Six on Saturday: The Yard

 

This is no home garden. It is the yard outside the various shops of the Maintenance Department where I work part time. It contains some of the salvageable plant material that we try to recycle from some of the landscapes from which it must be removed. Over winter, some plants get dug and relocated directly, rather than come to the yard. Otherwise, plants come here to get canned (potted) to recover, and then find a home.

Because no one sees our yard, we need not maintain it like we maintain the rest of the landscapes. Consequently, it collects a few weeds. Also, because there are other shops in the same buildings, there are a few unexpected odds and ends left strewn about by other types of professionals, such as the electrician. Hence, #6.

1. You know, when I took this picture, I though that the annual grassy weeds somehow looked pretty in front of the wild cucumber vine on the cyclone fence. I’m not the artsy sort; so will not try to explain it.P90511

2. Mixed in with the wild cucumber vine, which incidentally makes not edible cucumbers, this potato vine blooms, but incidentally makes not potatoes. Of course, I never dug it up to confirm that claim.P90511+

3. This rose, which might be ‘Simplicity’, has been here for a few years. No one remembers where it came from. It was supposed to get planted into a landscape while it was still dormant. Too late now.P90511++

4. This rose might be ‘Medallion’, but it is hard to say for certain. It is not as big as it should be. It was supposed to get planted while dormant too. There actually is a landscape that can use both of them.P90511+++

5. Shasta daisy has been blooming for a while now. You would think that it would be easy to find a home for this one, but it is still in the yard. It is big enough to divide into more plants if still here this winter.P90511++++

6. Spring bulbs are done now.P90511+++++

Horridculture – Bad Pollarding And Coppicing

P90508Pollarding and coppicing are proper pruning techniques. If you think you are an arborist who believes otherwise, do not waste my time arguing about it. More than likely, you are neither as educated nor as experienced as I am with such matters, or you work exclusively with trees for which such procedures would be very inappropriate.
Well, yes, pollarding and coppicing are very inappropriate for the vast majority of trees and shrubs out there. Furthermore, even for those trees and shrubs that they are appropriate for, such procedures are very rarely done properly here in California. Most attempts at pollarding and coppicing are really horrid!
Take these blue elderberries and mock oranges for examples. They were mutilated last summer to improve the view of the historic Felton Covered Bridge. It sort of accomplished that objective, although the improved view of the Bridge was then cluttered with the disfigured and mostly bare trunks and limbs of the brutalized shrubbery below. Because they were chopped back too late in summer to grow much, they stayed that way until now.
So it is spring, and the shrubbery is growing from the tops of the mutilated but tall trunks and limbs, right back to obstructing the view of the Bridge. They will likely get chopped when they get to be too overwhelming, which again, will be in late summer, repeating the process. It would be better to just remove the shrubbery not only because it would be less work, but also because the shrubbery is so unsightly when it gets chopped!
OR; the shrubbery could get coppiced. Both blue elderberry and mock orange respond favorably to the procedure. If coppiced, or in other words, if pruned back to the ground annually each winter, they could regenerate fresh new growth each spring, but not get big enough to crowd the view of the Bridge by the following winter, when they get coppiced again. The elderberry would not bloom or fruit; but that is not important here anyway.
Coppicing takes advantage of the natural dormancy and regenerative processes of the plants. Starting over fresh each spring and growing uninterrupted through summer is more natural for them than trying to recover from getting brutalized while they are actively growing in summer. Since they start the process at ground level, they have room to grow without interruption. If cut back only as much as necessary, they have no room to grow.

Utilitarian Landscape

P90505I am no designer. I am merely a horticulturist. I grow things, and I know how things should be grown in landscape situations.

My colleague Brent Green is a landscape designer, as well as a horticulturist. He knows how things should be grown in landscape situations too, but more importantly, he knows how to assemble the landscapes that they grow in. He creates the sort of landscapes that most people think that all horticulturists strive for. (A few pictures of his home garden can be found in a former article, as well as another similar article that it links to: https://tonytomeo.com/2019/04/06/six-on-saturday-brents-garden/ .)

Brent and I have two completely different sets of standards for landscape design, to say the least. His ideal landscapes are very lush and inviting, with abundant color and fragrance. Mine are very simple and structured, with abundant fruits and vegetables. He strives to bring the ambiance of wild jungles into very urban settings. I try to instill formality and structure into the forests. Yet, we both agree that landscapes must be functional.

That means that landscapes must work for those using them, whatever they are using them for. Almost all of Brent’s clients use their landscapes as extensions of their homes, so want them to function as such.

I do not design landscapes, but I do happen to work in some. Most are in public spaces, and some are comparable to athletic fields. They function very differently from those in residential situations.

The unexpected way that these three small redwoods are functioning in this landscape was just too amusing to not get a picture of. I have no idea where all these wet suits came from, or why they are hung in this particularly prominent location, but it is the last thing I expected to encounter here.

The Other Rhodies

P90504KThere are countless species and cultivars of rhododendrons. Some have been in cultivation for centuries. Their big bold blooms are spectacular against a backdrop of their dark evergreen foliage. They prefer shelters spots, and some are happy to bloom in places that are too cool and too shaded for other flowers to bloom so well. They are so impressive that no one notices that they lack fragrance.

There is certainly a lot of variety among rhododendrons. Some are low mounding shrubs, while other can grow as small trees with open branch structure. Flowers can be white, pink, red, purple, blue or maybe even yellow or orange. Most flowers have some sort of pattern within the main color, but some are solid colors. Nonetheless, regardless of all the variety, we think that we can recognize a rhododendron when we see one.

Then there is Rhododendron occidentale, the Western azalea. The flowers are sort of recognizable as either big azalea flowers or lean rhododendron flowers, but are quite distinct from what we think of as familiar rhododendron flowers. The color range is very different too, with more white, marked with yellow, pink or orange. Even more surprising is that the bloom is quite sweetly fragrant!

Foliage is also very different from what is expected from a rhododendron. Not only is it deciduous, but if well exposed, it can actually develop soft yellow, orange or brownish red color in autumn. Individual leaves are rather narrow and papery.

We have only a few Rhododendron occidentale at work. They are not as tolerant of the partial shade from the redwoods as the more familiar rhododendrons are. However, they do happen to be blooming exceptionally well this year, while the bloom of the more familiar rhododendrons is less impressive than it has been in many years.

Six on Saturday: Rhody!!

P71014

This is not really about Rhody, the terrier whom I work for. I just threw that extra picture in because, if you know who Rhody is, you were expecting to see his picture after reading the title. The six pictures below are really just rhododendrons that were blooming last week.

Last year was the best bloom of rhododendrons and azaleas in many years here. Those who have known them for many years can not remember a more spectacular bloom, with so many of different cultivars of the rhododendrons blooming so profusely in the same season.

The bloom this year is unusually sparse. No one can explain it. They have good years and bad years, just like anything else in the garden. Fortunately, even in their bad years, the flowers that bloom are spectacular.

1. Of the six this week, this is my least favorite. It is a vary pale pink, but not pale enough to be white. There are not many florets on the trusses.P90504

2. I refer to this one as ‘Taurus’; but I really do not know what it is. ‘Taurus’ is very susceptible to thrip. This one sustains only minor damage from thrip, while a few others nearby are are seriously damaged.P90504+

3. This one may not look much better than #1, but the color is pinker, and the trusses are impressively big with more florets when it is in full bloom. It grows as a tree nearly twenty feet tall.P90504++

4. I refer to this one as ‘Anah Kruschke’, but like for #2 above and #5 below, I am not sure about its identity. ‘Anah Kruschke’ should not be damaged by thrip as badly as this one is. I think my colleague grew this one.P90504+++

5. Of the three here that I have names for, this is the one that is most certainly not what I like to think it is. ‘Helene Schiffner’, which happens to be one of my favorites, is not blushed with yellow.P90504++++

6. I believe that my esteemed colleague grew this one as well as #4. I remember delivering a significant order of rhododendrons here years ago, at about the same time this and #4 were installed.P90504+++++

Horridculture – Bad Seed

P80317+California poppies are like no other wildflower. They are so perfectly bright orange, and look almost synthetically uniform in profusion, as if painted onto coastal plains and hillsides. They may be a bit more yellowish in some regions, or a bit deeper orange in others, but they are always bright and strikingly uniform.
Genetic variation is naturally very rare. I can remember hiking with my Pa up to the (lesser known) Portola Monument in the hills behind Montara, and finding a few pale white poppies, and even fewer pale purple poppies. It was like finding four leaf clovers! Genetic variants among California poppies are not quite as rare as four leaf clovers are, but finding a few of both white and purple was really strange. I never found a pink one though.
Nowadays, poppies can bloom in all sorts of shades and hues or orange, yellow, red, pink and soft purple, as well as creamy white. Some bloom with fluffy double flowers. Of course, all this variety is not natural. California poppies were bred to do this.
The potential problem with such breeding is that California poppy is naturally very prolific with seed. Any of these weirdly bred varieties could escape into the wild and interbreed with wild poppies, causing them to be more variable, and interfere with the ecosystem.
The problem is not just with California poppies. Many plants get bred extensively enough to interfere with how they behave in the wild if they happen to escape cultivation.
Fortunately for California poppies, the weird new varieties do not really get very far in the wild. The are not true-to-type, so revert back to their original bright orange in just a few generations, even without outside influence. If pollinators do not recognize their unfamiliar color and form, they are less likely to get pollinated to continue to tamper with the ecology. In fact, wild California poppies still have the advantage in that regard.
This yellow California poppy with an orange center is a second generation seedling, and is already halfway between the original yellow variety, and the wild orange.

Redwoods Are So Tall . . .

P90428Redwoods are SO TALL!
How tall are they?
They are so tall that you can see for yourself if you look in this direction . . . from anywhere in North America.
They are so tall that if you need firewood, I can aim one in your direction as I cut it down.
They are so tall that while they drop foliar debris on the Ford and Chevrolet parked below, they also drop foliar debris on Mercury and Saturn in their respective orbits.
They are so tall that while other trees collect kites and Frisbees, they collect airplanes and satellites.
They are so tall that only a few of their seed survive. Most burn up in the atmosphere on their way down.
They are SO BIG too!
How big are they?
They are so big that some have tunnels cut through them so cars don’t run out of gasoline while driving around.
Okay enough of that for now.
Most of the biggest redwoods here were harvested, leaving only stumps to remind us of how big they were. The few trees that were big enough for harvest a century ago, but were not harvested when those around them were, probably exhibited some sort of defect that made their lumber undesirable.
The tree in this picture happens to be one of the few that is big enough now to suggest that it was likely big enough for harvest when those around it were harvested. The trunk is more that six feet wide. Yet, except for the severe lean, no obvious defects were observed. (The vertical edge of the doorway to the left was included in the picture for comparison with the lean of the tree.)
The tree started to lean only recently. If it had taken several years to develop this lean, the top several feet of the trunk would be curved upward, as it would have continued to grow vertically away from gravity while the trunk below it moved. If it moved suddenly but only once several years ago, there would be a kink near the top of the otherwise leaning trunk, from which, subsequent growth would be vertical.
This tree instead leans with a straight trunk from bottom to top, which means that it grew vertically, and then moved into this diagonal position too recently for new vertical growth to develop. Lateral branches are also diagonal, as they maintained their position perpendicular to the trunk. Although redwoods rarely destabilize, this one really seems as if it is about to fall.
Is this destabilization relative to some sort of deficiency that prevented the tree from getting harvested a century ago? I really should investigate.

Mellow Yellow

P90427KThis picture of a yellow Pacific Coast iris probably should have been incorporated into the Six on Saturday post earlier today. I omitted it because I was not so impressed with how the color showed up. It is really more yellow than it looks. In this picture, it looks more like a discolored version of the white Pacific Coast iris. This sort of variation, that might have been normal for old fashioned photography, is not expected of digital imagery.
It sort of reminds me of how some insects and other pollinators see flowers so differently with infrared or ultraviolet. Are infrared or ultraviolet faded in digital imagery as well? It would make sense, since there is no need for normal cameras to record colors that we can not see. Nor is there need for computer monitors to display such invisible colors. Ironically, modern technology can modify color to make that which in invisible to us visible.
Modern technology is always improving the quality of stored data, and the presentation of such stored data. Perhaps there really are ways to take pictures that record infrared and ultraviolet, although I can not imagine why there would be a use for such technology. Video is good about recording and presenting motion. Audio records and presents sound. Regardless, none of it is good enough to keep us from actually enjoying our real gardens.
Pacific Coast iris blooms in all sorts of weirdly bright colors now. Modern technology has certainly had its way with them as well. The flowers are bigger and bolder than they naturally were. The foliage is greener and fluffier. Yet, to me, the best are still those that grow wild and bloom on the coast of San Mateo County, with unassuming flowers in subdued shades of greyish blue, like faded denim.

Six on Saturday: Above And Below

 

Flowers are almost everywhere this time of year. Even some of the lawns are blooming with English daisy. Warm season annuals are starting to bloom nicely while a few cool season annuals that have not yet been replaced are still going. Although those that were established before this spring finished a while ago, a herd of daffodils that got planted very late last winter are just now finishing bloom. New flowers start bloom as old flowers fade.

I got these pictures of some of the more perishable blooms while I could, so some are already outdated. #1 was actually already fading before last Saturday, but I had other pictures to show at the time. #2 lasted only a few days because it is still recovering from getting relocated in the warmth of last spring, after it had already foliated. Of these only #3 and some of 4, 5 and 6 are in good bloom now, but they do happen to be quite spectacular.

Flowering cherry, star magnolia and flowering dogwood are small or mid sized trees that are above the low Pacific Coast iris below; hence ‘Above and Below’. (However, this particular star magnolia is only about four feet tall so far.) I can only identify the cultivar of the ‘Kwanzan’ flowering cherry. The rest are identified only by species.

Incidentally, there is far more above all of this that is not seen in these pictures. Almost all of the ‘biomass’ here is suspended by the grand but remarkably blandly blooming redwoods.

Horridculture – That’s Just Swale

P90424Building and environmental codes are so ridiculous. So much of what I would want in my home is now illegal. So much modern technology that I do not want is now required. Fireplaces and wood stoves are not allowed. Overly elaborate electrical systems to serve every room are necessary. I would prefer a technologically simple home comparable to those built more than a century ago, but am prohibited by law from ever constructing one.
The area outside of a home is no easier to work with. Dead trees inhabited by the wrong sorts of woodpeckers can not be cut down. Excavation can be prohibited if a particular beetle happens to be in the way. Even some of the increasingly combustible trees and overgrown vegetation have more rights on my land than I do. Now, I am a horticulturist; so I know more about vegetation management than the treehuggers formulating these laws.
Even some of the weather has more rights than people do. In some municipalities, rain that falls onto a property has the right to percolate into the soil. Rain water that drains from roofs and pavement must be provided with ‘swales’ or basins where it can do so. It can not be evicted into old drainage systems that drain into local creeks and rivers. However, such rain water must not be detained in tanks for use in the landscape through summer.
The picture above shows part of a new landscape in the middle of a new parking lot at a newly constructed building. It looks simple for a reason. It is a pair of swales. The meadow grasses conceal a pair of surprisingly deep ditches on either side of the central walkway. Rain water drains here to percolate into the ground. The soil below the walkway might have been replaced with coarse gravel to promote drainage into that area as well.
Do not park a car at the curb and try to step from the curb into a swale to get to the walkway! You could get hurt. As I mentioned, that grass is concealing ditches that are deeper than they look. It is safer to walk through the parking lot to a large paved patio like area that is out of view behind where the picture was taken from. The other option is to walk away from the building to the far end of the walkway, but really, who would do that?
Why is the walkway even there? I really don’t know. There are no curbs on it, so anyone in a wheelchair who feels so compelled to go to the far end to use it could get seriously hurt by tumbling off the edge while trying to get out of way of someone going the opposite direction! The swales are snares for walkers and baby buggies too. Perhaps the walkway is merely bait. What are the surveillance cameras really for? What sick entertainment!
