Six on Saturday: Bark

 

Rhody said, “Cornus florida bark is rough.” He likely intended to say, “Dog would bark, ‘ruff!’.”

This is not about Rhody though. It is about these six pictures of bark of some of the more significant trees that I work with. All are native here. Only the sycamore was installed intentionally into a landscape. All of the others grew wild. There are so many interesting trees here that it was not easy to limit these pictures to just six. I actually took more pictures that were omitted.

Furthermore, a picture of Rhody is not included.

1. Platanus racemosa – California sycamore is bigger and bolder than other American sycamore. Trunks of mature trees are massive and gnarled, with this distinctively blotchy gray bark.P00613-1

2. Pinus ponderosa – Ponderosa pine is the grandest of pines. The massive trunks seem to be comparable to those of Douglas fir. Bark often flakes in bits that resemble jigsaw puzzle pieces.P00613-2

3. Quercus agrifolia – Coast live oak is second only to valley oak in regard to grandeur. Unlike valley oak, it is evergreen. Smooth gray young bark eventually becomes darker and furrowed.P00613-3

4. Pseudotsuga menziesii – Douglas fir is the majestic State Tree of Oregon, and a main timber crop there. Locally, it mixes with various ecosystems. Corky bark is rather finely furrowed.P00613-4

5. Acer macrophyllum – Bigleaf maple is the most imposing maple of the West. As the name implies, the leaves are bigger than those of any other maple. Bark gets sort of checked with age.P00613-5

6. Sequoia sempervirens – Coastal redwood is the grandest of all, and it happens to be the tallest tree in the World. Also, it is the state tree of California. The ruddy bark is distinctly fibrous.P00613-6

Post Script: For the first time, I am violating the recommended limit of six pictures to include this extra (but unnumbered) picture of Rhody for those who would be otherwise disappointed.P00613-7

Fan Aloe

50610
Some aloes should have more fans.

most aloes are tough perennials that do not need much water. Unfortunately, they do not have many fans. Maybe that is why fan aloe, Aloe plicatilis, makes it’s own. The plumply succulent leaves are distichously arranged, which is a fancy way of saying that they are either to the left or to the right, flaring out to form foliar fans.

Individual leaves are just as distinctive as their arrangement is. They are not tapered and pointed like those of other aloes. Instead, they are about an inch and a half wide from end to end, with weirdly blunt tips. They get almost a foot long. The soft gray color contrasts nicely with coral flower spikes that bloom at the end of winter.

It grows slowly, but fan aloe is one of the few aloes that eventually grows into a big shrub with several sculptural trunks on a flaring base. In their native habitat in South Africa, old specimens grow as small trees more than ten feet tall. Branches that need to be pruned away can be rooted as cuttings after the cut ends dry out a bit.

Summer Vegetables Like Warming Weather

Summer Vegetables Like Warming Weather

Tomato, pepper and eggplant plants should be out in the garden by now. They typically get planted only a few weeks after the last threat of frost, so that they can start to disperse their roots early. Growth above ground accelerates as the weather gets warmer. Fruit develops and ripens through summer.

These three types of vegetable plants get planted as seedlings for two main reasons. First, when they go into the garden, seedlings are bigger and more established than seeds that need to take time to grow are. Secondly, the cost of the few plants needed for an average garden is not much more than the cost of seeds.

Now, zucchini, melon and summer squash can be done either way. Not many plants are needed, so the expense of seedlings is minimal. However, seedlings are a bit more fragile than those of tomato, pepper and eggplant. Seeds grow so efficiently that they get established almost as readily as seedlings do, so are just as practical.

Regardless of how they get planted, the weather has been so odd this year that there has been only minimal advantage to planting seedlings and sowing seed on time. Tomato, pepper and eggplant plants that were planted early may not be much more mature than what could be planted now. Harvest will be delayed either way.

Bean, cucumber and corn all grow best from seed. Seedlings take more time to recover from transplant than seed take to germinate and grow. Besides, so many plants of each type are needed that seedlings would be expensive. A single package of seed is cheap and goes a long way, so is probably sufficient for an average garden.

Corn is one of those vegetables that produces on a rather tight schedule. Seed that gets sown at any particular time matures at the same rate, so that all the fruit finishes at about the same time. This is why corn gets sown in phases. If timed properly, a subsequent phase begins to produce as the preceding phase gets depleted.

Winter squash, including pumpkin, are similar to summer squash, although they are more tolerant of unusually cool spring weather. They too can either get planted as seedlings or sown as seed. They take their time to produce fruit that ripens by autumn, so have more time to catch up.

Horridculture – Spruce Up

P00610
Even Charlie Brown would reject this little blue spruce.

No one wants to cut down this little blue spruce. What is worse is that no one wants anyone else to cut it down either. We all know it is ugly. We all know that it can not be salvaged. We all know that it really should relinquish its space to the healthy and well structured coast live oak next to it, in the lower left of the picture. Yet, it remains.

It was planted amongst a herd of gold junipers in about 1980 or 1981, shortly after the construction of the adjacent buildings. An abandoned irrigation system indicates that it was likely irrigated for some time afterward, although it is impossible to know for how long. Otherwise, it and the junipers were completely ignored for the last four decades.

When the vegetable garden was installed nearby, brambles, weeds and trash that had been accumulating for forty years was removed from the area. A few of the most decrepit junipers that were not worth salvaging were removed too. The young and feral coast live oak that grew next to the spruce should have been removed as well, but is actually in very good condition.

Furthermore, the coast live oak is a better tree for the particular application. It is native, so does not mind neglect. The spruce was never really happy there, which is why it is so puny and disfigured now, with the lower two thirds of the trunk bare of limbs and foliage. Obviously, the spruce should be removed so that the oak can continue to develop as it should.

We just like the spruce too much to remove it directly. Even though it would look silly if the bare trunk were exposed by the removal of the oak, the bit of foliage on top is so pretty and blue and familiar. I mean, it looks like we have a spruce in the yard; and everyone likes a spruce!

The plan is to subordinate it to the oak. As the oak grows upward and outward, the lower limbs of the spruce will be pruned away to maintain clearance. Eventually, the spruce will look so silly that the landscape would look better without it, and we will not mind cutting it down so much. It will be unpleasant, but it will be better than interfering with the development of the oak.

Rat Tail Cactus

00617
Not many cacti cascade from planters.

When first imported to Europe from the Americas, cacti were very strange. Their distended green stems do all the photosynthesis. Vestigial leaves develop into sharp protective spines. Vestigial stems develop into more formidable thorns. One of the first cacti imported is among the weirdest. Rat tail cactus, Aporocactus flagelliformis, develops pendulous stems that do not stand upright.

In the wild, rat tail cactus cascades from rocky ledges and crotches of trees. In home gardens, it cascades splendidly from elevated planters or hanging pots. Pruning scraps make good cuttings to plug into loose stone or broken concrete retaining walls. Rat tail cactus likes warmth, but also some partial shade from hot afternoon sunshine. Yellowish stems appreciate a bit of mild fertilizer.

Old stems grow longer than three feet if they get the chance. However, they discolor with age. Pruning them out from the base promotes healthier and more compact growth. Most stems emerge from the base, with minimal branching beyond the base. Bloom is slightly purplish pink. Individual flowers are about two inches long and slightly wider than an inch. They last for three or four days.

Hanging Planters Need Extra Attention

00617thumb
Some plants cascade nicely from pots.

With few exceptions, plants dislike confinement of their roots. They prefer to be in the ground where they can disperse roots freely. Houseplants stay potted because of a lack of other soil inside. Some plants live in pots for portability. Some plants just happen to look good in pots. Plants in hanging planters conform to any combination of these and other reasons. They serve their purpose.

Most hanging planters are simple pots suspended by three wires, chains or strands of plastic, jointed at a hook or loop. The hook or loop hangs from a hook affixed to a ceiling, eave, rafter, beam or tree limb. Hanging baskets are pot-shaped mesh or metallic baskets outfitted with fibrous lining to contain the medium within. Small plants or cuttings can grow from holes cut through the lining.

Of course, hanging planters for houseplants are generally pots instead of baskets, which are too messy for inside. They are likely also outfitted with big saucers for drainage. Hanging planters just happen fit well into spaces that are not useful for much else, such as up near a ceiling in a corner. Many of the most popular houseplants just happen to cascade splendidly from hanging planters.

Portability is another advantage of potted plants. Hanging planters that contain frost sensitive plants outside can spend winter in sheltered situations. Orchids and epiphylums that are prominently displayed during bloom can return to less prominent spots when finished.

Hanging planters are popular mostly because some plants simply look better in them. Cascading houseplants like Boston fern, pothos and spider plant, might look a bit mundane on flat surfaces. Many low growing bedding plants are more impressive if suspended at eye level than they are in the ground. Some bedding plants and small perennials excel at cascading from hanging planters.

However, hanging planters are very different from the ground. Because of limited root dispersion, potted plants rely more on regular watering than those in the ground. Because they are exposed to open air, they dry out fast, so crave more water.

Dago Wisteria

P00607
All this bloom will eventually be fruit.

My colleague down south and I have completely different gardening style. He is a renowned landscape designer, so his home garden is as elaborate as the landscapes he designs for his clients. I am primarily a farmer of horticultural commodities, so my home garden is very strictly utilitarian, with few items that are grown just because they are pretty.

My colleague’s garden is outfitted with a very well built pergola over the patio at the rear of the home. Six common Chinese wisteria were installed to climb the six supporting post and sprawl above. Their cascading spring bloom is both spectacular and alluringly fragrant.

Of course, when I saw that pergola while the wisteria were still young, I thought that it would be ideal for Dago wisteria, which most of us know simply as grapes. They climb like Chinese wisteria. They bloom with somewhat pendulous floral trusses that . . . sort of resemble wisteria bloom. Although they lack color and fragrance, they provide an abundance of fruit.

Now I get to work with some real Dago wisteria. It was planted years ago by someone who did not stay to maintain it. It got rather overgrown and gnarly before I pruned it into submission. Without a pergola, I extended vines from the rail fence that the main vines climb, over to a banister on the upper floor of an adjacent building. It works something like a pergola.

Because I do not know what cultivar of grape the vine is, I do not know what pruning technique it prefers. I happened to leave long canes last winter, just because they reached the banister on the opposite side so well. Now, the bloom is so profuse that I am concerned about the weight of the subsequent fruit pulling the rail fence over!

Hieroglyphs

P00606K
“111”? . . . “777”? . . . “TTT”? . . . “LLL”?

What does this mean? Is it ‘111’ deprived of the lower serifs? Is it ‘777’ with abbreviated arms? . . . ‘TTT’ lacking right arms? . . . ‘LLL’ with abbreviated legs? Is it pointing toward something important? Is a hieroglyph from an ancient language . . . or a language that has yet to be invented?! Is it like a miniature crop circle pattern cut into wood by Sasquatch or extraterrestrials?!

The arborist who left it here after cutting down the deceased ponderosa pine that formerly stood where this large stump remains might be amused to read that I contemplated it so intently. Actually, I did not really contemplate it so much. I only wrote about it as if I did because it is amusing to do so. I have no idea what this hieroglyph represents. I know that it is not important.

I have worked with enough respectable arborists to know that some of them prefer to leave their distinctive marks on the stumps of some of the impressively large trees that they cut down. In many of the suburban regions in which I work, most of such stumps get ground out shortly afterward. In the forested rural area here, such stumps remain until they rot and disintegrate.

On rare occasion, I encounter a familiar hieroglyph or the initials of a respected colleague. Now that we are as old as we are, familiar hieroglyphs are increasingly rare. Arboriculture is for the young. I sometime wonder about those who leave unfamiliar hieroglyphs. To me, the continuation of the tradition seems to indicate that they enjoy their work as much as my colleagues did.

That is important in horticultural industries. There are few in society who understand the appeal. We do what we do because it is what we enjoy.

Six on Saturday: Leftovers

 

It is not easy to discard seedlings and cuttings that have potential. We are supposed to sow several seed for vegetable plants where we ultimately want only a few, which typically produces a few extra. Feral seedlings for other types of plants commonly appear in the garden. I happened to grow a few seed that were marginally old, but that I did not want to discard. Nor do I want to discard deteriorating but lingering cool season annuals from last winter.

1. Since no new warm season bedding plants are going into the landscapes, cool season bedding plants are lingering until they succumb to the warmth. This pansy is not ready to give up yet.P00606-1

2. ‘Roma’ tomato seedlings that got plucked to favor stronger seedlings got plugged in cells for later. They got sown very late, and plugged even later, but might become a nice second phase.P00606-2

3. Extra summer squash seedling were also too good to discard. The main plants are producing now. This one should find a home quick. Since it can produce all season, no phasing is needed.P00606-3

4. Ponderosa pines make extras too. This seedling got plucked along with other weeds, but was too exemplary to discard. (For the record, someone else salvaged it; so I can not be blamed.)P00606-4

5. This is too blurry and dinky to look like much, but is a seedling of California fan palm. The seed was so old that I doubted its viability. I am very pleased with it, even if is the only survivor.P00606-5

6. White California poppies are rare in nature. This one was left in the landscape while many of the orange poppies were removed along with weeds. There is another only a few yards away.P00606-6

Zinnia

50603
zinnia

The lineage of modern zinnias is too complicated to describe. Most are still known as Zinnia elegans, even though they have been bred extensively with several other specie to produce an impressive variety of flower forms and colors. The shortest varieties get only a few inches tall. Big varieties get about two and a half feet tall.

The two to five inch wide flowers, which bloom in phases from spring until autumn, can be yellow, orange, red, purple, pink, salmon, peach, chartreuse or bronzy brown. Some are striped or freckled.

Some flowers look like colorful daisies, with big petals (ray florets) neatly and flatly arranged around prominent centers (disc florets). The overly abundant petals of pom-pom types make rounded blooms with nearly obscured centers. Most are fuller than the daisy types, but not as plump as pom-poms.

Zinnias are warm season annuals that like good exposure and rich soil. The paired leaves are slightly raspy, like kitten tongues, and can be susceptible to powdery mildew. Deteriorating flowers should be deadheaded, although a few can be left for seed.
