Six on Saturday: Attempted Autumn

Astronomical autumn began more than a month ago. It is about a third done, with about two thirds remaining. Meteorological autumn can start at any time. Sometimes, it starts, but then pauses before restarting a bit later. Sometimes, the first rain is the beginning of the rainy season, which typically continues through winter. A bit of rain arrived between Wednesday and Thursday, and a bit more is here now, but no more is in the forecast for next week. Regardless of future weather, some flowers bloom, or at least try to, as late as they possibly can. Of course, some actually prefer to bloom even later and during winter. Apologies for the lack of focus of pictures #4 and #6.

1. A ‘chance or rain’ in the weather forecast here is generally not taken too seriously until something like this happens. It is a genuine puddle. It is wet, and full of water from rain.

2. Sequoia sempervirens, coastal redwood seems to enjoy this damp weather. It actually enjoys all weather, but appears to be more refreshed by any interruption of arid warmth.

3. Lemna minor, duckweed is even weirder with this border of white foam that develops as the first rain washes away pollen and dusty crud that accumulated since the last rain.

4. Hedychium coccineum X coronarium ‘Peach Delight’ ginger lily, which was blooming for last Saturday, is trying to bloom again. I already doubted its ability to follow through.

5. Brugmansia X cubensis ‘Charles Grimaldi’ angel’s trumpet looks like Carl’s Junior ate too much of its own food. I added this because of response to angel’s trumpet last week.

6. More interestingly, it produced this seed pod. Such hybrids should be sterile. I can not help but wonder if seed is true to type. If so, propagation by cuttings is easier than seed.

Horridculture – Rocky XXIV . . . or XXV . . . or XXVI . . . Oh, I can not count them all.

another sequel

Winters are not very cold here. Otherwise, I might have assembled a fur coat. Instead, relocation of furs has been more practical than utilization. Besides, without exception, all were already in use when I encountered them. Actually, they were not relocated merely because I had no practical use for them, but, more importantly, because relocation was significantly less inconvenient to those who were wearing them at the time. Of course, it was not totally convenient either. That was sort of the objective. The inconvenience of relocation is a deterrent to those who wear the furs, who identify as racoons. They are unwelcome here. I realize that they eat mollusks and rodents; but neither mollusks nor rodents are problems here. I do not grow much vegetation that mollusks find to be appealing. Heather the kitty who identifies as a feline person is too proficient at deterrence of rodents to have use for any assistance. Actually, Heather is one of the two primary reasons that it is necessary to relocate raccoons. Rhody is the other. Unfortunately, raccoons have potential to become impolite or even dangerously hostile with my canine and feline housemates. Relocation does not permanently eliminate them, but it annoys them enough that, by the time they return, they are much more careful about avoiding us and our space. Also, their impressionable associates seem to learn from their examples. Because they can not be relocated off of the property, they go less than a mile away. So far, that seems to be sufficient. I do not know how long it takes for them to return, but I suspect that it takes quite a while. After this most recent relocation, I do not expect another relocation to become necessary until members of the most recent generation mature enough to become a problem.

Off Color – Very Variable Variegation

‘Stuttgart’ canna

Reversion among vegetation is the loss of an aberrative genetic characteristic, such as variegation or bronze foliar color. Because most genetic aberrations that are susceptible to reversion are disadvantages, reverted growth generally performs more efficiently, and displaces remaining genetic aberrative growth. For example, because its variegated portions lack chlorophyll, variegated foliage is less vigorous than foliage that is not variegated. Therefore, if not removed, unvariegated reverted foliage is likely to grow faster and replace variegated foliage. This ‘Stuttgart’ canna leaf seems to have done the opposite of reversion, by exhibiting such extreme variegation that all green color is lacking. Fortunately, it is not as bad as it looks. This is merely very variable variegation. Just as a few leaves may be completely green without actually reverting permanently, a few leaves are extremely variegated, and on rare occasion, a few, such as this leaf, may lack any obvious green color. Leaves that developed after and above this leaf exhibited more typical variegation with both green and white. Otherwise, this particular cane would not survive for long without chlorophyll for photosynthesis. The flowers are unaffected because they derive their floral color from pigment rather than chlorophyll. White redwood foliage can survive without chlorophyll only because it can rely on resources provided by the normal growth with green foliage that it is attached to, almost parasitically. Such growth is considered to be albino, but because it merely lacks chlorophyll rather than pigment, it is technically not albino. Furthermore, it is technically not variegated, since it is so completely white, without any green chlorophyll. Oh, this is more complicated than it should be. It is probably better to simply appreciate appealing genetic aberrations such as white, variegated or other colorful foliage. ‘Stuttgart’ canna will not refresh its variegated foliage until the end of winter.

Messy Mast

This is the mess that remains after acorns get raked or blown off pavement.

Masting is a technique that oaks and many other genera use to both outsmart and exploit squirrels and other wildlife that both consumes and disperses their seed. For several years, oaks here produce enough acorns to sustain a population of squirrels that is limited by their production of acorns. It may not seem to be very effective, since the squirrels consume almost all of the acorns, leaving very few or none to grow into new trees. Then, every several years, the same oaks collectively produce a ‘mast’, which is a crop of acorns that is too excessive for the limited population of squirrels to consume as thoroughly as they typically do. Squirrels instinctually bury many of the surplus acorns anyway. Because they do not return to dig and eat all of their buried acorns, some acorns grow as new trees. This is how the oaks sustain those who disperse their seed, but also get them to disperse their seed without eating all of it. Mast crops of acorns supposedly typically precede exceptionally rainy winters. So far, the mast this year is only coinciding with a messy situation with drippy nut disease. It is caused by bacterial infection of wounds that are caused by filbert weevils, filbert worms or other insects that damage developing acorns. Consequently, squirrels are ignoring many of the unusually abundant but damaged acorns, leaving icky messes of infected acorns and the goo that they exude. When it eventually arrives, the first rain will make this mess even messier. Later rain should rinse some of it away. It is impossible to know how successful this mast will be, since it is impossible to know how many viable acorns will actually contribute to the abundance and grow later, and how many will merely contribute to this unusually messy mast.

Six on Saturday: Firsts & Lasts

Angel’s trumpet should be finishing bloom by now. Instead, and even while their foliage is fading with cooler weather, their bloom continues. Only the unidentified cultivar with single pink flowers currently lacks open flowers, but even it is budded for potential later bloom. (I neglected to get a picture of a flower of ‘Charles Grimaldi’ angel’s trumpet only because two pictures of angel’s trumpet is sufficient.) While angel’s trumpet is finishing, Algerian iris and ‘Peach Delight’ ginger lily are blooming for their first time here and red butterfly ginger is generating bulbils for its first time here. I was not aware that this sort of ginger generates bulbils. Otherwise, I could have allowed the other gingers do so also.

1. Hedychium greenii, red butterfly ginger is making bulbils! I did not know that it knew how to do so. I am now glad that I refrained from pruning the bloomed canes out earlier.

2. Hedychium coccineum X cornonarium ‘Peach Delight’ ginger lily started to bloom so late that I did not expect for it to actually show this much color and confirm its identity.

3. Iris unguicularis, Algerian iris is also blooming for the first time here, since its arrival from Tangly Cottage Gardening. It should bloom more for winter. Is it blue or purplish?

4. Brugmansia, angel’s trumpet of an unidentified cultivar, species or perhaps hybrid, is trying to bloom with its last big single pink flowers of the season, and it just might do so.

5. Brugmansia insignis ‘Single White’ angel’s trumpet is my favorite in regard to bloom, but not one that I recommend. It is blooming nicely though, now that its season is done.

6. Brugmansia candida ‘Double White’ angel’s trumpet also intends to bloom until it no longer can. It bloomed only sporadically since spring, but better than the ‘Single White’.

Horridculture – Pave Paradise

pavement within pavement within pavement

The Santa Clara Valley really is, as it was formerly known, the Valley of Heart’s Delight. A long time ago, it was famous for vast orchards that thrived in its exemplary climate and soil. The climate is still here, but so are nearly two million people who now live where orchards formerly were. Not so much of the formerly productive soil remains exposed, and almost none is appreciated for its potential. Urban development continues to expand to occupy more of it. At a strip mall in the Berryessa District of San Jose, I noticed what appeared to be gravesites of small patches of once exposed soil that died slow deaths after all other soil around them was developed. The concrete pavement outside of and below the yellow curbs was likely the original parking area, walkway and paved patio, which were separated from each other by what was likely small landscaped patches of exposed soil within and at the same level as the yellow curbs. Sometime after the area outside of the curbs were paved, most of what was likely exposed soil within was also paved with exposed aggregate concrete, leaving only what was likely three smaller square patches of exposed soil, perhaps for trees to survive in. Eventually, even these three smaller square patches of exposed soil were also paved with simpler concrete. It is impossible to say why all this concrete pavement was necessary, or why exposed soil was so objectionable. Perhaps the dirt was dirty. Perhaps it was infested with weeds. Perhaps all this concrete is some sort of Brutalistic art. Regardless, the good soil below is now useless. The patio now lacks shade from trees. A little bit more of the Santa Clara Valley can not sustain any vegetation. A little bit more of Paradise is paved.

Brutalism?

Off Color – Reversion

‘Siam Ruby’ banana started to display bronze foliar color before it seemed to revert to chartreuse.

Of the two dozen or so cultivars of banana here, ‘Siam Ruby’ is one of only two that are merely ornamental. It and ‘Zebrina’ produce fruit that is too seedy to be reasonably palatable. Both are instead grown more for their colorful foliage. ‘Siam Ruby’ develops bronze foliage with yellowish green spots. ‘Zebrina’ develops darker bronze or brown color mixed with more but darker green. Since their distinct foliar colors are their primary attributes, I was initially disappointed when ‘Siam Ruby’ seemed to revert to chartreuse green without any bronze foliar color. I was informed that it is typically chartreuse while very young or if shaded, but develops bronze foliar color as it matures with adequate sun exposure. However, I still suspect reversion because it started to display broad bands of bronze foliar color earlier, but became exclusively chartreuse green afterward. While inquiring about the potential for reversion with this particular cultivar, I learned that ‘Margarita’ originated as a reverted sport of ‘Siam Ruby’ with exclusively bright chartreuse foliage, just like the specimen of ‘Siam Ruby’ here that I suspect reverted. So, I may have indirectly acquired a fake copy of ‘Margarita’, which should contrast splendidly with the bronze foliage of both ‘Siam Ruby’ and ‘Zebrina’! The grower who sent the original pup of ‘Siam Ruby’ already sent a replacement. Now I want to see what the original pup does. If it recovers its bronze foliar color, there will be two copies of ‘Siam Ruby’ here. If it does not, I will consider it to be ‘Margarita’, which is still a rare cultivar. In a way, I sort of hope that it does not recover. A glitch such as this is a good excuse to try something that I would not try otherwise. Actually, we already have plans for it.

New foliage of ‘Siam Ruby’ banana is exclusively chartreuse green, without any bronze.

Off Color

Borage can bloom pink, although it should fade to blue.

Borago officinalis, borage blooms almost exclusively with blue flowers. Those that bloom with white flowers are a naturally rare variant, although a slightly less than natural white blooming variety is available. Although white is my favorite color, I wanted to grow the more common sort that blooms with blue flowers merely because, to me, blue seems like the more natural color for the species. Besides, white borage flowers look rather bland. Actually, I am not much more impressed with blue borage flowers, but wanted to grow borage just to see what all the fuss was about. Though they were not expected to be viable, I was pleased that someone shared some expired seed with me. Because I expected none of them to grow, and expected that even less than none would grow if I delayed sowing them until after winter, I tossed the seed into the cans of other plants in the recovery nursery. I figured that if one or a few grew, I could pull them up and can them separately. Only a few days later, they all seemed to be germinated and growing! I extracted and plugged them into one more six-pack than a full flat of cells, which is forty-two seedlings! The problem is that summer is over, and borage does not overwinter well, even here. I am pleased with them nonetheless, and am confident that some can survive with shelter. I figured that with so many seedlings, that one or more might possibly bloom with white flowers. I noticed floral buds a while ago, so was watching for my first borage bloom. I was not expecting this! What is weirder is that all are blooming like this. Apparently, it is normal for borage to bloom with pink flowers that fade to blue during autumn.

Six on Saturday: Red Flag Warning

A Red Flag Warning that began Thursday night continues at least until five this evening. Arid wind severely increases the risk of wildfire during this time. The strong wind can be hazardous, even without fire. Big trees become big problems.

1. Wind developed soon after sunrise yesterday. I tried to get a picture of foliar debris as it fell from the forest canopy, but took only this. Sequoia sempervirens, coastal redwood makes the background, with Quercus agrifolia, coast live oak in the lower left quadrant.

2. Turkeys should hide from such wind. This one was alone and in a hurry, likely to find a sheltered situation with others, and just as likely, after shredding the red berries of the firethorn, Pyracantha coccinea. I saw no others as the wind continued through the day.

3. Sequoia sempervirens, coastal redwood is remarkably stable but structurally deficient where exposed to wind, which is why it grows in dense and mutually sheltering colonies. These big fractured limbs are very heavy, and fell with deadly velocity from very high up.

4. Umbellularia californica, California bay is often destabilized by structural deficiency. In other words, although its trunks and limbs are generally not structurally deficient, rot often compromises the structural integrity of the roots, which then become destabilized.

5. Two California bay trunks that destabilized and blocked the road in the picture above are obscured on the ground by their own foliage here. The fractured trunk that is visible was not structurally deficient, but was pulled down by the other two as they destabilized.

6. Hedychium coccineum X coronarium ‘Peach Delight’ ginger is likely too late to finish blooming. I would like to see it bloom to confirm its identity, but may need to wait until next year. Although irrelevant to the wind, I thought I should feature at least one bloom.

Horridculture – Pilferage

Cuttings could have been taken more neatly than this.

Aeonium arboreum, tree houseleek and a few other succulents within my tiny downtown garden are very important to me. They are from the former garden of a friend who passed away years ago. They have performed very well for this particular application since their arrival. They are resilient and undemanding, and provide delightful foliar color and form. The darkest bronze cultivar of tree houseleek that I ever grew arrived with them, but over a few months, was stolen until none of it remained. As the first few cuttings grew enough to become prominent, they were either taken completely, or deprived of their upper foliar rosettes. Any remaining rooted but bare stems eventually succumbed as any subsequent foliar rosettes that they generated were also taken. The surviving succulents remain only because they are both less popular, and too numerous for complete depletion. Actually, I would not mind if those who find these succulents to be appealing sometimes take a few pieces. I merely find their lack of tact to be annoying. I expect them to know better than to take the last of something. Also, I expect that they should have enough sense to take bits from where they would not be missed, and to do so neatly, without leaving broken stubs. Quite a few stems are sometimes overgrown or extending awkwardly outside the planter box, so should be removed anyway. Many stems that are overwhelmed by upper growth could be removed without compromising collective visual appeal. That might actually be a common occurrence that I am not aware of because it is done properly. Stems of these succulents can be easily broken neatly at their unions, without leaving stubs, so pruning shears are not even necessary. Fortunately, these damaged tree houseleeks will recover like they and other succulents always do.
