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.

Six on Saturday: Redwoods Again

 

Redwoods are such interesting trees. There is always something to write about them. I happen to live and work within the native range of the coastal redwood. I often work with very big redwoods, both in the wild, and in landscaped areas that were formerly wild. There are no other trees that are comparable. The giant redwoods in the Sierra Nevada are bigger, but they are also very different.

1. In most home gardens and landscapes, trees that get cut down get recycled into greenwaste and firewood. Not many are big enough to get recycled into lumber. Even fewer are big enough to get milled into big timbers. This milled redwood lumber is drying before getting milled again into timbers and smaller sizes of lumber that will get used to repair and remodel some of the historical old buildings. A bit of pine lumber is also obtained from the big ponderosa pines nearby.P80825

2. Limbs, foliage, bark and parts of the redwood trees that can not be milled into lumber get chipped. Chips get used as mulch in landscaped areas. After taking this picture, I realized that it is not really a pile of chipped redwood, but is instead chipped wood waste. Chipped redwood is typically green with foliage. Oh well, you get the idea.P80825+

3. The Ewok Village of ‘Star Wars IV – Return of the Jedi’ was in a redwood forest near Fortuna. This is not really an Ewok Village.P80825++

4. It is a Redwood Canopy Tour. People (not Ewoks) can be seen on a platform in the yellow rectangle just above and to the right of the center of the picture. Someone on a zip line can be seen in the white rectangle just below and barely to the left of the center. It looks crazy to me, but many of my colleagues do crazier things at work.P80825+++

5. Most of us have seen pictures of massive redwood trunks. Most of us have seen pictures of redwood forests. Not so many of us have seen what the foliage looks like.P80825++++

6. This perennial pea has nothing to do with redwoods, but needed to be included as a token flower for this week. Besides it is cool. It is softer pink than the bright purplish pink that is so typical, and is blooming very late.P80825+++++

California Bay

70823Just because California bay, Umbellularia californica, can be used like Grecian or sweet bay for culinary purposes does not necessarily mean that it should be. California bay has a stronger and much more pungent flavor and aroma. Some might suggest substituting less than half California bay for Grecian bay. However, even if the intensity is adjusted accordingly, the flavor might be off.

As the name suggests, California bay is native to California. However, because it is from rainier climates, it prefers a slight bit more water than it would get naturally in the drier parts of the local chaparral climate. It provides nice cooling shade in large landscapes, but is a bit too dark and messy for refined home gardens. The aromatic leaf litter can annoy delicate annuals and seedlings.

Well exposed trees can eventually get more than thirty feet tall and almost as broad. Forest trees that compete with other trees can get a hundred feet tall! Small trees can be shorn as hedges. If not watered too generously, the roots tend to be rather complaisant. However, old trees can eventually develop massively distended burl growths known as lignotubers at the bases of their trunks.

Herbs Are For All Seasons

70823thumbThere are only four seasons in which to grow herbs, but herbs are used for all sorts of seasonings. Most herbs are aromatic evergreen foliage. Some might be flowers, flower buds, stems, bark, seeds, roots or really any plant part. Those with the strongest flavors might be classified as spices. Herbs are used for culinary purposes. Many might be used medicinally. Some just smell pretty.

Most herbs are best fresh, like mint, chive, cilantro and parsley. Bay leaf and lavender are herbs that are more commonly used dried rather than fresh. Sage, rosemary and oregano can be used either dried or fresh, depending on the desired effect. Yet, for many of us, dried herbs are used merely because of convenience. They are available when their fresh versions are out of season.

Many gardening texts suggest that herbs that need to be dried should be collected and dried about now. That is true in the sense that most happen to be ready about now. Some might have been better earlier in the year. A few might need to mature a bit more. There are probably many that get collected and dried when it is convenient for us, or when overgrown plants need to be pruned.

Vegetative rosemary stems should be collected before they bloom again. Obviously, that might not be right now. It blooms in random phases. The trick is to catch it between phases. Lavender flowers get collected as they finish bloom. Oregano is an odd one, since the vertical stems with flower buds on top get cut for drying while the sprawling growth on the ground is good for fresh use.

Because rosemary is available throughout the year, it is not often dried. Even while in full bloom, there is plenty of foliage to go around. When it gets dried, it is probably because the dried flavor is preferred for a specific recipe. Other herbs are likely to be dried because they are not available during part of the year. Many herbs are annuals or perennials that die back through the winter. Drying the last bits of cilantro may not seem like a good idea now, but might be useful in winter.

Horridculture – Agave

06When they became a fad in the 2000s, it was one of the very few fads that was actually sensible for California. Agaves certainly are not for every landscape, and certainly do not suit everyone’s taste, but they are ideal for the climate here. In some regards, they are more practical than the more popular of the native specie that tend to be scrubby looking and short lived. Agaves really should have become trendy a long time ago.
The problem with the fad, like so many other fads, is that it caused the object of desire to be overly popular for a while. Many agaves consequently got planted into situations where they did not belong. Landscape designers often forced them into the gardens of clients who did not know what they were, or did not even like their bold style. To show them off most prominently, designers often put the agaves next to walkways, driveways and doorways, rather in the background.
Those who know agaves know that they belong in the background because of their nasty foliar teeth! Technically, they are neither thorns not spines, but they are so wicked that they are known by both terms. These teeth are remarkably sharp and stout. Next to walkways and doorways, they can inflict significant injury to anyone unfortunate enough to bump into them. Next to a driveway, they can puncture tires! The foliar teeth of agaves are so dangerous that they do not belong anywhere in the gardens of homes where children or dogs live.
What is worse about those that are too close to walkways and such is that they grow! Landscape designers are notorious for installing small agaves that grow large in tight spots, merely because they were so cute and innocent when they were small.P80822K
