Saint Fiacre Day

P80901KK

Today, September 1, was the Feastday of Saint Fiacre, the Patron Saint of gardeners. I would not have known if I had not earlier seen this very thorough and informative article written by Doctor David Marsh of the Gardens Trust;

https://thegardenstrustblog.wordpress.com/2018/09/01/st-fiacre/

In all my writing, I had mentioned Saint Fiacre only once, and only in regard to garden statuary. I described how Saint Francis, who happens to be the patron saint of animals, is popularly believed to be the patron saint of gardeners because his statue is so popular in gardens, often in conjunction with statues of frolicking animals, but that statues of Saint Fiacre are very rare.

Besides the Feastday of Saint Fiacre, this September 1 also happens to be the first year anniversary of my blog. I have now been posting articles from my weekly gardening column, as well as other elaborations, for an entire year. With the exception of September 2, the day after establishing the blog, I have posted an article daily. Since participating with the Six on Saturday meme, I have been posting two articles on Saturday. There were even a few days in which three articles were posted.

Unfortunately, back in February or March, my weekly gardening column was discontinued from the Silicon Valley Community Newspapers, which was the first newspaper group that I started writing for nearly twenty years ago. Silicon Valley Community Newspapers still has access to the articles, and can use them if they choose to; but I am no longer employed with them. Because I write for several other newspaper groups, I did not want to stop writing my weekly gardening column just yet. I enjoy it too much. I will have been writing it for twenty years in October, but blogging is still new to me.

Different Time Zones

P80901KIf the flower on the left is a four o’clock, is the flower on the right a five o’clock, or perhaps a three o’clock? Is one a.m. and the other p.m.? What about the flower of the same species that I featured twelve hours ago? What about those in another picture that I will share next Saturday?
Of course, only the colors are different; not the name . . . or the time.
What is odd about these two seemingly different flowers is that they are on the same plant. In fact, they are on the same stem, separated only by a few inches.
Four o’clocks can be odd that way. Individual plants typically bloom with exclusively pink, red, white, yellow or orange flowers. The shades and hues of these colors are variable, but are typically homogeneous throughout each entire plant.
Some plants bloom with flowers of one color that are spotted or variably striped with another. Their flowers are not as homogeneous as those that bloom with only one color, so some of their flowers might be uniformly one color or the other, without spots or stripes. Some plants bloom with a few different colors!
Distinctly bright pink (but not light pink) flowers seem to be the most fragrant and the least variable, typically devoid of spotting or striping. They may be more closely related to the wild species, as it would have been found in its natural range in the Andes, prior to breeding for more interesting colors. Perhaps, after enough generations, other four o’clocks would eventually revert to the same characteristically fragrant bright pink flowers, just like many varieties of nasturtium eventually revert to standard bright orange and yellow. It is hard to say now, while naturalized four o’clocks have yet to do so.

Six on Saturday: Not My Garden

 

My garden really is not much to talk about. Really. It is just a bunch of redwoods with a bit of other native vegetation dominating the few items that I added into the mix. There are fourteen stock fig trees, but they are very small and mostly obscured by the underbrush. The elderberries, currants and huckleberries are the same as what grows wild, so they do not look like much either. Even the cane berries look very similar to the native blackberries. There is a quince tree, some rhubarb, and some small prickly pear, but they are barely visible amongst the other vegetation. Well, that is enough talk about why my garden is not much to talk about.

These pictures are from one of the gardens that one of my colleagues maintains.

1. Hibiscus is probably the flashiest bloom in this garden now. I have no idea what cultivar this hibiscus is; and I am not even certain about the species. It sure is impressive though. This flower is more than six inches wide!P80901

2. Red honeysuckle is something that I really want to grow, but can not justify it. I mean, it does not exactly ‘do’ anything more than look good. It is not fragrant like Japanese honeysuckle is. This one took a while to bloom.P80901+

3. Zonal geranium happens to be one of my favorite perennials, even if others consider it to be too cheap and common. I do not know if this one is pink, peach, salmon . . . or one of those odd colors that only girls can see.P80901++

4. Mandevilla is my best guess. Again, I do not know the species. Did I mention that this is not my garden? I do happen to like this one though, because it is so perfectly white. Otherwise, I am none too keen on mandevilla.P80901+++

5. Morning glory is quite happy here. This one is annual of course. There was a perennial white morning glory known as a moonflower nearby, but it succumbed to frost last winter. Hope for its recovery ran out months ago.P80901++++

6. 4:00 (four o’clock) is a prolific naturalized exotic species. I would not say that it is invasive, but merely prolific. I do not know if this one is 4:00 a.m. or 4:00 p.m., but I do know it will not be the last. More on that later.P80901+++++

Fernleaf Yarrow

70830‘Moonshine’ is probably the epitome of fernleaf yarrow, Achillea filipendulina, even though it is technically a hybrid. From the middle to the end of summer, its three inch wide corymbs (flat-topped trusses) of tiny bright yellow flowers stand as high as three feet above ferny and gray basal foliage. Bloom is best in full sun and warm exposure. Established plants do not need too much water.

Most varieties of fernleaf yarrow also bloom with bright yellow or gold flowers. Some might bloom with pale yellow, rosy pink, pale pink, reddish, white or pink and white flowers. All are good cut flowers, and can be dried. Some varieties are more compact. The most compact varieties work nicely in planters of mixed perennials. Butterflies and hummingbirds find them wherever they are.

Pruning out deteriorating blooms may promote sporadic subsequent bloom until autumn. However, some plants may bloom all at once, and then not bloom again until the following summer. Large blooms on the most vigorous plants may need to be staked. New plants can be propagated by division from mature plants. ‘Moonshine’ and many other cultivars are sterile. Others might self sow.

Flowers Might Be Getting Scarce

70830thumbIt makes sense for flowers to bloom in spring. Winter is too cool, windy and damp for both flowers and the insects that pollinate many of them. By summer, successfully pollinated flowers have faded, are busy making seed to disperse in autumn. Some plants produce fruit to get birds and other animals to disperse their seed. There are certain advantages to blooming early in the spring.

Native plants that are endemic to chaparral climates are quicker with bloom, so that they finish before the air gets too arid. Desert plants might bloom for less than a week. Some tropical plants might bloom whenever they want to because they do not understand the concept of seasons, but they are not the prominent plants in our gardens. Therefore, flowers get scarce this time of year.

Besides the few perennials and annuals that bloom as long as the weather stays warm, there are not many plants that bloom reliably so late in summer. Belladonna lily, which is also known as naked lady, might be one of the flashiest, as its bright pink flowers bloom on top of bare stalks before the low basal foliage develops. It was actually dormant through the warmest part of summer.

Billowy and bold pampas grass flowers bloom this time of year, but are uncommon. The boldest type of pampas grass is too big and difficult to manage for home gardens. The smaller type has dingy tan flowers, and is so invasive and weedy that it is unavailable in nurseries. Those of us who have it in our gardens did not plant it. Other grasses with nice late flowers are not very colorful.

Russian sage has become one of the more popular late blooming perennials. More traditional Japanese anemone, goldenrod, lion’s tail and showy stonecrop all seem to have lost popularity over the years. Mexican blue sage should bloom best late in summer, but often finishes sooner than expected. Yarrow often blooms later than expected, until summer ends. Marigold, blanket flower and some sunflowers bloom until frost. Chrysanthemums, whether grown as annuals or perennials, are just beginning late in summer.

Horridculture – CH CH CH CHIA!

P80829Skyscrapers are already very efficient. They fit more usable floorspace into their ‘footprint’ than any other type of building does. They conserve energy that gets used for heating and cooling by exposing less of that floorspace to the outside weather. For all that usable floorspace, they need only a single roof.
Think about it. A relatively short ten story building contains as much floorspace as ten single story buildings that occupy the same area individually, but collectively occupy ten times as much area! Nine of those stories loose heat during cold weather, and collect heat during hot weather, only around the exterior walls. Only the top floor loses and collects heat through the roof, and only if there is not an upper utility ‘attic’ floor that insulates it. Ten single story buildings of the same area are all exposed on top, as well as all the way around. Of course, ten single story buildings of the same area need ten roofs comparable to the single roof of the ten story skyscraper.
Skyscrapers certainly need more infrastructure to support all of their floors, and they lose a bit of their floorspace to that infrastructure, as well as to the elevators needed for access to the upper floors. It also takes significant energy to pump water up to upper floors. Regardless, skyscrapers are still the most efficient of buildings. They have nothing to prove to the treehuggers who dislike them so.
‘Green roofs’ on top of skyscrapers are a fun concept. They utilize space that is otherwise useless, and they really do help to insulate the top and most exposed floor of big buildings. However, they are no more ‘green’ than landscapes that are at ground level. In fact, they necessitate the incorporation of extra infrastructure into their respective buildings in order to sustain their synthetic environments, and to support the extra weight of the soil, water and flora. Pumping water to irrigate green roofs takes more energy than irrigating landscapes at ground level. Generally though, they are probably worth the effort, as long as they are not too elaborate,
Chia Pet Skyscrapers are what happens when they get too elaborate. The vertical landscapes incorporated into the facades of these buildings consume more resources and energy than they conserve. Although less energy is needed for cooling the buildings during warm weather, more energy is used to pump water for irrigation. Not only must the buildings be constructed to sustain these landscapes, but they require much more specialized maintenance than conventional skyscrapers need. Because the flora in these vertical landscapes can not disperse roots into real soil, the growing medium must be fertilized very regularly with more synthetic fertilizer than conventional landscapes in the ground need, and all this fertilizer eventually leaches into the drainage systems of the landscape. Insects might enjoy these vertical landscapes, but the necessary regular maintenance would prevent much other fauna from getting established like they could in conventional landscapes at ground level.
Although the skyscraper within this spectacular Chia Pet Skyscraper benefits the environment, the vertical landscape that adorns the exterior only benefits those who live and work in and around it.

Cosmos

80905Their pastel hues and blends of pink, lavender, near red and white are so perfect for the middle of spring when cosmos, Cosmos bipinnatus, begin to bloom. They are just as perfect as bloom continues right through summer and almost to autumn, when the tall and airy plants finally begin to wear themselves out. If they continue through autumn, they eventually succumb to frost in winter.

Individual flowers are as delicate as they look, but are prolific. New flowers replace older flowers a quickly as they fade. Deadheading promotes even better bloom. A few of the last flowers to bloom can be left as the season ends to sow seed for next year. However, fancy cultivars are not true to type, so subsequent generations will be more like the basic specie, with simpler flowers.

Cosmos likes full sun exposure, rich soil and regular watering. Mature plants are about two or three, or even four feet tall, although the most popular varieties stay shorter and more compact. The species name of ‘bipinnatus‘ refers to the pinnate leaves that are divided into very narrow lobes that are also divided into even narrower lobes. The collective foliage is very delicate, lacy and airy.

Flowers For Late Summer Bloom

80905thumbNo mater how much work we put into our roses to sustain bloom all through the season, and not matter how successful we are with that endeavor, the first spring bloom is always the best. Some roses continue to bloom in floriferous phases afterward, while others bloom sporadically but continually; but there is nothing like the first bloom phase. The last blooms are just waiting for autumn.

Of course, concentrating resources into early bloom is very sensible. That is why so many plants bloom only once in spring. It gives them time to get pollinated, develop seed and fruit structures, and finally disperse their seed or fruit structures, all before winter. Plants that bloom in summer or autumn are either from regions where winters are not too harsh, or where summers are harsher.

Because summer weather in most regions tends to be warmer and drier than spring weather, flowers that prefer to bloom in summer tend to be more prolific but smaller and less colorful. By this time of year, they are more reliant on wind for pollination rather than insects anyway. Therefore, they do not need to be big and colorful to attract pollinators, although some are fragrant just in case.

Sunflower, blanket flower, cone flower, zinnia, cosmos, delphinium, dahlia and of course rose, are some of the favorite flowers in the garden as well as for cutting in late summer and into autumn. Cut dahlia flowers should get their water changed daily so that they do not rot and smell bad so soon. Canna blooms about now, but does not last so well as cut flowers. Lily-of-the-Nile is finished.

Believe it or not, lemon bottlebrush is a delightful cut flower for those who are not allergic to it or repelled by the aromatic foliage. So are some of the showier eucalyptus, such as the red flowering gum, Eucalyptus ficifolia. Mexican blue sage that was cut back to the ground over winter blooms a bit in spring, takes a bit of time off through summer, and then starts to bloom as summer ends, ultimately blooming spectacularly early in autumn. A few other sages bloom as late, but few are good for cutting.

Scarlet Pimpernel

P80826It is pretty but pervasive. Actually, I do not really find scarlet pimpernel to be all that appealing, but this is how someone who reads my gardening column in the Santa Ynes Valley News describes it. Embarrassingly, she requested that I discuss scarlet pimpernel while it was more of a problem back on June 7, but I only recently read the message. By now, it is already dying back for autumn, and is completely deteriorated in dry and hot exposed areas. It will be back next spring, and will bloom with tiny peachy orange flowers so that it can throw tiny but ridiculously abundant seed by summer before anyone notices. Flowers can be other colors in other regions. The sprawling stems can spread more than a foot wide, and can get up to about ten inches high if sprawling over other weeds. The tiny and soft leaves are arranged in opposing pairs. Scarlet pimpernel may not seem like much of a threat now that it is deteriorating, but new seedlings will be profuse early next spring, and can compete with seedlings of more desirable plants.
Control of scarlet pimpernel is not easy. If application of herbicide is an option, it does not stick to the foliage of scarlet pimpernel very well, even with a wetting agent. Hoeing eliminated larger plants, but does not kill the seed that the larger plants have already tossed. Scarlet pimpernel starts throwing seed so early that it must be pulled as soon as it appears in very early spring. Like I said, it is not easy. The small plants are not even easy to see. The process must be repeated at least weekly for a while, just because some seedlings will emerge after the first batch is gone.
Fortunately, scarlet pimpernel is not very vigorous. If it comes up through mulch, only a few plants will survive, and they will be easy to pull. They do not compete with other more vigorous plants well either. Many simple ground covers will simply shade it out, although it can mingle with and ruin some of the finely textured ground covers like baby tears and thyme.
I am sorry that I do not have any more information about scarlet pimpernel than is commonly known. I am speaking primarily from experience, and my experience has not been as bad as with other more aggressive weeds. Scarlet pimpernel always seems to be around, but is not so much of a problem that I am too worried about annihilating it completely.P80826+

Big Trees

0

They are the biggest. Giant redwoods are revered for their age and size. It was not always like that.
Many of the biggest giant redwoods were killed merely for bragging rights. Whoever discovered the biggest got to arrange to get it cut down, and then pose on the stump for photographs. Some trees were cut down just so the rings could be counted. Many felled trees were just left to rot where they fell. It was not practical to transport the lumber out of the remote regions of the Sierra Nevada where the trees lived. That was at a time when ‘sportsmen’ shot from trains into herds of wild buffalo, only to pose with the biggest dead carcass they could find in the aftermath, and then leave all of the deceased to rot on the prairie.
So, at about the same time in history that the related coastal redwood was being harvested so indiscriminately for lumber, the biggest of the giant redwoods were killed primarily for sport. Even in regions from which lumber could have been transported from, no one could figure out how to get such massive giant redwoods onto the ground without fracturing the lumber within. Because their wood is so brittle, smaller giant redwoods that were harvestable were simply cut and split into shakes, grape stakes, and fence posts and rails. Young and healthy specimens of the biggest trees in the World were used for the smallest and most unglamorous forms of lumber.
The biggest of the giant redwoods are of course protected now, mostly within national parks. They are quite accessible to those who want to visit and admire them. I got this picture with one of my esteemed colleagues in front of the General Sherman tree in wintertime back in the early 2000s.
