Summer Deciduous

Should I be embarrassed by this article from three years ago? Yes. Am I? No.

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.

Fiercely Local

You know, three years after this recycled article posted, I am a bit more tolerant of the term ‘blog’. I like to think that my writing style is more relaxed now, although I have not written much more than my gardening column in quite a while.

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…

Six on Saturday: Some Like It Hot!

The climate here is mild. Winter chill is insufficient for some peonies and apples. Summer warmth is generally tolerable, particularly since humidity is generally low. Nonetheless, the weather occasionally gets quite warm. Fortunately, when this happens, it does not last for too long. It started to get unpleasantly warm on Wednesday, then remarkably hot on Thursday, but was then comfortably warm for Friday. I know that it is not much to complain about; but even brief warmth can damage the landscapes here.

1. Astilbe is something that I have wanted to grow since about 1987. I just never found a good excuse to do so. This is not mine, but was added to two of the landscapes at work on Wednesday.

2. On Thursday, a few of the fresh new astilbe looked like this. The weather got too warm, too fast. Gads! This is my first experience with astilbe. Fortunately, they are green and viable within.

3. Shade is certainly not a rare commodity here. Redwoods are the tallest trees in the World, and many live in and around the landscapes. It would have been even warmer here without them.

4. When I say that redwoods are tall, I mean that they are ‘tall’. This one is known as the woodpecker tree because woodpeckers store acorns in the perforated bark. Its shadow reaches Utah.

5. Anyway, this is how hot it almost got. The actual temperature was likely slightly less than this, but enhanced by the metallic roof above. What difference does it make? It was hot regardless!

6. Rhody knew what he wanted to do while it was so unbearably hot. He went out and laid in a sunny spot on the hot asphalt. He rolled around a bit too. He went for a swim in the creek later.

Daylily

These flashy blooms are remarkably easy.

As the name implies, each individual flower of daylily, Hemerocallis, lasts only about a day. They open just after dawn, and wither by dusk. However, bloom last from a week to a month because there are several flowers on several stalks. These flowers take turns blooming, so that a flower that blooms today will likely be replaced by a new flower tomorrow, until bloom finishes. Some daylilies bloom early in spring. Others wait until summer. A few bloom again, as late as early autumn.

Flowers can be almost any color except for blue or white, and typically have a a different color in the throat. The most popular varieties are bright yellow, pastel yellow, orange, pink or rusty red. Purple flowers are not quite as flashy as the color implies. Each flower has six petals, (which are actually three petals and three sepals). Bare stems hold the flowers about two feet high, well above the clumping grassy foliage. Some stay only a foot tall. A few get considerably taller. Plants should be groomed of finished flower stems, and may sometimes want to be groomed of deteriorating foliage. Daylilies known as ‘deciduous’ daylilies shed all foliage by autumn.

Perennials provide foliage and bloom

Bloom can repeat in season perennially.

Does anyone really know what a ‘perennial’ plant is? It is obvious that it is not an ‘annual’ plant that lives only a single year. A ‘biennial’ plant produces vegetative (non-blooming) growth in the first year, and then blooms, develops seed, and dies in the second year. A plant only needs to live more than two years to be a perennial plant, or simply a ‘perennial’. Well, that does not narrow the definition down much. Bristlecone pine can live for thousands of years, but is not often thought of as a perennial.

In simple home gardening terminology, a perennial not only lives for more than two years, but does so without producing significant woody stems. Yes, this also happens to include palms and trunk forming yuccas (which are known as ‘perennial trees’), but that is another topic. Some perennials live only a few years. Some can live indefinitely by replacing their stolons, rhizomes, bulbs, tubers or whatever they regenerate from as their old growth gets left behind.

For example, bearded iris spread by fleshy stems known as ‘rhizomes’. As they grow from the forward tips, the older ends that get left behind will rot away. They are constantly replacing themselves, without leaving evidence of how long they have been doing so. (In other words, it is impossible to cut one down to count the rings.)

Many plants that are known as annuals are actually perennials, but get removed and replaced during their respective dormant season. Busy Lizzy can regenerate each spring if their roots do not succumb to frost in winter. Begonia, chrysanthemum, cyclamen and primrose are just some of the many other annuals that could technically survive as perennials.

Lily-of-the-Nile, African daisy, daylily, canna, penstemon, New Zealand flax and various grasses and ferns are some of the more familiar perennials. They are too diverse to generalize about, but happen to be among the most reliable of plants for bloom and foliage. Because form and mature size is somewhat predictable, properly selected perennials are unlikely to outgrow their particular situations.

This recycled article posted immediately after the article that was recycled last Wednesday, and similarly conforms splendidly to the Horridculture meme for Wednesdays. They originally posted prior to the invention of Horridculture.

P71206This is not a sequel to my rant ‘Real Deal’ from yesterday. It is just another rant. I should write more such rants; and I am actually considering designating Wednesday, as the day for discussion of the various hooey in horticulture, from some of the many fads and gimmicks to the lack of professionalism in the horticultural industries. Wednesday is the day between my current gardening column articles and the gardening column articles that are recycled from last year. There is certainly no shortage of hooey to discuss. I have been mostly polite about it so far. I sometimes wonder why I should bother with politeness. I sort of think that some would prefer more honesty than such unfounded pleasantries. Well, I can give more thought to that later. There are still a few more pleasant topics that should be discussed as well. For now, I will continue:

Weigela

Weigela can be bronze or variegated.

Stylish modern cultivars have been restoring the popularity of formerly common weigela, Weigela florida. Traditional sorts can reach first floor eaves, with delightfully open branch structure and rosy pink spring bloom. The foliage of most is variegated with white. Newer cultivars are more compact, with more variety of form, as well as of foliar and floral color.

Bloom can be pink, red, rosy red, white, white with yellow centers, or the the familiar rosy pink. Foliage can be green, bronze, deep purply bronze, or variegated with white or pale yellow. As it develops in spring, variegated foliage might be blushed with pink. Shrubbier modern cultivars may get no taller than five feet. Some are lower and densely mounding. 

Although deciduous, weigela are popular as short informal hedges. Formal or excessive shearing compromises both bloom and form. After primary spring bloom, several modern cultivars bloom sporadically later in summer. Weigela enjoys a bit of winter chill, so may not appreciate the mildest coastal climates. Partial shade is tolerable, but inhibits bloom.

Variegation And Other Foliar Color

Bright white variegation brightens shady spots.

Foliar color is not limited to autumn. Some deciduous plants display colorful foliage from spring to autumn. Then, some of these change color for autumn. Some evergreen plants display colorful foliage through the year. Variegation of foliage can be more colorful than associated bloom. So can unvariegated bronze, purple, red, yellow, blue or gray foliage.

All sorts of plants exhibit variegation or other variations of color of their foliage. They can be annuals, perennials, shrubs, vines, trees, or houseplants. Although many are popular primarily because of their foliage, some provide appealing bloom as well. Blue and gray foliage is a natural advantage in harsh climates. Other colors are selections of mutations. 

Because variegation deprives portions of foliar surface area of the chlorophyll needed to perform photosynthesis, it inhibits growth. This can be an advantage for plants that grow too vigorously otherwise. However, many variegated plants occasionally develop growth that is not variegated. If not removed, it can overwhelm and displace desired variegation. 

New Zealand flax, dracaena palm (Cordyline australis), gold dust plant, euonymus, coral bells and hosta are some of the many plants that are more familiar with colored foliage or variegation than without. If simple unvariegated coleus, croton or caladium are available, they must be notably rare. Blue spruce is always blue. Purple leaf plum is always purple. 

Although both gold and gray junipers are popular, the most common are green. Bronzed and variegated cannas are likewise not quite as popular as those with simple lush green foliage. Pittosporum tobira is so much more vigorous without variegation than with it, that the two distinct types of this same species perform different functions within landscapes.

Golden honeylocust supposedly produces lighter shade than darker green honeylocust. ‘Ruby Lace’, a bronze cultivar of honeylocust, supposedly produces faintly darker shade. Some golden or variegated foliage is more susceptible to scorch; although sun exposure enhances foliar color and variegation. Fresh new spring growth gets the best foliar color, but is likely to fade through summer.

Gemini

Robert Tomeo, my younger brother, is 53 years old today, and happens to be a Gemini (if that means anything). For the next month (less one day) we will be the same age. Not only am I a Cancer (if that means any more than being a Gemini), but I also have the distinction of being born during the Summer of Love in 1967! Anyway, this is one of the more mundane of my recycled articles that should have posted at noon on Saturday, but seemed to be more appropriate for June 13.

P80617Astrology is an interesting concept. It is amazing how accurate the various zodiacs are. In fact, they are so accurate, that all twelve of the zodiacs can apply to just about anyone, regardless of their respective birthday.

For example, Gemini people are gentle, affectionate, curious and adaptable. Well, who isn’t? If I told you that these traits applied to Leo, Aquarius or Sagittarius, would you believe me? The weaknesses of Gemini are nervousness, inconsistency and indecisiveness. We all of us experience these weaknesses at one time or another. Gemini people like music, books, magazines and strolling about town. What about Aries, Capricorn and Taurus? Don’t they? Are Gemini people unique in their dislike for loneliness, confinement or repetition? Probably not.

June 20 will be the end of Gemini. It will then be time for Cancer, with its set of distinctive traits, strengths and weaknesses.

The Good Weed

Only three years later, this tree is even more grand. It grows fast. Growth will decelerate as the tree matures, so that the tree should be with us for a good long time.

P80616KOnce in a while, a stray seed of a plant that would normally be considered to be an invasive exotic species happens to grow in a spot where it happens to fit. Those of us who regularly pull up unwanted feral seedlings, are typically skeptical. We probably pull up many such seedlings merely because we do not trust them, or because we do not want them broadcasting their seeds elsewhere in the neighborhood. In our region, Acacia dealbata, blue gum eucalyptus, black locust, pampas grass, broom, poke berry and Himalayan blackberry get no consideration; and their seedlings should be removed as promptly as they are discovered. English ivy does not get much more consideration, but every once in a while, it happens to wander into a situation where it is allowed to stay.

Catalpa is one that we are not quite sure about. It is an exotic species that happens…
