Go and Catch a Falling Star


Padre's shooting star, Primula clevelandii: is a beautiful, ethereal and ephemeral native wildflower that blooms in winter and is one of the first harbingers of spring in Malibu and throughout the Santa Monica Mountains.


Go and catch a falling star,
Get with child a mandrake root,
Tell me where all past years are,
Or who cleft the devil's foot,
Teach me to hear mermaids singing,
Or to keep off envy's stinging,
And find
What wind
Serves to advance an honest mind.


—John Donne, "Song"



In a wet year, shooting stars flourish, covering whole hillsides with delicate pink stars. 

It's easy to catch a shooting star in Malibu in February, when Padre's shooting star, a beautiful and ephemeral native wildflower, blooms, but this flowering is short-lived. Look fast to catch a glimpse of this rare beauty.

You know how they always tell you to memorize the scientific names of plants because thay remain constant? That is not also so. Padre's shooting star was recently reclassified from Dodecatheon clevelandii to Primula clevelandii. The change to primula highlight's this flower's place in the primrose family. Like garden varieties of primrose, P. clevelandii grows from a rosette of leaves. Clevelandii is in honor of San Diego civic leader and avid amateur naturalist Daniel Cleveland.



Daniel Cleveland (1838-1929) founded banks, facilitated railroads, hospitals, schools, libraries—buying 2000 books to start a San Diego library, and co-founded the Natural History Society of San Diego. In return, he is remembered in a host of scientific names for California flora and fauna, including Primula clevelandii.


Spring of 2020 isn't going to be a super bloom—early rain dried out quickly, leaving poor conditions for most wildflowers, but the shooting stars got an early start and are experiencing a moderately strong year.  I photographed this field of stars on the Conejo Valley side of the Santa Monica Mountains. This species likes the kind of north-facing hillside with rain seepage. Because it blooms early, it rarely faces competition from other plants.



Padre's shooting stars range from soft pink to cherry pink to almost white. This is the only member of the primula family in the Santa Monica Mountains, but  that pen-nib-shaped flower is a reminder that the exotic-looking cyclamens one buys at the nursery for a bit of winter color in the house are also members of the primula family.



An almost white shooting star. The only one in a vast field of pink.

You are more likely to spot this beautiful wildflower on the north side of the Santa Monica Mountains, especially in volcanic soils. This is a protected species, so please take only photographs and be careful not to step on the rosettes of leaves—this species is sensitive to soil compression and won't bloom again if it is trampled.



Shooting stars grow from a basal rosette of leaves. Like the garden variety of primrose, this plant is "spring deciduous," dying back after blooming and regrowing from its roots after the first winter rains.


The star-like flowers quickly turn into balloon-like seed capsules. When the seeds are mature, the capsule bursts open, shooting the seeds far and wide like a mini catapult.


The previous year's flower skeletons can provide a welcome clue of where to look for flowers the following year.


This year's flowers blooming among the ghosts of last year's bloom.


So, go and catch a shooting star, but hurry, because like the celestial phenomenon this beautiful flower is named for, it is a fleeting beauty, and this year's flowering will be shorter than usual due to dry conditions and drying winds. 

At the risk of jinxing myself by putting it in print, I'm hoping this post will be the first in a new series of natural history posts in 2020. If you enjoy the Malibu Post, blog please follow us on Instagram @malibupost, check out www.messengermountainnews.com, where I write biweekly articles on nature, history and the environment, and look for a second volume of my book "Life in Malibu," arriving in time for the holidays.

Tending the Garden

Saint Francis watches over the winter garden at the Malibu Post. All photos @ 2016 S. Guldimann



“Neither need you tell me,” said Candide, “that we must take care of our garden.” 

“You are in the right,” said Pangloss; “for when man was put into the garden of Eden, it was with an intent to dress it: and this proves that man was not born to be idle.” 

“Work then without disputing,” said Martin; “it is the only way to render life supportable.”

Voltaire, Candide 




While much of the country is gripped in the icy embrace of the polar vortex, the first rains of winter have already brought Malibu temporary relief from the blight of drought, and the first green flames of winter grass are kindling the barren earth. There is the tantalizing sense that Eden is somehow in reach here, no matter how long the exile from paradise. 



A buckeye butterfly rests on a strawflower in a Point Dume garden. 

All the bleak and dire news in the world can't diminish the hope that comes with the rain, and in our gardens we have a small but real opportunity for conservation and grassroots activism by providing safe earth-friendly habitat for wildlife, birds, butterflies, bees, and humans. 

Planting a butterfly garden now will ensure it is in bloom during peak butterfly season in the spring but will also help year-round pollinator species, including bees, make it through the winter.



Bees gather on a matillija poppy flower. Re-wilding gardens with native necter-producing flowers may be key to the survival of many species, including wild bees, honeybees, and the rapidly vanishing monarch butterfly, which depends entirely on milkweed for survival. The Malibu Monarch Project offers info on butterfly plants for the garden, so does the Xerces Society.


Many birds overwinter in Malibu. Providing a safe harbor with water and shelter for these seasonal residents is an easy and rewarding way to help conserve wildlife.



Supplying clean, safe water for birds is one of the most rewarding ways to help backyard birds. We have dozens of visitors to our birdbath, including this wrentit. Most birds prefer a wide, shallow basin. Here are some suggestions from the Cornell Bird Lab website. Some species are attracted to dripping water—easy to supply by poking a small hole in a bucket or even a plastic water bottle and suspending it over the bird bath. Here's some practical advice on how to do this from the San Francisco Gate.  



A large birdbath may attack bigger birds, like this mourning dove. We've had hawks stop by for a bath—water flies in all directions. A friend with a beach house regularly has sea gulls stop by to bathe. "We had to get a sturdier base," she told The Post. "They used to knock the old one over." All birds appreciate fresh, clean water. Regular draining and scrubbing can help prevent the spread of parasites or illness. Rocks or gravel can be used to raise the level of a deeper vessel, or to provide a "shallow end" for wildlife in a garden water feature. A "lizard ladder" is helpful for preventing accidental wildlife drownings. A piece of bamboo or just a fallen branch from a tree placed at an angle in the water is all that is needed.


Early winter is the best time to plant wildflower seeds, bare root trees, cool weather veggies like lettuce, as well as many native garden plants. It's also the safest time to trim trees—a window of opportunity that is relatively small, since owls, hawks, and ever squirrels begin nesting in late winter.



Winter is the safest time to trim trees in Malibu, but nesting season begins early here. I photographed this cozy tree-top nest and its gray squirrel architect last February.



Here at the Malibu Post we encounter at least ten species of raptors throughout the year, including 
white-tailed kites and on one memorable occasion a peregrine falcon. Red-tailed hawks like this one routinely nest in the neighborhood, so do red-shouldered hawks, American kestrels, barn owls, great horned owls, and western screech owls.

Barn owls are happy to set up shop in outbuildings or even attics, and great horned owls are opportunists who recycle the old nests of other raptors or crows in any tree, even sometimes palm trees, but western screech owls depend on native oaks for shelter. Property owners with room for oaks in their gardens have the opportunity to create habitat for a wide range of species.


Property owners who have room to plant oaks can help encourage oak-dependent native species like this acorn woodpecker.

Gardeners who would like to grow oaks can try their luck sprouting acorns. Native live oaks are easy to start this way, but all types of native oaks, even valley oaks, are easy to start in pots, as are California black walnuts and bay laurel. Just don't leave them in their pots too long. All three species depend on a deep taproot and won't thrive if that root doesn't have room to grow.

It's also a good time to try rooting cuttings or growing root divisions from local native plants. At the Malibu Post we've successfully rooted cuttings of mugwort, black and purple sage, buckwheat, ceanothus, penstemon, golden current, and toyon berry, and failed dismally at white sage; sagebrush; and Mexican elder.



A black sage sprig ready for planting, with the bottom two rows of leaves carefully removed. Black sage is a great garden plant, with aromatic leaves and blue flowers that attract butterflies, bees, and hummingbirds. It's also an interesting substitute for garden sage in the kitchen—a bit mintier and more pungent than the ordinary market variety. 


The cutting is planted in ordinary potting mix and gets lots of water—it is important to make sure the soil never dries out.


Once the cutting has taken root it can be transplanted into the ground, where if all goes well, it will grow into a plant like this.

Hummingbird sage, with its pineapple-scented leaves and beautiful purple flowers, grows well from root cuttings. So do corm-based blue-eyed grass, California native irises, and even some of our native ferns, like polypody and bracken.



Plant some wildflower seeds in an unused corner of the garden right now, and you may have a living tapestry there in the spring. This mix included poppies and owl clover.

Coyote brush, California bush sunflower, and laurel sumac—three critically important coastal sage scrub plants—readily grow from seed. So do many of our most beautiful wildflowers, including poppies, lupin and clarkia. 


Many rare and hard to propagate native species can be found at the Theodore Payne Foundation in Sun Valley or at Bob Sussman's Matilija Nursery in Moorpark. It's worth a winter pilgrimage to both nurseries.



Not all native plants are hard to find. This Cleveland sage has become a garden favorite and is readily available. This plant came from Cosentino's Nursery here in Malibu. Local nurseries an often offer expert advice on the best plants for the area. In the rush to replace lawns with drought tolerant options many Malibu residents have inadvetantly turned their gardens into deserts. Grass is not ideal from a drought perspective but the right kind of grass and the right watering schedule can greatly reduce the amount of water a lawn requires. And unlike artificial grass or gravel, grass sequesters carbon, and if it isn't treated with pesticides provides habitat for a surprising number of invertebrates as well as the birds that feed on them. There's also been an alarming rush towards ripping out mature landscaping and replacing it was succulents, many of which are surprisingly toxic. You can read more here. Plants like pencil cactus, agave, and sego palm are popular because they are strikingly beautiful, but they can cause serious allergic reactions in humans and pets. A single sego palm seed can kill a large dog or a child.  


One of the most important contributions to the environment we can all make is eliminating toxic pesticides from our homes and gardens. Poison Free Malibu is working tirelessly to eliminate the deadliest wildlife-killing rodenticides—unfortunately found all over Malibu in bait boxes, but we can all help by excluding rodents, instead of poisoning them and making sure accidental food sources like garbage cans and pet food are cleaned up and secure. 

Eliminating herbicides like Roundup and toxic insecticides also helps every part of the local ecosystem, from soil organisms to bees and butterflies to humans and pets. Visit Poison Free Malibu's website for information and practical advice.



Birds depend on insects—especially caterpillars—as high-protein food for their young. If humans are willing to put up with a few creepy crawlers they can help hundreds of backyard species thrive.


The pocket gopher is probably the number one reason Malibu homeowners resort to outdoor use of rodenticides. And because this small rodent is the bottom of the food chain, poisoning this wee beastie causes secondary poisoning to every species that depends on rodents for prey, including owls, hawks, bobcats, raccoons, weasels, badgers, coyotes, mountain lions and domestic cats and dogs.


In a healthy ecosystem gophers are kept in check by all the species currently being poisoned by rodenticide overuse, like this benign gopher snake. 

Topanga recently became a National Wildlife Federation certified Wildlife Friendly Community. That's something Malibu could do, too. Leaving or creating  "wild" areas, and providing water and bird and butterfly friendly plants help create islands of habitat is even in the urban areas.



At the Malibu Post we have resident rabbits like this one, which lives in a brushy corner of the backyard, in addition to gray squirrels, dusky-footed wood rats, gophers, voles, and field mice. Wild visitors include a veracious gopher-eating short-tailed weasel, a family of bobcats, the entire east Point Dume coyote clan, and assorted raccoons, skunks, gray foxes and possums. We love all of our creatures, even the skunks, but realize that not everyone enjoys having backyard wildlife. Secure fencing that extends a couple of feet under ground is the best way to discourage visitors. Most species can fit through astonishingly small gaps in or under fencing. It's a good idea to check the fence line regularly, and make sure trees, bushes, or vines aren't creating a wildlife highway. One place no one wants wildlife is in the house. Sealing openings like the gaps around pipes and making sure all vents are screened with hardware cloth can help. 



Building or buying a bird box is a great way to help native birds We got this blue bird box last Christmas and were rewarded with not one but two successful batches of bluebirds during spring and summer. Location is extremely important for a bird box success story. This one was placed about six feet up the trunk of a liquidamber tree that offered the parent birds shelter and secure perching and vantage points as well as afternoon shade to keep the nestlings from overheating. If you're sure you live in a location where rodenticides aren't being used a raptor box can be a great addition to the garden.


Learning to live with wildlife, even the species we aren't always comfortable with, like coyotes, is a huge piece of the local environmental equation. Coyotes primarily prey on rodents like ground squirrels, gophers and wood rats and help control them. Learn more about coyote proof fencing and other coexistence techniques at coyoteproject.org. The Mountain Lion Foundation offers advice on dealing with Malibu's biggest urban predator.

You don't need a garden to tend to nature. All of the non- profits mentioned here depend on contributions. At Poison Free Malibu those donations help pay for ordinary but essential needs like printing and mailing. At Project Coyote  they help fund co-existance workshops and education outreach. Donations to the National Wildlife Federation can be earmarked to help save Malibu's mountain lions and build the Liberty Canyon Wildlife Overpass.

All Malibu residents are stewards of our natural resources, and we are blessed to have a national park as our backyard and the ocean at our door. Every canyon, every creek, every road leads to the sea. Malibu has a tradition of valuing those resources and our newly installed city council has vowed to protect them, but it's up to all of us to work together towards that goal.



Malibu residents often have the mountains or the ocean as their backyard. It's an extra responsibility for all of us but also one the great joys of living here. This remarkable group of sea birds includes two California brown pelicans, an adult Western gull, a juvenile Western gull and two ring-billed gulled, and they aren't out in the middle of some lonely stretch of unspoiled seashore. Instead, they're right here:


The fact that we still do have so much wildlife is a testament to our passionate conservation activists, who will continue to fight for the environment no matter what the odds.


There is still time to plant the seeds of tomorrow. For now, let's just enjoy the coming of the rain and the season of peace and joy and hope.


In the garden of my heart, the flowers of peace bloom beautifully.

A Moment for Reflection




Even in an ordinary year it's easy to get bogged down in exhausting negativity of election season. This year, according to the Washington Post, 52 percent of U.S. adults find the presidential election "a very or significant source of stress." Considering the circumstances, the only surprise is that the number isn't higher. In addition, Californians face a monstrous ballot with 17 initiatives, and Malibu residents get an extra dose of stress from a local city council election that has turned brutal in its final days. Here at The Malibu Post we had as much as we could take on all fronts, so we slipped away for an hour to an island of tranquility in a hectic world. 

Not that it is exactly always sane. A famous musician doing an interview adds an element of the surreal, but I've also encountered wedding parties, movie crews, nudists, picnicking Goth girls, scuba divers, rock climbers, helicopters rescuing rock climbers, and once even a giraffe (it was there for a European TV commercial shoot, and not a hallucination brought on by sleep deprivation or sunstroke).



Even with all the human activity there is still space for wild things at Point Dume Nature Reserve. Right now, the giant coreopsis is just beginning to sprout. Thanks to the first rain of the season, emerald green emerging from seemingly dead stalks overnight. Within a month or so the first golden flowers will appear. It reminds me of the magician's trick involving sticks bursting into bloom with silk flowers.  


The coyote brush is already in bloom. Its thistledown flowers seem to glow with their own light as they the catch the late sun.


The sandy path reveals the passage of many feet, but I meet no one.


Sea lions laze in the sun o
n the rocks below the trail.


Their contentment is contagious.


From here, the path winds around the edge of the Point.

Past Pirate's Cove...

Where dolphins swim in water as blue as Kashmir sapphires...


And up to the top of the southernmost point in Malibu, where 
the Chumash people once watched the sea and the Pacific Ocean stretches all the way to Antartica.

Beachgoers gather on the shore as the sun begins to set.


The wind makes patterns on the sand.


A surfer catches a wave.


And the sun sets. The world didn't end today. It probably won't end November 8, no matter what the outcome of the elections. And here in Malibu it will still be another day in paradise.

Bluebirds and Happiness


Bluebirds are a traditional sign of good fortune in several cultures, but the Bluebird of Happiness seems to originate in Belgian symbolist writer Maurice Maeterlinck's 1908 play The Blue Bird. And like the children in the play, we found happiness—and bluebirds—right in our own backyard this spring here at The Malibu Post. While its fate is still in the balance, the Western bluebird, Sialia Mexicanaappears to be on its way to a happy ending. This beautiful bird came close to extinction in the 20th century, due to DDT, habitat loss, and competition from non-native species like the house sparrow. Bluebirds are making a recovery, thanks to passionate advocates who are providing a voice for the species and are seeking to reintroduce it to areas—like Malibu—where bluebirds have been missing for decades.


Encouraged by the presence of a bluebird family at our birdbath last year, we purchased a bluebird box this spring and installed it in a liquidamber tree. The first visitor to the box was an oak titmouse, but apparently the box didn't meet his requirements. A week later, a pair of bluebirds moved in.


Nest building commenced at once. This is the male, bringing grass and what looked like palm tree fibers into the box. Both Eastern and Western bluebirds need cavities like hollow trees to successfully nest. In the Santa Monica Mountains, they compete with wrens, tree swallows, and the oak titmouse, as well as non-native sparrows, for nesting space. The right kind of real estate can be scare. Nest boxes offer a good alternative, but they have to be the right kind of box. Wrens aren't particular—they'll nest in almost anything. But bluebirds need a tall narrow box for safety. It should have good ventilation and an entry hole that is the right size for the species.  It's important to avoid the kind of bird boxes that have a built-in perch. Predators like crows and squirrels can use a perch to gain access to the nestlings. It is important to place the bird house in a safe location where cats, raccoons and rats don't have access, and also to monitor the box to make sure house sparrows don't move in before the native birds have a chance. 
 


The industrious female kept showing up with astonishing amounts of building material. Here she is with a beak full of pine needles. 


Here she is again, carting in a bunch of oxalis stems and a dead leaf.


Finally, the nest was finished and the business of laying eggs and incubating them begun. The bluebirds rapidly adapted to their human and canine neighbors. We often saw the female watching us from the entrance of the nest, but she never seemed to mind when we walked past. 


The male brought food to his mate and kept watch from the top of the tree for potential hazards.


The neighborhood fox squirrel was the biggest threat. 


He lurked like a kind of rodent Godzilla, but never managed to break into the nest.  Here's how he looked to the bluebirds. Not remotely cute and furry.



Our looney dog took no notice of the birds until the eggs hatched and the chicks grew big enough to make noise. Then she became obsessed and had to be temporarily vanquished from that part of the garden. Cats and dogs can have a catastrophic impact on wild birds and we didn't want to take any chances.



Once the eggs hatched, the nest became a hive of activity, with both parents swooping in and out all day long with insects for their brood. 


Here's mama bird with a fine fat caterpillar. Bluebirds depend on open areas for foraging and often seek out lawns—a reminder of why it is important to avoid toxic pesticides and lawn chemicals. Ecologists warn that homeowners
 who replace their lawn with gravel or artificial grass in a well-intensioned effort to conserve water may actually be removing essential bird habitat, inadvertently creating wildlife wastelands. Replacing lawns with native plants, or adopting a turf-management program that conserves water through the use of mulch and other organic methods are bird-friendly options.


That caterpillar went straight into the open beak of a hungry nestling. 


As the chicks neared fledging day they became increasingly noisy and active, peering out of their front door and chattering to each other. 


We never saw the young ones fledge. One day, the nest was a hive of activity; the next, it was empty. I caught one last glimpse of mama bluebird on her favorite perch overlooking the garden, and then they were gone. The garden seems strangely empty without them.
