, who writes:

“Noyo cobbles are the name of locally, Sonoma County area, found stones, 4″ to 8″ or so in size. It took 2 yards to fill this 60″ sphere, about 6,ooo pounds. It’s placed in a garden whose theme is ‘contrasts’, so you have the sphere made from squares and rectangles filled with round stones and a very heavy sculpture looking very light, at least that was the idea.”

In the Air by Conway Cheng Chang


I imagine plenty of engagement photos have been taken in the romantic and heart-adorned In the Air garden, designed by Conway Cheng Chang. Rebar arches help vines clamber over billowy, sedge-lined paths on one side.


On the other, a geometric arbor supports a cloud of white roses, and interlocking steel hearts playfully divide the garden in two.


Hearts and sedge


Love must be in the air.


As Cornerstone describes it:

In the Air intends to be playful and critical, spontaneous and composed. Air penetrates and circulates through all living organisms. It fills the in-between spaces and supports human life and emotions. The garden was created to reveal the form of air and in doing so help us understand and appreciate it.”


Purple clematis


And another purple clematis

Small Tribute to Immigrant Workers by Mario Schjetnan


A memorial to Mexican agricultural workers, Small Tribute to Immigrant Workers is the creation of Mario Schjetnan.


A maze of walls — red-painted plywood, corrugated steel, and rock-filled gabion — seems to reluctantly allow entry, each with photos and text about the dangers faced by migrants desperate to cross the border to find work.


Cuidado


A simple shrine hangs on a gabion wall, offering a place for prayers.


On the other side of the wall lie plots of edibles symbolizing the agricultural fields of California.


Artichokes

Eucalyptus Soliloquy by Walter Hood and Alma Du Solier


Towering eucalyptus trees line the roads in Sonoma, and Eucalyptus Soliloquy pays tribute to them. A gabion wall stuffed with eucalyptus leaf litter and a trellis screen of pinned eucalyptus leaves line a long path toward a view of a pond.


Cornerstone says, “The Sonoma landscape features eucalyptus windbreaks that divide field and vineyard. Eucalyptus Soliloquy is a conversation between distant groves and a built landscape of borrowed trees, orphan leaves, branches and seeds.”

Rise by Roger Raiche and David McCrory


Rise, designed by Roger Raiche and David McCrory, is one of my favorite gardens at Cornerstone. Its iconic steel culvert tunnel makes a playful path through the garden and seems to shrink you, Wonderland-style, to childlike dimensions as you pass through.


See what I mean? Cornerstone says:

“Rise is a celebration of color, texture, diversity, light, space and life. The plantings and landform, modeled on a natural landscape, are exaggerated to enhance the sense of separation from reality. Likewise the pipe exaggerates the sense of transition from one world into another.”


Walking through, you get a porthole view of a neighboring vineyard.


But the garden itself transports you to a tropicalesque jungle of dramatic foliage.


Sizzling! Later, Loree Bohl of Danger Garden asked me if I’d seen the Marcia Donahue garden at Cornerstone. I immediately knew she was referring to this distinctive garden.


Donahue’s artwork adorns the garden, like this tree necklace and some of her ceramic bamboo sculptures (previous photo).


More of her bamboo, at left of the tunnel.


Flowering fuchsia adds its own bright adornment, like dangling earrings.


Rise overlooks a large rectangular pond that stretches invitingly behind several of the gardens.


As you approach, hedges frame a view of the pond and ornamental grasses that overhang the far side.


Waterlily circles seem to skip across the water, echoing the rhythm of the tall grasses.


Beyond that, rows of grapevines establish their own rhythm, leading the eye to distant hills.

Bai Yun (White Cloud) by Andy Cao and Xavier Perrot


Bai Yun (White Cloud) is hard to photograph but absolutely mesmerizing in person. Fluffy clouds of wire mesh, suspended by metal posts, drip with hundreds of raindrop-like crystals over a desertscape of prickly pear and white dunes. Shadows are surely an intentional part of the design as well.


Such creativity!


You can’t help musing about drought, the preciousness of water, and gratitude for rain when you look at it.

Serenity Garden by Yoji Sasaki


Along a straight main path, narrow paving strips extend on either side into a green lawn in Serenity Garden. Cornerstone says, “Each element in this garden has been carefully selected for its effect, particularly of its ability to point to or register the ever-changing aspects of nature — shadows, wind, borrowed scenery and material texture.”


I wasn’t moved by this garden, but I did stop to appreciate the rough bark of the pine trees along the back hedge.

Birch Bosque


On the other hand, I loved this bosque of birches in the garden next door. I have a thing for bosques. I find the simple geometry of tree trunks, open space, and (usually) a hedge enclosure to be very soothing.


This garden lacked signage, and it’s not included in Cornerstone’s list of gardens. A little online sleuthing told me that it was formerly a garden by Topher Delaney called Garden Play. The original blue-striped wall and rope balls no longer exist, and an enclosing hedge now frames a view of a vineyard (previous photo).


That settles it: I am going to have a bosque of my own one day. But what kind of tree, I wonder?

Pollinator Garden


Another garden not listed on Cornerstone’s website, as of this writing, is a brand-new space that I believe was labeled as a pollinator garden.


A barn-like structure (wedding venue?) with a central hallway frames it nicely.


Bright with coneflowers, salvias and more, it’s sure to be a hit with insects, birds, and people.

Children’s Garden by MIG Incorporated


The last Cornerstone garden is a children’s garden by MIG. I was struck by the fact that this kids’ space is largely organized around a mini vineyard. Starting ’em young out in wine country!


A few colorful playhouses and birdhouses on tall poles add a little kid flavor.


But really, this space is all about the grapes. Which is an appropriate way to end a post about a garden in Sonoma.

  1. After seeing so many different gardens the Serenity garden would be soothing. A calm space to rest and think about all you saw. I like the bosque too. The white trunks of these trees are a nice contrast of the dark hedge. I could see some large blue balls resting under those trees. I had never heard of this place. Thanks for taking us there.

  2. Laura Munoz says:

    Thank you, Pam. Many of the Cornerstone Sonoma gardens grabbed and held my attention. ‘Rise’ spoke to me. I’m not sure what it is about this garden that pulls me in, but it does. I also like the round sculpture with cobbles in the sphere composed of squares & rectangles. Very cool!

  3. Wow, Pam what an amazing place. Now it’s on my bucket list. I hope you had a good time revisiting the West Coast – it sure looks like you did. There seems to be something to take away in each of these well thought out spaces. Thanks for the tour.

    Nice write-up Pam. I was happy when Sunset announced their move to Cornerstone because there had been not much new going on there for a few years and I was fearful for it’s future.Several of the former gardens were merged into what is a large event space walled off from the rest of the facility. I think this along with the barn are used frequently for weddings and corporate events.I’m glad you had enough flexibility in your schedule to make it there after being shooed out ! I haven’t been over there for months so it was great to see what they’ve done with that lawn area near the barn .

    • Pam/Digging says:

      Thanks for sharing, KS. I was a little sad when I realized that many of the original gardens were removed, but I couldn’t complain once I saw the gorgeous Sunset gardens in their place. And after all, these were meant to be temporary installations. Hopefully Sunset’s presence will continue to revitalize the whole garden area. —Pam

  5. Evan says:

    So glad you were able to backtrack to see these gardens and give us a tour! I’ll have to add this to my bucket list, as well. I love the Contrast garden, but the jungle-like Rise is my favorite.

  6. I’m happy to see some of my favorites remain. Did I really say “Marcia Donahue designed?”… if so I didn’t accurately frame my question. I was just hoping the garden that contained her work was still there, and I’m happy to see that it is.

    • Pam/Digging says:

      Loree, I think it was my misunderstanding, actually. You said Marcia Donahue garden, and I asked if it was the one with the culvert pipe and her sculptures, and you said yes. Sorry, I didn’t mean to imply that you thought she designed the whole garden. I’ll fix that. Anyway, that one was my of my favorites, along with Garden of Contrast and White Cloud! —Pam

  7. Pam – I can see why Cornerstone Sonoma was on your bucket list! It looks amazing and appears to be worth the hour drive back to see it!

  8. Alison says:

    So many “Big Idea” spaces, and then all that color from the Pollinator Garden! I’ve seen photos of that garden with the feather grass and Agaves, and never knew where it was. Love it. Looking forward to your post on the new Sunset space.

  9. Susie says:

    Well, this is fascinating. Glad you were able to check Cornerstone off your bucket list Pam.

    • Pam/Digging says:

      Me too, Susie. Although I never really check a good garden off my bucket list because I’m always excited to go back and see it again. A garden is always changing, and you can never visit exactly the same one twice. —Pam

  10. Pat Webster says:

    Getting to Cornerstone is one of my travel goals but this post was almost as good as a visit. Like others, I particularly liked White Cloud and Rise gave me an idea for a project I’m working on now. Eucalyptus Soliloquy was so evocative of what I think of as California desert and I liked that evocation. The Tribute to Migrant Workers and Birch Bosque reminded me of gardens I saw at Chaumont about a dozen or so years ago. The bosque there was designed by an American firm (wish I remembered which one) and made a point about over-crowding: the space was divided into sections, with one tree in the first section, two trees in the next, then four, eight, sixteen. Since each section was the same size, the point was very clear.

    I’m fascinated by the difference in ‘feel’ between the gardens selected for Cornerstone, Chaumont and Metis. Each jury selects according to its own criteria, and those may differ greatly. But more than anything, I sensed a sort of national flavour dominating each — quite appropriately, I’d say

    Really glad you covered this festival, Pam.

    • Pam/Digging says:

      Thanks for your thoughtful comment, Pat. I was especially interested to hear about the “overcrowded” bosque garden you’d seen. This was my first conceptual garden experience, I think, and I was fascinated. I’d love to see other ones, and I especially enjoyed your recent post about the one in Metis, Quebec. —Pam
