Some Edible Plants Start Out Toxic

41126thumb
Pokeweed is both edible and toxic.

Early American settlers from Europe had a lot to learn about the plants of North America. After their first harsh winter without much food, many were eager to eat the first fresh greens of spring, which was sometimes the very poisonous jimson weed. Those who were not lethally poisoned right away might have hallucinated and told their friends that they could fly, and consequently got burned as witches.

It should be no wonder that some early Americans were hesitant to try tomatoes, which are related to jimson weed. Potatoes are also related, and their fruit, foliage and stems actually are toxic. Pokeweed (unrelated) was probably riskier, since the same young shoots that can be cooked as greens become toxic as they mature. Their poisonous berries, which were used as ink back then, look delicious.

There were other potentially dangerous edibles brought from Europe and other places as well. Rhubarb, which makes such great pies, is petioles (leaf stalks) for toxic leaves. Both American and European elderberries are slightly toxic before getting cooked into jelly or pie. Elderberry juice must be cooked and then given yeast to make wine. Figs and mulberries can be eaten right off their trees, but their sap is caustic enough to be irritating to the skin.

The seeds of apples, pears, peaches, nectarines and apricots can be toxic if too many are eaten. They are not a problem only because they are not eaten. However, apricot kernels can be roasted and eaten like almonds because the cooking process denatures the toxins. Separating the small kernels from the hard shells is much more work than it is for almonds, but they supposedly have great flavor.

Just like for apricot kernels, pokeweed and elderberries, the heat of cooking makes taro edible. The foliage can be eaten as stewed greens. The big and starchy corms (bulb-like stems) are something like potatoes. All parts of taro are toxic while raw. There are actually a few toxic plants that are edible once cooked. For a few others, it is important to know what parts are edible, and what parts are toxic.

Horridculture – Dumpster View

P00722
Location – Locations – Location

Rather than addresses, most of the guest cabins at the conference center where I work for part of the week, have delightfully horticultural names; such as Camellia, Lupine, Holly, Dogwood, Huckleberry, Strawberry and Cottonwood. Others have names that are suggestive of idyllic locations, such as Meadowbrook, Creekwood and Rustic Dell. Then, . . . there is ‘Dumpster View’.

Dumpster View is not actually a guest cabin, or a lodge, or any building that any of the guests would ever see. It is part of our maintenance shops buildings. Although large, these building are outfitted with only a few windows. The largest building has only a single window for an office. The smaller building has only four windows. Two of the windows have a view only of dumpsters.

The picture above shows the view from the window in the galley. It was what I saw as I made coffee for the crew in the mornings back when we all were still working. As many as fifteen big dumpsters have congregated in that herd, right outside, beyond the spider plant. Because the area is a paved driveway with significant traffic, I can not even plant a tree to obscure the view.

No amount of houseplants bigger than the spider plant can obscure this view without becoming obtrusive. Hanging pots outside the window might detract from the outer scenery, but would require more attention than I want to devote to them. Curtains would be the most practical solution, but would get grungy in this particular situation. Besides, no one else here really notices.

Horticulture is not for everyone, and can not fix everything. No one stays in the shops buildings long enough to notice how horrid the views are anyway. We all leave to go to work in scenery that others vacation in.

Bad Wine

P00719
I believe that this is a young Chilean wine palm, although I am not certain.

Italian Americans, particularly Californians, are expected to be experts in regard to wine. I am not. I can not explain it. I dislike wine, especially the best of it. It smells and tastes like rotten grapes. When I learned that Chilean wine palms were, and might still be, decapitated for the collection of their sap, from which wine is made, I learned yet another reason to dislike wine.

This little Chilean wine palm, Jubaea chilensis, pictured above, lives just a block or so away from the bad date palm that I wrote about last Sunday. No one here will try to make wine from its sap. The utility cables that seem to be too close in the background actually pass with plenty of clearance to the right, so will not be a problem in the future. This young palm should be safe.

Although I have encountered too few of the species in my career to be completely certain that this little palm is a well bred Chilean wine palm, it is very convincing. I see no indication that it is a hybrid of another species. About half of the Chilean wine palms that I encounter are hybrids. Most of these are hybrids of queen palm. Others are hybrids of pindo palm. Both look weird.

Of course, well bred Chilean wine palms are not much better. The specimen pictured below demonstrates that, regardless of how bold and striking they are, they are still rather weird palms. That is probably why they are so rare now. They were rare even during the Victorian Period, when weird species were trendy. Yet to many, their distinctive weirdness is part of their allure.

I can not help but wonder where this Chilean wine palm came from. Someone must really appreciate it to put it here.

Chilean wine palm is not a good houseplant.

Fine China

P00718K-1
Before: There was not much hope for the Chinese maple underneath this mess.

It will be just fine. The Chinese maple that I mentioned earlier this morning sustained surprisingly minimal damage when part of a bay tree fell onto it. The situation initially seemed hopeless prior to the removal the heavy debris that was pressing the diminutive Chinese maple downward. Yet, the little tree somehow regained its composure, and is expected to recover.

The little Chinese maple was always rather sparse in the shade of the surrounding forest. Also, it exhibited an asymmetrically sculptural form. That is likely normal for the species within its natural environment, where it lives as an understory tree (within the shade or partial shade of larger forest trees). The distinctive form and open canopy were part of its allure.

As the debris was removed, most of the stems of the Chinese maple sprang back into their original positions. Only two major limbs were fractured and needed to be pruned away. Some of the minor twiggy growth was groomed in the process. The main trunk was somewhat destabilized, but not too detrimentally so.

It probably should be no surprise that the little tree was so resilient to the altercation. It is, after all, an understory tree. Within its natural environment, it likely contends with the same sort of abuse. Chinese forests are likely just as messy as forests here are. Gravity pulls all that mess in the same direction.

The little Chines maple may not look like much now that it has been groomed and pruned to be even more sparse than it originally was, but it should be fine. By this time next year, foliar density should be comparable to what it was prior to the incident. The form will remain sculptural, as it grows away from the shade of the forest, and out over the stream below.

After: After a bit of grooming, this little Chinese maple is not so badly disfigured.

Six on Saturday: Timber! III

At the end of May, Six on Saturday – Timber! II, ended with a precariously disfigured bay tree. Timber!, on May 10, mentioned that most of the tree had previously broken apart and fallen on top of a big Douglas fir tree that had fallen earlier. Prior to this big mess, the bay tree had been leaning on the Douglas fir tree. Now, it just continues to deteriorate. The precariously disfigured limb that remained last May was the most recent victim of gravity. Not much of the tree remains.

1. This was what we were concerned about. The disfigured and fractured trunk twisted from leverage exerted onto it by an upper limb, which is now extended downward instead of upward.P00718-1

2. Damage was impressively minimal. An exemplary specimen of Chinese maple sustained a direct hit from the main limb of the bay tree, but also sustained only minor structural damage.P00718-2

3. The trail somehow remained passable, although closed because of the big fallen limb dangling above. As the limb was dismantled, the fractured portion of the trunk broke away and fell.P00718-3

4. This big piece of the twisted and fractured portion of the trunk looks like a canoe, and is about as big. This was suspended more than twenty-five feet up, which is why the trail was closed.P00718-4

5. What remains of the bay tree is still severely disfigured, but is not so dangerously structurally compromised. It can remain until another arborist can get here to remove it and other trees.P00718-5

6. It looks worse up close. Nonetheless, there is not much we can do about it now. The limb to the far right originates from the same trunk. The big gray trunk in the background is a tan oak.P00718-6

Horridculture – Solar Power

P00715
This gives a new meaning to ‘shade tree’.

Leaves are the original solar panels. They collect solar energy, and convert into useful resources. Some of those resources get converted into other resources that are good for human consumption, such as fruit, vegetables, lumber, firewood and oxygen. However, one resource that leaves do not produce is electricity.

That is why the big solar array pictured above was installed over a big parking lot. There are a few of these arrays in this parking lot, and more in other nearby parking lots. Many trees were cut down to accommodate them. People who work nearby can use the electricity more than they could use vegetation, or anything that vegetation could produce within this area.

Shade trees are nice over parking lots, but are not necessary over a parking lot that is shaded so thoroughly by such big solar arrays. After parking during rainy weather, an umbrella is only necessary between the solar arrays and the adjacent office buildings. There are no more fallen leaves to clean up. Pavement and curbs will no longer be displaced by growing roots.

The red gum that is also pictured above, under the solar array, is not so impressed. It likely grew from a root of a red gum that was removed so that the solar array could be constructed. Sadly, it must be cut down again, not only because it is under the solar array, but also because it is against the sidewalk. It has clearance problems both above and below.

It is rather ironic that even after all the trees that formerly shaded this parking lot were cut down for the installation of this solar array, this young red gum that is so determined to survive can not stay. I can not help but wonder what this young red gum thinks of green energy.

Bad Date

P00712-1
No one likes a bad date.

Date orchards that were displaced by the expansion of urban sprawl around Las Vegas in the 1990s were the source of the many recycled mature date palms that briefly became popular for large scale landscapes at the time. Most of the trees within the orchards were female, with only a few male pollinators. (Pollinators can live remotely, where they provide pollen for dusting.)

Male trees were undesirable anyway, at least in conjunction with female trees. They are taller and lankier, with less pendulous foliage, so are less visually appealing. More importantly, they pollinate female flowers so that they make fruit. Of course, in orchards, fruit is very important. In landscapes, it is just a mess. Without male pollinators, female trees produce no messy fruit.

Consequently, most male trees were not recycled. Some were installed singly, or in exclusively male colonies, in landscapes that were reasonably isolated from female trees. After decades of dutiful service, this is how they were retired, . . . or not.

During the brief date palm fad, a colony of exclusively female date palms at a mall near here produced a minor crop of dates during its second year after installation. It was not a major mess, but it was perplexing. Eventually, someone realized that a single relatively small male date palm lived just outside of the landscaped areas. It likely grew there from seed as a curb mongrel.

Even though the male tree was too remote to pollinate the female trees sufficiently for a major mess, it was removed. It was not much bigger than the short and clumping date palm pictured above. This tree seems to be a curb mongrel as well, since it was not likely planted there purposely. Furthermore, it will also likely need to be removed. It is too close to the building behind.

Weeds?

P00711K-1
Although I can not be certain, I believe that this is prickly lettuce.

Pretty weeds do not get my attention like they do for others. They look too much like weeds to me. If I want to appreciate them, I must do so with intention. Sometimes, I do actually try. I did happen to notice these two weeds. However, now that I got their pictures, I have no use for either of them. Neither is readily useful for the gardening column. I will just share them here.

The yellow flower pictured above is most likely prickly lettuce. I really do not know. I know it as yellow chicory; but chicory does not bloom yellow. Some people think of it as dandelion, since the flowers are similar. These flowers stand much higher though, with only minimal foliage below. For the picture, I plucked this flower and stuck it in the ground to keep it still in the breeze.

The white flower pictured below is common bindweed. When I was a kid, I knew it as morning glory. In this close up picture, it looks like a fancier garden variety of morning glory, although the flower is much smaller. Real morning glory happens to look good in white, like this one does. If it is fragrant, I have never noticed. It tends to creep along the ground more than it climbs.

It sometimes seems silly to me that others so easily notice how pretty weeds such as these are, especially while there are so many more flowers that are prettier. Then, I realize what others must think of what I consider to be pretty. For example, the pollarded blue gum with aromatic blue foliage that I enjoy so much, is the same species that gives all eucalypti a bad reputation.

Besides, these flowers were the prettiest in the otherwise bare meadow where I found them.

Bindweed looks like miniature morning glory.

Six on Saturday: Closeups II

This is the more foliar counterpart to the closeups for my Six on Saturday from last week. Some are closer than others. Some would be more easily identifiable without captions than others. All are quite random. All these subjects are in the storage nursery; but only #1 and #5 will eventually find homes in the landscapes here. The others will likely go into one of my own gardens. I have no idea of what to do with #2.

1. Agave pedunculifera – provided the most abstract picture of the six. The name is only a guess. Someone else might have been able to identify it as something else if more of it were visible.P00711-1

2. Eucalyptus globulus ‘Compacta’ – compact blue gum – was my second choice for juvenile blue gum foliage. It was easier to reach because it is more . . . compact. The other blue gum is tall.P00711-2

3. Cinnamomum camphora – camphor – is light yellowish green most of the time, and then gets slightly blushed with new growth late in spring. This young tree started late in partial shade.P00711-3

4. Trachicarpus fortunei – windmill palm – provided the second most abstract picture of the six. It is more recognizable though. Mediterranean fan palm is darker. Other fan palms are light.P00711-4

5. Picea sitchensis – Sitka spruce – was brought from Smith River, on the coast just south of Oregon. It does not seem to mind being so far from home. The happy new growth is impressive.P00711-5

6. Juniperus virginiana – Eastern red cedar – is my favorite this week because I brought it from Oklahoma. Cedrus deodara – deodar cedar – is the real cedar that provided the background.P00711-6

Horridculture – Weed Whackers

P00708
This must be the better half.

This neatly sliced prickly pear is too silly to rant about. There is another just like it. Two others were not sliced, as if, after the first two, someone realized that there was more to the roadside meadow than combustible dry grass. The prickly pear were put out there just last winter. They each extended only a single pad half a foot or so above grade, so were obscured by the grass.

Realistically, the damage is minimal and tolerable here. The priority of the crew who performed the vegetation management was to cut down all the combustibles. They did an efficient job of it. They did not expect to encounter anything that had been intentionally installed out there, or even any desirable vegetation. Besides, this prickly pear will recover as if nothing happened.

Unfortunately, damage caused by weed whackers is rarely so innocuous. Weed whackers are one of the most commonly misused horticultural power tools, and are very often used by those who are not aware of how to use them properly. They are easy enough to operate that minimal consideration is given to the potential for damage that they can cause. It is a bad combination.

Because weed whackers are often and improperly used to cut tall grass that is too close to trees for lawn mowers to cut, they commonly strip off bark and cambium from young tree trunks. A tree can not survive without its cambium, and quickly dies if too much is stripped away from the base of its trunk. That is why it is very important to pull weeds from around trees instead.

For now, there is nothing to do for the two sliced prickly pear. The bud to the upper right corner of the pictured specimen is beginning to develop into a new pad.
