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+++++

Scented Geranium

60511Window boxes were supposedly invented in Venice to contain aromatic plants that repelled mosquitoes (and probably because garden space was so minimal in Venice). Hanging plants like nasturtium and ivy geranium are traditional window box plants because they do not obscure scenery or sunlight. Scented geraniums are also popular because they are be so strongly aromatic.

Scented geraniums are of the Pelargoniuim genus, so are related to ivy and common geraniums, but are a mix of a few different specie and hybrids. Their foliage can smell like rose, lemon, orange, apple, strawberry, ginger, mint or other herbs or spices. Specialty geranium growers may have nearly a hundred varieties to choose from, which is less than half of the known varieties.

Not many scented geraniums bloom with impressively colorful flowers. However, many have interestingly textured, colorful and lobed foliage that might be velvety or even raspy. The more compact varieties stay less than a foot tall, and spread laterally very slowly. Others have longer but limber stems that lay low as they spread like sloppy ground cover. A few stand upright as tall as five feet.

Fire Is Part Of Nature

P81106Plants have very different priorities from those who enjoy growing them. The colors and fragrances of flowers that we find so appealing are really designed to guide pollinators. The appealingly aromatic foliage of scented geranium and other herbs is actually designed to repel hungry insects and animals. Many tasty fruits are designed for seed dispersion by animals who enjoy them too.

Pollination, dispersion of seed and self defense are all part of what plants do in nature. They must also know how to survive in their respective natural environments. Many plants survive cold arctic weather. Others survive arid deserts. Many native plants want a bit of water through winter, but know how to survive through long dry summers. Many or most natives know how to survive wildfires.

As unpleasant as it seems to us, wildfires are very natural here. Native plants lack the mobility to get out of the way, so use other techniques to survive. A few, such as the two specie of redwood, survive by not being very flammable. More know how to resprout from their roots after they burn. Even more simply regrow from new seedlings. Then there those that use fire to their advantage.

Monterey pine trees tend to accumulate combustible debris. They also produce more seed-containing cones as they age and deteriorate. When they burn, all the debris burns so hotly that most of the other competing vegetation gets incinerated. However, the dense cones of Monterey pine protect the seed within, only to open to disperse the seed afterward. It is a rather ingenious plan!

Ungroomed desert fan palms burn at least as hotly, but survive because the hefty trunks protect the buds within. Each technique works for the specie that use it, but is not safe for home gardens! This is why combustible vegetation needs to be managed around the home. The rules are different in urban areas than they are where wildfires are a concern, but they are important everywhere. Even the most combustible of native plants, as well as exotics, can be reasonably safe with proper pruning and maintenance.

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.

Wax Begonia

90515Oh, how breeding complicates things. Many years ago, there were only six basic types of wax begonia, Begonia semperflorens-cultorum, with three choices for floral color, and two choices for foliar color. Bloom was white, pink or red. Foliage was either green or dark bronze. Although these choices have not changed, some modern hybrids are difficult to distinguish from other species.

Wax begonia can be either a cool season annual or a warm season annual, depending on when it gets planted. It can be grown as a short term perennial if pruned back in both early spring and early autumn. By spring, winter growth is tired of the cold. By autumn, summer growth is worn out from warmth. Exposed plants can get lethally frosted in winter or roasted by sunlight in summer.

Therefore, wax begonia prefers to be somewhat sheltered. It is more tolerant of full sun exposure in summer if mixed with other annuals or perennials. Too much shade compromises bloom. Wax begonia expects richly amended soil and regular watering, and is just as happy in pots as other annuals are. Potted plants can be moved to sheltered spots when the weather gets too hot or cold.

Nomenclature Is More Than Botanical

90515thumbSimply put, ‘nomenclature’ is how things get named. It is not exactly like naming a child or a dog, or even a new small country in the South Pacific. There is a certain technique to it that is more like naming cars. Well, it ‘was’ like naming cars, a long time ago when cars had simple names rather than numbers and letters. Coincidentally, nomenclature of plants is getting to be just as confusing.

Plants and other biological organisms are assigned Latin names, which for plants, are also known as botanical names. These names are universal, for everyone, everywhere in the World. Almost all plants also have common names that are more or less regional. That is why what is known as Norway maple here is known as sycamore in England, but both are Acer platanoides everywhere.

The first part of a Latin name designates the ‘genus’, which is the more ‘general’ of the two parts of the name. (genus = general) For example, all true maples, including those that are known as sycamores in England, are within the same genus of ‘Acer‘. Genus names are like ‘Buick’, ‘Oldsmobile’ and ‘Pontiac’ for cars. They distinguish a general group, but are no more specific than that.

The second part of a Latin name designates the ‘species’ which is the more ‘specific’ of the two parts of the name (species = specific) For example, within the genus off Acer, the Norway maple is designated as Acer platanoides. Species names are like ‘Electra’, ‘Riviera’ and ‘Skylark’ for cars. They designate specific cars within the big general group that is collectively known as ‘Buick’.

There are of course more general and more specific classifications as well. Just as Buick, Olsmobile and Pontiac are within the group known as General Motors, the genus of Acer is within the family known as Sapindaceae along with Aesculus (horse chestnut) and Litchi (Lychee). ‘Schwedleri’ is a cultivar (cultivated variety) of Acer platanoides, just as some Buick Electra are ‘Limited’.

Incidentally, rules of proper nomenclature dictate that Latin names are italicized, and that the genus name is capitalized, while the species name is not.

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+++++

Santa Cruz Island Ironwood

60504A few years ago, it was known as Santa Catalina Island ironwood. However, the rare subspecies native to Santa Catalina Island lacks the distinctively angular foliar lobes of the Santa Cruz Island ironwood, Lyonothamnus floribundus ‘aspleniifolius’. The evergreen compound leaves are about five inches long and four inches wide with three or five narrow leaflets, and look like chicken feet.

Young trees can grow at an impressive rate, but rarely get to thirty feet tall, which is only half as tall as they get in the wild. Most stay rather narrow, and shorter than a two story house. They work nicely in groves, but not as symmetrical groupings. Each tree has a unique personality and form, and some stay smaller than others. The finely shredding bark fades from cinnamon brown to gray.

Six inch wide trusses of tiny white flowers bloom late in spring or early in summer. These circular trusses are flattened, similar to those of toyon but larger. They fade to brown and can hang among the foliage for years. Older trees bloom more than vigorous young trees do. Deteriorating older trees can be cut to the ground and allowed to regenerate with fresh new growth from their stumps.
