While my last post was dedicated to an easy seed propagation project, this one details a couple that were a little more labor-intensive. Still not hard, just a little bit more work to pull off.

Sarracenia Night Sky, a hybrid of S. leucophylla and S. rubra gulfensis.
I’ve posted about my pitcher plants a few times before–Sarracenia species from the American South and some hybrids–and this is the first year I’ve tried sowing my own seed. All eight species (or nine, or ten or eleven, depending on the expert you listen to) are inter-fertile, and hybrids between all of them are possible and have been made at one time or another. The hybrids, too, are generally fertile, and you can go crazy with the genetic possibilities.

Sarracenia Dainas Delight, a complex hybrid of S. xWillissii and S. leucophylla.
For creative sorts you can arrange garden plants in interesting ways, but with this genus you could also design the very plants that you grow. If you live in the heart of pitcher plant country, this might be a problem. Bees could carry pollen from your hybrid plants to nearby native species and create some new unnatural hybrids. But the genus never crossed to this side of the Mississippi River so Californians can play Doctor Frankenstein all they want without worrying about messing with the native population beyond our castle walls.

Mature seed pod of Sarracenia flava.
So…I began in the spring making some hybrids, and the pods began to ripen in August, with the last pods just finishing up ripening right about now.

Closeup of the previous Sarracenia flava seedpod. This one contained almost 500 seeds. You can see them practically jumping out of the pod.
The seeds require a cool, damp period in order to germinate. I emptied the pods and put the seed in a plastic bag with a few strands of moist chopped sphagnum moss, one bag for each cross. And into the fridge they went for four weeks.
After this period of cold stratification I sowed the seed on the surface of chopped sphagnum moss which I’d layered on the top of post filled 50/50 with a sand/peat mixture.

Next, I put the pots into a clear plastic box, poured in half an inch of standing rainwater, closed the lid, and put them near a window that faces south-southeast. If everything goes well–and it looks like it did–the seedlings begin to emerge in two to four weeks. Warmish weather is best, though you don’t have to be too fanatical. This batch experienced the recent 90– to 100-degree days as well as many cooler days in the 60s. As long as the seed think it’s spring, they’ll begin to germinate.

That’s pretty much it. Some people place the seedlings under constant bright lights and 70-plus degree temperatures for up to three years to speed them up to maturity. I’m hoping that bright daylight in a warmish interior spot will give them enough of a boost that I don’t have to resort to the equivalent of putting the plants on steroids.

Yearling sarracenia seedlings of the cross S. (Melanorhoda, Triffid Park x rosea luteola).
And here you see the reason why people might try to accelerate growth. These are year-old seedlings from a cross by Brooks Garcia that I sowed a year ago, thinking I’d practice on someone else’s cross before attempting my own. I grew these in my unheated greenhouse which has fairly low, less-than-ideal lighting conditions. They did get some bottom heat during the coldest months of the year.

Drosophyllum lusitanicum, a couple months old.
The other carnivorous plants I’m propagating this fall are of this Mediterranean-region species, Drosophyllum lusitanicum. While virtually all carnivorous plants are creatures of swamps and bogs, this one is unique in that it comes from fairly dry areas with be limited summer rainfall. Unlike the preceding sarracenia bog plants, this species could actually thrive in California’s wet-winter, dry-summer climate without too much additional life support.
Its common name is “Dewy Pine” because the leaves have little tentacles tipped with sticky bug-catching fluid that looks like dew. But Barry Rice mentions a much cooler moniker: Its Portuguese name translates into “Slobbering Pine.”
This plant and the preceding Sarracenia do catch insects. It’s a contradiction I’m trying to come to terms with. I plant a lot of California native plants, which provide nectar and other food for all sorts of winged and crawling creatures. And then I have these little monsters that actively trap and consume them. Call me a man of contradictions. In the end I hope I’m doing lots more good than bad.
I only know of one seller who ships Drosophyllum so you pretty much have to grow your own from seed if you want one. (I got my seed from the seed bank of the International Carnivorous Plant Society.) The little black seeds have a hard coat that slows down germination. If you have some 220-grit sandpaper around that’s not a problem. Just lightly–and I mean lightly–rub the seed between two sheets of the sandpaper until a patch of the black seed coat is worn away to reveal the white layer underneath. Then pop them on top of the same mixture you’d use for germinating Sarracenia and keep the mix moist with good-quality water. Germination for me was about two to six weeks, no cold stratification necessary.
There you have it. With both of these kinds of plants it was a little more work than my last post growing bladderods from seed. But really, it isn’t that hard if you’re patient.

Fall: Prime time to sow many seeds in California’s mediterranean climate. Self-sown generations of clarkia, poppies, baby blue eyes, buckwheats and lupines are showing up all around the garden.
But this year has pulled me in lots of directions and I haven’t put a lot of effort into sowing seeds. Also, part of this lack of motivation is an attempt to accept the reality that the garden is pretty full as it stands, and I try resist the delusion that a plant growing from a tiny seed won’t take up as much space as a nearly mature one from the nursery. Consequently the only active seed-sowing I’ve taken part in has been limited to two very different kinds of plants: the California-native bladderpod and some carnivorous plants.

The bladderpod was mainly an experiment. The pods that give Isomeris arborea its common name are full of seeds the size of dried peas. How easy would they be from seed?

Very easy, as it turns out. I opened up a couple pods and buried the seeds about a quarter to half inch in these pots just two weeks ago. Here they are, showing almost 100% germination and phenomenal seedling vigor.

The more upright of my two young bladderpod plants
Now that I see they’re really easy from seed I can check out the other thing thing I was curious about. I have two bladderpods in the garden. One is slow-growing but is assuming a nice upright posture. The other is an exuberant floppy mess of green-gray leaves and yellow flowers. Both forms have their use in the garden, but I was really hoping for more upright growth patterns when I put them in the garden.
My seedlings come from the more upright plant, so we’ll see whether they follow mom’s growth habits when placed in various locations around the yard. Is the difference in growth habit nature or nurture? Might I have a consistently strain of upright-growing bladderpods on my hands?
In the native plant community growing specific strains or cultivars is often looked down upon as reducing natural variation and dumbing down the gene pool. But in the garden it’s useful to know what kind of plant you’re getting. A gardener might be disappointed to end up with a low mound instead of an open upright shrub. The customer might never buy another native plant again and instead fill their yard with hydrangeas. They’d spend thousands of gallons watering their hydrangeas, there’d be no more water for people and plants, and civilization as we know it would collapse.
Anyway, so far this has been really easy. Next post I’ll look at my more high energy-input efforts to grow some carnivorous plants from seed.

Can you call a patch of dirt of about eight square feet a garden? I’m starting to consider my recent planting of succulent a miniature little dudleya patch. But a garden?


I’ve already shown off the new species I picked up at my recent native plant society’s sale. Recently I finally got around to giving them their place in the larger garden. The location is more shade than I’d like–maybe four to six hours’ sun with afternoon shade. Situated on the edge of a somewhat irrigated area devoted to fruit trees it might be more moisture than the plants really want. Most of what I’ve read about dudleyas suggests using an inorganic mulch like pebbles instead of the bark that you see here. Still, there’s an older clump of Dudleya edulis that you can see in the near-back of these photos. The clump has done well so far, so there’s hope for the new arrivals.

There are eight Dudleya species in this area of the garden, but they get to share space with a couple other other succulents, a blackish-purple aeonium and the blue chalk fingers plant (Selecio mandraliscae) that is getting to be pretty popular down here as a groundcover. The finger-shaped leaves play nice with the fingers of several of the dudleyas most easily seen in the upper left picture: edulis, viscida, and attenuata.
In the center of the space is this ornate column made out of cast concrete. The previous owners of the house must have gotten a good price on architectural molds because there’s this little column, and another, much larger, outdoor feature that looks like part of a Doric column. Either the owners were of…um, eclectic?…taste or they were postmodern two decades before Charles Moore designed the Piazza d’Italia in New Orleans. The features are made of concrete, however, so it’s a little hard to do much more than try to live with them. Maybe one day I’ll bring the diamond-bladed saw to deal with this feature. Still, living with other people’s choices can sometimes push you towards a solution you never would have come up with yourself.


So, what to do with this column in the Dudleya Garden? One obvious thing would be to place on top of it a mirrored reflecting ball, sort of a garden gazing ball that was popularized in Victorian times. I want to be a little more subversive, though. How would a bowling ball hold up to the elements? I wonder. But for now I’m auditioning a couple of rocks, an irregular chuck of green stone that John picked up somewhere, and a rounded river rock of the sort that you dig up in gardens in my neighborhood, remnants from the days when this land lay many hundred miles to the south in what’s now Mexico, days when the land was lower and drained the big river that formed the area’s Copper Canyons.

In a rock wall about fifteen feet away I had space for a single plant. This will best represent how many dudleyas are found in nature: on steep ground, often growing out of what looks like no soil at all. This is Dudleya virens ssp. hassei, a species found only on Santa Catalina Island. While some dudleya species will form a single, perfect rosette, this single growth should before too long develop into an ever-widening clump of starry foliage.
This little planting in the rocks should soon look a little like something you’d find in nature. But the other patch of dudleyas with maybe a mirrored disco ball? Well, that’s definitely going to be a human-created garden.

Our weekend Netflix viewing was The Savages, a 2007 film starring Laura Linney and Philip Seymour Hoffman who play a sister and brother who are called in to care for their ailing father. The siblings leave New York City and Buffalo in the fall to pick up their father in Sun City, Arizona.
I laughed at some of the establishing shots of the landscaping in Sun City. I had to share.

Long rows of these soccer ball trees are shown all over Sun City.

Houses with these ball shaped trees…

Big palm trees, but the planting budget didn’t allow everyone to get one of their own…

This hedge really got me laughing. What emerges from behind the hedges two seconds after this shot is even funnier…
As far as the film, I liked it. As expected, the siblings have issues between them, including some sibling rivalry that’s simmered for four decades. But all in all they’re adults trying hard to do the right thing for their father: nothing too Hollywood and cloyingly uplifting, but nothing that’s a real downer, either.
Of course such mature behavior would never fly in many families I’m familiar with. Overall it left me with the feeling that’s best summed up by a bumpersticker John has that hasn’t made it onto a vehicle yet: My Family is More Dysfunctional than Yours.

When my parents retired they moved out of their house of almost twenty-five years in the Los Angeles area. Not wanting to pick favorites between their two children they decided on a modest house in a new development in Oceanside, halfway between my sister and me.
Like many new homes the landscaping that came with the place was bare-bones: lawn, with a single podocarpus sapling next to the front curb. The blank slate excited my mother, who was looking forward to putting her stamp on a new piece of property. I helped her plan the yard, construct the raised beds, move dirt and do some of the planting. In the end, though, almost all the plant selections were hers: oleanders, pittosporum, geraniums, roses, azaleas, agapanthus, bird of paradise, Japanese maple, citrus, stone fruit trees, plus selections from the other plants that were being promoted twenty years ago.
When my mother died in the late 90s it left my father with a yard that wasn’t exactly what you’d call low-maintenance. And Oceanside wasn’t a quick drive up for me so that I could help tend it. Several years later he moved out, leaving the gardener’s garden in the hands of renters, many of whom never watered or tended it.

One corner of the back yard, with some survivor plants and others that hadn’t fared so well.
Last summer I had a chance to stop by the house for what will probably be my last visit. Many plants were still alive, thanks in part to what had been a moderately moist winter and spring, with more thanks probably going to the neighbors who watered their lawns and unknowingly kept the ground moist for thirsty roots from next door to sneak under the side fence.

A detail of the preceding photos, showing a bright green native Baccharus, coyote brush, that had colonized the bed. It looks much happier than most of the non-natives.

Lavender, crape myrtle and citrus are still hanging on. The lawn is long gone, however.

The side yard, with overgrown honeysuckle and pittosporum.

A rose and weeds in the front yard, probably surviving from overspray from the neighbor’s sprinklers.

I’d always thought Japanese maples were water hogs. This one didn’t seem to mind the abuse, though I suspect its roots wandered far next door looking for water. To the left behind it is asparagus fern, a plant that will survive long after the next zombie apocalypse.

Sheffleria, the fairly indestructable houseplant, turns into a fairly indestructable subtropical screen outdoors when planted next to the neighbor’s well watered lawn. The adjacent azaleas weren’t so resourceful and were pretty crispy-brown.

My mother liked her geraniums. This survivor was just about the only thing blooming that day.

A steep and weedy slope drops to the back property line. A narrow riparian corridor behind the house was thick with untrimmed willows, doing a terrific job of screening out condos and a Home Depot that have gone up beyond the fence.
The house is in the hands of new owners now. They’ll probably look at the ragged plantings and decide to start fresh, removing most of the scrappy plants and making the yard their own.
If I hadn’t seen the yard in its current state I might have felt protective or territorial. But this visit allowed me to let go. This was once a comfortable and beautifully maintained garden that gave my parents joy. I have those memories, but I realize that’s not what the garden is anymore.
I now feel at peace with whatever the new owners will want to do with the yard. I wish them well.
