Six on Saturday: Late Summer Flowers

Spring is the favorite season among the majority of those who enjoy gardening. I do not really have a favorite season though. Dormant pruning is perhaps my favorite chore, which happens in winter. Stone fruits, which are perhaps my favorite, ripen in summer. I so enjoy the foliar color of autumn. Well, it is still too early for autumn foliar color. In the meantime, the flowers of late summer are blooming. Compositae is the ruling family for a while. It is not too late for the last few roses. Japanese anemones, although locally rare, bloom also.

1. Sunflower should be the grand finale; but I could not get a sufficiently good picture, without the utility cables above and the sun in the background. Nonetheless, it exemplifies late summer.

2. Rose is the one flower of these six that has been blooming all summer, so is not actually limited to late summer. It is a cheap carpet rose, which I loathe, but happens to provide pretty color.

3. Chrysanthemum landed in the landscapes after getting left behind from an event. It was formerly a fancy ‘potted mum’. Now, it is unrefined and rustic, but blooms reliably for late summer.

4. Marigold is one of many annual bedding plants that I can not figure out. Is it a warm season annual that really could bloom all summer, or is it actually limited to late summer and autumn?

5. Marigold exhibits a limited color range of yellow, orange, rusty red, almost brown and very pale yellow that is described as white. We got only yellow, as seen above, and this simple orange.

6. Anemone, or more specifically, Japanese anemone, is a rather mundane pale pink. I would prefer it to be either clear white or a more blatant pink. I like it though, because it is what we got.

Naked lady

These naked ladies are not shy.

While so many flowers are finishing their bloom and leaving their drying foliage behind, naked lady, Amaryllis belladonna, is just beginning to bloom, naked of any foliage. Clusters of a few to several bright pink flowers stand on bare stems about two feet tall. Individual flowers are about two and a half to three and a half inches long, and resemble lily flowers. Foliage only appears after flowers deteriorate, and lasts only until weather gets warm late in spring. The strap shaped leaves are about a foot to a foot and a half long. Through summer, the two or three inch wide bulbs are dormant and bare, and seem to be dead with their tops visible at the soil surface, but retain fleshy roots below. They should therefore only be dug and divided if they get too crowded or need to be moved.

Delay Some Gardening Between Seasons

Pruning should not leave bark of inner stems exposed during such warm weather.

For gardening, this is one of those in between times of year, when summer chores are under control, but it is a bit too early for much of the work that will need to be done in autumn. Automated watering systems have already been adjusted for the longest and warmest days of summer, so will only need to be adjusted the other way as days eventually get cooler and shorter. Growth of most plants slows; and some of the plants that will later be the earliest to show fall color begin to fade from bright green to paler green.

The last of the summer fruits should be gone, leaving the trees that produced them looking somewhat tired. The weight of large fruit, particularly peaches, might have pulled stems downward where they may now be obtrusive. Pruning a few minor stems should not be a problem. However, trees are still too vascularly active for major pruning. That needs to wait for dormant pruning while trees are bare in winter.

A few plants with sensitive bark are susceptible to sun scald if pruned to expose too much bark on interior stems while the sun is still high and warm. This is not so likely to be a problem if pruned during winter because the sun is lower and cooler, and foliage grows back before the following summer. Actually, that is why English walnut and various maples are able to defoliate during winter, even though their smooth bark needs to be shaded.

Pruning of plants that are potentially sensitive to frost should likewise be delayed. Otherwise, pruning is likely to stimulate development of tender new growth that will be even more sensitive to frost during winter. Besides, new growth develops slower this time of year, so plants look freshly pruned for a longer time than if pruned late in winter, just prior to spring.

Some types of pittosporum are more susceptible to disease if pruned in late summer or autumn because their open pruning wounds heal slowly and stay open to infection during rainy winter weather. However, slow recovery from pruning can be an advantage to formally shorn hedges that are not so sensitive to frost or disease, such as the various boxwoods, or glossy or wax privets. If shorn now, they might stay trim until spring.

The dried foliar remains of any summer bulbs that are finished blooming can now be plucked and disposed of. Gladiolus and montbretias that are still green can be deadheaded (pruned to remove deteriorated flower stalks), but should be allowed to turn completely brown before getting plucked. Watsonias are not so easy to pluck without also pulling up the bulbs, so should instead get their dried foliage pruned off.

Weeds outside of landscaped areas may not seem to be a problem, but many are now producing seed that gets blown into the garden. Even if such weeds do not need to be pulled, their flowers and seeding stalks should still be cut off and removed if possible.

Horridculture – CH CH CH CHIA!

This recycled article reminds me of how fortunate I am to live in a forest.

tonytomeo's avatarTony Tomeo

P80829Skyscrapers are already very efficient. They fit more usable floorspace into their ‘footprint’ than any other type of building does. They conserve energy that gets used for heating and cooling by exposing less of that floorspace to the outside weather. For all that usable floorspace, they need only a single roof.
Think about it. A relatively short ten story building contains as much floorspace as ten single story buildings that occupy the same area individually, but collectively occupy ten times as much area! Nine of those stories loose heat during cold weather, and collect heat during hot weather, only around the exterior walls. Only the top floor loses and collects heat through the roof, and only if there is not an upper utility ‘attic’ floor that insulates it. Ten single story buildings of the same area are all exposed on top, as well as all the way around. Of course…

Saint John’s Wort

Saint John’s wort blooms somewhat late.

Although it shares the same common name, Hypericum beanii is not the same sprawling Saint John’s wort that is now so aggressively naturalized within some local ecosystems. It is shrubbier and much more docile. Mature specimens get no more than three feet high and wide. It should be evergreen here, but can get sparse through cooler winter weather.

Bloom begins in the middle of summer and continues at least to early autumn. Cheerfully bright yellow flowers are two inches wide, with five rounded petals around fuzzy centers. The light green and oblong leaves are about two inches long. Stems are rather wiry, and can eventually get shabby. Coppicing as winter ends stimulates fresher vigorous growth.

Saint John’s wort prefers sunny and warm exposure. It is otherwise not very demanding. Regular watering enhances bloom. Yet, established plants can survive without watering. Where coppicing (cutting back to the ground) in late winter is not a problem, Saint John’s wort performs well as a low hedge, or unshorn border. Frequent shearing inhibits bloom. Rust is a potentially bothersome fungal disease.

Late Summer Bloom Until Frost

Some flowers bloom at odd times.

Seasonal changes keep gardening interesting. Like colors of a rainbow, seasons are not as distinct as their dates on a calendar imply. Each evolves into the next. Spring evolves into summer. Late summer is presently evolving into autumn. It happens like red evolves into orange on a rainbow. It is amazing that plants can monitor the changes so precisely.

Even if plants could monitor calendars, they would not. They are too busy monitoring the daily duration of sunlight. That is how they identify primary seasonal changes. Of course, they monitor the weather also. That is how they know more precisely when to react to the seasonal change. Plants are aware that it is now late summer, and they know what to do.

Most but not all plants bloom during spring or summer, so finish by late summer. By now, they prefer to prioritize seed production. Some continue to produce fruit to entice animals who eat it and disperse its seed within. However, some plants prefer to bloom late. Some bloom during autumn or winter. Some are so late that they are early during the next year.

Therefore, there is more to provide floral color through late summer and into autumn than cool season annuals and late blooming perennials. Butterfly bush, plumbago, bee balm, lion’s tail, Saint John’s wort and various salvia are now blooming for late summer. Some might continue into autumn. Oleander and euryops might bloom sporadically until winter.

Strangely, some flowers that bloom for late summer or autumn are from tropical climates. Because equatorial or tropical climates are not as cool during winter, or may lack winter, shortening days are not such a deterrent to bloom. However, many tropical plants bloom sporadically, rather than profusely within a particular season, and may be unpredictable.

Princess flower, mandevilla, hibiscus and angel’s trumpet may bloom at any time prior to winter chill, but may not. Those that do so may not repeat the process annually. Fuchsias are a bit more reliable for late bloom with flowers that are generally more interesting than colorful. Blue hibiscus looks more tropical than it is, with potential for late summer bloom.

Horridculture – Agave

Again, due to an abundance of ‘Horridculture’ posts, this one got recycled today rather than on Wednesday, when ‘Horridculture’ typically posts.

tonytomeo's avatarTony Tomeo

06When they became a fad in the 2000s, it was one of the very few fads that was actually sensible for California. Agaves certainly are not for every landscape, and certainly do not suit everyone’s taste, but they are ideal for the climate here. In some regards, they are more practical than the more popular of the native specie that tend to be scrubby looking and short lived. Agaves really should have become trendy a long time ago.
The problem with the fad, like so many other fads, is that it caused the object of desire to be overly popular for a while. Many agaves consequently got planted into situations where they did not belong. Landscape designers often forced them into the gardens of clients who did not know what they were, or did not even like their bold style. To show them off most prominently, designers often put the…

Horridculture – DEATH

Due to an abundance of ‘Horridculture’ posts, this one got recycled today rather than on Wednesday, when ‘Horridculture’ typically posts.

tonytomeo's avatarTony Tomeo

P80815KIt is quite natural. Death, I mean. Every living thing does it at one time or another. Even the oldest bristlecone pines that live for thousands of years eventually do it. The Monterey pine in this picture did it quite efficiently. The three crows perched on top make it look extra dead. You know, not merely dead, but very dead. If this tree were in my own garden, I would be totally saddened by its death, but there is nothing that I could do about it.
The smaller dark objects suspended in the now dead limbs are pine cones. Monterey pine starts to produce pine cones at a young age, and of course, produces more with age and increasing size. As mature trees begin to deteriorate, they produce even more cones as they concentrate their resources into seed production for the next generation. This elderly tree knew that death was…

Six on Saturday: Cat Burglar

Is a cat burglar a kitty who steals things, or someone who steals from kitties? There are a few kitties here, and, apparently, a burglar. I determined that two of the kitties are appropriate for Six on Saturday because they have horticultural names. The burglar is less appropriate, and is gone anyway. I am quite annoyed that someone came here, likely during the day, and stole from us. A small hesper palm that I grew from a seedling, two specimens of golden bamboo, and a larger Mexican fan palm got taken.

1. Cat – Black Jack, like the oak, Quercus marilandica, has a good horticultural or arboricultural name. He is a solid black Maine coon cat, and is no more cooperative for a picture than Rhody.

2. Burglar – Hesper palm, Brahea armata, lived here, in the blank spot on top of the wall. Golden bamboo, Phyllostachys aurea, lived right behind it and in the blank spot four cans to the right.

3. Cat – Pepper, like a species of Caspicum, has a good horticultural name too. She looks something like a penguin with a bit of brown, but is no more cooperative for a picture than Black Jack.

4. Burglar – I know I brought back more shoots of this unidentified species of Aloe from my downtown planter box. At least these four remain. They will get groomed and return to the planter.

5. Canna – This also came from the downtown planter box. It needed to be removed to facilitate the repair of a few broken tiles. It will eventually return with the Aloe. This bloom is a surprise.

6. Vine maple – Acer circinatum is still healthy and reasonably happy after getting yanked from its landscape by a backhoe during the warmth of summer. I did not expect it to survive so well.

Black-Eyed Susan

Black-eyed Susan epitomizes prairie style.

A flower that is so prominent in American culture should have a more appealing name than black-eyed Susan. Even the Latin name, Rudbeckia hirta, sounds bad. Is Becky really so rude? Did she hirt Susan? Well, black-eyed Susan is good enough to be the state flower of Maryland, and is one of the most popular of flowers for prairie style gardens of the Midwest. After all, it naturally grows wild in every state east of Colorado. Here in the West, it is a light-duty perennial that is more often grown as an annual. As a cut flower, it can last more than a week.

In the wild, the three inch wide flowers of black-eyed Susan are rich yellow with dark brown centers, and can stand as high as three feet. The typically smaller but more abundant flowers of modern varieties can be orange, red or brownish orange, on more compact stems. Gloriosa daisies are fancier cultivars, with larger flowers that are often fluffier (double) or patterned with a second color. Individual plants do not get much wider than a foot, with most of their rather raspy foliage close to the ground. All black-eyed Susans bloom late in summer or early in autumn.
