More Palm Silliness

Mexican fan palm, Washingtonia robusta

Mexican fan palm, Washingtonia robusta, is the most familiar palm throughout most of California. It is most typically groomed to remove deteriorated leaves without removing the associated toughly fibrous petiole bases that form a neat lattice-like sweater of stubble around its trunks. Some are groomed to also remove the stubble, leaving a clean shaven and leaner looking trunk. Some are shaven only part way up, with a sweater higher up. Without grooming, or if grooming discontinues, some accumulate beards of deteriorated leaves. Although generally harmless, such beards are combustible and can be infested with rats. On rare occasion, they become dislodged from their trunks and fall. They are dangerously heavy and very messy. This silly looking Mexican fan palm was groomed part way up, and then neglected long enough to accumulate a significant beard. The beard then fell, leaving the bare trunk exposed. Only the few lowest of the old leaves remain below where the beard was. A new beard is now forming above.

Queen palm, Arecastrum romanzoffianum, was an uncommon palm until it suddenly became very popular and almost too common through the 1990s. By that time, selective breeding produced the standardized modern variety, which is a bit greener, fluffier and more vigorous than most old specimens. Although it is a bit more genetically conformative than old specimens, it still exhibits genetic variability. Unless some are cloned by tissue culture, all are grown from seed. Some grow slower, so stay shorter. Some develop unusually plump trunks. Some are unusually floppy. This one is just weird. Its foliar canopy is so strictly narrow that it resembles the locally rare Andean wax palm, Ceroxylon quindiuense. Perhaps it actually is an Andean wax palm! A pindo palm, Butia capitata, lives in the associated front garden, and it is not exactly common.

queen palm, Arecastrum romanzoffianum or Andean wax palm, Ceroxylon quindiuense or something else?

Palm Ignorance

Bismarckia nobilis

Many years ago and before I started writing my gardening column in response to all the horticultural misinformation that I had been observing in the San Jose Mercury News, I heard some of the most idiotic commentary I have ever heard about palms on the radio. I do not remember what radio station it was broadcast from, but it was likely in San Jose. The commentator was expressing his disapproval of the many mature palms that were being incorporated into public landscapes there at the time. He started by stating that, “There are two kinds of palms . . . ” Well, that certainly got my attention. He continued to say, ” . . . the tall skinny kind and the short fat kind.” Wow, I can not forget a comment like that. I knew that he was referring to Mexican fan palm and Canary Island date palm, which were and probably still are the most common palms in San Jose. Also, they were the two species that were so commonly installed into public landscapes at the time. There was no mention of queen palm, windmill palm, Mediterranean fan palm or California fan palm, all of which also inhabit San Jose. Since then, queen palm and the formerly rare pygmy date palm have become more common than they had been. Hesper palm remains rare. I brought three distinct species of bamboo palm from Los Angeles, and would like to bring a few more of the palms that perform well there, even if they do not perform so well here. I happen to be fond of the few types of king palm. I very much want to procure Bismarck palm like this one. Although still uncommon in Los Angeles, it is not completely rare. No one knows how well it performs here because no one has tried it yet.

Six on Saturday: Winter to Spring

Spring is beginning to express itself. Only one of my six thinks that it is still winter. After a mild winter, I expected this sooner.

1. Colocasia gigantea ‘Thailand Giant’ elephant ear is the only one of these six to remain dormant. I still must determine if two will go directly into a landscape or get canned like the other two next week. I actually purchased these corms, but do not feel guilty about it.

2. Alocasia macrorrhiza ‘Borneo Giant’ elephant ear is another guiltless purchase. It has a very similar name and is from a similar region as the ‘Thailand Giant’ elephant ear, but grows from smaller rhizomes rather than fat corms. It is already generating new growth.

3. Musa acuminata ‘Double Mahoi’ banana was one of several items that I brought back from Los Angeles last year. After taking several small pups from it, I gave the original to a neighbor. Then, all the pups seemed to die! Now I am pleased that they are recovering.

4. Actinidia deliciosa, fuzzy kiwifruit cuttings are generating foliage. I hope that they are also generating roots. They are a male pollinator for a female cultivar that grew last year from a single pruning scrap that an associate here neglected to remove from his pickup.

5. Platycerium bifurcatum, staghorn fern looks weird as it extends new foliage. Actually, it always looks weird, which is its primary allure. I am concerned that such fresh foliage can be damaged by cold rain. It likes rain and humidity but in conjunction with warmth.

6. Viburnum tinus, laurustinus is the only floral feature of these six. I am not so keen on it, but am learning to appreciate it because its early spring bloom is popular where harsh weather through winter inhibits other bloom. It is simple white, without any pink blush.

Horridculture (deferred from Wednesday) – Bad Garden Tour

The Jungalow, as I wrote six years ago, is Brent’s home and associated gardens. It is an overgrown mess of lush foliage. I perceive it to be a frivolous waste of very limited space. Everyone else perceives it to be a phenomenally luxuriant urban oasis.

The house next door is more my style. It is a compact and simple home with simple bisymmetric architecture and an even simpler landscape. If Brent had not installed a symmetrical pair of tipu trees at the curb, a symmetrical pair of Tolleson’s weeping junipers flanking the porch and a foundation planting of star jasmine, it would have no landscape at all. It might be my favorite house in the neighborhood. Brent hates it.

More specifically, he hates that it is right next door. He would prefer it to be a bit farther away, so that a home with a landscape that is more compatible with his could be next door instead.

Anyway, sadly, a back bedroom of the house next door that I am so fond of burned a few days ago. Fortunately, Brent was in his office behind his home when it happened. He noticed a red glow and heard a window break. When he investigated, he could see the fire and smoke through the hedge between the backyards, so called 911. A fire crew arrived within only a few minutes to extinguish the fire before it ruined more of the home.

Brent sent this brief and blurry video of the situation shortly after the fire was extinguished. It resembles a hasty video garden tour, but speeds past some of the more interesting features of the garden, including my homeless camp, before turning back to show smoke rising from the house next door. It is a saddening situation for the next door neighbor.

Hard Hat

This is a harsh reminder.

This is why arborists wear hard hats. It is more than eight feet tall. I do not know how much of it extends into the wet sand. Nor do I know how much it weighs. It might have fallen from about twenty-five feet up. I do not know how far the pole saw that it was plucked down with was extended. Even with a hard hat, this would have been potentially very dangerous. I am glad that it is now on the ground, or will be when it falls over.

Nature is naturally hazardous. We try to make some of it safer. We can not eliminate all hazards though. Some, like this one before it fell, are not obviously hazardous. Some are not visible from the ground. As frequently as some hazards are eliminated, others are developing. Trees are always growing and shedding limbs that get shaded out. Old trees are always dying and deteriorating. It never ends.

The alder that dropped this necrotic limb took quite a beating when the creek flooded last winter. Water was higher than this broken limb now stands. Massive trunks of trees that fell upstream floated through here, battering any tree trunks that they encountered, including the trunk of the tree that dropped this limb, which is now at the edge of the water at its current depth. Such pummelling should have dislodged such decayed limbs. Perhaps this limb was not so decayed last winter, and therefore more firmly attached.

The intention of the minor tree work that was done in this area was merely to neaten the scenery a bit. Hazards such as this were not a consideration, since the trees appeared to be reasonably safe, and because they are located on the bank of a creek where no one else goes.

Mycology

I have no idea what fungi this is.

Mycology was a topic that we horticulture students did not study much in school. We learned about some of the more important fungal diseases of vegetation, but that was about all. We could not take the time to study it any more extensively than mycologists could take the time to study horticulture or even botany.

Yet, horticulturists are often expected to know more about mycology than we should be expected to know. Perhaps it is because fungal organisms seem to grow sort of like botanical organisms grow. In ancient history, mycology actually was more closely related to botany, but needed to become a separate discipline as more was learned about each of the two. Perhaps that was at a time when entomology still included arachnids, myriapods and crustaceans. Heck, there was a time when earth, air, water and fire were considered to be the only four primary elements.

I have no idea what this mushroom is. It got my attention because it is so weird. It is such a weird mix of pastel purple, gray and white, with such a distinctly flat top. It was solitary. Not only did I see no others like it, but I noticed no other terrestrial mushrooms of any sort nearby. It appeared amongst blackberry bramble and naturalized English ivy, on the bank of a creek, under bay trees, with bigleaf maples, white alders, red alders and a deceased Douglas fir nearby. The area was quite damp from all the rainy weather this winter. Large and likely old rusty ruddy brown basidiocarps extend from the rotting bases of some of the bay trees. Smaller and likely younger brown and white basidiocarps extend from the rotting trunk of the deceased Douglas fir. All of this is irrelevant, since I still have no idea what this is.

Six on Saturday: Strange Times

Some flowers are blooming strangely this year. Well actually, one bloomed strangely last year, and is now blooming normally. Flowers that prefer more winter chill than they can experience here are blooming quite nicely this year, even after less frost than last winter. I can neither make sense of it all, nor complain about it. I mean, it may be strange, but it is strange in a good way. We added a windmill palm that I mentioned two weeks ago to a landscape. I like palms, especially this palm, but I am not sure that I like them here with the redwoods. Palms are strange with redwoods.

1. Trachycarpus fortunei, windmill palm is strange because it is one of only three palms here. Palms and redwoods should not mix. It remains canned, so will be removed as the unseen angel’s trumpet behind it grows. I featured it two weeks ago, before it came here.

2. Hyacinthus orientalis, hyacinth is not so strange either, but it performs strangely well and reliably with only minor chill. Several have been blooming like this for several years.

3. Bergenia crassifolia, pig squeak is blooming strangely late with a strangely light pink floral color. Otherwise, it blooms a bit better now that a sycamore that shaded it is gone.

4. Ribes sanguineum, red currant is blooming with a strangely light pink floral color too. It is not much more than white, but is not white. All are this same strangely pallid color.

5. Brugmansia X cubensis ‘Charles Grimaldi’ angel’s trumpet did just the opposite. After blooming strangely pallid peachy orange since spring, it now blooms yellow as it should.

6. Helleborus orientalis, Lenten rose is blooming strangely well this year. Typically, only a few bloom like this. Now, many are. This is one of a uniform colony that is likely feral.

Horridculture – Hackers

How could anyone believe that this was appropriate?!

Of the many different types of horticultural professionals, the two most professional and educated are nurserymen and arborists. The two least professional and downright idiotic are maintenance gardeners and arborists. That means that some of the most professional and some of the least professional of horticultural professionals are arborists.

I have been very fortunate to have worded for some of the most professional, most educated and best arborists. However, much of my work as a consulting horticulturist and arborists involved damage that was caused by some of the least professional, least educated and worst of so-called arborists. They ruin the trees that their clients pay them to maintain or repair. It is infuriating.

Someone put a great deal of effort into destroying this formerly healthy tree.

This tree was formerly a nearly exemplary specimen of big cone pine, Pinus coulteri. It was impressively healthy and exhibited no indication of instability. Its only obvious problem was that it developed so many trunks that it would eventually develop structural deficiency. That will not likely be a problem now, since it will not likely survive long enough for such deficiency to develop. Even if it remains healthy enough to grow significantly, it will become too structurally deficient as a result of this recent damage to survive for long.

I can not imagine how anyone, arborist or not, could believe that this was a proper pruning technique. Nor can I imagine how anyone could have put so much effort into so blatantly destroying this formerly healthy tree. Seriously, this involved a lot of work! Every trunk, every major limb, and many minor limbs were cut. Some cuts were made at lateral branches, but many were not. It is not possible for the tree to compartmentalize all of the resulting pruning wounds, which will remain exposed to the weather until the tree succumbs to the resulting decay.

Recovery from such severe damage is impossible.

Escargots

French hors d’oeuvres are somehow among the most bothersome of garden pests within California. They are voracious. They are very prolific. They are sneaky. They are more resilient to attempts to limit their damage than they had been in the past. Furthermore, attempts to limit their damage are less effective than they had been in the past.

Molluscicides, which are the pesticides that are formulated to be toxic to molluscs such as snails, are not nearly as toxic as they had formerly been. Years ago, they were so toxic that they had potential to be dangerous to cats, dogs, wildlife or children. They are safer for everyone now, including the molluscs that they should be toxic for. Some snails succumb after consuming such molluscicides, but some survive.

The progeny of snails who survive consumption of molluscicide are genetically more likely to also survive consumption of the same molluscicide than snails who did not survive to proliferate. Those who do not inherit such genetic resilience do not survive to proliferate. Consequently, each subsequent generation is more resistant to the particular molluscicide than its preceding generation. Although a different molluscicide would be more effective temporarily, a few snails survive it also, to proliferate and repeat the process. It is how they ‘develop resistance’.

Besides, many garden enthusiasts are hesitant to apply molluscicides because of how toxic such pesticides had been in the past, and how, regardless of how much safer they now are, they must still be toxic to some degree in order to be effective.

Lushly landscaped and generously irrigated home gardens are ideal habitats for snails. Vegetation within such landscapes is damp and sheltered, and provides an abundance of sustenance. Skunks, foxes, ducks and other wildlife that eat snails generally avoid or lack access to many urban home gardens. Opossums and raccoons are either uncommon, or more interested in eating fruits, vegetables, trash or dog and cat food.

Litter Problem

It will not DIE!

We have a litter problem. At least three species of Agave continually have litters of pups. We give almost all of the pups away to friends and neighbors, but more constantly appear. I suppose that we could dispose of some, but that is not easy for those of us who enjoy growing vegetation instead of destroying it.

Pups of one Agave continue to appear where the original was relocated from several years ago. Although I do not know what species it is, it is likely my favorite of the three. However, we can not accommodate all these pups! The original is happy with its new situation, but is beginning to generate a few more pups there as well.

Pups of Agave americana, century plant, got canned because we thought that we could eventually find homes for them. Now, and for the past few years, these maturing pups are producing more pups, some of which are emerging from the drainage holes of their cans! The original is happy to be a neighbor of the unidentified Agave, but could generate more pups at any time.

Agave ovatifolia, whale tongue agave, was purchased by the other horticulturist for a specific situation. It was a striking specimen that was worth what was spent on it. However, it began to generate pups almost immediately after installation, and then suddenly and unexpectedly bolted and bloomed. It was disappointing for such an expensive specimen of a monocarpic species. We removed it after bloom, with the intention of replacing it with one of its several maturing pups. Of course, I could not simply dispose of its carcass. I canned it like a dormant perennial, just in case it did something. Well, now it is doing something! It is bolting and blooming from the grave! I expect more pups soon. We really should get all the Agave spayed!

Agave really should be spayed!
