Throughout the winter we get people asking us if their tree or shrub is still alive. Plants sometimes fool us people in the Bay Area when they drop their leaves, and the frosts of winter often cause tender evergreens to suddenly look dead, and then in the spring there is sometimes one plant in a garden that doesn’t leaf out when all the others do, making everyone wonder if it is still alive. It can be hard to tell. Last fall, I planted a Spiraea “Anthony Waterer” that my dad has prematurely declared dead twice already.

We have an easy method for diagnosis: Scratch the bark with a fingernail or blade. The branch should have a bit of green under the bark if the wood is still living, but it will be hard and gray if the wood is dead. Dead wood won’t come back to life, but if there is green wood, we just cut out the dead and wait.

There’s a saying in back-country first aid: No one is dead until they are warm and dead. The human body has the ability to go dormant in extreme cold, and not even doctors can tell the difference between death and extreme stasis; frozen people have occasionally revived after days without a detectable pulse. Plants have even greater dormancy and regenerative powers than humans, so we generally apply that same rule to plants, with June as the approximate plant equivalent of warm. No leafless plant is dead, until it is June, leafless, and dead.

The stoneworker’s artist-of-choice, Andy Goldsworthy, has a new installation in the Presidio. It’s pretty cool, a one-hundred foot tall spire made out of forty lashed-together Monterey Cypress logs, culled from aging, declining trees that needed to be cut down. After cutting them down, they lashed them together into the spire and planted new trees around it in the spots where they had cut down the old ones. The spire will eventually rot and have to come down, but by then the new trees will have grown up around it. 

From now until May 3, there’s also a small exhibition with some of the drawings for the project, some photos of the installation process, and a few small art pieces including this junior spire inside a closet of the exhibition building. 

The NY Times has an article with a nice photo of the spire. This video has some footage of Goldsworthy’s first log spire, the no-longer-existing Grizedale spire.

Arizona peach flagstone patio

Building patios is hard on the body. Too much bending, awkward lifting, and the wide spread of the stone amplifies the weight of the stone; building walls is much easier on your back. I feel like I could build walls until I’m sixty, but there must be a limited number of patios in my back. So a couple of months back I made a decision to build only 40 more flagstone patios in my life. That number is exactly as subjective as it sounds. Read the rest of this entry »

Sunset should have a description for Arizona flagstone: drought-tolerant, best in full sun, tolerates some shade, longer lived in well-draining soils, short-lived in zones that get hard frosts.

It’s from the Southwest, so it likes Southwestern conditions, same as the plants. The stones were all freebies leftover from a project where I was working for another designer who had ordered too much stone. To give the stone proper drainage, it’s best to lay the stone in decomposed granite and gravel, but at our house, a rental, we wanted to keep things cheap, so we laid our flagstone in dirt, and it has done okay for us. It settled more unevenly than it would in DG, several of the thinner flagstones cracked, and the stone didn’t hold its color, but the graying, mossy flagstone patio fits into the rustic aesthetic of our yard so we’re happy enough. Arizona flagstone tolerates shade and clay soil, it just doesn’t thrive in it.

We planted a few different groundcovers in the joints of our patio. The baby’s tears is looking the best these days, during the winter rains. It used to dry out during the summer, but this year we had some pots near it, so it got the water that drained out the bottom of the pots and managed to stay green all year. It’s probably our favorite groundcover for damp, mossy areas.

Here’s a photo of the patio in May. The baby’s tears is in the back behind the heuchera flowers.

Rock of Ages #1 by Edward Burtynsky

I got excited during the opening of the new James Bond. During the big car chase, a character said, “They’re heading for the quarry!” I’m into quarries and figured something really good was going to happen. After all, the best scene in the last Bond was the chase through the construction site. But Bond-in-the-quarry was a little disappointing: no great stone moments, no Indiana Jones boulders, nothing particularly quarry-specific. Bond drives really fast, dodges a lot machine gun fire, then shoots the driver of the other car and wins. Note to villains: machine guns don’t work against Bond. 

I occasionally come across links to webpages about former quarries. I’m going to try to keep some of them bookmarked here. We’ll see how many I add over time.

Bringing Down Marble from the Quarries in Carrara, 1911, John Singer Sargent

John Singer Sargent did a number of works at the quarry in Carrara. My favorite is above, a rare instance where I like an oil better than the watercolors. Others from his Carrara paintings and drawings can be seen here.

Canaletto’s The Stonemason’s Yard

I also like a quarry watercolor by Stewart White.

Other paintings include Old Quarry, Rockport by Henry Aiken Vincent, Quarry of the Chaise-Mre at Fountainbleau by Corot, The Sand Quarry by Guillaumin, Chou Quarry by Gauguin, a series at Bibemus Quarry by Cezanne, Bibemus Quarry was also painted by Andrea Masson. I can’t find Childe Hassam’s series at Rockport Quarry online, and I don’t particularly like The Quarry Pool, Folly Cove, Cape Ann.

The best quarry photographs, including ones from Carrara, are by Edward Burtynsky. Burtynsky’s website has a great gallery of quarry photos.

The best quarry scenes in film are the ones in Breaking Away. Garden State has a quarry scene too. I have mixed feelings about it.

Quarries and Beyond has the most info.

Quest has a writeup on some of the old quarries in the Bay Area.

Parc des Buttes Chaumont is probably the most famous park made from a former quarry.

Opus 40 by sculptor Harvey Fite, a quarry site turned into a massive dry stone sculpture. It’s currently falling down because he didn’t break his joints, but there are efforts to preserve it.

Robert Morris made an amphitheatre/scultpure from a gravel pit, Untitled (reclamation of Johnson Gravel Pit). Robert Smithson’s Broken Circle/Spiral Hill is in a former sand quarry in the Netherlands. IHilary Anne Frost -Kumpf has a webpage about reclamation projects which includes info on the Morris and Smithson pieces, Opus 40, and a Michael Heizer piece Effigy Tumuli.

Quarry Garden in Shanghai Botanical Garden, a former quarry turned into a park, won an ASLA award in 2012.

Reordering Old Quarry, a residential landscape on a former quarry, by Reed Hildebrand also won an ASLA award in 2012.

sustainable sites native garden case study

Sustainable Sites Initiative has a collection of case studies that illustrate green building practices. The most interesting to us is Garden/Garden:A Comparison in Santa Monica, where the city installed a traditional front yard lawn garden and a low-water, native, sustainable design garden on adjacent lots so that people could see the side by side comparison. 

The native garden cost about one third more to install, $16,700 vs. $12,400; that cost difference came from the installation of a DG walkway to replace the existing concrete walkway and installation of rain gutters and a stormwater infiltration pit.

The native garden used 77% less water, 283,981 gallons/year vs. 64,396 gallons/year.

The native garden generated 66% less green waste, 219 pounds/year vs. 647.5 pounds/year.

The house and yard of the traditional garden look like relics from the sixties. I sure wouldn’t want my front yard to look like that, so I salute the owners taking a hit for science.
