Here’s another view of the woodland strawberry planting I showed on bloom day. The strawberries have been rather mealy this year. Two years ago they were good, last year they were okay, but this year they aren’t much good at all. I’m guessing that might be because of all these April and May rains. Also, the leaves are looking somewhat chlorotic up close, so they might need to be thinned out to refresh them. We originally put these in as a cheap, low-water groundcover, but after a big harvest of berries the second year we started to think of them as an edible deserving of more attention and respect. If anyone has a suggestion for getting fruit production back up, please let me know.

This planting started with three 2″ stubbies and had full coverage within two years. Normally, I’d be afraid of a groundcover that can spread this fast, but it’s pretty easy to control because it does all its running above ground. California Native Plants for the Garden uses a photo of it to illustrate the potential ‘weediness’ of some natives, but personally I like the look of the strawberry with the irises and alliums rising out of it. Any drought-tolerant, evergreen, native groundcover that produces berries is okay with me.

Sidalcea bloom, Sisyrinchium and Fragaria foliage, in February

The sidalceas disappeared into the strawberry patch a couple of years ago, with only their flowers showing unless you hunt for the leaves. I like its ‘What plant are those flowers coming from?’ effect.

Mostly Fragaria vesca

We put in a single Beach Strawberry, too, which is now the dominant plant in its own corner of the planting. It has sent out runners through the rest of the planting that send leaves up for a bit of textual contrast. Before growing the two strawberries, I used to get them confused, but side by side it’s not hard to tell the difference. The beach strawberry has a harder, darker, thicker, glossier leaf. Flowers are bigger and often set deeper within the foliage. I’ve never seen a berry on it. Woodland strawberry unsurprisingly prefers part shade, while beach strawberry is happiest, again unsurprisingly, in coastal full sun, but both plants have worked in pretty much every situation we’ve tried them.

Quercus garryana or lobata

This is one of the best oak trees I’ve seen, in a Lafayette yard where we did some work a couple of years ago. I was back to check on the pondless waterfall this past week (still no leaks or pump problems, knock on wood), and I was glad to see the oak is just as amazing as I remember. At the time I thought it was a Garry Oak, but apparently the various arborists and oak experts who have looked at it have given several different ID’s, saying it could be a Garry Oak, a Valley Oak, or a hybrid between the two. They also differ on their estimates of its age. Everyone agrees, though, that it’s big and old and beautiful.

Wow

To my complete astonishment, the highlight of my day yesterday was the Lowes parking lot in Concord. It has the biggest, bloomingest, most successful wildflower meadow I’ve ever seen. I have some cynical thoughts about it — it was probably done to appease environmentalists or the planning commission, it was probably amended with all the damaged bags of Miracle Grow, Monsanto probably supplied the seed mix — but it was impressive nevertheless. Not something I expected to see at a big box store.

Tidy Tips, Layia platyglossa

Tidy Tips predominated in the bio-swale, Chinese Houses on the berms.

I had never been to Lowes before and it turned out to be even more like Home Depot than I expected, but my hat’s off to whoever is responsible for that meadow.

Elephant Tree at Dusk

Here are some more plant photos I took in Baja in the desert around San Ignacio and Cerro Colorado, along the coast near Bahia Concepcion, and further south near Cabo Pulmo. My first go at taking photos in low desert, pretty fun, as my favorite things in the plant world are multitrunked trees with interesting form and bark, and Baja is pretty much an entire landscape of beautiful multitrunked specimens with interesting form and bark. Elephant trees were my favorites, but there were other stunning ones: Palo Verdes, Palo Blancos, Cardon Cactus, Organ Pipe Cactus, Adam’s Tree known in Spanish as Palo Adan (Fouquieria diguetii, the southern form of Ocotillo) and Limberbush (Jatropha cuneata), which I’d never heard of but really liked. So many good ones. I suppose some of them are technically standards or semi-standards, but practically all of the plants down there grow with the interesting form I associate with multitrunk trees.

Cardon

The Cardones come in graceful or stubby forms.

Burseras

We saw hillsides that had an amazing specimen every twenty or thirty feet.

Torote means ‘twisted.’

Zero Leaves, One Bloom Cluster

Lots of Leaves, No Flowers

In the drier sections most of the Fouquierias were leafless, with maybe a few token blooms to keep the hummingbirds and visiting gardenbloggers happy; down south a lot of them were in full leaf with fewer flowers. Does anyone know why they’re called Palo Adan or Adam’s tree?

Fouquieria diguetii at Playa Requeson

I remember something incredibly spiny was keeping me from backing up any more for this photo.

Palo verde, aka Desert Willow

I’m partial to the name palo verde, but desert willow, another of its common names, seems appropriate too. Leafless they looked a lot like Japanese maples, but in full leaf they were indeed willowy.

Green Sticks

Roadside Palo Verde

As far as I’m concerned, they’re pretty even when they grow along the highway with trash scattered around.

Mesquite Tree

We started calling the Mesquites ‘Palo Gris’, because their trunks are gray but their green twigs and foliage resembles a Palo Verde. They’re actually a pretty sweet little tree, I think, just not as showy as the Palo Verdes and Palo Blancos. I read somewhere that some miners in Baja once found a root 50 meters deep.

Palo Blanco

Palo Blanco is a perfect common name, but if Palo Verde gets desert willow for a second common name, I think Palo Blanco should also get a second name and be called desert birch. They did seem biggest and happiest at the bottoms of washes and arroyos where they could find some extra water.

Cerro Colorado in the distance with Volcan las Tres Virgenes beyond it

I mentioned that we started bicycling from San Ignacio, an oasis town about half way down the Baja peninsula. Before we started riding, we spent a few days exploring the desert and checking out the plants there, and especially checking out the succulents on Cerro Colorado, a volcanic hill a few kilometers from town.

Closer to the hill

If you’re interested in succulents, Cerro Colorado is the place. The Center for Sonoran Desert Studies/Desert Museum did a survey and found 44 unique species, which they claim is the highest number of succulent species of any spot in the southwestern U.S. Would that then make it the highest number of any spot in the world? I don’t know, but there’s a ton of succulents there, regardless. Anita and I did our own personal survey and identified 19, which we’ll obviously have to improve before we can start leading botanical bicycle tours of Baja (now accepting reservations for winter 2031). Looking at the species list for the hill, I see that it broadly defines a succulent as just about any plant that has tissue designed for storing water. The list includes a couple of Asclepias species and a bunch of caudiciform shrubs and vines: cucumber relatives, shrubby euphorbias, a wild fig, and two species of elephant trees (Bursera). Some of those are plants I wouldn’t have considered succulents, but then I’m not a botanist, and with 24 species of cactus, it’s not exactly lacking in conventional succo’s.

Barrel Cactus

I think these are two different species of barrel cactus. I lost track of all the chollas. We could tell there were several different types, but the desert museum lists eight, including hybrids. A couple were jumpers.

Agave cerulata subcerulata

It’s probably the spiniest place I’ve ever been, but plants are spaced far enough apart that we could make our way through it as long as we occasionally pulled spiny branches out of our way. I found that walking with all those spines everywhere kept my attention always focused on my immediate area and each plant immediately in front of me, so that I was constantly looking up to discover yet another awesome specimen in front of me, over and over and over.

Elephant Tree, Bursera microphylla

Elephant trees get the nod as my favorite plant down there. Has anyone seen or grown one in the Bay Area?

Red Elephant Tree, Bursera hindsiana

This is probably the best trunk I saw on a Red Elephant Tree while I was down there.

Limberbush, Jatropha cuneata, in the Euphorbia family

There were two kinds of Jatropha. The other one, J. cinerea, looks a lot like the mexican redbud, but with somewhat swollen-looking branches and twigs.

Palo Verde

The hill had great palo verdes. They aren’t a succulent, but they have chlorophyl and photosynthesize on their wood, which seems like justification for getting in with the succulent photos.

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, wears a sign with that title during the plant sale every spring when he 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.

Arctostaphylos pajaroensis Paradise

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…)
