Sunday Best – Camellia sasanqua
Six on Saturday: Autumn Or Not?
Some vegetation is responding to cooler autumn weather as it should while some refuses to concede. Autumn foliar color is not so spectacular this season.
1. Canna musifolia, canna foliage is beginning to discolor in response to cooling autumn weather. I will groom such foliage out through the season until there is nothing left of it.
2. Plectranthus scutellarioides, coleus is not so easily convinced that it really is autumn. It is as vigorous now as it was for summer. I suspect that it will not last for long like this.
3. Cornus florida, flowering dogwood is already defoliated, and it did so quickly without much color. Others were somewhat more colorful, and were retaining their color better.
4. Acer palmatum, Japanese maple, like coleus, is not convinced that it really is autumn. This particular specimen is as green as it was for summer. Others are beginning to color.
5. Strelitzia nicolai, giant bird of Paradise supposedly blooms randomly. However, ours prefers to bloom through summer and finish about now, so is actually right on schedule.
6. Impatiens hawkeri, New Guinea impatiens, like coleus and Japanese maple, is not yet convinced that it is autumn. It will likely succumb to autumn chill when the coleus does.

Eastern Red Cedar
One of the less common and certainly least familiar of junipers happens to be the most culturally and environmental significant juniper in North America, even though it is not even known as a juniper. Juniperus virginiana is instead known as the Eastern red cedar. It has a vast range, including every state east of Colorado, as well as Quebec, Ontario and even Oregon to the west. In some areas within and near the natural range, fire suppression has allowed Eastern red cedar to become invasive.
Mature trees are mostly less than fifty feet tall, but are the biggest evergreen trees in Kansas nonetheless. The largest Eastern red cedars can get almost ninety feet tall. Most are well branched from top to bottom unless pruned for clearance. The fibrous bark is ruddy brown, but not often seed from the outside.
Foliage and fruit are rather variable. The prickly juvenile leaves of young plants and interior stems of mature plants can be rather annoying. The scale-like adult leaves are more typical of junipers. Male trees produce pollen that can be a significant allergen. Female trees produce sporadic, small berries in blue or purplish black, that are quite popular with certain birds through winter.
Prior to the discovery of the incense cedar in the west, Eastern red cedar was the common aromatic cedar that was used to make pencils and to laminate cedar chests and closets to protect woolens and natural fibers from moths. Since it is so repellent to insects and decay, it is commonly used as fence posts. Native American Indians also used posts of Eastern red cedar, painted red with blood of the animals they hunted, to mark the boundaries of their hunting ranges. The name of Baton Rouge, which means ‘red stick’, was actually derived from such marking posts.
During the Dust Bowl drought of the 1930s, and before becoming known as a potentially invasive species, Eastern red cedar was promoted by the Prairie States Forest Project as a resilient wind break. They tolerate drought, harsh exposure and inferior soil. They can be planted close together to fill out and gain height more efficiently. More information about Eastern red cedar can be found where I got much of this information, at the Great Plains Nature Center.
Chimney Clearance
There are several reasons why fireplaces are not nearly as commonly used as they once were. Modern building regulations have prevented construction of newer fireplaces (except pellet stoves). Many fireplaces that were ruined by the Loma Prieta Earthquake were never replaced; partly because there are other more efficient sources of heat, and partly because of the concern of air quality. The fuel that was once relatively easy to obtain from orchards that were getting removed to relinquish their land for urban development has been exhausted.
Regardless, those of us who use fireplaces need to be certain that they do not become overwhelmed by trees or climbing vines. Cypress, cedars, pines and some fan palms are remarkably combustible and hazardous when they get too close to chimneys, particularly if the roofs below are covered with old fashioned cedar shingles.
All trees and vines should be pruned away from chimneys so that they are out of reach of sparks and heat. The more combustible trees should get more clearance than deciduous trees (that are bare through winter) need. Nearby Monterey pines, Cypress and any trees that tend to accumulate debris should be groomed of debris, even if their limbs are already pruned back for sufficient clearance.
Trees should also be pruned for clearance from roofs and gutters; and any accumulated debris should be removed. Even before the weight becomes sufficient to cause damage, the motion of limbs in the wind is abrasive to roofs. Older roofs, particularly cedar shingles, will deteriorate under any accumulation of organic debris, particularly as it gets wet from rain.
Why Bother?
Nasturtiums were a good choice for my downtown planter box, or so I thought. I know that people pick flowers from such planter boxes. I figured that nasturtiums bloom so abundantly that no one could possibly pick all the flowers from them. Technically, I was correct. Technically, not all of the flowers were picked. However, there were times when only a few of the abundant flowers remained. I replaced them with some sort of compact aeonium like perennial that I can not identify. It forms dense mounds of yellowish green succulent foliage that I figured no one would bother. I do not mind when I notice a few pieces missing. There is enough to share. What I do mind is that someone clear cut harvested enough to leave this bald patch. The left half of the picture demonstrates what it should look like. What is worse is that there is so much of it extending outside of the railing that would not have been missed if it had been taken. Also, as the picture below shows, the more prominent common aeonium is not exempt from such pilferage. So, why do I bother? Well, I still enjoy my downtown planter box.
Norway Maple
It is rare now, but Norway maple, Acer platanoides, was once common as a street tree. A few are prominent within neighborhoods that were developed in the 1950s and 1960s. It resembles the common London plane. In fact, its botanical name translates to ‘maple like a plane tree’. Unfortunately though, the roots are perhaps too aggressive with pavement.
Norway maple defoliates somewhat more efficiently than London plane tree. However, in spring, it refoliates significantly later. Otherwise, it is a splendid shade tree. A few modern cultivars exhibit bronzed foliage that yellows for autumn. One exhibits variegated foliage. Another has chartreuse foliage. ‘Schwedleri’ was once the most common bronze cultivar.
Very few Norway maples are taller than forty feet within the mild climates here. They can grow significantly larger in cooler climates, such as the Pacific Northwest. Their palmate leaves are about five to nine inches wide. New trees are rarely available from nurseries, so require special ordering. Norway maple is not overly discriminating in regard to soils. It prefers regular irrigation through summer warmth.
Gutters Innately Accumulate Falling Leaves
Autumn foliar color gets messy. It is spectacular while suspended in deciduous trees and even on the ground. The problem is that it mixes with wind and rain as it deteriorates and gets sloppy. It necessitates raking from lawns, ground covers and hardscapes. It requires removal from gutters, or eavestroughs, and where it accumulates on roofs. It gets messy.
The timing could not be worse. The wind and rain that cause it to be so messy are no fun to work in. Using ladders to clean gutters and roofs is more dangerous in wet conditions. Fallen leaves are messier and heavier while wet. Yet, they are not too heavy for winds to blow green waste piles about after raking. Autumn weather will get progressively worse.
Unfortunately, gutters that accumulate fallen foliage require cleaning to function properly. Otherwise, foliar debris clogs them and their downspouts when they are most necessary. Rain water then flows over their edges and onto the ground below. It can be more than a minor annoyance. Splattering water can cause rot within adjacent walls that it dampens.
That is why old historic houses originally had ‘foundation plantings’ of dense vegetation. Some lacked gutters because gutters were very expensive. Instead, rain was allowed to flow from eaves and directly onto the ground. Dense vegetation between the dripline and the foundation contained the splattering. Almost all modern homes, though, have gutters.
Gutters may need cleaning more than once before deciduous trees defoliate completely. Evergreen trees necessitate cleaning as well, but do not shed so profusely for autumn. A few, such as redwoods and pines, are exceptionally messy. Because their mess may not coincide with autumn, cleaning it can be a bit earlier. It is easier during pleasant weather.
Cleaning gutters is a gardening task that may be best to leave for professionals. After all, it may involve climbing to unsafe heights on ladders and roofs. Installation of screen like devices over gutters can mitigate the need for future cleaning. Of course, gutters that are not below messy trees might never need cleaning. There are many variables to consider.
Sunday Best – Angel’s Trumpet II
Six on Saturday: Pots
Pots are a bit more common within our landscapes than they should be, but they can be justified.
1. Philodendron selloum ‘Lickety Split’ split-leaf philodendron grew efficiently enough to obscure its pretty green pot within a few months, but does not seem to grow much now. It seems to merely replace old foliage with new foliage. The stems do not elongate much.
2. Dianella caerulea, blueberry lily is named Sigmund because it looks like a shabby sea monster. It is in a large terracotta pot that it now completely obscures. It visually softens the blunt end of a low stone retaining wall that separates a few stone steps from a ramp.
3. Cymbidium, orchid with a few small bits of Vinca minor ‘Alba Variegata’, small white variegated periwinkle are in a cheap plastic urn, with Sigmund in the background to the left. I know neither the species nor the cultivar of the orchid, but it blooms white nicely.
4. Alocasia odora, taro, or whatever species this is, has grown quite nicely to obscure its pot, just like the split-leaf philodendron and Sigmund. It was taken from a vacated home with an Australian tree fern two years ago. Sadly, the old home will soon be demolished.
5. Brugmansia, angel’s trumpet really is getting to be redundant, but is also really quite pretty. Like the orchid, both its species and cultivar are unknown. I grew it from a scrap from a green waste pile in East San Jose. Its big terracotta urn was a gift a few years ago.
6. Eucalyptus globulus ‘Compacta’, dwarf blue gum is certainly not a typical houseplant. Yet, here it is within an antique coffee shoppe lounge at work. We do not know how long it can survive here without direct sunlight, but will eventually find out. It is quite grand.

Queen Anne’s Lace
There are actually a few different flowers known as Queen Anne’s lace. The most common species, Daucus carota, that has naturalized and even become somewhat of a weed in some areas, has two and a half inch broad, flat-topped trusses of delicately minute but abundant flowers, with a single red flower at the center of each truss. Apparently, Queen Anne pricked a finger with a needle while making the lace, leaving a drop of blood. Modern varieties have broader and fluffier trusses, often lacking central red flowers. They are a popular ingredient or fill for mixed bouquets with more colorful flowers.
The biennial foliage of Queen Anne’s lace grows to about three feet tall in the first year, with weedy but intricately lacy leaves. It blooms in summer of the second year. It is very similar to poison hemlock, which is poisonous enough to kill Nero, so should not be allowed to grow in vegetable gardens or where toxicity might be a problem; just in case.
