petals and parasites

5 Comments

The garden is turning decidedly brown as the temperatures warm and the dry summer gets underway–Sounds like a perfect time to revisit high spring in the local foothills. Or maybe that’s just a ruse to get an excuse to show some photos I didn’t get to posting yet. Pick whatever motivation sounds good to you…

When I visited Crestridge Ecological Preserve last May the rock roses (Helianthemum scoparium) were announcing themselves assertively. The little low plants were at their peak and vibrated with dozens to hundreds of brilliant yellow five-petaled flowers on each plant.

And anywhere that you saw rock roses you’d see hundreds of rock rose petals beneath the plants. I was trying to decide what I liked better, the flowering plants, or the red earth beneath them, dusted gold with fallen petals.

Rock rose. Cool plant.

“Cool plant” might not be your first reaction to the dodder (Cuscuta californica) that was everywhere. Lacking chlorophyll, its only way of surviving is to latch on to a host plant and suck on its vital plant juices, depleting the host while growing extravagantly all over it.

Someone on the trip pointed out that DNA work has established this as a member of the Convolvulaceae, the same family that includes Calystegia, the genus of native morning glories, as well as Convolvulus, the genus that contains the common garden morning glories. The new draft Jepson manual follows this classification.

If you’ve planted the garden morning glories, only to recoil in horror at how they coil over absolutely everything in their path, you’ll recognize the growth pattern that dodder adopts. Like morning glories, it twines like crazy. And, it’s parasitic! Extra bonus!! Dodder is an annual, so that even though it feeds off its host, it does so for only part of the year, mainly during the growing season when the host stands the best hope of keeping up with the dodder’s demands.

All that ickiness aside I happen to love how the stuff looks, twiny and golden, working its way through the landscape. Visually, it does what nothing else in the landscape does. I’m not the only person struck by its forms. There’s a fairly abstract, very modernist photo of dodder in Laguna Beach that was taken by Edward Weston way back in 1937. [ Check out the image at the Center for Creative Photography, in Tucson. ]

So, as far as I’m concerned: Dodder. Cool plant.

About the time I took this trip I happened to open up the Sunday comics to see the week’s Bizarro single-panel. I won’t stomp all over copyright and lift the image for here, but you can view it on Dan Piraro’s blog [ here ]. But let me try to describe it:

Night. Suburbia. Exterior of a house with a lawn and low, mounding foundation plantings. A sidewalk leads away from the front door. Tight shot of a couple who are leaving the house.

The woman, smiling, says to the man, “What terrific hosts.”

Behind them, in the doorway of their home, stands the host couple. Light spills out from indoors and onto the stoop. The man wears a pair of round black glasses, “Harry Potter glasses” you might say, though you sense that he was wearing them long before Harry Potter existed. He waves a weak farewell.

Next to him the hosting woman stands, her hands clasped. She does not look happy. She speaks.

“What incredible parasites.”

Who’d ever think that the host/parasite relationship would ever be material for the funny pages? Talk about timing, talk about coincidence, the trip to Crestridge, the dodder, the Sunday comic…

visiting crestridge

For today’s Garden Bloggers’ Bloom Day I’m doing something a little different. My garden looks a lot like it has in recent posts, so I thought I’d take you along on a tour last weekend of Crestridge Ecological Preserve, in San Diego County, a little over half an hour from the coast. The flowers were out in force.

One of the interesting narratives of this place is how a landscape responds to being burned. This preserve and many of the homes around it burned intensely in the big 2003 Cedar Fire. A lot of the homes nearby with their new tile roofs and crisp, new stucco look like they’ve been rebuilt out of the ashes.

Same goes for the plants. The Engelmann oaks that help define the character of the preserve burned. But many are bouncing back. Really, if it weren’t for the burned snags it’d be hard to guess that this area was cinders seven and a half years ago.

The Preserve features a small visitor kiosk designed by James T. Hubbell, the county’s best known proponent of organic architecture. Wood post-and-beam construction with straw-bale infill makes up the walls of the one-room space. Floors are a mix of flagstone and tile mosaics. Very groovy.

Around the kiosk is a native plant garden funded by a grant by the local CNPS chapter. Unlike the landscape around it, this garden receives some irrigation to keep it looking more garden-like. But today the garden extended seamless into the surrounding landscape.

The floral highlight of the trip is the the preserve’s stand of the rare Lakeside ceanothus, Ceanothus cyaneus. It’s vivid, dark color and big floral heads make it what must be one of the most spectacular of the ceanothus species. It’s not particularly garden tolerant, but given perfect drainage and no water once established, it might hang around for a few years and stop traffic passing by your garden.

On this trip we saw this lilac, as well as late-blooming examples of the much more common but less spectacular Ramona lilac, Ceanothus tomentosus, and some intergrades that look like they’re the love children of these two species.

monkeyflower spectrum

Yesterday I went out to Crestridge Ecological Preserve, about a half hour’s drive from coastal San Diego. There will be lots of photos from the trip, but here’s a little panorama to get started, featuring the common sticky monkeyflower, Mimusus aurantiacus.

Around here you can easily find clones of it that are soft apricot-yellow, or ones that are orange, or scarlet. I’d read somewhere that pretty much all the forms west of Interstate 15 were scarlet, and all of those east of it were apricot. It was supposed to have something to do with coastal plants supposedly being pollinated by hummingbirds, while those inland were visited by bees. (EDIT, May 9: Another source I just looked at mentioned that the primary pollinator of the pale form was the hawk moth, which makes sense for an adaptation towards larger, paler flowers.)

Well, what do you make of this? The top composite shows the plants, below are the details of the flowers on the plants. (You’ll definitely have to click to enlarge this photo to make sense of this wide panorama.) On this north slope were five plants that showed the complete range from apricot to scarlet, and the plants were arranged sequentially as if they lines in a spectrum. Crestridge is a couple dozen miles east of I-15, so I think these plants blow the I-15 hypothesis out of the water.

I’d guess the real answer will implicate plant-sex and require a more nuanced understanding of how these different color forms establish themselves in different areas.
