Flowers of Paradise

Happy Solstice! (9:47 AM for Berkeley, CA.) Here is the last of my photos from the botanic garden, a collection of manzanita photos. I tried to estimate how many of the manzanita varieties in the garden were blooming, and decided about one fifth or one quarter. If I were Mr. Manzanita I would declare that manzanita season has begun.

Paradise with Moss Rocks

But, sadly, I am not Mr. Manzanita. That name belongs to one of the staff at Tilden who, rather tongue in cheek-ly, wears a sign with that title during the plant sale every spring and answers all the questions about all the different manzanitas for sale. I had a question, ‘Which one is the best?’ Well, manzanitas cover quite a range, from ground covers to trees, all with their own subtle merits and attributes, and you generally need to know the site conditions before you can choose the right manzanita, so it’s rather ridiculous to ask someone to just pick one and say, ‘This is the best one.’ But I asked Mr. Manzanita to do that, to choose his favorite, all-purpose, reliable, not-too-fussy-about-soil, not-too-fussy-about-water, interesting, consistently beautiful, generic-recommendation manzanita. And he humored me and made a choice, choosing ‘Paradise,’ an A. pajaroensis selection introduced by, not too surprisingly, the botanic garden at Tilden.

Arctostaphylos pajaroensis Paradise

There are several different specimens in the garden, all in bloom now, generally growing to about shoulder height, wider than tall, with an interesting zigzag branching pattern. Brad at RootedinCalifornia has photos of the bronzy-red new growth they get in the spring, almost like floral bracts. On the strength of Mr. Manzanita’s recommendation, I sold it to him while I was volunteering at the sale last year, and so far he seems satisfied. Whew.

Cactus Jungle has a photo of the berries and calls it a favorite, and Las Pilitas is bullish on it, too. More manzanita photos are below. (more…)

New Zealand Wind Grass and Salmon Beauty Yarrow

There’s a quotation I can’t quite remember, something about a bear riding a bicycle, that the impressive thing is not how well he rides, but rather that he rides at all. That’s my motto for appreciating the garden today. Nothing looks especially prime, but there are a surprising number of things in bloom, more than I thought before I started prowling with a camera and started compiling a list.

Woolly Blue Curls, Trichostema lanatum, this week

Woolly Blue Curls, Trichostema lanatum, last week

The recent storm knocked the last of the curls off the woolly blue curls. It’s my favorite of the plants blooming in the garden this month. I should probably give more respect to the rosemary plants, which pretty closely resemble the woolly blue curls, but it’s harder to get excited over them, even though the creeping rosemary is in full bloom and is probably the best habitat plant in the garden right now. I probably judge it by the company it keeps.

Salvia spathacea, Hummingbird Sage

I’ve noticed that most California garden bloggers seem to have at least one species of salvia blooming for this month’s bloom day. We have Salvia spathacea, hummingbird sage, bearing a single bloom stalk which fell over during the last storm. So far I’ve never had more than one bloom at a time from these guys, but I’m not complaining about anything that blooms in December; our other salvias — S. chamedryoides, S. mellifera, S. mellifera ‘Green Carpet,’ and ‘Hot Lips’ — don’t have flowers right now.

Woodland Strawberry, Fragaria vesca

Mexican Evening Primrose

The list of everything in bloom is below. Today being in December, I’m not fussy about the quality or quantity. If the plant has a flower, it makes it onto the list. (more…)

Aspens with California Poppy

Aspens in the Bay Area? Somewhat in keeping with snow on Mt. Diablo, not really the popular image of our area, but there they are. According to Sunset, P. tremuloides ‘generally performs poorly or grows slowly in lowlands; usually short lived in warmer climates.” The ones at the Tilden botanic garden seem to be doing well, though it’s true they aren’t large and did probably grow slowly. They were definitely one of the most beautiful things in the garden when I stopped off on my way home the other day. We get asked about aspens sometimes and have always advised people to plant birches instead, but clearly aspens can work, so maybe we need to modify that advice. The bot garden is in a cool micro-climate (small valley surrounded by hills) and there was ice on the lawn and on a few of the plants, so that might be helping these aspens. Next year I need to remember to stop off and see their fall color. This has been a good year for fall color in the Bay Area, so they were probably beautiful.

Redtwig Dogwoods with Aspens

Sunset also says aspens make a ‘good background tree for native shrubs and wildflowers.’ Indeed. I like how the redtwig dogwood and the aspens are both somewhat see-through, and how the colors are so strongly contrasting even as the upright forms are so similar. We’ve planted redtwigs against a light-colored wall a few times, and last week we planted a yellowtwig dogwood against a brick chimney. The line of aspens is just as architectural and works just as well for a backdrop.

Specimen Manzanita with Manzanita Backdrop

One of my reasons for stopping at Tilden was to look at native plants in the winter and see what was blooming in December (Answer: not much, a few late blooms amongst the deadheads on some buckwheat and erigeron species, two raggedy grindelias still blooming, a few stray off-season blooms, and about one fifth or one quarter of the manzanita species.). We talk to a lot of people who think natives only look good for about half of the year and sometimes I find myself believing that a bit, too, so it was good to walk around and see which plantings looked good and which ones would look ratty to that percentage of the population out there who are skeptical of natives. A lot of the garden and a lot of the plants were looking really beautiful, even though it was a gray day right after a cold storm. The rainforest section was looking great (though it was too dark under the canopy to take photos) but I don’t think there’s much debate about how great the woodland natives can look. Probably the biggest problem for northern California natives is just that many people don’t think of them as California natives, instead mentally classifying them as Washington/Oregon natives.

California Fuchsia Planting

I think that when many people say they don’t like natives, they have a mental image of California fuchsia in winter, and when other people say they love natives, they have an image of Cal fuchsia in summer. This is a successful planting to my eyes, but this look seems like an example of what makes some people hostile to natives, a wild-looking plant in a rather wild-looking planting. It also seems to reflect the established popular image of a ‘native planting,’ even though natives can be used in so many other ways and to create so many different looks. I’ll try to return and take a photo from this same spot when the Cal fuchsias are blooming, because they are really pretty in bloom.

Coastal Bluff Planting

The buckwheats, another species not known to shine in the winter, looked good in some plantings and not so good in others. The Coastal Bluff section has a strong design, so the prominent buckwheat in the planting also looked fine and the planting would still look fine even if the buckwheat were replaced with a dying-back Cal fuchsia.

Cold Frame at Tilden

Hello Dudleya

The desert section had some cold-frames out in the southern California desert sections. There’s no question about Agave shawii looking good in the winter. They’re really a Baja native that had a few populations on our side of the border, but those populations have been displaced and now might only exist as revegetation plantings. San Marcos Growers says they’re growing it, so it might start showing up in nurseries more often. Apparently, it’s really slow from seed.

Ninebark Thicket

The ninebark thicket (Physocarpus capitatus) reminds me of a crustacean, either a limpet or maybe a barnacle. I doubt this is going to inspire many people to plant ninebarks or shear them into a limpet shape, but it’s actually being used pretty well here, an effective way to make a certain type of habitat plant look intentional and not too wild. And I bet the birds love it. It looks better than the Salvia leucophylla, which is generally considered more garden worthy but was looking just as deciduous and thickety as the ninebark. In fairness, the S. leucophylla is planted in a tough spot, up against a bridge on a steep slope leading down into a creek.

Sugarbush, Rhus ovata

I just planted Rhus ovata (Sugarbush, an evergreen sumac) for the first time, three of them at my parents’ house. The Watershed Nursery has had a supply recently, one of the first times I’ve seen them available. ( — edit — my bad, I realized that I planted the other evergreen sumac, Rhus integrifolia.) Hopefully the ones I planted will look as good as they do here. I like the flower buds as much as I like their little white flowers. This one here looks ready to do a huge bloom in February or March, that time of year when even the native skeptics agree that California natives look beautiful.

Update — And here is a March photo of that ninebark thicket in leaf. Still not the most ornamental plant in the garden, but not too bad.

‘So if the bird flies away, or if you’ve identified it, you can turn your attention to the tree in the same view, without moving your binoculars or telescope, and have a whole new challenge of something to identify.’ Sibley

Sibley came out with a tree guide! I haven’t yet seen any mention in the garden world, but the birding blogs are on it. 10,000 Birds has a review and an interview, and there’s a 3-part interview with him in Birder’s Magazine. He put together the guide as a birder rather than as a botanist, writing with birders as his target audience, and it’s interesting to see the elements of his bird book carry over into a tree guide.

The most obvious carry over is the life list at the back of the book. I don’t think I’ve ever met anyone who keeps a life list for trees, though the idea is intriguing. Bristlecone Pines were certainly something I felt I needed to see, and the east coast members of my trail crew this summer arrived out here determined to see a Giant Sequoia before they headed home, so the idea does make some sense. It might be interesting to keep track of how many different trees I can see just in the Bay Area.

Instead of photographs, the book uses paintings, which work better for birds and seem to work better for trees, too. The guide includes native and non-native species, making it more useful to me than, for instance, my Audobon guide which only includes native species. I find I already know a lot of the California species, but that it’s the tall non-native shade trees, trees I rarely plant or buy at the nursery but sometimes find in clients’ yards, that I need help identifying. I tried out the book with a couple of trees, the English Walnut in our yard and the Red Oaks where I was working today, and it seemed easy to use.

And it was nice that I went through the ID process without a key. Keys went out of style in the birding world a long time ago, and I’ve never liked using them for trees; they seem like a relic from old-fashioned, rote-style learning. In the Birder’s magazine interview, Sibley says he wants readers to engage more directly with the book.

‘I really wanted the book to work the same way the bird guide does. That is, if you see something interesting, whether it’s a leaf or some odd bark or an unusual type of fruit, you can open up the book and just start flipping through the pages and try to find a picture that matches.

‘I think in the long run, that’s actually more helpful and more educational than working through a key, because after you’ve done that a few times — flipped through the pages of the book, looking for things that match — you’ll realize that if you’ve seen an odd fruit and it’s not an acorn, you can skip the whole 40 pages of oaks in the middle of the book. You start to get a sense of what the variation is in all the types of fruit. Pretty soon you’ll be out in the field somewhere and say, “There’s an odd fruit. I don’t know what that tree is, but I know I’ve seen that picture in the book, and I think I remember it being toward the end of the book,” and flip through the pages and find it and put a name to it.

‘By flipping through the pages and getting an overall sense of what’s out there, you subconsciously begin to understand larger patterns — which families are similar, which families are different, what makes all the oaks similar to all the other oaks, what makes willows and poplars so similar that they’re put in the same family. You’ll develop an understanding of that simply by flipping through the pages of the book.’

I know I became a more knowledgeable birder when I discovered Sibley’s bird book. It’ll be interesting to see what I learn from his tree book.

— Addendum —

I have noticed signs that the guide was written by someone from the east coast. For instance, the guide does not include ceanothus or manzanitas, an omission in my opinion. Sibley’s definition of a tree is ‘anything that you can walk under,’ and manzanitas and ceanothus definitely meet that standard, though I suppose the 30 foot tall manzanitas and treelike ceanothus are known primarily within California native plant circles. And at the same time as the guide excludes manzanita and ceanothus, the guide includes the less treelike Toyon and the less common or iconic Western and Utah Serviceberries and the Mountain Mahogany, probably because there are large old specimens in some of the arboretums back east and in England. I say this not so much a complaint, but rather as an observation, something to maybe fix in future editions; the book is a national guide with a national perspective. And as I was saying, I already have plenty of books for the native trees. Interesting, though, that I find it most helpful for identifying the east coast and european specimens that I find in California gardens.

Ornamental Laundry

We don’t have a ton of stuff blooming in our garden for November. Our laundry is actually the biggest show of color today, with one of Anita’s shirts nicely matching the bloom color of the Spicebush and the Fuchsia. The spicebush is mostly done blooming, but the fuchsia has climbed into it and from a distance the fuchsia flowers make it look like the spicebush has more than its three or four remnant blooms.

Fuchsia and Spicebush

Sidalcea malviflora

I hadn’t noticed that the Sidalcea malviflora plants have woken up, but one is starting to bloom already.

Arctostaphylos John Dourley

Manzanita ‘John Dourley’ has opened a few flowers.

Bearded Iris

Some of our Bearded Irises decided to do a fall bloom. This is the darkest one of the batch, my favorite.

Blessed Calendula

And Blessed Calendulas. We always have some orange calendulas blooming (and needing to be deadheaded). Alyssum, a rosemary, the last basil plant, two Salvia chamaedryoides, and the cannas in the graywater planter are the other plants blooming in our yard. Check out Garden Bloggers’ Bloom Day at MayDreamsGardens to see lots more plants in bloom.

Folks in Anita’s winter vegi classes were interested in what specific varieties to grow, so I thought I’d post the list of what we’re growing in our Richmond Annex (fog belt, zones 9b and 17) garden for this winter. Everything we’re growing is a variety that we’ve done at least one of the past three winters here, which seems a little boring and unadventurous, but should produce reliably.

Favas Beans
Snap Peas ‘Cascadia’
Beat Greens “Lutz Salad Leaf’
Romaine Lettuce ‘Freckles’
‘De Cicco’ Broccoli
Yellow Onion Sets
Garlic ‘Nootka Rose’
Kale ‘Dwarf Blue Curled’ and ‘Dinosaur’
Mustard ‘Red Giant’
Arugala
Mache
Miner’s Lettuce

A pretty standard list, everything reliable. Alpine Strawberries, a Rocoto Pepper, Regular and Garlic Chives, and a couple of Blueberries are the year-round residents. We’re still harvesting Celery, Leeks, and Zucchini’s, and we’ll probably plant out more Snap Peas and Kale or maybe Rainbow Chard in those spots in February.
