Horridculture – The Wrong Plant In The Wrong Place

P80627This is the opposite of the ‘right plant in the right place’. It is something that horticultural professionals should neither promote nor tolerate when feral plants appear in landscapes that they are getting payed to maintain. This example looks like it is more relevant to the topic of ‘Fat Hedges’ from https://tonytomeo.wordpress.com/2018/06/06/horridculture-fat-hedges/ , but there is more to this feral pyracantha than that. Yes, it is shorn too frequently to bloom or produce colorful berries. Yes, it looks like an upside-down and halfway buried Christmas tree. Yes, it contributes nothing to the landscape. What is worst of all is that it does not even belong there. It was certainly not planted there on the edge of the curb. There are others nearby, but they happened to appear in spots where they could have actually been assets to the landscape if they had not also been shorn into this weird upside-down and halfway buried Christmas tree shape.

Pulling or at least cutting weeds is generally one of the responsibilities of maintenance ‘gardeners’. It might be acceptable or even preferred to leave a few feral plants if they happen to appear where they might be useful. Those that appear where they would be a problem must be removed. It really would not have been much work to pull this particular pyracantha if it had been done when it first appeared. Even if it had not been pulled right away, and gotten cut down by a weed whacker long enough to develop strongly attached roots, it could have been dug out while young with only a bit of effort.

Okay, so that is in the past now, just like all the other days, weeks, months and years that this feral pyracantha was not removed. Okay, so if for some reason known only the maintenance ‘gardener’ who likely charges significant fees for the maintenance of this landscape, this specimen is to be salvaged, should it not have been pruned back away from the curb? Of course! Although it is right on the curb, much of the growth could have been directed back away from the curb and over the bare embankment. That area is not used for anything anyway. The emptiness of the embankment is certainly no asset to the landscape. Empty pavement is an asset here.

A chain is only as strong as the weakest link. A driveway is only as wide as the narrowest part. All this asphalt pavement and concrete curb is expensive. It was probably worth it to get a nice wide driveway. However, the usable area is not as wide now as it was originally. The feral pyracantha that looks like an upside-down and halfway buried Christmas tree extends nearly four feet into it. That means that the usable space of the expensive driveway is nearly four feet narrower in that spot than it should be. Just think of all the expense that could have been saved if the driveway had been constructed four feet narrower than it had been!

Coneflower

80704The native American coneflower, Echinacea purpurea, of the Midwestern prairies has been popular within its native range longer than anyone can remember, and has become more popular in the West as extracts of echinacea became a fad in herbal medicine several years ago. Modern garden varieties and cultivars have been bred and hybridized for larger and more colorful flowers.

Coneflower has developed from a sturdy but relatively simple prairie wildflower into a flashy and potentially garish perennial, with white, pink, red, orange, yellow, purplish pink or pale green daisy (composite) flowers as wide as three or even four inches. The fat and bristly rust-colored centers become more prominent as the outer petals (ray florets) fold downward to form a domed cone.

The sturdy upright stems can get taller than three feet and wider than two feet, although some garden varieties are more compact. The somewhat raspy basal foliage is full and fluffy, but becomes progressively sparser higher up the stems. Some rare cultivars bloom with double flowers. New growth replaces the old annually, and with plenty of sunlight, blooms through the warmth of summer.

Medicinal Herbs Versus Culinary Herbs

80704thumbThey are NOT the same thing! Many herbs can be useful for both culinary and medicinal applications, but the distinction between the two is very important. Culinary herbs are used to flavor foods. Medicinal herbs are used like pharmaceutical drugs; but they lack the main safety feature of standardization. That means that they are potentially toxic and seriously dangerous if used improperly!

Even standardized pharmaceutical grade herbal products that are very precisely portioned into specific doses that contain very specific rates of active ingredients have the potential to be toxic if misused, and are of course toxic to anyone who is allergic to what is being used. They must be regarded with the same sort of caution that is warranted by any other pharmaceutical medication.

Digitalis is a perfect example of a very toxic plant that is used medicinally. All parts of the plant are very poisonous! Digitalis is so toxic that it is no longer used directly as an nonstandardized and nonpharmaceutical medicinal herb. However, in a standardized pharmaceutical form, it is still sometimes prescribed for cardiac disorders. Many of us grow it just for elegantly tall flower spikes.

In our own home gardens, the strictly culinary herbs are relatively safe. Even those that can also be used medicinally are not likely used for culinary applications in quantities sufficient to be toxic. Some herbs that are used for herbal tea have more potential for toxicity, particularly if consumed regularly or excessively. Even seemingly innocuous chamomile tea, in excess, can cause nausea.

Herbs that are grown and used for medicinal applications warrant the most caution. The active ingredients as well as other chemicals in such herbs can not be accurately quantified, and are quite often variable. Doses that are measured as small volumes of plant parts might contain minimal traces of active ingredients, but could just as easily contain toxic rates. Herbalists recommend consulting with a physician prior to using any of the more potent of medicinal herbs, even if the herbs come from the garden.

Fiercely Local

P80624There are two terms that I avoid using within the context of my writing:

1. SILICON VALLEY – The name of the main newspaper group that I had been writing for since 1998, almost twenty years ago, is the Silicon Valley Community Newspapers. As much as I enjoyed writing for the small local newspapers of the group, I hate the name. I find the term ‘Silicon Valley’ to be offensive. It exemplifies that which destroyed the idyllic culture and lifestyle of the Santa Clara Valley, which is also known as the Valley of Heart’s Delight. I have never written the term until now.

2. BLOG – It is the contraction of ‘web log’. The ‘log’ in ‘blog’ is not what bother me. It implies a chronological journal, perhaps documenting experiences that are relevant to a designated topic. It is the ‘b’, or more specifically, the ‘web’ in ‘blog’ that is the problem. It implies that information posted on a ‘blog’ gets shared on the World Wide Web. The reason that I avoided sharing my gardening article on the World Wide Web for so long is that they are written very specifically for the Santa Clara Valley. Although some of them are rather universal to gardening, and some are relevant to regions with similar climates and soils, some are not relevant and perhaps inaccurate for other regions.

My gardening column started with the Silicon Valley Community Newspapers, which at that time was ‘fiercely local’. I always thought that was an odd term, but it makes sense. It means that each of the local newspapers features news that is relevant to their specified local communities. Los Gatos Weekly Times was for the news of Los Gatos. Saratoga News was for the news of Saratoga, and so on. When I started writing my gardening column, I wrote about gardening within our local climate and local soils. I could write about local gardening events and even the weather it it happened to be particularly relevant to gardening at the time.

As the gardening column was added to other newspapers in other regions, I was no longer able to write about local events or weather. I was very fortunate early on that all of the newspapers that used the column happened to be within the same climate zones. However, when it was added to the Canyon News of Beverly Hills (in the region of Los Angeles), and a bit later to the related San Francisco News, it became necessary to modify some of the articles to accommodate for differences of climate. Articles that were universally applicable needed no modification. However, those that were too specific to our local climate needed to be edited for the other two climates. For example, when writing about bare root fruit trees, I deleted discussion of apple and pear trees from the copy of the article that was sent to the Canyon News, and replaced it with discussion of bare root plants that are popular and appropriate in that particular region.

Over the years, I realized that my articles became too available online. Not only were they posted within the context of the online versions of the newspapers that had access to it, but they could be inadvertently opened from other related online newspaper . . . or just about anywhere. Someone in Oklahoma, Pennsylvania, Australia or anywhere in the World could click onto one of my articles just as easily as a local article, and could do so without knowing that it was written for a completely different climate or hemisphere!

I explain in my ‘About’ section that the articles are written for the Santa Clara Valley, but I doubt that means much to those who find the articled without seeing that explanation. I will continue to write my article for the newspapers that still use them, and will continue to post those articles, as well as ‘elaborations’ articles on my ‘blog’. Like so many other gardening articles that are out there nowadays, they will be inaccurate for some regions. Those reading them will need to use their own discretion.

What is sad about all this is that I started writing my garden column precisely because I was so frustrated with what was being published in the San Jose Mercury News at the time. It was typically written quite well, and by professional writers, but was very often very inaccurate because those writing it were either writing for other regions, or simply knew nothing about horticulture. I was so pleased with the opportunity to write accurate information about gardening for our region. Yet, after all these years, I feel like I am now doing exactly what I found to be so frustrating twenty years ago.

Upgrade

P80624.jpgThis autumn, it would have been twenty years that I have been writing my weekly gardening column for the Silicon Valley Community Newspapers, affectionately known as SVCN. It would have been excellent if it had lasted that long, but it was discontinued a few months ago. There was no warning, although we all know the direction that such media is going nowadays, and that such changes are abrupt. Nothing is like it was nearly twenty years ago.

My weekly gardening columns will continue for the other newspapers that still use it, even if they do not use it for their print versions. Again, due to the way such media operates nowadays, I have no idea of which newspapers who have access to it actually use it, or if they use it for their print versions or merely their online versions.

I could elaborate on the history of my garden column and its inclusion into the various other newspapers that continue to use it, but that can just as easily be another topic for another time. Perhaps I will merely put a bit of that information in my ‘About’ section if I ever get around to updating it. I have another topic to discuss now.

I would like to upgrade this blog. I would like to make it as fancy and user-friendly as some of the other blogs that are out there. I know that the last thing I need right now is more work, but I also want to maintain this as an venue for my weekly gardening column, particularly if other newspapers are likely to discontinue using it in the future.

Upgrading will include selling add space, or at least making add space available to advertisers who can use it. Newspapers pay very minimally for my weekly gardening column, and the newspaper group that payed the most for it no longer uses it. Advertisements might help to justify the work that goes into writing a new gardening article weekly. Hopefully, no one will be to bothered by these changes. I have enjoyed writing my weekly gardening column for almost twenty years, and would like to be able to continue doing so for a while longer.

Summer Deciduous

P80623K+++That is a term that we do not hear much. There are not many plants that it applies to. Cyclamen is one of the more familiar plants that is summer deciduous. It is from a climate with reasonably mild winters and unpleasantly dry and warm summers. Just like most deciduous plants are dormant through winter to avoid the unpleasantries of the weather, cyclamen defoliates as the weather gets warm in early summer to avoid the expected heat and aridity. It somehow knows how to stay dormant until the weather starts to get cooler in autumn, and is ready to regenerate new foliage and bloom as the rain starts. The active growing season is through autumn, winter and into spring. It is all a matter of taking advantage of the weather while it can, and avoiding the discomforts of severe weather when necessary.

Rhody, like most dogs, has been shedding his fluffier inner winter coat through spring. He still seems to be too fluffy for the weather, but he must know what he is doing. The remaining wiry outer coat provides a bit of shade, and helps to dissipate a bit of warmth when necessary.

Unlike Rhody, I do not have a fluffier undercoat to shed. All that I could do is shed some of the sparse and wiry outer coat. It might have provided shade, but also interfered with cooling air circulation. It does not seem to be designed to dissipate heat like Rhody’s is. Regardless, it was shed just before the Summer Solstice, and will not regenerate until autumn. A barber sheared back the upper evergreen growth first. I then pollarded most of the lower growth, leaving only a pair of formally shorn hedges flanking the upper margin. They too may be removed soon.

Six on Saturday: Nursery Rhyme

 

I wish we had one. There is no rhyme and only a few disjointed reasons for what happens at the small storage nursery at the maintenance shops. This is nothing like acres of production nursery full of rhododendrons, azaleas, camellias and such. Nor is it like the retain nurseries that sell the rhododendrons, azaleas, camellias and such. This is merely a small yard where we store a few plants that get removed from landscapes, and plants that were recently procured from a nursery but have not yet been planted.

It is like the nursery version of the wood shop, with its collection of new lumber and old recycled lumber that gets used on the historic buildings. The plumbing shop contains all sorts of new plumbing and fixtures, as well as many old fixtures that might someday be useful. The landscape shop, which is separate from the nursery, is #7 of about twelve specialized shops used by the maintenance staff. The nursery might seem to be the most dysfunctional of the several shops, but only because plants are dynamic and need maintenance . . . and because, without necessary maintenance, a few have deteriorated, died or conversely thrived and made themselves at home.

Newly procured plants like #5 and #6 are easy to work with. They come in with a plan, and generally leave within a week or two as they get installed out somewhere in the various landscapes. Recycled plants like #1 and #2 were removed from the landscapes either because they were in the way of something, or because they proliferated too much, but could someday go back into other landscaped areas. Then there are a few plants like #3 and #4 that stay long enough to disperse roots through the bottoms of their cans and into the ground, essentially planting themselves on the spot because they got tired of waiting for a new home.

1. Peruvian lily was so prolific at the Post Office that many needed to be pulled. They were canned to be installed elsewhere, but no one wants to put them into a situation where they might proliferate like they did at the Post Office. Besides this pink, there is also peachy pink and yellow. All are the tall types that were originally grown fro cut flowers, rather than the lower mounding home garden varieties. Consequently, they need to be staked or caged like tomatoes so that they do not lay on the ground.P80623
2. Chrysanthemum was grown as annuals in a few various locations, but when they were removed to relinquish their space for more seasonable annuals, a few were canned. It is not always easy to discard certain perennials just because their time is up. The problem is that, although they look so good in the nursery, and bloom in spring instead of autumn, they do not get cycled back into the landscape. When new color is needed, it is often purchased and planted before the old stock is considered.P80623+
3. Potato vine has been growing like a weed on the cyclone fence and shade structure for so long that no one knows where it came from. I do not even know where the vines originate from. I would guess that somewhere under the overgrowth, the main canes emerge from the remains of a #1 can that the roots split apart years ago. This vine lives here now. Even if we had a spot for it, relocation is not practical. If it gets too overgrown, it might get cut back.P80623++
4. Campanula was probably in a 4” pot that got set into the #15 can of a ‘Black Lace’ elderberry and forgotten about. It might have been recycled, or it might have been something new that never got installed. Before the elderberry was relocated, the campanula had spread into the cans of other trees, so like the potato vine, it lives here now.P80623+++
5. Cone flower is easy. I just arrived from a nursery, and will be installed into a landscape in just a few days.P80623++++
6. Yarrow came with the cone flower, and will be planted nearby in the same landscape at about the same time.P80623+++++

Mandevilla

70621Pink, red or white are the only choices. There happens to be a darker shade of red. Yellow throats are more conspicuous in white flowers. Otherwise, there is not much variation of color amongst the various mandevillas. The flowers are very similar in both color and form to those of related oleander, but are larger. Some are as wide as three inches. Small flowers can have pointed petals.

Mandevilla vines are surprisingly vigorous and sneaky. The lower portion of a mature plant may seem to be rather tame while it extends aggressively twining vines into trees above. Vines on small trellises can get congested on top. Pruning upper growth helps to even out growth and bloom. Exposed vines are likely to get killed back by frost in winter, but should regenerate efficiently.

The evergreen foliage is quite glossy. Some varieties have interestingly rippled leaves. Partial shade is best for rich green foliar color. Full sun can scorch leaves. Dipladenias are very similar to mandevillas, but are shrubbier and more compact, with smaller flowers and leaves. They are probably a better option for large pots. Sap of both mandevillas and dipladenias is caustic and toxic.

Catalog Shopping Has Certain Limits

70621thumbThe temptation is unbearable. The catalog of Adelman Peony Gardens, either in print or at www.peonyparadise.com, shows how spectacular peony blossoms can be. There are one hundred and seventy-eight exquisite pictures of the cultivars available for mail order on online purchase. The only problem, and it is a big one, is that peonies are recommended for USDA Zones 2 through 8.

So maybe some of us in Zone 9 might conveniently neglect to read that part of the catalog. Maybe some of us believe that since peonies can not read that part of the catalog, they might not mind getting cheated out of the winter chill they need for good dormancy. Somehow, many of us are able to grow peonies where they have no business growing. Perhaps we should keep that a secret.

So many more plants are available online and by mail order than can be found in nurseries. Most of them are appropriate to local climates. Some are not. Catalogs from the best nurseries are careful to make that distinction obvious by describing what zones their plants are recommended for. That can be a lot of information for nurseries that have many different types of plants available.

Plants that have potential to transmit disease or become invasive might be banned from certain states. Nurseries can send plants to inappropriate climate zones for clients who really want them, but can not send plants to states where they are banned. Black elderberry plants can not be imported into California. Only black elderberry plants that were grown in California can be sold here.

Unfortunately, many plants are sold online without any regulation whatsoever. Anyone can sell any extra seeds, seedlings or cuttings online, whether or not they actually know what the seeds or plants are. Some plants are not really what they were described as when sold. Many others get sent to climates where they will not be happy, and might not even survive. Worst of all, there is serious potential for plants to be vectors of disease and insect pathogens, or to become invasive in formerly uninfested regions.

Horridculture – Stub

P80620.JPGHow can a professional ‘gardener’ leave such a stub on the little California black oak in Felton Covered Bridge Park. It is not as if it is high in the canopy of a large tree, and out of reach to an arborist. This one is right at eye level, exactly where someone getting out of a car parked in the adjacent parking space would run into it. The entire tree needs some major corrective pruning, which would include the removal of significant limbs and portions of the canopy, but that is only because of years of neglect, and is another story. Right now, we are focusing on the eye-level stub.

It is not easy to see in these pictures because the lower branches are so congested. The stub extends from the lower left to the upper right in the first picture. It is right in the center of the second picture, protruding upward and to the left of the trunk, and then kinking back to the right. The last picture shows how easy it would be to reach from the ground. This particular tree is located right across from the Memorial Tree. https://tonytomeo.wordpress.com/2018/04/15/memorial-tree-update-to-the-updated-update-etc-the-sequel-to-all-those-other-sequels/

We are always taught to not leave stubs. They interfere with compartmentalization of the pruning wound, or in this case, grow back into a disfigured wad of useless growth that will just need to be removed later. This poor tree already has plenty structural problems. Even if it were not unhealthy for the tree, it is just plain unsightly. Seriously, this looks ridiculous.

‘Gardeners’ do it all the time, as if they all take the same class on ‘how to leave stubs’. What was the advantage to cutting the limb right there instead of two feet closer to the trunk to eliminate the entire stub?P80620+P80620++
