Six on Saturday: Flowery Bits III

Merry Christmas! Okay, perhaps not. This posted at midnight, precisely as Christmas Day ended. These are not exactly Christmas flowers anyway. They are not even Christmas colors. The pictures are actually from the previous week. I knew then that I would not likely want to go out to get pictures last week. Until now, Christmas was the priority. There was no work to go to.

My six are very limited this week. There are only two genera and three species. There could be more if the Osteospermum have species designations. I know them only as ‘hybrids’. If there are any cultivar names, I do not know what any of them are.

1. Lantana montevidensis – grows as a ground cover. The color range of the bloom is limited. This color is common, but I thought that individual flowers more commonly have white centers.

2. Lantana camara – is the ‘other’ lantana. It is shrubbier and better foliated. Floral color is more variable and generally more brightly colored. Bloom is not as extensive, but is more prolific.

3. Lantana camara – likes this particular landscape where I got these pictures. Another solitary specimen down the road and at a lower elevation already looks shabby from cooling weather.

4. Osteospermum – within this landscape are all modern hybrids. If anyone knows who their parents are, they do not share such information anymore. I think this color might be ‘lavender’.

5. Osteospermum – looks more purplish than the previous picture. I am no good with colors. Despite the attributes of modern hybrids, I still prefer old fashioned Osteospermum fruticosum.

6. Osteospermum – colors are not easy to describe. Is this one light burgundy red or ruddy pink? There might be six or so cultivars here. This unidentifiable color happens to be my favorite.

Scotch Moss

Sctoch moss resembles Irish moss, but is lighter yellowish green rather than dark green.

Too much water can be as much of a problem as not enough. Too much direct sun exposure can likewise be as much of a problem as not enough sunlight. Scotch moss, Sagina subulata ‘Aurea’, wants regular but not excessive watering, and only a bit of shade without darkness. To propagate, pieces with roots can be torn from healthy plants and ‘plugged’ (planted) as new plants where more are desired in early spring or autumn.

The remarkably finely textured and dense foliage makes a nicely refined ground cover for confined spots, or fills in the spaces between stones in a wall or walkway. It gets only about an inch deep, with tiny and obscured stems that get no longer than four inches. Stems develop roots where they touch the ground to creep any farther. The tiny and narrow leaves do not get much longer than a quarter inch. Tiny white flowers that bloom late in spring may not get noticed. What distinguishes Scotch moss from richly deep green Irish moss is that it is instead yellow or almost chartreuse.

Prune Fruit Trees While Dormant

Dormant fruit trees should be pruned aggressively.

After centuries of breeding for abundant production of unnaturally large fruit, deciduous fruit trees have become dependent on specialized pruning while they are dormant through winter. Without pruning, most eventually become overgrown and overwhelmed by their own fruit. The weight of excessive fruit disfigures and breaks limbs. Pathogens proliferate within distressed foliage, crowded fruit and surplus fruit that falls to the ground.

Pruning not only improves the structural integrity of the limbs, but also limits the production and weight of the fruit that will be produced. Limiting production concentrates resources, so that there are fewer, but considerably better fruits, instead of too many inferior fruits. Concentrating the growth of the fewer new stems that develop in spring promotes vigorous growth that is more resistant to pathogens. Ideally, pruning also limits the height of fruit trees, so that much of the fruit develops closer to the ground.

Peaches, nectarines, apricots, plums, prunes, and cherries are all relates ‘stone’ fruits (of the genus Prunus), so require various degrees of similar pruning. Peach trees produce the heaviest fruit, so need the most aggressive pruning. Cherries trees produce significantly lighter and smaller fruit, so get pruned relatively minimally. Almonds (which are actually the ‘pits’ of a similar type of stone fruit) get shaken from their trees, so there is no advantage to keeping production close to the ground.

The ‘four Ds,’ which are ‘Dead, Dying, Diseased and Damaged’ stems should be pruned out first. Then the vigorous stems that grew last year should be thinned and cut back, but not removed completely. They are the stems that will bloom and develop fruit the following year. Pomme fruits, such as apples, pears and quinces, develop on similar newer stems that should likewise be pruned down, but many also develop on lower ‘spur’ stems that elongate so slowly that many spurs may never need to be pruned.

Most young deciduous fruit trees will need more pruning each year as they grow. Fortunately, pruning becomes more familiar with experience. Because pruning fruit trees is so specialized and important, it is worth studying more thoroughly.

Leaves Leave

For this Wednesday, I will not even try to comply with the ‘Horridculture’ meme. As I reblog old articles, I take what I can get. I could complain about the subdued autumn foliar color here, but I happen to appreciate our mild climate that does not get cool enough for better color.

P80104+I do not know where they went. There are plenty that are not worth getting pictures of, but the pretty and colorful ones that I wanted to show off in the ‘Six on Saturday’ post are gone. I suppose that they are still out there. They just are not as pretty and colorful as they were earlier.

Pistache leaves deteriorate quickly. They were very colorful while still in the trees, but were not much to look at by the time they were on the ground.

Ginkgo colored well too, but after I got that one picture of the single leaf, I could find no others. The tree that sent that leaf is not in the neighborhood. ( https://tonytomeo.wordpress.com/?s=birthday )

I suppose that I could have gotten a good picture of a colorful sweetgum leaf. I just did not bother with them. Nor did I bother with flowering pear.

Flowering Dogwood

Bloom like this waits for spring.

Flowering dogwood, Cornus florida has something in common with Poinsettia. The most colorful component of their bloom is not floral, but is instead foliar. What appears to be petals are colorful leaves known as bracts. Exactly four bracts surround each small cluster of tiny and unimpressive pale green real flowers. These bracts are most popularly white, but can be pink or rarely brick red.

The deciduous trees are bare now, but bloom spectacularly in early spring. Any necessary pruning should happen after bloom, and preferable after new foliage matures somewhat. Floral buds for next year are already prominent on the tips of bare twigs. Dormant pruning would eliminate some of the buds prior to bloom. For now, only minor grooming of unbudded interior growth is practical.

Mature flowering dogwood trees can be twenty feet tall, but typically stay lower. As understory trees, they prefer a bit of shelter from larger trees. Foliage can scorch if too exposed. Some cultivars have variegated foliage. All can develop vibrant orange and red foliar color for autumn, even with minimal chill. Floral debris resembles fallen leaves that fall just as new and real foliage develops.

Winter Is Time For Pruning

Pomegranate trees appreciate major specialized pruning.

Plants are unable to migrate to warmer climates for winter like so many migratory birds do. They are immobile for their entire lives. Only potted plants can move to more sheltered situations when the weather gets too cool for them. Some get to live inside as houseplants. Otherwise, they all must contend with seasonally changing weather. Most are impressively efficient with how they do so.

Most that do not adapt efficiently to cool winter weather are tropical species. Tropicals that are native to high elevations can tolerate cold weather. However, many of the familiar tropical species are from low elevations where they never experience cold weather. Frost damages or kills them. Warm season annuals do not tolerate cool weather either. They just die at the end of their season.

Otherwise, almost all other plants go dormant through winter, at least to some degree. Even evergreen plants, which may not seem to go dormant, grow much slower during winter, or do not grow at all. Deciduous plants are much more obvious about their dormancy, because they defoliate. While bare, they are less susceptible to damage from wintry weather. Dormancy is like hibernation.

This is why winter is the best time for pruning most plants. While dormant, they are less susceptible to distress associated with pruning. Some plants expect some degree of damage from wintery weather during their dormancy anyway. They wake in spring, with no idea of what happened while they slept, and resume normal growth. Winter pruning conforms quite naturally to their life cycles.

There are, of course, a few exceptions. Citrus and avocado should not be pruned during winter. Such pruning stimulates new growth, which is sensitive to frost. Maple and birch should have been pruned earlier. They bleed annoyingly if pruned late into winter. Flowering trees that produce no fruit, such as flowering dogwood and flowering cherry, should be pruned after bloom, late in spring.

Deciduous fruiting trees, such as apricot, cherry, plum, peach, apple and pear, require specialized pruning during winter.

Santa Ana Winds

Santa Ana Winds are confined to Southern California. Although this region sometimes experiences similar offshore winds, such winds are neither as warm nor as arid as those that come from the Mojave Desert. This article is three years old, so the fires mentioned are old news.

tonytomeo's avatarTony Tomeo

P71221+They have been a part of life in Southern California longer than anyone can remember. The Santa Ana Winds have been blowing down from the high deserts to coastal plains long before people arrived in the region. They are arid and usually warm before they leave the Great Basin and Mojave Desert, and they get even warmer as the flow downhill through mountain passes. That is what makes them so dangerous during fire season. Wind alone accelerates wildfire. Warming arid wind desiccates fuel, making it more combustible before wildfire arrives.

Santa Ana Winds are so regular that they affect how tall trees grow within the regions of the mountain passes where Santa Ana Winds move the fastest. Tall Mexican fan palms that grew up straight where sheltered from wind near the ground innately lean with the prevailing wind as they grow up and become more exposed. Those closer to the…

Dead Box Elder Update

After three years, this remains as undiagnosed as the mysterious death of the mistletoe that was described two weeks ago.

tonytomeo's avatarTony Tomeo

P71223P71223+What is killing the box elders? (https://tonytomeo.wordpress.com/2017/10/04/what-is-killing-the-box-elders/) I still do not know. I know that does not sound like much of an update. All I can share is some pictures of secondary symptoms observed now that the affected trees are deteriorating.

The two pictures above, although not relevant to any symptoms, are important to our Community because the historic Felton Covered Bridge just got a new roof! (https://tonytomeo.wordpress.com/2017/12/02/felton-covered-bridge/) Dead box elders that are already starting to destabilize and collapse are now leaning onto the edge of the new shingles! They really need to be removed before winter storms move them around, and they dislodge any shingles.

The first of the two pictures below show basidiocarps associated with fungal decay of the trunks and roots. This decay destabilized and compromised the structural integrity of the necrotic trees with remarkably efficiency. The trees died only last spring, and…

Six on Saturday: Flowery Bits II

Rhody did not make the cut this week. There are too many minor flowers blooming. Only six can be shared here. Besides, flowers are more cooperative with getting their pictures taken than Rhody is. I should get six more flower pictures for next week as well, since I am trying to avoid the sort of dreary pictures I had been sharing, and the weather has not yet gotten interesting.

The botanical names of some of these flowers have changed over the years. The names I use may be outdated or updated. I can not be sure anymore. I am not certain about the identity of the hebe.

1. Hebe buxifolia, perhaps ‘Patty’s Purple’ hebe, is now beginning to succumb to cool winter weather. I am not certain if it has a definite bloom season. It seems to bloom randomly until frost.

2. Lobularia maritima, alyssum, is a warm season annual that finishes in winter, but replaces itself with seedlings that perform as cool season annuals for winter until warmer spring weather.

3. Diosma pulchrum, pink breath of Heaven, also seems to bloom whenever it wants to, although not quite as colorfully as hebe. This cultivar has lime green foliage instead of yellowish green.

4. Morea bicolor, butterfly iris, could be dug, divided, and shared with other landscapes. However, we can not adequately maintain the mature colonies that are already out in the landscapes.

5. Salvia greggii, autumn sage, is not just for autumn. Like the others, it blooms whenever it wants to. I like this one because it is only red. The flowers are too small to be both red and white.

6. Senecio X hybrida, cineraria, is leftover from when a few bedding plants were still added seasonally to a few prominent parts of the landscape. This one happens to be potted on a pedestal.

Leopard Plant

Leopard plant looks like it would be at home in the garden of Kermit the Frog.

The differences between false ligularia (Farfugium spp.) and real ligularia (Ligularia spp.) are so vague that the the names are commonly interchangeable. Leopard plant happens to be a real Ligularia japonica. The round and very glossy leaves are dark green with random spots of sunny yellow. Mature plants form rather dense foliar mounds about a foot wide and nearly as high. Prominent floral trusses that bloom in late summer or early autumn are a pleasant surprise, even though the small and sometimes feeble daisy flowers are typically only dingy gold, and often have brownish centers. Both ligularia and false ligularia are understory plants that naturally prefer the shelter of larger plants, so they prefer partial shade. They also like relatively rich soil and regular watering, although once established, they can recover efficiently if they happen to briefly get dry enough to wilt.
