Six on Saturday: Oh Deer!

Deer have avoided the primary rose garden for longer than anyone can remember. They avoid a large colony of carpet roses nearby also. (The carpet roses were relocated across the road from where they were, but did not go far.) I thought that some old canned roses could be about as safe in another landscape less than half a mile of winding road away. I was wrong. The primary phase of bloom was harvested by neighbors who walk past that landscape. Subsequent phases are mostly consumed by deer. I was surprised to find that these flowers lasted long enough to deteriorate.

1. There is not much vegetation that deer will not eat. New Zealand flax is one of the few species they ignore. It is primarily a foliar plant though. Bloom looks like dinky bananas.

2. Carpet roses often manage to bloom regardless of the voraciousness of deer. Bloom is generally too profuse for deer to eat all the flowers. Unfortunately, I loathe carpet roses.

3. I believe that the color of this particular rose could be described as ‘peach’. I am not at all proficient with color, so this is merely a guess. This cultivar seems to be a floribunda.

4. This rose initially blooms brighter yellow before fading like this. Of course, I have not seen it fade much in the past. I am impressed that this flower lasted long enough to fade.

5. Two buds peeking over the edge suggest that this pink rose is a floribunda too, like the peach rose #3 above. I can not identify any of the cultivars of any of these recycled roses.

6. Rhody apparently shares my disdain for carpet roses. I realize that this is not the most flattering picture, but I also realize that the worst picture of Rhody is the best of my Six.

Blue Dawn Flower

Due to an inability to locate some of my old articles from nine years ago, I will recycle articles such as this, which already posted to this blog four years ago, through June and at least part of July.

70614Even within its native range, blue dawn flower, Ipomoea indica, can be a problem. There are not many other plants in some coastal regions of Peru that can avoid getting overwhelmed by the aggressive wiry vines. These vines grow roots where they touch soil, so can spread indefinitely over the ground. Vines that succumb to frost over winter regenerate as if nothing ever happened.

Three inch wide flowers are rich purplish blue when they open at dawn. They then fade through the day, only to be replaced by fresh new flowers the following morning. Bloom continues from spring until autumn, and can get profuse at times. The lush rich green leaves are cordate (heart-shaped) or lobed (with only three lobes). Too much fertilizer promotes growth but inhibits bloom.

Blue dawn flower’s main weakness is a dependency on water. If it gets too dry briefly in summer, it can die…

Annuals Just Might Be Perennials

Due to an inability to locate some of my old articles from nine years ago, I will recycle articles such as this, which already posted to this blog four years ago, through June and at least part of July.

70614thumbAnnuals come and annuals go. There are cool season annuals for winter. There are warm season annuals for summer. Really though, there are all sorts of annuals that are not annuals at all. Most are some sort of perennial that has the potential to last longer than a single season. Only a few popular ‘annuals’ would necessarily die after blooming and producing seed, within a single year.

To be clear, true annuals last only a single year. They probably germinate from seed early in spring, and grow quickly. They then bloom in spring or at least by summer, and subsequently produce seed. Once their seed has matured and been dispersed, their job is done. They finally die in late autumn or winter. Annuals from deserts are even faster because of the harshness of the weather.

Many large-flowered sunflowers are true annuals. They are finished once their seeds mature. They will…

Horridculture – Security Clearance

Hey, I grew my pineapple sage from cuttings from this sloppy mess!

tonytomeo's avatarTony Tomeo

P90619A well designed landscape should be an asset, not a liability. It should beautify and enhance the function of outdoor space, while harmonizing with associated indoor spaces. In order to continually do so, even a very well designed landscape requires maintenance so that it does not become so overgrown that it becomes unsightly and obstructive.
Some landscapes require less maintenance than others. There happens to be very few that can be allowed to grow wild, but only because their components are allowed the space they need to do what they do naturally. It is not fair to incorporate plants merely because they are appealing, and then expect them to conform to unnatural constraints without some degree of intervention.
As an arborist, I often see trees that must be pruned for clearance from roofs, gutters, walls, windows, lighting, utility cables and roadways. It is normal for trees and large shrubbery to…

Silver Mountain Gum

Silver mountain gum is remarkably glaucous.

The strikingly glaucous juvenile foliage of silver mountain gum, Eucalyptus pulverulenta, is likely more familiar within floral design than in home gardens. Actually, it is uncommon within home gardens, although quite popular as cut foliage among florists. Its paired and sessile leaves are oval or bluntly cordate (‘heart shaped’), and about an inch or two long.

Adult growth is rare, even among established trees. However, small white flowers bloom from the axils of juvenile leaves that are a year old. (Juvenile growth of most species can not bloom.) Bloom might continue from spring until autumn, as blooming stems sag from the weight of younger distal growth. The aromatic and evergreen leaves stiffen with age.

Low and shrubby specimens with a few trunks may not get much higher than fifteen feet. They have potential to get twice as tall though, particularly if pruned up onto bare trunks. Lignotubers expand below the trunks. Strips of old bark shed to reveal fresh matte brown bark. Incidentally, the Latin name of this species often transposes for Eucalyptus cinerea.

Drought Tolerance Necessitates Root Dispersion

Extensive root dispersion enhances drought tolerance.

Fads certainly complicate gardening. Most are merely marketing tactics. Most are bogus. Many even contradict their justifications! For example, most new, trendy and supposedly sustainable plant cultivars are genetically weak because of extensive breeding. Drought tolerance likewise has potential to be a constructive fad, but is so commonly misapplied.

Incidentally, its terminology is somewhat inaccurate. Drought is an extended but unusual pattern of dry weather. Whether the duration is for one year, or many, it is not permanent. The dry weather that persists through summer locally is normal for the chaparral climate. It is therefore a normal characteristic of climate, rather than abnormal weather conditions.

Drought tolerance is therefore practical here as chaparral tolerance. Most plants that are drought tolerant are naturally endemic to chaparral regions or deserts. Many of the native species naturally exhibit remarkable drought tolerance. Once established, they might not require any more moisture than they get from annual rainfall. Some prefer dry conditions.

Drought tolerance should not imply that such plants are undemanding. In some regards, they are more demanding and less adaptable than plants that require frequent watering. Such plants rely on extensive root dispersion to procure the moisture they require within dry situations. Most do not adapt to confinement, even if watering is enough to cause rot.

Container gardening is therefore a fad that is incompatible with drought tolerance. It only uses less water for plants that use more water. Also, modern drip irrigation, which is very practical for plants that rely on irrigation, requires a bit more effort for plants that use less moisture. To not promote rot, emitters must move farther from main trunks as plants grow.

Many of the most sustainable and drought plants are old fashioned sorts that became too common years ago. Fortunately, some are regaining popularity again. Some of the more compact eucalypti are proportionate to modern gardens. Grevillea, bottlebrush, rockrose, juniper, rosemary, salvia, lavender and New Zealand flax are as drought tolerant as they had always been.

Crop Circles

Goodness; now that I think of it, I have not seen cattle anywhere near here for a very long time!

tonytomeo's avatarTony Tomeo

P90616These are perfect conditions for crop circles. Even without any convenient grain crops, there is plenty of tall grass in unmanaged and ungrazed fields. All this grass needs is to be crafted into crop circles.
The first crop circles that I ever witnessed were made by cows. I was not much more than six, and my younger brother who found them was not much more than five. No one bothered to explain to us that cows were related to cattle who grazed nearby. Consequently, we had no concept of what cows were.
Earlier in the day, we had discovered what was described to us as a ‘cow pie’. Naturally, we were skeptical. It looked just like what cattle leave behind, which was not good. I was not about to try it, so got my younger brother to taste it. Apparently, it tasted about as bad as it looked. It seemed…

Pink Trumpet Tree

Yes, Brent takes bad pictures.

tonytomeo's avatarTony Tomeo

P90615K

This is why I do not often use pictures that my colleague, Brent Green, sends to me. He frequently tells me what I should feature in my gardening column, and sends me what he considers to be good pictures for such topics. This picture would have been good for writing about the sky over Los Angeles, or the neighbors’ driveway, since those are two of the most prominent features here. Where did all the smog go?

Chimneys in Los Angeles seem silly to me. Even if the weather got cool enough for a fire in a fireplace, there is no firewood to burn. The chimney to the far right certainly seems to be original to the house, but how did it survive all the earthquakes since the house was built, probably in the 1940s or 1950s? There have been a few moderate earthquakes since then.

Those signs that warn potential…

Six on Saturday: Bummer!

Things do not always go according to plans. Seasons and weather change faster than we can keep up. Many plants do what they want to do rather than what we want them to do. There is always compromise. It is a bummer that a unique agave is bolting now, and will eventually die, but it provided plenty of pups to replace itself with. It is a bummer that I must remove a productive elderberry bush before the berries ripen, but there are plenty more elsewhere. It is a bummer that two exemplary red maples may have died, but there are three more. The excess of recycled cannas is not a bummer though, but merely extra work.

1. Whale’s tongue agave was a splurge. The horticulturist who got it had been wanting to grow it for a while. However, two years later, it had a litter of pups and is now blooming!

2. The flowers are not even very pretty. At least the floral stalks are weirdly striking, and bloom slowly. Although monocarpic, it could take months for the original rosette to die.

3. Six big potted maples were installed temporarily last year. Three are red maple. Three are Norway maple. The red maples foliated before we made arrangements for irrigation.

4. Elderberries are developing nicely. These are some of the best. However, they are on a big healthy elderberry bush that must be cut back from a roadway before they can ripen.

5. Cannas are fun! I was pleased with an opportunity to recycle a bunch from a neighbor. However, this pile is HUGE! Well, I know what I will be doing this Saturday. Goodness!

6. These cannas bloom very nicely. Most are bright orange. Most of the rest are yellow. A few are red. Unfortunately, they are blooming in the big pile, unseen and unappreciated.

Western Azalea

Due to an inability to locate some of my old articles from nine years ago, I will recycle articles such as this, which already posted to this blog four years ago, through June and at least part of July.

tonytomeo's avatarTony Tomeo

70607We think of rhododendrons and azaleas as being from cooler and moister climates. After all, that is where they do best. Yet, there does happen to be a native western azalea, Rhododendron occidentale, that lives in the Sierra Nevada and coastal ranges from San Diego County to just southwest of Portland, Oregon. (Azalea and Rhododendron are varied specie of the same genus.)

Bloom is mostly white, with pink, pale yellow or golden orange. Some of the fancier garden varieties bloom clear white, or with more vibrant color. The lightly fragrant, two inch wide flowers bloom in groups of two or three on open conical trusses. Each truss produces as many as a dozen flowers in sequence, so a new flower replaces a fading flower for a bit more than a week each spring.

Western azaleas plants are unfortunately not much to look at after bloom. They grow somewhat slowly…
