When a tree falls in the forest, and there is no one around to hear it, does it make a sound? Of course it does! There is just no one to hear it. Why should that be such a profound question? A falling tree makes a mess too. Anyone who does not see or hear it in action can witness it afterward. Sometimes, roots that were inadequate to support the fallen tree become exposed as well.
There is certainly nothing unnatural about trees falling in forests. Otherwise, forests would be too crowded for new trees or anything else to inhabit. The roots of fallen trees might have been adequate for many decades or centuries, but eventually succumbed to decay and the weight of the canopies they supported and sustained. Trees falling in home gardens are completely different.
Domestic trees (in home gardens) are likely to land on homes, cars, other…
There are mixed emotions about tree removal permits that so many municipalities need to issue in order for a ‘heritage’ tree to be cut down legally. Most of us want to believe that in America, we have certain rights to do what we want to on the properties that we own. Obviously, that makes the most sense. However, if it were that simple, many more prominent trees that are collective assets to the larger communities would be removed.
As an arborist who writes the reports needed to procure these permits, I see it both ways. There are many trees that are worth preserving for the Community, and there are probably many more that must be removed for the safety of those who live around them. I sometimes hear of common homeowners who get fined for removing a tree without a permit, just because they were not aware that it was…
Where winters are cooler, zonal geranium, Pelargonium X hortorum, performs as a warm season annual. It is perennial only with shelter from frost. Locally, traditional cultivars are so reliably perennial that they can get congested without thorough pruning and grooming after winter. Frost occasionally ruins outer growth, but rarely kills entire plants with roots.
Modern cultivars bloom more profusely and more colorfully than old cultivars, but are not quite as resilient. They are more likely to rot during the damp and cool weather of winter. They bloom exquisitely from spring through autumn though, with bright hues of red, pink, peach, salmon and white. They stay lower and more compact, so require less grooming.
The more popular modern zonal geraniums should not get much more than two feet high and wide. Their small flowers bloom on globular floral trusses that can get as wide as six inches. Traditional zonal geraniums get bigger, with smaller floral trusses. Nearly circular and aromatic leaves generally exhibit darker halos between lighter centers and margins.
Green is the most common floral color. It only seems to be rare amongst flowers because almost all green bloom relies on wind for pollination. Thus, neither color nor fragrance is useful to get the attention of pollinators. Actually, green flowers do not get much attention at all. They are easy to ignore in the wild, and generally unpopular within home gardens.
Most showy green flowers such as zinnia, chrysanthemum, hydrangea and gladiolus are progeny of unnatural breeding. Showy but naturally green flowers such as hellebore and orchid are merely incidentally green, as they employ infrared or ultraviolet color to attract pollinators. Although people can not see infrared or ultraviolet color, many pollinators do.
After all, flowers bloom only for pollination. Many customize color as well as fragrance to appeal to preferred pollinators. They are merely incidentally appealing to people as well. People breed flowers to be more appealing to people, even if unappealing to pollinators. Nonetheless, even breeding is limited to characteristics that initially attracted pollinators.
It is impossible to identify the most common color among flowers that rely on pollinators. Pollinators are regional. Therefore, red and orange flowers may be more common where hummingbirds who prefer red or orange are more common. Purple flowers may be more common where bees or certain butterflies who prefer purple are the dominant pollinators.
Yellow seems to be the most common natural color of flowers of North America. Red and orange are very common as well. Although common, pink is merely a tint of red, so is not a real color. Neither is brown, which is a shade of orange. Although very common among flowers that rely on wind pollination, it is quite rare among flowers that rely on pollinators.
Blue is the rarest natural floral color. Many flowers that seem to be quite blue are actually purplish. Purple is uncommon, but not as rare as blue. Ultraviolet and infrared get almost no consideration since they are invisible to people. However, both are common amongst most showy flowers, particularly white and maybe red flowers. Red is invisible to insects, though infrared is not.
Batman and Robin were here!
. . . well, not quite. It is decoration for summer camp. We never know what we will find in the landscapes that we maintain here. Those who work at camp arrive before guests, so that they can get ready, and of course, to decorate. Guests only started to arrive two weeks ago. It makes our work more interesting, as we try to work around the traffic and events, but it is SO gratifying to see so many guests enjoy the facilities that we maintain! Those who work at camp enjoy being here too. It is obvious in all the work they put into preparation. It gets pretty wild and colorful, as I was reminded when I found what had been done in a grove of coast live oak just outside of one of the main auditoriums. Last year, I pruned and groomed the trees…
Incandescent light bulbs were the standard form of electric lighting for more than a century after their invention. It took a while for fluorescent and halogen lamps to become popular; and by the time they did, high intensity discharge (HID) lamps had already become available. Nowadays, light emitting diode (LED) lamps seem to be replacing all sorts of electric lighting.
For a brief time in the late 1980s, high intensity lamps that were being used for large scale applications and street lamps became a fad for exterior household lighting. They worked nicely for driveways, so many of us believed that they would work just as nicely for night lighting of home gardens and patios. By that time, most of us had realized that the sickly yellowish glare of the sodium vapor type of high intensity lamps that were so common as street lamps was not at all appealing around the…
The biggest lawn where I work for part of the week was formerly a pond. It was installed above an extensive drainage system to compensate for the natural saturation of the soil. A relatively small pond remains at the lowest corner of the large lawn to contain some of the runoff, which gets pumped back onto the lawn for irritation. However, this pond had drained and became overwhelmed by vegetation many years ago. Only recently, after the removal of the overwhelming vegetation, the pond was restored by the simple closure of its drainage gate. It is developing into a different sort of riparian ecosystem from what it was for the past several years, which was different from what it was before that.
1. Cattail and Himalayan blackberry overwhelmed this area many years ago. We knew it as the corn dog orchard because of the cattail bloom. This is what remains of the cattail.
2. Cottonwood appeared several years ago. They grew in a small grove of several slender trunks, perhaps from a single root system of a primary tree. These two are flooded now.
3. Knotweed proliferated on the margin of the newly flooded pond. Some got submerged where it grew while the water was lower. I hope that it dies like the submerged bramble.
4. Weeping willow enjoys the swampy situation here. The newly flooded pond might not bother it much. The soil is naturally saturated within a minimal depth from the surface.
5. Water lily seems happy here too, although one of the six that were installed is missing. One specimen has about twenty leaves. I could not take a picture of it without reflection.
6. Fountains are supposed to dissuade proliferation of mosquitoes. I do now know what to think of it. Everyone else (except mosquitoes) likes it though. That is more important.

Pink, 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…

The 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…
The easier name is ‘dawn redwood’. I just used the big and fancy Latin name because that is how landscape designers with something to prove say it. If the big name does not impress clients, an explanation of how rare it is, and that it is one of only a few deciduous conifers, will likely do the job. Even back when it was still a fad, I got the impression that was its main function; to impress clients.
It is not even a particularly practical tree. If it gets too big for its situation, it is difficult to contain without disfiguring the canopy. Because the priorities for most were conformity to a fad and to dazzle a client, not much thought went into their appropriateness to their respective landscapes. Consequently, many went into landscapes that were not big enough for them. Although deciduous, dawn redwood does not even get good…
