Baja Multitrunks

Elephant Tree

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.

The Cardones come in graceful or stubby forms.

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

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?

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

Palo verde

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.

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

Mesquite Tree

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

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.

The Succulents of Cerro Colorado

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.

Various Succulent Plants

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

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?

Bursera hindsiana, Red Elephant Tree Trunk

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

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, Cercidium floridum

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.
