The UC moved a 100-year-old Julia Morgan building from campus up to the botanical garden. Apparently it was in the way of the latest Haas Business School expansion. There’s a video of the moving process here and an article about it at SF Gate with some nice photos. It’s a great little building. From the outside it’s not showy, but the interior makes you appreciate good architecture, with wonderful reveals in the woodwork, a great old brick fireplace, and windows overlooking the garden. I’ve liked Julia Morgan buildings all the way back to when I was kid with no interest in architecture.
The building sits quite nicely in the landscape when you consider that it was built for a different site and then adapted to a hillside. The garden has plans to use the building for events, including renting it out for weddings and parties, so this seems likely to be it’s final home.
The new plantings around the building have an interesting concept. Because the garden features plants of ‘documented wild origin’, there are very few cultivars in the garden — almost everything is a true species with records kept of the provenance and genetics of each plant — and yet a lot of cultivars have been selected from the garden’s plants. Roger Raiche, in particular, selected a ton of California natives that have become mainstays in the nursery trade, Roger’s Red Wild Grape and Ceanothus ‘Kurt Zadnick’ being just two that I know offhand. For the new planting around the building, the garden decided to make an exception to the ‘documented wild origin’ policy, and instead do the planting with California native cultivars introduced from the garden.
Landscape architect Ron Lutsko gave a pro-bono planting plan. It should turn out nice enough but I didn’t find it quite as interesting as I expected. It seemed a bit ho-hum, with some Manzanitas and Ceanothus against the building and much of the planting looking like his office just hatched a big area and labeled it ‘perennial mix’. I understand why plantings are so often done this way, why so few prominent LA’s place the plants themselves and instead just hand off the drawings to a contractor to implement, but it does seem like a missed opportunity for a planting in a botanical garden, especially when probably half the garden’s staff have horticulture degrees. But I don’t know the politics of the garden and how these things get decided, and I shouldn’t complain about someone’s pro-bono work. It will compliment the building nicely.
Much of the new planting will probably resemble this mix of natives near the entrance to the garden, a nice enough green patch and very pretty when things are blooming. I’ll try to take some pictures of the new planting after it has had a few years to grow in. I’d also like to find a plant list to see which cultivars are from the garden.
I wandered around the rest of the garden and in particular the South African section which was looking terrific. Lots of bold colors. By April the native section will rival it, but in February it is the unquestioned star of the garden.
A new plant for me was this Leucadendron eucalyptifolium. Apparently this is only a five or six year old specimen to reach this size, twelve or fifteen feet tall. I’ve never seen it available in the trade, so perhaps a selection should be made; it could be planted years from now when the next building gets sent up from campus.
Requests for Mexican Feather Grass are one of the constants of doing landscapes in the Bay Area. I don’t blame anyone for wanting it. It’s stunningly beautiful, especially at the end of the day in the golden hour. But of course it’s also highly invasive. Planting it in your yard essentially means you are planting it in your neighbors’ yards as well. I try not to plant it, and in fact the only time I have planted it in recent years was for a parking strip in an urban part of Berkeley. I warned the client that it would spread to the neighbors’ yards and he pointed out that the neighbors were already growing it. It was hard to argue with that. But, otherwise, when clients request it I try to find an alternative.
This planting is one of my attempts. Instead of a gold-colored grass — PlantRight has a list with several alternatives that are fine plants but not really as graceful or beautiful — I went with the more cream-colored bloom of Pennisetum orientale (a Pennisetum that doesn’t reseed) and a background of Lomandra ‘Breeze’ to keep things looking green in the winter. I had the idea that the two of them together might combine into the equivalent of Mexican Feather Grass. I think they do end up having a little of that vibe. I should be able to get a better photo later in the year when some of the other plants are blooming and when the shrubs have grown a bit more, but this is pretty good for a January photo. Some ‘before’ photos are below. Read the rest of this entry »
I’ve been meaning to get back on my bloom day horse this year. This month’s offering is pretty light, but better than last month when there was very little going on. We have a few bulbs in bloom, the species tulips (Tulipa saxatilis) probably being the highlight.
Ipheion uniflorum (Spring Star Flower) is also blooming. I’ve been happy with how they well they’ve come back each year. They’re a relative of our native Brodiea, another bulb that has done well in the garden.
Several Hellebores are blooming. This dark one is my favorite.
The Sidalcea grown from seed are starting to bloom. We also have a native cultivar of Sidalcea, but it hasn’t started budding yet.
There’s one Solanum umbelliferum ‘Indian’s Grey’ in the garden. It has more flowers than foliage at the moment. This is its second year in the garden, so I haven’t figured out if that is normal for it.
Our Ribes sanguineum used to be ‘White Icicle’ but it has fully reverted to the regular pinkish form. It’s also more upright than it used to be. It was a passalong plant, so I don’t mind. It’s the only ‘White Icicle’ that I’ve seen revert. This winter doesn’t seem to have been cold enough to knock the old leaves off the branches.
We have a few other things blooming. Salvia ‘Green Carpet’ has some flowers. Geranium ‘Bill Wallis’ is starting up. There are a couple of Freesias and a Daffodil in bloom. Woodland Strawberry, Galvezia, a couple of the Blueberries, and Arctostaphylos ‘Dr Hurd’ each have a few token flowers. The Ninebark is the first of the deciduous plants to begin leafing out; its new green leaves are always as pretty as a flower.
For more bloom day posts, check out May Dreams Gardens. Carol says this is the ninth year of bloom day. Really impressive. I’ve always felt that bloom day was the single best thing in the garden blog world. A salute to Carol, and my thanks for keeping it going so long.
‘For the first time since 1850, San Francisco will log .00 of rain for the month… The previous record low rainfall was 0.06 inches set just last year. In January 2013, 0.49 inches of rain fell on San Francisco… The past three Januaries in San Francisco are among the five driest on record. This has brought the average for the past ten years down to 3.03 inches, dramatically lower than the 30-year normal of 4.55 inches.’

As a rule of thumb, the evapotranspiration rate doubles in February and then doubles again in March, so January isn’t a real critical month in terms of rainfall for the garden. Factors like day length, dew, winter dormancy, and low plant metabolism keep the plant water needs low, even when the weather forgets that it’s the rainy season.
But I don’t really know the effect of six weeks without water in the heart of our rainy season. Some of our clients turned their irrigation on, some left it off. A couple of gardens are weather-satellite controlled, another has a low-budget rain sensor; who knows how often those systems ran. My parents turned their irrigation back on to full summertime levels (I guess they didn’t believe me about the evapotranspiration), and the elderly tenant of a friend never turned the irrigation off at all, not even during the heavy rains in December. And I’ve realized, looking at some of these gardens, I can’t really tell the difference. I don’t see signs of drought stress in the unwatered gardens and I don’t see signs of over-watering in the over-irrigated ones. If I can’t see a difference, it’s probably best to save the water, but who knows, maybe the effects will start to show later in the year. I’m just glad it’s raining.
One native plant I haven’t always appreciated is Erigeron glaucus. It’s a nice enough plant — tough, low-water, good habitat value, long bloom period, showy during peak bloom — but the odd yellow in its center clashes with the purer yellows I like — Coreopsis ‘Moonbeam’, Achillea ‘Moonshine’, daffodils — and I’ve also never been totally happy with how it combines with a lot of the purplish bloomers that I tend to use. I have a dozen of them in my garden, but I only have them because I bought them on impulse for a project and then decided they clashed with the other plants. I brought them home and eventually planted them because I didn’t have anywhere else to put them; they look okay but I’ve never been particularly excited about them.
I really like how they work in this planting, however. The cultivar is ‘Wayne Roderick’, which has more of a lavender tinge to the petals than the pinkish ‘Cape Sebastian’ in my garden. More than that, though, I like them because the planting around them is primarily grasses — Sesleria ‘Greenlee’s Hybrid’, Festuca idahoensis ‘Tomales Bay’, and Lomandra ‘Breeze’ — and a patch of Delosperma, so there aren’t a lot of other colors for the yellow to clash with. And even though there aren’t many other things to bloom in that part of the planting, they bloom heavily enough and continuously enough to carry the flower burden; it’s December and they haven’t been cut back once this year, but they still have flowers. The focus of the photo above is the Sesleria in front of them, but the flowers in the background do a lot to add interest and give it a meadowy look, and all those old stems waiting to be deadheaded speak to what they looked like earlier this year. Obviously I’ll be able to get a better photo in the spring, but this is pretty good for mid-December without any maintenance, and it’s nice to find myself coming around to a native plant I hadn’t previously embraced.
There is a garden somewhere inside this blog, though I haven’t posted about it much this year. It’s been a transition year for the garden. I’ve been changing around some of the plantings and I’ve upgraded some of the materials with leftover stone from the garden show and some of my installation projects. As a result, the garden has been more of a construction zone than I would like; little piles of leftover stone are probably its distinguishing characteristic. I only work on it a few hours here and there, so every project takes longer than I’d like, but I’m starting to make progress on it all.
The front path is one project that is almost completed. When we moved to this house, the front walkway was paved only with broken concrete set in dirt, so the stone is a big upgrade. Besides looking better, it’s easier to see at night and makes a much smoother and tidier walking surface, even when it needs to be swept. There are five kinds of stone in it — a large piece of bluestone at the top of the stairs, a large piece of sandstone, a slate-y wall stone, three slices of limestone from a paver that broke during the garden show, and quite a bit of basalt from the scrap pile at the stoneyard. The three hexagonal pieces are the best spot, slices from a basalt column that weren’t good enough to be sold as pricey stepping stones. I like the scuff marks from the saw.
A few of the small pieces of wallstone are place holders and will probably be swapped out at some point when larger pieces of stone come home with me. One thing I’ve learned is that, when it comes to my garden, stone happens; if I’m patient about a stone that I don’t like, an alternative will eventually come home with me to take its place.
I haven’t quite brought the path all the way to the garden gate. I’m undecided what to do in that last section. Part of me wants to do a mosaic, part of me wants to lay something less ambitious and be done. We’ll see, I’ll probably lay something temporary and if I want to change it at a future date I can.
I added a bit of edging to one of the inner garden beds. Again I’m undecided whether to continue the line along the entire bed. The flagstone path was leftover from a job I did for another designer seven years ago. It has served well enough, but I can look at it and see that it was stone I rejected from a professional installation. Upgrading the outer path made me want to redo this inner path, the kind of thinking that causes the garden to always resemble a construction site.
Another recent project is the replacement of the raised bed for the graywater from our washing machine. I built it with scrap wood and filled it with Canna and Fuchsia. It looked fine as long as you couldn’t see my terrible carpentry, but the wood eventually started to rot out, the fuchsia got crowded out by a nearby spicebush, and we got tired of the Canna. I redid the bed with basalt pieces that I used in the garden show. I love that the capstone is a single nine-foot-long piece. The new plants are all natives — Juncus patens, Yerba mansa (Anemopsis californica), Scarlet Monkey Flower (Mimulus cardinalis), and an Adiantium that I’m hoping will do well in the face of the raised bed.
Water comes from the washer and drains out from holes drilled in the pipe at intervals. The back wall of bed, out of sight tucked under the porch, is rubble that is dry-stacked with a water-proof liner on the inside of the bed to keep the water from seeping out before the roots and the soil bacteria have a chance at it.
Above is what it looked like six years ago. We’ll see how the new planting does. The plants are divisions or transplants from other parts of the garden, but things should fill in quickly, hiding the pipe and probably some of the stone; I think the scarlet monkeys will like the graywater, but they are an experiment. At the moment I like that the stone isn’t covered by plants, and I like the contrast between the polished piece of basalt and all of the saw-finished pieces. I might end up polishing them all to match; there’s something compelling about a graywater bed made with shiny, polished stone. We’ll see. Like any new project or planting, it has me looking forward to what it will look like in spring.
