Six on Saturday: Too Much Autumn Color IV – Uncategorized Exotics

 

These are the last six of the twenty four pictures of autumn foliar color that I got before the rain knocked so much of the foliage to the ground more than a week ago. #2 is the only picture of foliage that is on the ground instead of still suspended on the stems that produced it. The fallen birch leaves were just too pretty on the stone wall to not get a picture of them.

1. Japanese maple is not my favorite species, but it does have certain attributes. There happen to be several at work just because they happen to work well there. Some that do not typically develop good color got remarkably colorful this year. I believe that this particular Japanese maple is the common ‘Bloodgood’. It had been dark reddish bronze through summer, and then turned brighter red for autumn.P81222

2. European white birch is grown for the elegant white trunks that contrast so nicely against the deep green of the redwoods. This autumn foliar color, although brief, is an added bonus. These trees were already starting to defoliate before the rain.P81222+

3. Hydrangea is not known for autumn foliar color, and as you can see, turns only pale yellow. Yet, it is striking in the shade, and contrasts nicely with the rich green of redwood and English ivy foliage.P81222++

4. Spirea is likewise not grown for autumn foliar color, or at least no so much in our mild climate. There are more than a dozen of them here, and none are doing very well. They will get cut back and groomed now that they are bare. I do not know what cultivar this particular spirea is.P81222+++

5. Golden weeping willow was not only golden with autumn foliar color, but is still golden with the yellow bark on the twigs. So far, I am not too impressed with the yellow twigs. It is still a small tree, and growing in a mild climate that may not stimulate much color. Regardless, I happen to like weeping willows. This one happens to be in a swampy spot where it is quite happy.P81222++++

6. Bald cypress is rare here, but there happens to be two at work. One was supposed to be a dawn redwood, but was obviously mislabeled. Fortunately, it just happened to be planted on the bank of a small creek where it gets plenty of water. The other was planted in an area that is too swampy for other trees. Both are doing quite well. When they defoliated, they covered the ground with finely textured needles that would have been impossible to rake up.P81222+++++

Six on Saturday: Too Much Autumn Color II – Natives & Exotics

 

Now we have a bit more variety than the last batch of six.

Red stem dogwood of the first and second pictures is the only species that is locally native. The California currant of the fourth picture, and the California black walnut of the fifth picture are both as native to California as the names imply, but are not native locally. The flowering dogwood of the third picture is from Eastern North America. You can guess the origin of the Chinese wisteria of the sixth picture, which happens to be the only vine represented in all four groups of six pictures.

The first three of the six pictures, or half, are of dogwood. The first two pictures are the only two in all four groups of six pictures that are the same species, namely red stem dogwood. Both were posted just to demonstrate that red twig dogwood, which typically turns only pale yellow like the foliage of the first picture, can develop a bit of red foliage like that of the second picture, if conditions are just so. Both the red stem dogwood of the second picture, and the flowering dogwood of the third picture, are the first two examples of red foliage from my four groups of six pictures. In the next two groups of six pictures, there is only one other example of bright red foliage, as well as an example of brown foliage, and an example of irregularly bronzed orange foliage. Those are topics for next week.

Six on Saturday: Too Much Autumn Color I – Natives

 

The merely adequate color among the sweetgums early in the season suggested that color would be insipid this year. Then, the weather did something that set it all off. There was too much autumn foliar color this week to select just six pictures. So, I didn’t. These six are only the first of four groups of six. It would not be practical to post a group weekly for four weeks, particularly since some of the colorful foliage in these pictures was dislodged by generous rainstorms shortly after the pictures were taken. There will be very little foliage left by the time the last group of six posts. Instead, two groups of six will be posted presently, and the other two groups of six will be posted next Saturday, before they are two weeks old. I hope this does not violate any rules.

All six specie in this first group happen to be locally native. They are also all yellow, which is the standard color here. Regionally, there is not much orange or red. The thimbleberry in the first picture is rather pale yellow, but that is more color than it typically gets. Of these six, the thimbleberry is also the only species that does not grow as a tree, or a shrub like the hazelnut of the second picture. The hazelnut happens to be a Western hazelnut. The cottonwood happens to be a black cottonwood, although I would not know what distinguishes it from any other cottonwood. The sycamore is more specifically a California sycamore, which really is quite distinct.

Six on Saturday: More Unknown Succulents

 

This is not as simple as it looks. It is something of a guessing game for me. I am rather certain that #1 and #2 are identified correctly. I am not so certain about #3 and #5. The name of #4 is merely a guess. #6 is the only one that I know the name of for certain, although the name that I know it as is now outdated.

The lack of a species name for the two species of Sedum #1 and #2 seems like a cop out to me. I might have discussed it in one of my Wednesday rants, or will do so soon enough. All species should be described as a ‘species’, not merely as a genus with a cultivar name tossed in as if it adequately designates the identity. I sometimes write about how the nomenclature of plants is like that of cars. Both plants and cars are distinguished by genus AND species, with some specie divided into separate cultivars and varieties. (Cultivars are merely ‘cultivated varieties’.) Depriving a plant of a species name is like describing a car as a Buick ‘Convertible’, or a Chrysler ‘Sedan’. There is a big difference between a convertible Electra and a convertible Skylark, although both are Buicks. There is also a big difference between an Imperial sedan and a LeBaron sedan, although both are Chryslers. I may not have identified the two Sedum with their correct names, but even their correct names are not very correct anyway.

Echeveria glauca #3 seems too simple. Shouldn’t it have a cultivar name too? I really do not know. I really do not even know what species it is.

The same goes for Graptopetalum paraguayense #4. Really, I do not even know what genus it is. This is merely a guess. How embarrassing.

Aloe brevifolia #5 has a different issue with its name. It seems that all aloes are known simply as Aloe vera, even though not many of us would recognize Aloe vera if we actually saw it. This makes it easier to identify unknown aloes, but complicates the identification of familiar aloes.

Then there is the easily identifiable Bulbine caulescens #6. Seriously, I recognize it, but somehow, the name got changed. The first name is how I know it. The second name is the newer correct name.

1. Sedum ‘Angelina’P81124

Six on Saturday: Fire Season

 

California really does have the same four seasons that the rest of America has. They just happen to be somewhat subdued in some of the milder climates. The rumor that California has only two seasons, summer and a few days of not-summer, is completely inaccurate. In fact, besides the traditional four season, we have a fifth season that overlaps at least summer and autumn. It reality, this season never ends. It is always ‘fire season’.

Like any other season, fire season affects how we garden here. We prefer to grow plants that are less combustible, which is often contrary to the preference for native specie. In suburban and rural areas, we must manage native vegetation and keep it away from our homes and other buildings. When the weather gets smoky from forest fires, some of us postpone gardening chores for healthier weather.

The Rincon Fire near Paradise Park (not to be confused with Paradise) burned for a few days a week and a half ago, and filled the Valley with thick smoke. By the time that smoke cleared out, smoke moved in from the Camp Fire that burned Paradise more than two hundred miles to the north. Smoke from the Woolsey Fire and the Hill Fire that both started on the same day in Los Angeles and Ventura Counties stayed to the south. The Bear Fire, which was the second relatively small forest fire in our region, started and was contained just yesterday, just a few miles outside of Boulder Creek. Most of us were not aware of it until after it was contained.

Incidentally, a 50% chance of rain is predicted for next Wednesday.

1. Clear blue sky finally appeared on Thursday morning.P81117

2. The orange moon demonstrates how smoky the sky was on the previous evening. It is not easy to zoom in and get a good picture of the moon.P81117+

3. Ponderosa pine forests are the more combustible parts of our region. The darker understory is a mix of coast live oak, canyon live oak, madrone and other chaparral flora. The dead ponderosa pine that I got a picture of for ‘Six on Saturday: Dia de los Muertos’ is to the right in this picture. Sunsets were spectacularly colorful before the smoke blew away. I can not explain why the color was so bland when this picture was taken.P81117++

4. Our debris pile continues to accumulate more biomass from the landscapes and surrounding forests. It is not yet big in this picture. It will get significantly bigger before it gets taken away. Once gone, we start the process all over again. It never ends. There is so much forest out there, and we are constantly trying to keep it away from the buildings.P81117+++

5. These numbers on the side of my work vehicle allowed the volunteer firefighter who used to drive it to go into areas that had been evacuated ahead of forest fires. Several of our vehicles are outfitted with these decals.P81117++++

6. This is the picture that you probably did not want to see. It is what remains of the home of one of my colleague’s clients in Malibu after the Woolsey Fire moved through. The front garden was exquisite. The home was even better.P81117+++++

Horridculture – Bad Name

51104Junipers have a bad name. So do eucalypti. Too many of the wrong types were planted back at a time when they were too trendy. Those that were planted into inappropriate situations grew up to cause problems. The names of all junipers and eucalypti are now synonymous with those problems, even though there are many types of both genera that are quite practical for landscape purposes.
Get over it.
There are many junipers and eucalypti that are very good options for some landscape purposes. They need only minimal watering once established, and many will survive with none at all when mature. Some types of juniper grow as very low and very dense ground cover. With proper pruning, others can develop as exquisitely sculptural shrubbery or even small trees. (Just do NOT shear them!) Because of their very complaisant roots, some of the smaller eucalypti work very well as street trees.
I am certainly not promoting either junipers or eucalypti. They will not work for every application. I am merely saying that they should not be automatically dismissed because of their names. They were once overly popular for a variety of reasons, and those reasons are still valid.
However, I will say that there are a few species and varieties of each that are worth avoiding. They are likely what originally justified the bad reputations that are now shared by all of their relatives. For example, blue gum eucalyptus that was planted as a timber crop so long ago really is MUCH too big and messy for home gardens. Even where space is sufficient, there are probably better options.
Some of the current fads are also worth avoiding, or at least questioning. Some are very likely to earn a ‘bad name’ in the future, either because there will be too many of them, or because their faults will become evident as they mature. Because so many get planted within such a short time, many that mature at the about the same rate will develop their faults at about the same time.
For example, crape myrtle is such a useful and complaisant tree that it has been planted too commonly for just about every situation in which a tree is desired. It is resilient. It is complaisant with concrete. It blooms spectacularly. It colors splendidly in autumn. It really is an excellent small scale or medium tree for small garden spaces or near utility easements. It works very well in narrow park strips where larger trees would displace concrete. Yet, despite all the attributes, it is not good for everything, and does not get big enough to become a substantial shade tree, as it so commonly gets planted for. In the future, there will be so many crape myrtles in so many of the wrong situations that they will be considered to be too common.
Queen palm is another example. It used to be somewhat uncommon and respected. Through the 1990s, big box stores were selling them like junipers and eucalypti decades earlier. They happen to be very appealing palms that are more practical than the formerly more common Mexican fan pale, but have become so common that they were very often planted into situations that they are not appropriate for. Those that are under utility easements will need to be removed when their canopies start to encroach into utility cables. Because they are palms, they can not be pruned around the cables. Those that are able to mature will outgrow the reach of those who maintain their own gardens, or typical gardeners, necessitating attention from more expensive tree services. Like crape myrtles, they will also lose their appeal in the future.70222

Six on Saturday: Tangly Cottage Gardening Journal

 

tanglycottage.wordpress.com is where you can find it. This is a blog about gardening, gardens, life, and of course, Skooter the kitty, in and around Ilwaco, in the very southwestern corner of Washington, where the Columbia River flows into the Pacific Ocean. Like so many blogs, it shares compelling insight about a culture and a region that might be very different from what one is accustomed to. Then again, it might be compellingly similar . . . or even unexpectedly familiar. You can decide for yourself.

I have been to Ilwaco only once, about twenty years ago. I spent the night in a campground there while driving from Silverdale, west of Seattle, to Saint Helens, north of Portland. It was certainly not a direct trip. That would have been a two and a half hour drive. I was on vacation, so drove around the Olympic Peninsula. I sort of intended on returning someday, but never did.

After all these years, it has been fascinating to read about the flora of the gardens of the region. When I was there, I was more interested in the native flora outside of town. Ilwaco still looks something like I remember it to look like, although I think that there is more landscaping downtown now.

A while back, I commented on Gladiolus papillio that was blooming in a planter box in downtown Ilwaco. I was impressed that it was such a reliable perennial species of gladiolus. I had been wanting to grow a species of gladiolus that was more perennial than than the common summer blooming bulbs that I am familiar with, but had not decided on which ones to try. Anyway, in response to my comment, the author of ‘Tangly Cottage Gardening Journal’ offered to send me a few of the bulbs! How could I refuse?

These six pictures are of those Gladiolus papillio bulbs that came from Ilwaco in Washington.

1. It is so excellent to get a package in the mail from such an exotic and far away place! It got here very fast. It was in my mail only two days after being postmarked on October 25.P81110

2. The contents of the package are even more excellent than the package itself! There were nearly fifty bulbs here! I planted them on the first of November, a bit more than a week ago.P81110+

3. The bulbs were planted in three groups of about a dozen, with two groups of about half a dozen between them. The first group is partly buried here because a bit of soil fell back into the hole before I got this picture.P81110++

4. This is how the same first group of bulbs looks completely buried. Aren’t they pretty? Never mind the calla. It is not vigorous enough to bother the Gladiolus papillio.P81110+++

5. This is the planting bed where the Gladiolus papillio bulbs were planted. They are up in back, in a row that extends from the left edge of the picture to the corner of the trellis with the espaliered camellia. The pinboard and mailbox in the top right corner of the picture are at the Post Office next door. I would have preferred to plant the bulbs in front of the Post Office, but there is no place to do so over there. I am pleased that these Gladiolus papillio were planted in a public space almost in front of the Post Office because that is where they originated in Ilwaco. As the proliferate, I intend to take a few to my downtown planter box in Los Gatos, and might even share a few with the lady who tends to the planter box next door to the Los Gatos Post Office.P81110++++

6. This is the Mount Hermon Post Office is next door.P81110+++++

Horridculture – Blame

P81106The response to the brief article that I wrote about the smoke from a small and localized wildfire on Sunday is not easy to dismiss. The original article is at https://tonytomeo.com/2018/11/04/smoke/ . It is about the smoke from the small and localized Rincon Fire, and goes on to discuss how the clear cut harvesting of redwood more then a century ago enhanced the combustibility of the forest. It was shared to Facebook, including the Facebook page of Felton League.

The article did not blame anyone for starting the fire. I read it again just to be certain. I said nothing about arsonists, the homeless, homeless arsonists, or anything of the sort! Blame, in regard to the Rincon Fire, is not relevant to horticulture, forestry, arboriculture or anything that I write about.

We all know that there are mentally ill people who are homeless because they do not function well enough to maintain a domestic lifestyle. Some are potentially dangerous because they can do things, such as start fires, without thinking about it. There are also those who can accidentally start fires as they are just trying to stay warm when the weather gets cold out in the forests where they live.

Do we really believe that blaming and vilifying the homeless or mentally ill helps? Chasing them from their encampments and farther out into the forests, as so many suggest, only increases the innate hazards by relocating them into areas that are more inaccessible and more combustible. If we really are so concerned, we should want such hazards relocated to more localized and accessible situations. The severely mentally ill who can not manage a descent lifestyle simply should not be homeless.

Furthermore, what about the vast majority of fires that are caused by electrical malfunction? Why are we not wanting to outlaw electricity? What about the fires that are caused by sparks from lawn mowers and weed whackers? Shouldn’t such machines be outlawed? What about forest fires that start as house fires? Should we blame those who live in homes? Who do we blame for all those combustible trees that grow wild in the forests?

I intend to resume writing mostly and perhaps nearly exclusively about horticultural topics after today. It is what I am qualified to write about. I apologize for this deviation. If I eventually establish a blog regarding homelessness, I will be sure to share a link to it here.

Six on Saturday: Dia De Los Muertos

 

Dia de los Muertos, or Day of the Dead, was yesterday, Friday, November 2. However, the dead are still dead. They don’t need a special day to be so. In fact, they do it every day of the year. Dia de los Muertos is just one day of celebration to honor them.

Dia de los Muertos is not for plants though. Dead plants just get cut down and disposed of. Some get composted. Dead trees get recycled into firewood. These are six pictures of five species of dead plants that I needed to contend with in the week before last.

1. Rhododendron. I really do not know what killed this group of rhododendrons. It is not uncommon for one to die. With all the rhododendrons in the landscape here, a few dead ones get removed annually. However, it is rather disconcerting that a few died all in the same area at the same time. All their dead stems were rather sculptural. They were removed just after this picture was taken. Of the five specie in these six pictures, this is the only species that is not native.P81103

2. Madrone. Bits and pieces of madrone commonly succumb to blight, sort of like fireblight in apple and pear trees. Sometimes, entire trees are killed like this one. It is fire wood now.P81103+

3. Ponderosa pine. The forest does not burn as frequently as it used to before people were here to extinguish forest fires. The lack of restorative fires interferes with regional ecology. Not only is the forest becoming congested with unburned fuel, but pathogens are proliferating in the aging flora and consequently accelerating the deterioration of the forest, which increases the combustibility. It is a natural process designed to correct an unnatural lack of restorative fires, but does not go well for those of us who live here. Ponderosa pines can live for a few centuries. However, in our compromised ecosystem, many succumb to pathogens while still relatively young. This one will need to be removed next year. Once dead, they deteriorate and start to drop limbs within the year.P81103++

4. Coast live oak. This is one of the most adaptable of tree specie in California. It lives right down to the beach, and into interior valleys, and up the summit of the Santa Cruz Mountains. It does what it must to adapt to the various environments within its range. It often lives in groves of the same, where it is more likely to burn every few decades or so. In spacious valleys, it is often not so social, with individual trees living in relative isolation from their neighbors. Grass fires can burn harmlessly between such trees, allowing them to live for a few centuries. Wherever they are, they develop more trunks than they need. As they mature, subordinating trunks like this one, get shed naturally and harmlessly. It is not as bad as it looks. In the wild, it would rot and fall to the ground as the rest of the tree continues on as if nothing happened. In our landscape, it was cut and taken away.P81103+++

5. Coast live oak. This dead foliage is a bit more alarming because I do not know what caused it. It is probably superficial damage caused by a girdling beetle. I did not look for evidence. Sudden Oak Death Syndrome is a much more serious disease that is all too common here (and a very sensitive subject). Fortunately, this particular specimen is a small and unimportant tree that I would not mind cutting down if it were to succumb. I just do not like to be reminded of how rampant Sudden Oak Death Syndrome is here.P81103++++

6. Tan oak. This tree really did succumb to Sudden Oak Death Syndrome, Phytophthora ramorum, which is more commonly known here as SODS or SOD. A few adjacent tan oaks that succumbed last year are already very deteriorated and will soon be dropping limbs if not removed over winter. These particular trees are not very important to the surrounding forest. Their removal will actually improve the collective landscape, and give the surrounding redwoods more space to expand. The problem with SOD is that we never know which oaks it will kill next. It kills trees before we know they are infected. There is no remedy.P81103+++++

Six on Saturday: Tequila

 

If one of these six different agaves happens to be the blue agave from which tequila is made, I would not know. I only know that all six are various specie or cultivars of the Agave genus. The sixth picture is that of the common century plant, Agave americana, which is not used for tequila. I have no idea what the other five are. The fifth looks like it could possibly be a picture of Agave victoriae, but if I remember correctly, I was specifically told that it is not.

All six of these agaves were procured by my colleague. The first specimen is still potted at the shops where we work. The second specimen was relocated into a new landscape early last spring. The other four are within minimal proximity of each other, in a more established part of the landscape. There happens to be two agave pups in the Infirmary Nursery. At least one is from the agave in the second picture. I believe that the second pup is the same as well, but it seems to be developing teeth.

The wickedly sharp teeth and spines of most specie of agave are the main reason that agaves are not more practical in home gardens or small landscapes. It is not practical to try to snip the terminal spines off, because more develop with every new leaf. If they get enough space out of the way, agaves are bold and remarkably striking big perennials that are very resilient to arid climates.

There are no captions this week, because I do not know what to say about agaves that I know nothing about.
