Six on Saturday: Redwoods

 

Both coastal and giant redwoods, are the most excellent trees. The giant redwoods are endemic to isolated colonies in the Sierra Nevada. The coastal redwoods are endemic to the coastal region from the Oregon Border to San Luis Obispo County, which happens to include this region.

Coastal redwoods are so awesome that even the dead stumps from trees harvested a century ago are awesome. Most of the stumps in this region have been charred by forest fires. Yet, even after a century, they are still quite solid. They decay very slowly, which is why their timber is such a popular and important building material. Because the stumps are so big and would be difficult to get rid of, not many of us even try.

1. Compared to some of the tacky garden art that some people pay significant money for, this old redwood stump is strikingly sculptural. It stands so proudly out on this knoll on the edge of a small creek just above where it flows into Bean Creek. It is difficult to see in this picture, but a landscaper tried to obscure this stump with potato vine. Only a bit of twiggy growth can be seen at the top of the stump. The rest of the vine is now overwhelming the adjacent dogwood above. The trunk of the dogwood is to the right. Coastal redwood forests are innately shady. The potato vine is not very happy there. Even if it were happy, and were able to obscure the stump, would it really be an improvement?P80142. These two bigger stumps are just a short distance uphill and across the small creek. Old stumps are more often single, but surrounded by multiple trunks that emerged from the roots. Because almost all of the trees here had been harvested about a century ago, there are now many more secondary trunks per area than there would naturally be. It is not much of a problem yet, but these trunks will likely become more crowded as they mature.P8014+3. These are the same two stumps from the other side. This trunk coming up from within is likely from the same original root system. All trunks that develop from the same root system are genetically identical, so they look very similar from a distance. Some genetically identical groves can be quite broad, and include many trunks.P80714++4. This small coastal redwood trunk is not happy about the fence that is nailed to it.P80714+++5. This is more what you expect coastal redwoods to look like. It is impossible to determine from this picture if these trunks are genetically identical secondary trees that emerged from the same root system, but their proximity to each other suggests that they likely are.P80714++++6. This epiphyllum is the flower that I promised to those who expressed a concern than my Six on Saturday lacked adequate bloom. I shared a picture of this same epiphyllum earlier, but it has continued to bloom.P80714+++++

Blue Plumbago

70712The delightfully clear sky blue flowers of blue plumbago, Plumbago auriculata, seem like they belong with colorful annuals or in a tailored border of colorfully blooming perennials. However, the rampant canes of mature plants are really best in the background where they have room to grow wild. The canes do not climb like vines, but can flop over other shrubbery as high as fifteen feet.

Rounded trusses of small blue flowers begin to bloom sporadically by the end of spring, and continue to bloom in phases until late summer. Supposedly, each subsequent phase should be a bit more profuse than the previous; but not all plants are aware of this. They might bloom best in mid summer, and less profusely later. ‘Alba’ blooms white. Pale foliage indicates a need for fertilizer.

Blue plumbago is not as easy to work with as it seems to be. Once established, it can grow like a weed, and really seems to take care of itself, and it is probably better to allow it to do so. It does not like to be shorn into hedges or geometric shapes as it so often is. Shearing ruins the natural form, eliminates most of the outer canes that provide bloom, and exposes sparse interior growth.

Be Tactful With Garden Art

70712thumbSaint Francis is actually the patron saint of animals. Saint Fiacre is the real patron saint of gardening. However, statues of Saint Francis, usually accompanied by birds, and sometimes by a deer, are popular in home gardens. Has anyone ever seen even a single statue of Saint Fiacre? Statues of Snow White are more common; but her only experience with horticulture was one bad apple.

There is good garden statuary, and there is bad garden statuary. Some of the bad can be exceptionally so. It is one of the many things that back yards are for. Not much offends neighbors like a bronzed lawn mower on a pedestal in the middle of a paved front yard. Yes, it has happened. Perhaps there is beauty in the diversity of unique artistic expression. Saint Francis can not do it all.

Garden statuary and other forms of garden art work like any other household art. For many of us, it merely provide dramatic form, and perhaps color that is more permanent than flowers are. For others, there is a certain degree of self expression associated with the careful selection and display of garden art. Some of us take this even further by creating our own distinctive garden art.

Fountains and wind chimes are often incorporated into gardens to detract from less pleasant ambient sound, or simply because they sound nice. A loud fountain probably would not obscure the sound of a freeway in the neighborhood; but the sound of even a modest fountain might be adequately distracting. Wind chimes are as variable as the delicate to bold breezes that operate them.

As far as garden art is concerned, fountains and wind chimes need more maintenance than simple inactive sculpture. Chimes might sometimes need to be tied up or taken down if they get too noisy in windy weather. They can get tangled or so weathered that the strings that suspend the chimes need to be replaced. When this happens, it might be easier to simply get new wind chimes.

Fountains are more involved. Water must be added to replace what evaporates. Mineral deposits must be cleaned from some surfaces. Any aquatic plants need to be groomed like other plants in the garden. For larger fountains, fish might be employed to control mosquitoes. However, fish might attract raccoons! Small fountains with neither fish nor plants might be kept clear with bleach. So, even though garden art is not as dynamic as living and growing plants are, some of it requires significant maintenance anyway.

Horridculture – Rose Colored Glasses

P80711

This article reminded me of a sore subject from back in about 1986 that continues today: https://wordpress.com/read/blogs/7890212/posts/4888 You should probably take a look at it before you continue.

Back when my colleague and I were roommates in the dorms at Cal Poly in San Luis Obispo, we noticed how badly the photographs in bare root catalogs had been modified to enhance color. Years before modern digital editing, colored film was cut out to any desired shape and placed over a photograph to produce a new photograph with enhanced color. We looked at pictures of flowering crabapples with canopies that were entirely bright pink, including the stems, leaves and everything associated with the canopy of the tree. We could easily see the outline of the bright pink film that had been placed over the original photograph. It was done with blue fescue, hydrangeas, azaleas, callas and really just about anything that could benefit from a bit of enhanced color.

It certainly did not dissuade us from our interest in the plants that had been photographically enhanced. We liked them anyway. The poor quality of the enhancements that would be laughable by modern standards seemed to be more acceptable back then; like the idealistic pictures of the food available from popular fast food establishments. I mean, we all know that the food does not look like ‘that’ but it probably tastes like ‘that’ looks.

Three decades later, modern technology of digital editing of photographs (if they are still known as ‘photographs’) has improved the technique of color enhancement significantly. Most pictures in catalogs are now enhanced to some degree, not to be deceptive, but to eliminate minor glitches that might distract from the rest of the image, and perhaps to enhance color that is slightly compromised by the exposure at the time the picture was taken.

But of course, there are some images that are blatantly inaccurate and deceptive.

My colleague down south tells me that pink pampas grass can be about as peachy pink as cantaloupe is. It could possibly be more pink in other regions. I have never seen it more than simple pinkish tan here. I know of no one who has confirmed that it can be as bright cotton-candy pink as it is in the picture above. Is it inaccurate and deceptive? I do not know. I do not really care. If I wanted pink pampas grass, I would purchase it anyway, and just try to not be too disappointed when it blooms tan.P80711+This picture above is certainly interesting as well. It is such an appealing color. What is more interesting it that it is the exact same picture as the picture on top, but is merely a different color. I have never heard of a pampas grass doing that! It must be quite common though. Online, there are a few pictures of other pampas grass doing the exact same thing. These two below, for example, are the exact same picture in two different colors, and with slightly different proportional modification.P80711++P80711+++As amusing as these pictures are, they are not as downright KRAZY as the rainbow rose in the article that I posted a link to above is. It is certainly worth taking a look at.

Coreopsis

80718It is a common theme. Coreopsis was a much simpler group of only a few specie and cultivars in the 1980s. There are now too many hybrids and cultivars to keep track of. They have been bred so extensively that they do not produce viable seed like the old fashioned types that can self sow so nicely, and were more closely related to the unimproved specie that would be found in the wild.

Breeding did more than expand the range of floral color and form. It combined the more impressive flowers with the resiliency of the toughest of perennial specie. Because they are sterile, some of the modern hybrids may not need to be deadheaded like more traditional types. Although tougher modern hybrids can capitalize on the sustainability fad, they can not proliferate and naturalize.

Coreopsis blooms in summer and autumn. The small daisy like flowers can bloom yellow, orange, red or pink, but traditional bright yellow is still the favorite color. Most cultivars are less than two feet tall and wide. A few can get nearly twice as tall. The most compact cultivars are only about half a foot tall. Coreopsis wants good sun exposure, and will bloom less and likely mildew if shaded.

Saving Seed For Next Season

80718thumbThe gardens with the most flowers need the most deadheading. This involves the removal of deteriorating flowers and any developing fruiting structures and seed associated with them so that they do not divert resources from subsequent bloom or vegetative growth. Old flowers that do not produce seed because they are sterile or lack pollinators might get deadheaded too if unsightly.

Deadheading is not for everyone though. Flowers up in trees, big shrubbery or large vines are obviously out of reach. Many annuals, like alyssum and nasturtium, produce far too many flowers to be deadheaded. Most plants bloom and disperse seed without bothering anyone, or even getting noticed. Bougainvillea blooms too flamboyantly to miss, but then sheds neatly without any help.

Bougainvillea does not set seed anyway. The insects that naturally pollinate it within its native range in the Amazon River Basin probably do not live here. Yuccas that live far from their native range likewise lack the specific yucca moth that they rely on for pollination, although some get pollinated by accident. Big yucca stalks get deadheaded just because they are not appealing after bloom.

What is more fun than what gets deadhead is what does not get deadhead. The alyssum and nasturtium mentioned earlier naturally naturalize where they get watered. They toss so many seed around that they can replace themselves as readily as the old plants die out. California poppy, cosmos, calendula, campion, and many other annuals as well as a few perennials, can do the same.

Besides that, there are all sorts of seed that can be collected from old flowers for the following season. Each variety of flower finishes in its own season. Each variety likewise gets sown in its own season. It is not necessary to leave all fading flowers if only a few can provide enough seed for later. It is important to remember that hybridized and some overly bred cultivars do not produce viable seed, and that subsequent generations of the fancier varieties will revert to be more similar to their simpler ancestral parents.

Palm Treevia

P80708

This is a quick trivia question.

Which of these three states has the most native genera of palm?

1. California

2. Hawaii

3. Oklahoma

4. None of the above

P80708+

This is not a trick question. Notice that it asks about genera rather than species.

1. California is home to many exotic specie and genera of palm; but only ONE is native. The California fan palm, Washingtonia filifera, which is also known as the desert fan palm, lives in isolated groves out in the Mojave Desert. https://tonytomeo.wordpress.com/2018/06/30/oasis/ Because it prefers hot and arid desert climates, and does not like to be watered too generously through summer, it is now a very unpopular palm for landscapes.

2. Hawaii, is populated by many more exotic species and genera of palm than California is, but only species of the ONE genera of Pritchardia are native. Many of the exotic genera were imported by ancient Polynesians to produce food. Others were imported later for landscaping.

3. Oklahoma is the sort of place where only a few of the toughest of exotic palms can survive outside. Yet, McCurtain County, in the very southeastern corner of Oklahoma, is home to ONE very rare but nonetheless native variety of dwarf palmetto, Sabal minor.

4. ‘None of the above’ is the correct answer to the question because none of the other choices above have any more native genera than any of the others.

So, although Hawaii really does have more native species of palm, it has no more native genera than California or even Oklahoma. Each of these three states has exactly ONE native genus of palm.

I am sorry that I have no good pictures of any of these palms. All three of these pictures were obtained online. I have experience with neither the dwarf palmetto of Oklahoma, nor any of the species of Pritchardia of Hawaii. However, the California fan palm happens to be my all time favorite palm, even though it is not very happy here. It is such a stately palm, and those grown from the same seed batches are uniform enough for formal plantings. They are the palms that flank the famous Palm Driveway of the Winchester House in San Jose, as they were popular for flanking driveways and roadways in California and Arizona during the Victorian period. I did happen to see California fan palm in the wild outside of Palm Springs while in school in the late 1980s and can tell you that they are spectacular in their native habitat.

P80708++

Note: The elderly and deteriorating California fan palms that flanked the Palm Drive of the Winchester House have been replaced with palms that are hybrids of California fan palm, Washingtonia filifera, and Mexican fan palm, Washingtonia robusta. They are more tolerant to the irrigation of the landscape around them.

More Spontaneous Limb Failure

P80707KP80707K+(This was copied and modified from the Facebook page of Felton League.)

Warm and humid weather is an uncomfortable change for an otherwise mild summer. It also causes spontaneous limb failure among trees, particular those in riparian areas or irrigated landscapes. What sounded like muffled firecrackers was the (slow but steady) fracturing of another cottonwood limb in Felton Covered Bridge Park. (Another incident of spontaneous limb failure was mentioned a few days ago.) (https://tonytomeo.wordpress.com/2018/07/01/spontaneous-limb-failure/) This one was over the picnic area adjacent to the playground. The fallen portion of the limb was less than a foot in diameter, although it was slighter wider than a foot wide where the fracture originated. It fell onto the middle of a group of picnic tables, with the fractured proximal end remaining suspended and attached to the originating tree. Because it remained attached and fractured slowly, the limb did not fall with enough inertia to damage the picnic tables. It was removed very efficiently.P80707K++(continued)

Cottonwood, sweetgum, coast live oak, valley oak, Chinese elm, California bay, California sycamore, willow and various eucalypti are particularly susceptible to spontaneous limb failure. The oaks and eucalypti are particularly dangerous. Oak limbs are extremely heavy, and tend to break away cleanly and suddenly rather than fall slowly while still attached. Eucalypti limbs likewise break away cleanly, and then fall from great heights without many lower limbs to slow them down. As they start to fracture, Chinese elm and willow limbs might stay attached to the main trunks or the larger limbs from which they originate, which might slow them down somewhat.

Sadly, spontaneous limb failure does more than damage whatever the falling limbs land on. It can also disfigure the affected trees so severely that they must be removed rather than salvaged.P80707K+++

Six on Saturday: Finally Flowers

 

After posting so many inter pictures of soil, stone, road signs, plumbing, empty wine barrels and mockery of French culture, I suppose I should share some pictures of actual flowers for a change. I mean, this is about gardening after all. Unfortunately though, I do not work with many flowers. The landscapes are designed to be compatible with the surrounding forests, so flowers are minimal. I already shared pictures of most of the best. Some of these are from gardens that I do not work with. I just thought that they were pretty.

1. Avens finished blooming more than a week ago. I just really liked this picture because it is such a nice swirly orange color. Until I found these, I had not seen avens in many years, and did not expect to see it anytime soon. Since featuring it in the gardening column, I have found that others in other regions are quite familiar with it, and this it more popular than I would have guessed. http://www.canyon-news.com/ph-has-ups-and-downs/80473P80707
2. Lobelia is one of the more common warm season annuals. This is not from one of the landscapes that I work with, but looked good enough in a planter box in town for me to get a picture of it. I do not know what variety it is. There are many varieties nowadays that I am not familiar with anyway. Back in the 1980s, bright blue lobelia was popular alternated with white alyssum. I thought it looked rather silly at the time, but would not mind seeing it now. It was such an 80s look.P80707+
3. Pelargonium was in the same planter box as the lobelia. I know neither the species nor the cultivar. Again, it was just too pretty to pass up without getting a picture. It is more diminutive than the sorts of pelargoniums that I am familiar with. The plants are very compact. The variegated leaves and flowers are quite small.P80707++
4. Zonal Geranium happens to be one of my favorite perennials because it was one of my first. Although I grew my first for only a short while when I was very young, I still grow one that I found in a trash pile when I was in junior high school, and another that I found naturalized in a creek near San Martin shortly after I graduated from college. I bring pieces of them everywhere I go. Both are the big and weedy types that are probably very closely related to the straight species. The first one is the very common bright pink with leaves that lack halos. The second is the very common bright orange red with only slight halos on the leaves. Getting back to this remarkably bright red zonal geranium; it is not one of mine. The leaves have only very light halos. The growth seems to be almost as vigorous and weedy as my bright orange red one, but not quite. It is more tame, and more prolific with bloom. The bright red color is prettier too.P80707+++
5. Lithodora looks prettier close up that it really looks in the landscape. It was planted into one of the newer small landscapes, but is not growing very well. I found the name to be amusing because it seems to mean that it smells like a rock. However, someone recently explained to me that the name means that it adores rocks, since it naturally grows in soil that is too rocky for other plants.P80707++++
6. White Hydrangea is a nonconformist among all the hydrangeas that I fertilized to be either pink or blue. So far, the pink ones are still pink, and the blue ones are still blue. The few white ones are always white. http://www.canyon-news.com/ph-has-ups-and-downs/80473P80707+++++

‘Mystic Spires Blue’ Salvia

70705Once it gets started in late spring, ‘Mystic Spires Blue’ salvia has potential to bloom until autumn. It only needs older floral spikes pruned away as they fade (deadheading) to stimulate new bloom. If it gets overworked and lanky without deadheading, it can be cut back in the middle of summer to start a new bloom cycle all over. It can get more than three feet tall and almost three feet broad.

Butterflies and hummingbirds really dig the small rich purplish blue flowers that are tightly packed into the upper foot or so of the floral spikes. These floral spikes tend to lean away from the center of the plant, with the tallest on top leaning collectively in one direction or another. They look like they would be good cut flowers, but they might start to drop their older flowers after only a few days.

The deep green foliage is technically evergreen, but it does not matter. All growth should be cut back to just a few inches above the ground in winter. ‘Mystic Spires Blue’ salvia likes richer soil and a bit more water than what drought tolerant salvias want. Yet, like most salvias, it grows more efficiently as #1 (1 gallon) plants planted as winter ends, than #5. Warm and sunny exposure is best.
