This is probably the paltriest bloom day I’ve had in a long time. A few months ago, when we started working on our new garden shed, I cut a lot of the plants back hard to get them out of the way while we’re working. I expected them to come back with the winter rains, but that was depending on it actually raining this winter. We’ll see if that eventually happens, but until then a lot of the plants are still dormant. Overall, though, the weather has been great for our project. Later today the window goes in; tomorrow we do the sheetrock. Then we’re mostly just waiting on the door. After that I’m going to stucco the exterior to match the house and do a stone floor. By early February it should look finished, though there’ll likely still be more finish work to do.

Between the construction and the time of year, the calendulas are the only plant that really makes a show of color in the garden. They’ve been kicked, stepped on, hit with two by fours, buried under stacks of bamboo, and they just spring right back up and keep blooming. The original seeds were blessed by Amma the Hugging Saint, apparently a powerful blessing.

Anita started looking after the veggie garden after the construction started. Not much happening in January.

The Chasmanthe is blooming well in our hell strip. I should appreciate them more than I do.

The Iochroma has some flowers up at the top of the plant. It seems able to bloom at any time of the year in our garden.

With all the sun we’ve been having lately, I thought there might be a lot of out of season blooms, but the Salvia ‘Green Carpet’ is the only one I would call truly out of season. There are a few token flowers on the Galvezia, the Sidalcea, and the Huechera maxima, but that’s happened in past years, too.

This little manzanita cluster has a berry, old flowers, and new flowers. I feel like this isn’t a good year for the manzanitas, with the lack of rain, but I don’t really know yet. This guy, A. ‘John Dourley,’ is doing pretty well considering he’s been covered in sawdust several times.

We have a few other things in bloom but nothing else of note. Mostly the garden is hunkered down, waiting for the construction to finish and the rains to come. Thanks to Carol for hosting Bloom Day. Check out MayDreamsGardens for lots of gardens showing off their flowers.

Last weekend I went to see the Drew School vertical garden by Patrick Blanc, the French botanist who started the current green wall craze. He designed a wall in San Francisco that was installed this past February . I was a little skeptical of the whole green wall thing, but then looking up at his wall — four stories high of California natives with over 100 species — my doubts evaporated. The whole thing absolutely overflows with enthusiasm for plants. Two big walls covered in natives, what’s not to love.

A pair of gardeners were doing maintenance while I was there. At first I was a little bummed to see this big orange cherry picker in front of the wall, but then I realized that it was a great opportunity to find out about the wall. I mean, I see this thing and I wonder how much does it cost, how will it age, how much maintenance does it need, and who will give me one for Christmas? Watching them work, I was impressed at how easy the maintenance actually seemed. Like any other gardeners, they cut the plants back with Felcos; they just let the green waste fall to the sidewalk and they barely even had to bend over to work. Progress was steady. It looked quite pleasant.

The plants are essentially growing hydroponically. The black flannel acts as the planting medium for the roots, and water mixed with nutrients drips down the wall, collects at the bottom and then recirculates. This is the first time anyone has ever tried something like this with California natives (he usually uses tropical plants), so the project was considered something of an experiment. Some species like Oxalis oregana or Mimulus cardinalis seem like reasonable candidates for a hydroponic wall, but some of the others like Artemisia tridentata and the Fremontodendron were a shock to me. It’s hard to tell from the photos, but up at the top there’s a Ribes sanguineum, a couple of bushy Mallows, and at least one Ceanothus.

The gardeners said they had done some replanting in September, but this was the first full maintenance pruning. They were cutting things back to do a one-year assessment of the planting and see how everything was growing. After a year of growth, some plants were starting to cover others. The Beach Strawberry was running all over the place, the Dudleyas were getting covered by other plants the same as they did in the Academy of Sciences green roof, the Lupines were short-lived, Penstemon heterophyllus looked like it was also going to be short-lived, but overall the plants were doing really well. The shrubs up top were growing exuberantly, maybe a little too exuberantly; the shade groundcovers down towards the bottom had the best year-round appearance. I found that in the places where the fabric showed between the plants, it didn’t bother me or diminish the effect.

Pretty healthy for a bunch of plants on the side of a building.

I definitely want to make it back in the spring when a lot of the plants have grown back in and are blooming. It really does have tremendous impact when you see it on the street.

This weekend I pulled out our summer veggies and started most of our winter plants. It was a little late to be taking things out; our basil was starting to brown from the cold, the green beans were being eaten by a pest, and the zucchini was still healthy but had slowed its production. (I had planned to wait until we finished our garden shed, but that project has gotten more ambitious and is taking longer than I expected. The shed will be very cool when it’s finished, but for now it’s just at that tantalizing phase where we can see what it will be like but can’t yet use it.) After five winters at this garden, everything this winter will be plants we’ve grown before — favas, snap peas, beat greens, chard, kale, broccoli, parsley, radishes. There’s less of it this year, as our veggie garden has been slowly turning into a fruit garden, with blueberries, huckleberries, currants, and strawberries now filling up the edges

The other change from past winters is the stone edging on three of the four beds. In August, I pulled out the old scrap wood edging I built five years ago and I replaced it with scrap stone from several recent projects. Some of the stone is a little small and raggedy on the backsides of the beds, but overall I had good stuff to work with and it was fun working with four different kinds of stone in one little area. I came up one stone short with the cabernet wall and I bought the two corner stones to use with the beige sandstone, but it was a near-perfect quantity with about eight of the little bluestone squares leftover and nothing else. The saw-finished sandstone is more contemporary than I would have chosen for our garden, but I really like it.

Without the zucchini it looks a little bare and and in need of more tidying, but the stone just makes it so much better.

This is one last thing after several posts about lawn alternatives and sort of a bleg. I’m quite taken with Nassella laevissima, a tussock grass from Chile, in a beautiful planting at the UC Botanical Garden. I’ve been to that garden a bunch of times this year, and that meadow always strikes me as just about the best thing in the entire garden. But I’ve never seen it growing anywhere else around here. I probably saw it when I was in Chile fifteen years ago; I remember lots of beautiful grasses like this and it’s listed on the plantlists for some of the parks I visited. But no one seems to grow it here; I haven’t seen it in any of the new sod mixes, on any of the availability lists, at any of the specialty grass nurseries, or in anyone’s garden. Even online all of the photos are of this one single planting at the UC. I asked a friend who works at the botanic garden and she says it has been there for years and always looks this great with very little maintenance. Also, she says it doesn’t reseed like its poorly behaved relative, Mexican Feather Grass. So I’m just curious about why no one else grows it here in California. If anyone does know anything about it, please let me know.

Carex pansa, Dune Sedge

We recently checked in on a garden in Walnut Creek that we helped design and install two years ago. There’s a fair bit going on in that garden, but one of the things I was most interested in seeing was the Carex pansa lawn that we planted. C. pansa is one of the main lawn alternatives that gets talked about these days. It was our first experience with it. So far, two years after planting, I’m pretty impressed.

A Box of Lawn

We planted it as 2″ plugs ordered from Greenlee Nursery (they have a great webpage for Carex Pansa). I’m not sure what I was expecting, but it was a surprise when some cardboard boxes showed up with the grasses stacked inside. I don’t remember how many, but it was somewhere around 2,000, and I ended up planting about half of them by myself. I had scheduled the planting on a Friday, but we got rained out and then I was too soft to make everyone come back to help me on the weekend. I averaged about one hundred per hour. Maintaining straight rows and regularly spacing seemed actually kind of hard.

April, 2010, six months after planting, not much new growth yet

July 2010, starting to spread with the warmer weather

A quirk of this lawn is that it is watered with sub-surface drip irrigation. We were nervous that the plugs might not get their roots out in time to find the water, but we planted in November and they sufficiently established themselves by summer. Some of the plugs grew in quicker than others, and I’m guessing that’s because they were closer to the emitters. You can plant the plugs at six inch, eight inch, or twelve inch spacing depending on your budget and how fast you want them to fill in. We did eight inch spacing. The irrigation is managed by one of the weather-satellite/internet-based controllers that do all the thinking for you, so I don’t know how much water it’s getting at this point. Less than a traditional lawn for sure.

October 2011, 2 years

Along with water usage, I wish I had a good cost comparison. The plugs cost about three times as much as sod, it was definitely more labor to install, and we had to weed it several times in the spring and summer. But now that it’s saving the cost or labor of mowing and using less water, it should be making a big comeback on the economic side of things. Also, because it was irrigated with drip irrigation, it qualified for a rebate from the water company. I have a few more photos below. (more…)

Indigofera heterantha, Indigo Bush

As part of the projects we’re doing in our garden, this weekend we took out our Indigofera heterantha. (The common name is Indigo Bush because one of the related species, I. tinctoria, is the historic source for indigo dye.) I’ve shown it in bloom day posts a few times. Kind of sad to see it go. Anita bought it on a whim five years ago to try it out, and we’ve liked it, though not quite so much that we’ve ever planted one for a client. It’s a good plant, with nice pea-family foliage and flowers, and it’s pretty much the best thing blooming in our garden this time of year. But it’s also the last plant to wake up in our garden in the spring and it gets a lot of dried-out twiggy stuff on the ends of its branches; people ask us if it’s dead unless we cut it back. I think people usually shear them to maintain a rounded form, but ours is shaded by our bamboo for part of the year so it has grown upright and leggy and we limbed it up to the shape of a very small tree. We liked it and would have kept it longer, but we needed to clear space to move our old garden shed. It was a choice between removing the Indigofera or the Dr. Hurd Manzanita, which isn’t much of choice at all. Sorry, Indigofera. Farewell.

There&#'s a shed in there

If you look closely at the photo above, you can see our old garden shed, hidden amongst the bamboo. We cut down the bamboo and then rolled the shed out of there. The poor Indigofera was blocking where we needed to move the shed, but it was the only casualty of the project so far, along with the bamboo which our garden can well afford. I’m not sure I’ve ever fully conveyed how much bamboo our garden has, but it’s a lot, like ‘open a restaurant for panda bears’ lot. It’s the defining feature of the garden, twenty foot high golden bamboo on all sides completely screening our yard from the neighbors. We did two loads like you see in the photo below, and that only scratched the surface.

Just part of what we took out

Town Mouse and Country Mouse have started posting photos of their gardens on the first of every month. Below is the dominant view of our garden at the moment, the site of our old shed waiting for the next phase of bamboo removal, the not-so-fun digging phase. I’m not sure if we’ll have a new garden shed in this view by the start of next month, but we should be pretty far along.
