Brent left for vacation in Hawaii at about the same time that I returned from vacation in Oregon and Washington. Since I told him to stop sending me so many pointless pictures prior to my vacation, he is now sending even more. I might have gotten more pictures of his vacation than I got of mine. Although I would like to see Hawaii for the horticultural aspects, I am not otherwise impressed by what little I know about it. Perhaps I would get a better impression of it without so many of Brent’s pointless pictures. These are a few of the lesser pointless pictures, without the selfies.
Canary Island date palm is the largest local palm. Pygmy date palm, Phoenix roebelenii, although a species of the same genus, is one of the more diminutive palms. It might take many years to grow ten feet tall, and may never get twice as tall. Its pinnately compound leaves are only about two to four feet long. Thin leaflets are about five to ten inches long.
Such compact stature is a distinct advantage for some situations. With sufficient sunlight, pygmy date palm is a delightful houseplant. It is also appealing within atriums and cozily compact gardens. For those who appreciate the aesthetics but not the large size of most palms, pygmy date palm is a practical option. It actually resembles a common date palm.
Like all date palms, a pygmy date palm surrounds its single terminal bud with nasty long spines, which are specialized proximal leaflets. These spines are painful to interact with while grooming and pruning deteriorated old leaves and floral trusses back to their trunk. Unlike most other palms, mature pygmy date palms are not very conducive to relocation.
Palms seem to exemplify the culture of California. However, only the California fan palm, which is also the desert fan palm, is native. All others are exotic. With its dwarf palmetto, Oklahoma has as many native palms as California. Furthermore, the California fan palm is only endemic within remote riparian ecosystems of the Colorado and Mojave Deserts.
Common date palms were likely the first of the many exotic palms in California. Spanish Missionaries imported them for date production during the Eighteenth Century. Although initially utilitarian rather than decorative, recycled trees from displaced orchards became popular for larger landscapes. Potentially messy fruit is minimal without male pollinators.
Long before urbanization displaced date orchards, many other palms came to California merely because of their visual appeal. Some are large enough to be shade trees. Others can provide shade in groups. Many develop elegant trunks or sculptural form. Some stay relatively low or shrubby. All innately provide famously and luxuriantly evergreen foliage.
Palms are most certainly appealing within appropriate situations. They are very different from other trees though. Like arborescent yuccas and cordylines, palms are ‘herbaceous trees’. Unlike yuccas and cordylines, and with very few exceptions, palms do not branch. Nor do their trunks continue to expand in width as they continue to grow in height above.
Palms consequently spend their first few years widening their bases at ground level. Big palms, such as Canary Island date palm, likely require many years. Once their bases are adequate, developing palms ‘launch’ into vertical growth. Although palms do not branch, a few, such as Mediterranean fan palm, develop multiple trunks from their primary bases.
Once palms launch, they grow only upward. They lean only to avoid shade, or if pushed by wind. It is impossible to direct their bulky but singular terminal buds around obstacles, such as utility cables. It is also impossible to contain their shade as they get high enough to shade adjacent areas instead. Many palms are spiny, so are difficult to prune properly, even while young and within reach.
While Mexican fan palms and Canary Island date palms dominated the palm fad in California during the Victorian period, the queen palm, Syagrus romanzoffiana, was still relatively uncommon. Since then, selective breeding has improved their foliar color and density. They are now the most popular of palms.
Modern queen palms grow a bit faster than their Victorian ancestors to about thirty feet tall, and then grow somewhat slower for another ten to even twenty feet. Their long and arching feather (pinnately compound) leaves are quite billowy. The elegant trunks are generally slender, but often develop constrictions or bulges from fluctuations of irrigation or nutrient availability. The abundant fruit can be messy.
California has no more native palms than Oklahoma has with the diminutive dwarf palmetto. The stately California fan palm, which is also known as the desert fan palm, inhabits warm desert regions in southern California. It is what put the ‘Palm’ in ‘Palm Springs’. However, because it likes heat and minimal humidity, it is not so happy away from deserts. The very tall and lean Mexican fan palm is closely related to the comparably stout California fan palm, but is so happy in local climates that it naturalizes and can be invasive.
The queen palm has a leaner trunk, and a broader and more billowy canopy. It rarely self sows, but is so overly popular that it very often gets planted in bad situation where it does not have room to grow. Unlike fan palms that have rounded palmate leaves that radiate outward from the ends of bare petioles (leaf stalks), the queen palm is a ‘feather’ palm, with pinnately compound leaves comprised of narrow leaflets arranged along stiff midribs.
The massive Canary Island date palm is another feather palm, with a broad canopy and bulky trunk. Like Mexican fan palm, it often self sows, so gets into some weird situations. The foliage is so thick that is commonly becomes infested with rats and pigeons. Female trees produce messy fruit that keeps rats and pigeons well fed.
Whether they get planted intentionally or simply appear in the landscape, the main problem with all these and other large palms, is the expense of maintenance, since they can only be maintained by professional arborists who know how to climb such large branchless trees. Without regular grooming, fan palms that are so often allowed to retain long beards of old leaves become fire hazards, and have the potential to drop dangerously heavy sections of their beards without warning. Removal of old deteriorating leaves from the huge canopies of Canary Island date palms is quite an chore!
There are few small palms, like windmill palm and Mediterranean fan palm, that are more proportionate to compact gardens. Windmill palm has a strikingly shaggy trunk and a compact canopy that is easy to groom before it grows beyond reach. Mediterranean fan palm has multiple trunks that grow so slowly that it takes many decades for them to grow beyond reach. Nasty sharp thorns on their petioles make pruning difficult but not impossible.
Selection of a palm that is appropriate to a particular situation is just as important to limiting serious long term problems as the selection of any other tree is.
Most palm enthusiasts believe that the distinguished Bismarck palm, Bismarckia nobilis, is rare because it does not like local climates. It can be damaged by frost in winter, and prefers warmer weather in summer. Another concern is that they get too broad for compact urban gardens, since their shady foliar canopies can get more than twenty feet wide. However, a few seemingly happy specimens are sometimes seen about town.
Foliage of this rare palm is strikingly silvery gray. Green Bismarck palms are even more scarce, both because they are less tolerant to frost, and because they are not so striking. The big and rather rounded leaves are more than six feet wide, and maybe up to eight feet wide, on petioles (stalks) about six to eight feet long!
It was a mistake to tell Brent to not send so many pointless pictures to my telephone. He now sends more than ever. My telephone gets too clogged with them to take ‘important’ messages, as if any are important. Brent gets annoyed if my telephone us unable to take more, or if I delete messages without opening them. Really though, I do not have time to see all of his pointless pictures and videos, and I should be able to accept messages from others also. If and when Brent actually sends something important, it is typically of such inferior quality that is is useless to me. #5 is an example of that. I should get some of my own pictures to share next week. I want to show off Rhody’s Roadie. Also, we ‘should’ be leaving for Washington on Wednesday.
1. This is nothing new, although it is a more recent picture of Brent’s back garden. Brent does like to show it off. It looks like a garage sale with a tiny kangaroo in the middle of it.
2. Less clutter in this direction reveals the office with the roof deck above. That is where I camp out when I go to Southern California. That is some lush scenery to wake up with.
3. Three of seven queen palms live across the garden from my campsite on the roof. The famous ‘Hollywood’ sign is in the distance behind them. Four more queens are out front.
4. This is not the four queens out front. It is four canopies on two trees, elsewhere in the neighborhood. Branched palms are very rare. (Doum palm is not evident in the region.)
5. Goodness! This is the most significant of these Six, but is of such bad quality. Brent is an idiot! It is one of only a few surviving Olympic Oaks of the 1936 Olympics in Berlin. It was awarded to Cornelius Johnson, in conjunction with a Gold Medal, by Adolph Hitler, who would not acknowledge victory by anyone of African Descent. Brent was protecting the tree from developers who want it removed, but now wants to designate it as historic.
6. See if you can make sense of this one. It is no music video. The original was even a bit weirder. The Mexican fan palm is a Memorial Tree of Brent’s older brother Brian Green.
This Six on Saturday did not go as planned. I intended to finally share six pictures of the esperanza and poinciana (pride of Barbados) seed from Crazy Green Thumbs, since they were sown shortly before I shared more of Brent’s pointless pictures last week. However, the file of those pictures was somehow deleted! It is too dark to get a picture now. When I get a picture later, it will show only flats of unseen seed! Since reminding Brent to NOT send more pointless pictures, he responded by sending a profusion of pointless pictures! However, if I can not share the six pictures that I very much wanted to share this week, I will most certainly not share six more pointless pictures that I do not want to share. So, I ultimately decided to share six pictures of an exemplary Mediterranean or European fan palm, Chamaerops humilis, that we relocated more than two weeks ago. However, since I had not planned to share these pictures just yet, I had neither procured a picture of the palm at its new home, nor copied a picture of it prior to departure from its former home.
1. From beginning to end, and even after the intensive grooming of the trunk, only three of these many healthy fronds got pruned away, and only because they hung too low. For most palms, I prefer to remove most foliage for transplant. So far, this one sustains it all. This is the view of the top of the canopy as the dug tree was laying in back of the pickup.
2. Female specimens have fewer and more pliable teeth on their petioles than the males. This was one of the most tame of females I have ever engaged. I had expected far worse.
3. Only a few aborted berries were observed. Since this species in unpopular here, it may lack a male pollinator. However, it has potential to sneakily provide its own male bloom.
4. Gads! I almost never see this palm pruned and groomed properly. Petioles should get cut below the thorns and as closely to the trunk as possible. These long stubs are thorny.
5. The upper left quadrant of this picture demonstrates what this trunk should look like, after the thorny petiole stubs were cut away. It looks like Lumpy, the son of Chewbacca.
6. Here, it looks like Doctor Lecter of ‘Silence of the Lambs’, strapped into a dolly. It was much easier to handle after grooming, but still weighs about a hundred and fifty pounds. This species typically develops a few curving trunks. Such a straight single trunk is rare.
Esperanza and poinciana (pride of Barbados) from Crazy Green Thumbs will be delayed again. I still have not sown the seed, and when I do, I will likely delay posting pictures of them until I have exhausted all of these pointless pictures that Brent sends to me. There may be six more for next week after these six. Fortunately, the few that arrived since this purging began are not very interesting, so need not be shared. These six pictures arrived at various times through the past few months; and I did not document dates for them. It would be difficult to identify their chronology without inquiring with Brent, and without familiarity with potentially observable seasonal indicators of the particular climate. I am less than three hundred fifty miles away, but in an entirely different climate and region.
1. Baby queen palm, Chamaedorea plumosa, which is not princess palm, Dictyosperma album, is related to popular bamboo palm, Chamaedorea seifrizii. Brent got this for me.
2. Of all of Brent’s landscapes, this might be my favorite. The formality is rad. However, these illuminated Canary Island date palms, Phoenix canariensis, must be embarrassed.
3. Mexican fan palm, Washingtonia robusta, is a most common palm of the Los Angeles region. Although palms are popularly informal, some might be formal and symmetrical.
4. Mexican fan palm dominate the view. Kentia palm, Howea forsteriana, California fan palm, Washingtonia filifera, and queen palm, Arecastrum romanzoffianum, got in too.
5. Brent likes to show off his palms. They are more visible from next door than from the garden they inhabit. The Mexican fan palm is a Memorial Tree for Brent’s brother Brian.
6. Coons! The arborist who pruned this Mexican fan palm returned to finish shaving the trunk, but found that a pair of coons who inhabited the beard were not ready to relocate.
Not all palms are trees. Some lack trunks, so develop more as shrubbery. Some develop many slender stems, like bamboo. The thin canes of most rattan palms sprawl onto other vegetation for support, as vines. Mediterranean fan palm, Chamaerops humilis, develops multiple stout trunks, but grows so slowly that it can function as big sculptural shrubbery.
Old trunks can eventually get as high as twenty feet, and generally lean randomly. If they get too tall, smaller and more vigorous trunks can replace them. (An arborist can remove the bulky and thorny old trunks.) New trunks develop from basal pups, which can can get too densely foliated without occasional thinning. Removal of such pups might be difficult.
Mature trunks might be as wide as ten inches, with dense coats of basal petiole fiber and thorny petiole stubs. Thorough grooming can eliminate the stubs. However, petioles that suspend the evergreen palmate leaves are outfitted with the same wickedly sharp teeth. Leaves are about two feet wide. Atlas Mountain palm, Chamaerops humilis var.(iety) argentea has strikingly silvery foliage, and grows even slower.
