Canna Virus

This is not a new problem, but it is infuriating nonetheless. ‘Cleopatra’ canna expressed symptoms of at least one virus about two years ago. A few other nearby cannas expressed similar symptoms shortly afterward. ‘Australia’ canna is particularly expressive of foliar streaking caused by virus. Isolation and disposal of obviously infected specimens seems to have prevented dispersion of the virus or viruses; but I really am uncertain. Three cultivars of Canna musifolia have suspiciously avoided any infection from adjacent infected cultivars. I can not help but wonder if they are actually infected but merely asymptomatic, and possibly able to transmit viruses to cultivars that are more expressive of symptoms. The canna in this picture is an important cultivar because it is one of only two remaining original cultivars that could have inhabited the landscapes here since about 1968. Because of gophers, very little of it remain, and some of what remains succumbed to virus already. I am quite protective of these few specimens that have not been infected, but would also like them to be able to inhabit the landscapes with the questionable Canna musifolia cultivars. For now, I must wait until they proliferate enough for some to be expendable.

Six on Saturday: Leave It To Beaver

Squirrels have been chewing some of our foliar plants since spring. Now that they found our banana trees, I am more concerned. Their damage is more severe and impossible to ignore.

1. Musa acuminata ‘Golden Rhino Horn’ banana got chomped by a squirrel, right where its new leaf is unfurling. A Musa acuminata ‘Ever Red’ banana got chomped at its base! Squirrels are also chomping other cultivars of banana and two species of Chamaedorea.

2. Musa ingens, oem, or giant highland banana demonstrates what a young banana tree should look like without squirrels chomping on them like little arboreal demon beavers. I will be furious if I see any more damage on any of these more prominent banana trees.

3. Crassula ovata, jade plant is not often considered to be a ‘foliar’ plant, but happens to function splendidly as such by obscuring the otherwise bare bases of several of the small banana trees. It all grew from pruning scraps from one big, old and sculptural specimen.

4. Hedychium coronarium ‘Vanilla Ice’ ginger was chomped by squirrels as soon as new growth began to develop last spring. Fortunately, it recovered. Although it appears to be ‘Vanilla Ice’, and likely is, I was told that its flowers are white rather than vanilla yellow.

5. Alocasia gigantea, elephant ear was also chomped by squirrels as soon as it started to regenerate foliage last spring, and also recovered. It is quite large now. If its foliage were not so simple, it would be as striking as that of the old fashioned Philodendron selloum.

6. Philodendron selloum ‘Lickety Split’ philodendron produces the striking foliage of the species, but not the form. Its multiple trunks are so stout that I have not seen them yet. I suspect that individual leaves do not get very big either. Squirrels have ignored it so far.

Fountain

Life was very different where I lived in town in the 1990s. I miss that neighborhood and my garden there very much. However, it was an urban neighborhood, only a few blocks from the interchange of Highway 17 and Highway 85. My neighbors had me build a small solar powered fountain adjacent to a patio of our apartment building to obscure the ambient urban noise. I thought it was a silly component of the landscape, but everyone else was fond of it. Well, sadly, I left that home and garden many years ago, and relocated to a quieter neighborhood a few miles away. Except for a few lights at night on distant hillsides, I can see no other households. I do not hear much more from them than I can see. Air traffic to and from Mineta is the most traffic that I notice, if I notice. In fact, the noisiest noise in my garden is from this creek that flows through it. I flows all day at night, so does not stop when the sun goes down. I can not unplug it. It gets louder during winter. Perhaps I should build another solar powered fountain to obscure the noise.

Six on Saturday: Construction Site

An old deck at work is presently being replaced. Potted cannas that resided on it needed to be moved. Camellias below it are in the way, but safe for now. It is quite a big project.

1. Camellia japonica, camellia under the old deck are temporarily getting more sunlight than they are accustomed to. There are about eight. This will not last long, though, until the new deck replaces the old. The disheveled irrigation tubing was for pots on the deck.

2. Camellia japonica, camellia at the far end of this row is somehow undamaged by this accumulation of debris from the dismantled deck above. I am impressed. Some extent of damage is expected from such a project, particularly with so many camellias in the way.

3. Canna indica, canna was looking good on the deck across the road in the background. Not only were they removed, but because of a realistic concern that they promote decay, they will not return to the new deck. For now, they were straightened into position here.

4. Canna indica ‘Australia’ canna is probably the boldest of the five even without bloom. The others are ‘Wyoming’, ‘Cleopatra’, ‘Stuttgart’ with an unidentified cultivar with large red bloom, and ‘Inferno’ with a notably tall but unidentified cultivar of Canna musifolia.

5. Phoenix roebelenii, pygmy date palm paired on another area of the deck will also need to be removed prior to a second phase of reconstruction. Unfortunately, I do not know if these big old pots can be moved intact. Both are deteriorated, fractured, and very heavy.

6. Pelargonium X hortorum, zonal geranium should also be removed, but from another situation. They were originally installed to hold posts for the signs that are now attached to the fence behind them. Now they just get bashed by parking cars. One is already gone.

Which Mesquite?

Is this velvet mesquite, Prosopis velutina, or honey mesquite, Prosopis glandulosa? It is still too young to identify. I suspect that it is velvet mesquite because I found its seed in a landscape in Surprise, Arizona, and velvet mesquite is the most common species within landscapes there. Also, the foliage of the trees that provided the seed resembled that of velvet mesquite more than that of honey mesquite, with relatively smaller leaflets. The bark was medium brown, so was not quite as dark brown as I would expect for velvet mesquite, but more brown than tan, as I would expect for honey mesquite. This little seedling may not look like much now, but it is the only survivor of the many seed that I collected. Only a few germinated, and slugs ate them before they extended their first leave beyond their cotyledons. This seedling germinated last, and was promptly canned in a four inch pot that I brought inside at night for protection. I hope that, before the end of summer, it grows large enough to survive winter. It should. Regardless of its identity, I hope to eventually use its stems for smoking and, if it grows large enough, barbecuing.

Six on Saturday: Pestilence

Molluscs, rodents, insects, virus, fungal pathogens and an identified disease that causes gummosis; we have it all. I know that it is nothing to brag about, but it makes a good six.

1. Tamarindus indica, tamarind seedlings are popular with slugs. Not much else here is. Weirdly, slugs do not seem to consume the foliage. They only coat it with slime that does not rinse off. The foliage eventually deteriorates. What is the point of this odd behavior?

2. Prunus armeniaca, apricot trees sometimes exude gummosis as a symptom of disease or boring insect infestation. I can not see what caused this, and do not care to. I will just prune it out. I know that it will not be the last time. Gummosis is common with apricots.

3. Chamaedorea plumosa, baby queen palm was chewed so badly by some sort of rodent that it will not likely survive. I suspect that a squirrel did this. I have not seen any rats or their damage since Heather arrived. This is one of only two rare baby queen palms here.

4. Ensete ventricosum ‘Maurelii’ red Abyssinian banana was initially infested with aphid and associated mold. The aphid disappeared, as it typically does, but the mold remained and ruined the currently emerging leaf. I hope that the primary bud within does not rot.

5. Passiflora racemosa, red passion flower vine has been defoliated a few times just this year by a few of these unidentified caterpillars. The caterpillars leave after they consume all foliage, but then return shortly after the foliage regenerates, while I am not watching.

6. Canna indica ‘Australia’ canna is infected with canna mosaic virus. Several others are also, although they do not express symptoms as colorfully as ‘Australia’ does. Most other cannas are isolated from this virus within their landscapes. I am infuriated nonetheless.

Archaeology

Working within landscapes is obviously very different from working on the farm. Actually, there are too many differences to mention. One difference is people. There are only a few on the farm, spread out over many acres. Conversely, the landscapes that I work in are designed for use and enjoyment by countless people who attend events there. I can rarely get away from all of them. Although it can be fun, it can also be challenging, and often interesting. On rare occasion, I find artifacts that make me wonder about whomever left them. This tiny terracotta pot with “Zoey” painted on it, for example, was found in a small landscape outside of a bookstore, quite a distance from the facility a which young children typically engage in such crafts. I hate to think that Zoey misplaced it there. I sort of hope that it was intentionally left there, perhaps containing a tiny plant that Zoey hoped a gardener would find and add to the landscapes. If so, I found it too late and empty. Zoey does not need to know that. Hopefully, if she returns, she finds something that she believes to be her plant growing happily in our landscapes.
