Morning Glory

90807A landscape designer would have more fun describing both the modern and the good old fashioned varieties of morning glory. Their vivid colors are so resplendent. Their rich green foliage is so luxuriant. Their delicate vines are so elegant. Hey, perhaps this is not so difficult. Anyway, the popular garden varieties of morning glory are descendents of various species of the genus Ipomea.

Except for a few obscure types, and the perennial blue dawn flower, popular garden varieties of morning glory are surprisingly complaisant annual vines, which grow from seed sown at the end of winter. Without getting too invasive or weedy, they sometimes reseed where they get watered, although they might revert to a more feral state after a few generations, or after the first generation.

Some varieties of morning glory have the potential to reach single story eaves, although most stay a bit lower, and some varieties do not get much higher than a doorknob. They work well on small trellises, or even simple stakes, and are just right for picket fences. The simple two or three inch wide flowers are rich hues of blue, purple, red, pink and white, some with spots, stripes or streaks.

Docile Annual And Perennial Vines

90710Most of the familiar vines really are exploitative bullies. They shade the same trees and shrubs that they climb for support. Some will even strangle and kill those who make it possible to get where they want to be. If they do not find trees or shrubs to victimize, they are likely to climb walls and ruin the paint, stucco or siding. Their aggressive nature can be a problem in landscape situations.

Fortunately, there are several vines that are not so aggressive or destructive, such as mandevilla, lilac vine, star jasmine and Carolina jessamine. Other vines that are even more complaisant are light duty perennials and annuals that might grow like weeds while the weather is warm, but then do not have enough time to grow too big or do much damage before they die back through winter.

If flashy color is not important, vining vegetable plants such as pole beans, cucumbers and peas, can cover fences very nicely. On flat fence surfaces, such vines will climb string strung in a vertical zigzag pattern between a horizontal row of protruding nails at the top, and another similar row at the bottom. Unsightly cyclone fences are even better, but will need be harvested from both sides.

Although it is too late to sow beans and cucumbers, a new phase of peas can be sown in mid summer for production in autumn. Fragrant and subtly colorful sweet peas, which are grown for their flowers rather than as vegetable plants, take considerably more effort here. They get started in autumn for the following spring. Trailing nasturtium can get sown at any time, for summer or winter.

As the name implies, perennial pea is a perennial that can get almost rampant, but dies back by autumn.

Passion fruit vine can either be a perennial that dies back to the ground in winter, only to regenerate the following spring, or a somewhat woody vine with wiry stems that survive for several years. Those that retain their vines through winter can get cumbersomely big, or can alternatively be cut back severely late in winter, to behave almost like more docile types that die back for the winter.

Workday

Felton League is another blog that I sometimes share articles from here with. This is the first article from Felton League that got shared here. It is more about ‘Workday’ that was posted here earlier.

tonytomeo's avatarFelton League

Workday at Felton Presbyterian Church, from eight to noon on Saturday, July 27.

Yes, that was yesterday. I would have written about it earlier, and in time to plan for it; but I was just informed about it less than a day earlier, on Friday morning. Fortunately, plenty of parishioners attended and got quite a bit done. In the future, we will need to be more diligent about announcing the workdays at lunch on Tuesdays. Even though some of us who attended more regularly in the past are no longer here, there are newcomers.

The biggest project was the removal of those rotting benches on
the northern half of the patio out front. The sturdy posts that
supported them for all these years were surprisingly sound, and the
last few needed to be pulled out by a pickup with a tow chain. It was
a mess, but worth the…

Workday

P90728Without prior notice, I was informed on Friday morning of a workday on Saturday morning at Felton Presbyterian Church. That was yesterday. Since there was no time to get other chores done in advance, I was an hour late. Considering that we only work for four hours between eight and noon, one hour is rather significant. I felt compelled to attend regardless. A few friends who are parishioners of Felton Presbyterian Church appreciate it.
The difficulty of not attending is that there are several other volunteers who do attend, and they all have very different ideas, or no idea at all, about how to accomplish what needs to be done in the landscape. It is amazing how much damage can be done with a few light duty power tools and too much undirected ambition. Even when I am there, it is difficult to convince the others that I know more about horticulture than all of them combined.
For the past several years, I had been pruning a flowering crabapple tree to renovate the branch structure that was mutilated by someone with loppers and power hedge shears. Yes, hedge shears. I had pruned the tree for clearance above a parking lot on one side, and a patio on the other, but with low branches in between to partly obscure the view of parked cars from the patio. Bloom was spectacular, and not compromised by the pruning.
Then I missed a workday. Even though the flowering crabapple tree did not need to be pruned at that time, someone lopped away the lower limbs indiscriminately, and then sheared the top! There were mutilated stubs all over the new exterior of the canopy. Much of the blooming stems for the following season were removed. It was very disappointing to see all of my effort wasted so pointlessly. Now, I need to start the whole process over.
However, when I got there today, a planter box below the crabapple tree was being dismantled and removed. I could not work in the area, so must return to start the process of renovating the crabapple tree. Realistically, it should be done while the tree is dormant in winter, even if it compromises bloom for the following spring somewhat. The tree is so gnarly and congested now that it is unlikely that anyone would notice a few less blossoms.
As frustrating as it can be, we actually get quite a bit done. These lily-of-the-Nile in the picture above were one of our projects many years ago. They were recycled from a garden in Aptos from which they needed to be removed. We split, groomed and plugged them. Most were promptly removed and discarded by someone else who did not realize that we had just installed them. But hey, at least these few survived and continue to bloom.

Pasadena Windstorm

P90727K

The weather in the parts of California that most of us are familiar with is generally rather mild. Some of the hottest temperatures every recorded were in the Mojave Desert, but not many of us even know how to get there. Some of the heaviest snowfall ever recorded was near Tahoe, but many of us think of that as almost Nevada. San Jose, Los Angeles and the most populous regions enjoy mostly comfortable weather throughout they year.
‘Drought’ is often an inaccurate description of the naturally prolonged dry chaparral and desert weather, as if it is abnormal. There would be no chaparral or desert if it rained here as much as it does in other climates. What is considered to be normal rainfall in some regions would be disastrous to regions that do not normally get so much precipitation. Drought does happen here sometimes, but it is not as common as outsiders believe it to be.
Once in a while, we get something that really is strange. The floods and mudslides of the Winter of 1982 were disastrous. The wicked frosts of late 1990 were the worst in recorded history, even though they would not have been much of a problem in most other climates farther inland. On the morning of December 1 in 2011, Pasadena and the surrounding regions of the San Gabriel Valley experienced historically strong and destructive winds.
When I went to Los Angeles shortly afterward, I was amazed to see that pieces of the glass facades of some of the skyscrapers had been stripped away. Thrashed fronds of queen palms hung limply as if a hurricane had gone through. My colleague got these startling pictures of destroyed Canary Island date palms, which are famously resilient to wind, in Leimert Park, about fifteen miles southwest of Pasadena.

Six on Saturday: Bad Neighborhood

 

My six pictures for today are not from any of the landscapes. Nor are they from my garden. They are not from the forests or parks or other people’s gardens either. That is nothing new. I sometimes get my pictures from some rather randoms situations. These six are a bit more random than just average random though. They happen to be from around the big compost piles, where we dump some of our green waste and horse ‘fertilizer’.

This is the same compost pile where where the ‘Good Weeds‘ grow. Yup, good weeds from the bad neighborhood.

The first #1 is exotic. The second #2 and the third #3 are assumed to be native, but might possibly be exotic. The others are quite native.

1. Mullein – is a naturalized exotic species. It does not seem like the sort that would naturalize. To the contrary, is seems to be quite docile here. It is sometimes left in gardens where it self sows, just because it is appealing.P90727

2. Unidentified – but believed to be native, these tiny silvery white flowers are not as pretty as they are up close in this picture. I just happen to like them. I think I studied it in school, but just I can not remember what it is.P90727+

3. Bull Thistle – is not so easy to distinguish from other similar species. I do not even know if this is the native bull thistle. The prickly scales are not as straight as they should be. It is the only one that we now as such here.P90727++

4. Yerba Santa – seemed to be more purplish when I took this picture. The foliage looks grungy to me, as if sticky with honeydew and a bit of sooty mold. That is natural for it, and may explain why it is an unpopular native.P90727+++

5. Sticky Monkey Flower – has a funny name. It is native, but the sticky monkey that it is named after is not. It gets a bit shabby if allowed to grow wild in home gardens, but can be improved by aggressive winter pruning.P90727++++

6. Evening primrose – is not the same as the common yellow evening primrose that is familiar elsewhere in America, although I really do not know what makes it so special. Another species has smaller pastel pink flowers.P90727+++++

Fan Flower

60727Only a few flowers are true blue. A few more are nearly blue, but slightly blushed with lavender. Of the latter group, fan flower, Scaevola albida, which is usually more lavender than blue, can be quite convincingly blue if conditions are just so. The semi-circular flowers (which are actually wide bilateral flowers) are most abundant in spring and summer, but can bloom sporadically all year.

The finely textured evergreen foliage is dense enough to function as light duty groundcover. Mature plants eventually get about four feet wide without getting deeper than a foot, and more typically stay less than half a foot deep. Outer stems pressed into the soil with their tips up should root and grow into new plants. Fan flower prefers regular but moderate watering. Shade inhibits bloom.

Fan flower only became available in the middle of the 1980’s. How appropriate for flowers of such distinctive style and color! The original common type is still the most reliable. Newer cultivars are not quite as resilient, and might not be as vigorous either. However, they are worth growing for their bigger and bolder flowers, and because they cascade better from pots or raised planters.

To Mulch Is Not Enough

60727thumbMost plants would prefer the real thing; how they do it in the wild. They drop their leaves, flowers and twigs. Deciduous plants do it mostly in autumn. Evergreens might spread it out through the year. The debris accumulates on the ground below, and decomposes at about the same rate as it accumulates. There is no one there to clean it up. Yet, the natural ecosystems know what to do.

The plants that produce the debris use the nutrients produced by its decomposition. So, with the help of the many microorganisms in the soil, they recycle their own trash. To exploit this resource most efficiently, feeder roots tend to congregate near the surface of the soil where the nutrients are. Because the debris also insulates and shades the soil surface, roots are comfortable there.

Densely forested ecosystems produce the most debris. Many smaller plants in such ecosystems may disperse their roots exclusively into decomposing debris without reaching into soil below. In desert ecosystems, where such debris is minimal, roots are mostly dispersed much deeper to avoid the hot and dry soil surface. They wait for recycled nutrients to leach to them through the soil.

Redwoods, cypresses, many pines and most eucalyptus produce unusually thick layers of debris that decompose slowly. This technique inhibits or prevents the germination of seeds of potentially competitive plants. So, in other words, these trees and other plants had this, as well as moisture retention, soil insulation and nutrient recycling, all figured out long before we knew about mulching.

After we put so much work into raking and disposing of foliar debris that would otherwise accumulate in our gardens, it is ironic that we sometimes need to apply seasoned mulch to compensate for the lack of organic material on the surface of the soil. (Unseasoned mulch draws nitrogen from the soil to sustain its own decomposition.) It does more than merely improve the appearance of otherwise exposed soil. Mulch helps unnatural landscape environments function a bit more naturally.

Horridculture – Fruit Theft

70726thumbGrowing fruit trees is quite a bit of work. While producing, some of the fruit trees need nearly as much attention as annual vegetable plants in the vegetable garden. Then, while dormant, they need meticulous and specialized pruning. Some fruit trees get damaged by insect or disease infestation, or severe weather. Some fruit can get taken by wildlife. Yet, for most of us, the reward of fresh fruit is worth all the hard work that goes into growing it.
Unfortunately, most types of fruit, especially the stone fruits, ripen simultaneously within their respective seasons, and are suddenly and briefly too abundant to be consumed while still fresh. Unless shared very efficiently with plenty of friends and neighbors, some of the fruit must be canned, frozen or dried for later consumption. Then, as suddenly as it started, the season for the particular type of fruit is done. There will be no more until next year.
That had never been a problem us, even though some of the fruit trees produce quite a bit. There was one particular summer, about 2004, when we were expecting an unusually abundant crop of unusually big peaches. We got all the jars out and cleaned on Friday afternoon. All the big pots and utensils that we would need for canning were out on the counters. We must have purchased ten pounds of sugar, and even got some pectin for jam.
Early on Saturday morning, we went out to collect the peaches while it was still cool, and found them GONE! It was as if they had never been there. All the work of pruning and pampering the tree was for NOTHING!
Now, I know that when I was a kid, we shared abundance with neighbors. We children were expected to take brown paper grocery bags of produce to neighbors who lacked the trees for particular fruit. For example, I delivered cherries to those who lacked cherry trees. I delivered apricots to the few who lacked apricot trees. Neighbors sometimes stopped me on the road to give bags of fresh produce for my parents or other neighbors.
Also, I know that there was nothing wrong with taking a few fruits from a neighbor’s tree. We often went behind the Charles Residence to get a few oranges when we got out of school. We sometimes got apples from the back yard of the Richmond Residence. Of course, we first asked if we wanted more than a few for a recipe or something. No one really minded because the system was respected, and none of the trees were exploited.
That was a long time ago. By the time I was in high school, we started hearing about fruit trees getting stripped of every last bit of fruit while no one was around. Over the years, it became progressively common. Some neighbors had me cut down fruit trees from their front yards because there was no point in all the maintenance if they could not get fruit from them. It was saddening, wasteful, and so contrary to our formerly idyllic lifestyle.
When it happened to the peach tree that I had taken such good care of in the garden next door, I was furious! What made it even worse is that we knew who did it! The so-called ‘gardener’, who was supposed to ‘maintain’ ONLY the front lawn stopped by the prior evening, just after I checked on the fruit. I sort of wondered why he was there so late, and why he was in back, but gave it no more thought than that.
He later told me that no one wanted the fruit, and that it was just going to fall on the ground and go to waste. Really, I would not have minded if he had taken a few peaches. I would not have minded if he had taken several or even most if he had asked before we got ready to can them. It would have been better for someone or several someones to enjoy them fresh than to can them as surplus.
About a year and a few months or so later, the fig tree in my back yard was stripped by the so-called ‘gardener’ who supposedly ‘maintained’ the landscape next door on the opposite side of where the peach tree lived. There had been no preparation to dry the figs yet, since I had planned to leave them on the tree a bit longer. Also, there was not as much fruit as there was on the peach tree.
The theft of the fruit was not the worst of the problems in this situation. The main problem was that the tree was so severely damaged in the process. I had pruned the tree so meticulously for several years, both for good (late crop) production, and also for clearance above a parking space. I did not mind the slightly elevated canopy; but the guy who stole the fruit without a ladder broke the limbs so that he could get the higher fruit!

Iochroma

90731It is gratifying to see renewed interest in this old fashioned flower. Naturally occurring varieties of some of the nearly three dozen species of Iochroma were popular decades ago. Some might actually be naturally occurring hybrids that have yet to be identified. Many modern cultivars (cultivated varieties) were intentionally bred or hybridized for more compact growth and profuse bloom.

Old fashioned varieties of Iochroma are occasionally seen as large rampant shrubbery or even small trees in old established landscapes. Modern cultivars are more compact and manageable. For the fullest and most vigorous growth in summer, they can be pruned aggressively as winter ends, but should otherwise be pruned only for shape and confinement. They should never be shorn.

If Iochroma resembles angel’s trumpet, it is because they are related. The foliage is very similar, although the leaves are smaller. The narrowly tubular flowers are much smaller and clustered. The hummingbirds who like them so much do not even need to reach their beaks all the way in. Bloom is purple, blue, red, pink or maybe white or yellow. Iochroma happens to do well in partial shade.
