Feral Vegetation Inherits Natural Advantages

Feral alyssum is limited to white.

Most vegetation within home gardens is better than it was naturally in the wild. For many, systematic selection isolated the best from average populations. Selective breeding and hybridization improved many others. Some are too genetically compromised by breeding to produce viable seed. Feral progeny of those that are not demonstrate the divergences.

Such feral progeny are generally not true to type. They are, to varying degrees, more like their ancestors than their direct parents. Some can revert directly to a natural state in the first generation. Some do so slower through a few generations. Feral progeny of hybrids are still hybrids but may be more primitive. Many hybrids produce no viable seed though.

‘Jewel Mix’ nasturtium, for example, blooms with many shades of yellow, orange and red. Several are pastels. Some are dark enough to be almost brown. A few are bicolors. Their progeny though, blooms with less light, dark and red colors. Bloom becomes exclusively bright yellow and orange as feral plants replace originals. It reverts to more natural color.

That is because nature is efficient. By human standards, innately unnatural breeding and selection improve plant life. They produce better fruits, vegetables, flowers and anything that grows on plants. However, they interfere with natural function such as reproduction. Seedless limes, which are preferable within home gardens, would go extinct in the wild.

Plants that revert to more natural feral states are merely trying to survive. Sterile pampas grass is only sterile because it is exclusively female. Naturalized Andean pampas grass can pollinate it from a distance, though. Their hybrid but nonsterile feral progeny may be as invasive as their Andean parent. They are detrimental to their ecosystem, but survive.

Not all feral flora grows from seed. Seedless and thornless honeylocust are grafted onto wild honeylocust understock. Seedy and thorny suckers can grow from such understock below its grafts. They commonly develop after removal of original grafted trees. By some standards, they become aggressively invasive. By other standards, they are sustainable.

Reveille

Angel’s trumpet, Brugmansia X cubensis ‘Charles Grimaldi’

Summer has been slow to arrive. Now, some flowers that have been waiting for a bit of warmth to bloom are ready to make up for lost time.

These angel’s trumpets are fortunately silent. Even prior to full bloom, so much bloom looks silly with such minimal foliage.This picture is a few days old; so they are in full bloom by now. More foliage will develop as the summer progresses.

This particular cultivar is the common ‘Charles Grimaldi’, with splendidly fragrant single yellow flowers. Two other cultivars are blooming nearby. One is somewhat less vigorous, with single white but perhaps less fragrant flowers. The other is more compact than ‘Charles Grimaldi’, with double white and comparably fragrant flowers.

All were grown from cuttings, and have potential to grow like weeds. Six more of the cultivar with double white flowers were added to another landscape nearby. Several of both cultivars with white flowers are developing in the nursery, and will need homes either in the landscapes or neighbors’ gardens by next year. Another cultivar in the nursery may bloom with mildly fragrant single pastel orange flowers in the next few days, but we will not know until it actually does so. We have not seen it bloom yet. It could actually be another copy of ‘Charles Grimaldi’.

Daylilies are beginning to bloom now also. Like angel’s trumpet, they seem to have been waiting a bit longer than they wanted to, so are ready to bloom simultaneously in atypical profusion. I hope that such profusion does not compromise subsequent bloom, since they continue to bloom throughout summer and until frost. Also like angel’s trumpet, daylilies are so easy to grow and propagate that there has been no incentive to acquire more cultivars than the three or so that are already here.

Six on Saturday: No Rhododendrons

Rhody’s rhodies were spectacular in bloom. This year, I refrained from posting too many pictures of them by posting none at all. I thought that I might get a few at the end of the season; but now find that the few that remain are either shabby or difficult to get a good picture of. There is plenty of other bloom though, even without exploitation of the warm season annuals. Now that daylilies are blooming, they will continue until autumn. Roses continue at least as late, but bloom in phases since most are partially shaded. All but one of these six species were recycled, although one was recycled by remaining where it was.

1. Daylily is not actually a lily. With all the bickering amongst botanists, its classification remains vague. This surplus from thinning a congested colony now borders the iris bed.

2. White climbing rose that was removed from the garden of a renovated cabin has been relocated to el Catedral de Santa Clara de Los Gatos, where merely white flowers bloom.

3. Rose lily that was plumply budded for Six on Saturday two weeks ago is now finishing. It recycled itself from a previous froufrou garden as the rose garden was installed over it.

4. Carpet rose was originally too close to a walkway, so was relocated to a wide roadside embankment. I am none too keen on carpet rose, but it is appropriate for its application.

5. Easter lily that was left from a wedding at el Catedral de Santa Clara de Los Gatos was added to the perennials across the road, but could have remained with the white flowers.

6. Unidentified hybrid tea rose, which had the color but not the form of ‘Double Delight’ before it began to fade, blooms in the rose garden, which was installed over the rose lily.

White Sage

White sage is so aromatic that it may be be objectionable to some.

‘White’ is not often associated with ‘sage’, since so many sages are known for the rich shades of purple, blue and red of their flowers. Others have lavender, pale blue, pink, yellow or ‘almost’ orange flowers. Compared to these, the whorls of small, slightly blushed white flowers of white sage, Salvia apiana, are relatively unremarkable, even though they are held as high as a foot and a half above the shrubby foliage on elegantly slender flower spikes.

However, the evergreen silvery foliage of white sage is quite remarkable both visually and aromatically. It is so aromatic that some people may actually find it to be objectionable. Those who initially grow white sage as an herb or for use as incense later realize that it also becomes a prominent ornamental, particularly with dark green foliage, like junipers or arborvitaes, to contrast with its strikingly silvery color. Mature plants get taller and wider than three feet, with simple three inch long leaves. After spring bloom, flower spikes can be shorn off to promote fuller foliar density. I prefer to prune stems back more aggressively to promote more aromatic vigorous vegetative (non-blooming) growth. These vegetative stems become less aromatic as they too eventually bloom.

Herbs Are Not Confined To Herb Gardens.

Spanish lavender is as herbal as English lavender.

While waiting for my white mocha at the White Raven coffee shop, I noticed white sage smudge sticks (incense) for sale. I also noticed that white sage is a component of at least one of the many herbal teas available. Although white is my favorite color, I am doubtful that it would be one of my favorite flavors. White sage seems to me to be much too pungent. I suppose that I should at least try it to satisfy my curiosity. Otherwise, the many other herbal teas included more docile but equally compelling herbs like sunflower petals, cactus flowers, chamomile, lavender, mint, catnip and various geraniums.

My mocha was ready too quickly, before I could investigate all of the herbal teas. Since I needed to get out of the way at the counter, I went to peruse the incense, where I again noticed some familiar herbs, like various sages, lavender, rosemary and bay laurel. A few plants that I do not commonly think of as herbs are common components of incense as well, such as juniper, cedar and pine. This was all too baffling; so I took my mocha to a table out front by a roadside garden, where I noticed some of the exact same herbs that I came outside to get away from!

All these fancy herbs and incenses and girly boutique beverages are simply not my cup of tea. Although at the White Raven, I know better than to be surprised by what might be in an excellent tea. Regardless, the garden out front is still more my style, and reminds me of how so many utilitarian herbs can also be very appealing ornamentals.

Rosemary, lavender and several of the sages are actually quite common in ordinary landscapes, whether or not anyone even notices that they have herbal merit. Some types of creeping thyme are sometimes used as ground cover in small areas, particularly around pavers or stepping stones where they release their fragrance if lightly trampled. Santolina and various yarrows and scented geraniums are less ordinary, but are similarly grown more often for their aesthetic value than as herbs. In my own garden, I really do not know what yarrow is good for. I like to add geranium leaves to sun tea, even if it makes it a girly boutique beverage.

Some herbs are almost too happy in my garden. The feverfew, chamomile and nasturtiums (my favorites!) that grew from seed from Renee’s Garden two years ago have spread outside of their area. I actually gave my mints away before they could escape. The catnip is confined to a hanging pot by the neighbor’s cat who gets sufficiently overindulgent to eradicate any self sown seedlings below. I never would have guessed that an inebriated cat could be so useful! Calendula, chive and oregano have all been grown from seed and become happily naturalized.

Feverfew

Feverfew blooms with many tiny daisies.

Historical herbal applications were the origin of its now silly name. Feverfew, Tanacetum parthenium, is a relative of chamomile. Its leaves are useful for herbal tea like floral buds of chamomile. Feverfew is delightfully aromatic, although some may disagree about how delightful it is. Some believe that it can repel unwanted insects, but may also repel bees.

Feverfew is likely more popular for its floral display than its aromatic foliage. Its abundant small composite blooms are very similar to those of chamomile. They are nearly as wide as three quarters of an inch. Their yellow centers are a bit flatter. Their ray florets (petals) are a bit wider. They bloom on open trusses that hover loosely above their basal foliage.

Feverfew has lime green foliage with a fine texture. It can stand almost two feet high with bloom standing a bit higher. It migrates slowly, but can slowly get where it should not be. Pruning scraps can root as cuttings. Feverfew prefers rich soil but does not need it. Good sun exposure and even watering are more important. ‘Aureum’ is bright greenish yellow.

Botanical Names Should Simplify Horticulture

Buick is a distinct automotive genus.

Botanical names of the vegetation that home gardening involves may seem complicated. Some are difficult to pronounce or spell. A few seem to be as lengthy as sentences. They seem to be a foreign language because most are Latin. Some are Greek. However, they are more valid than common names. What is common here might be uncommon abroad.

For example, Acer pseudoplatanus is a type of maple here in North America. However, it is a type of sycamore in England. Its common name is regionally inconsistent, so can be confusing. Its botanical name, though, is the same everywhere. Incidentally, Acer is Latin for “maple”. Pseudoplatanus is Latin for “false sycamore”. Technically, it truly is a maple.

Technically though, only a few cedars are truly cedars. Both deodar and blue Atlas cedar are species of Cedrus, which is Latin for “cedar”. However, incense cedar is a species of Calocedrus, which is a separate genus. Western and northern red cedars are species of Thuja, which is arborvitae. Again, botanical names are more valid than common names.

Nomenclature is a standardized application of names. Simple botanical nomenclature is binomial, which indicates that it involves two names. The first is the “general” or “genus” name, which is capitalized. The second is the “specific” or “species” name, which is not capitalized. Both are italicized. Species is singular and plural. Genera is plural of genus.

Botanical names are actually very similar to automotive names. Only italicization and the lack of capitalization of the species are different. Buick, Chrysler and Mercury are all like genera. Electra, Imperial and Grand Marquis are all like species. Sequoia sempervirens uses the same binomial format as Buick Electra. Botanical names really are that simple.

Many automotive species include variants, such as Limited, Custom and LSE. These are like varieties or cultivars of plant species. Such variants are evident by single quotes, but lack italicization. For example, ‘Soquel’ is the cultivar of Sequoia sempervirens ‘Soquel’. (‘Cultivars’ are ‘cult’ivated ‘var’ieties that are true to type only by vegetative propagation. Varieties can be naturally true to type by seed.)

Locusts!

the SWARM!

Well, not exactly locusts; although, until they were reclassified within the Order Mantodea, they were of the same Order Orthoptera as locusts. Nor are they affiliated with either honey locust, Gleditsia triacanthos that I wrote about for last Tuesday, or carob, Ceratonia siliqua that I wrote about for the previous Tuesday, and which is the sort of locust that sustained John the Baptist in the desert. These abundant critters are young mantises, which likely hatched shortly before posing for this picture that my niece took on her front porch. My niece had seen a slow moving adult mantis there last autumn, and guessed that it might have deposited eggs, and then later died in privacy. Fortunately, she enjoys all sorts of flora and fauna, and was not too disturbed by this scene, or by the mother last autumn, as even some who work outside might have been. In fact, to the contrary, she was pleased that their mother felt that her porch was safe enough for them to start their lives on. She knows that there are plenty of insects for them to eat within the vegetation that inhabits the landscape there, as well as in nearby landscapes. This many mantises will eventually disperse into the neighborhood to satisfy their voracious appetites as they grow. That is why mantis eggs are available for sale from some nurseries. They are beneficially predatory insects because they consume detrimental insects. Since their arrival, my niece did a bit of research on their sort, and found that some people actually raise certain rare varieties of mantises as pets. As weird as it seems, it is no weirder than pet tarantulas. Anyway, this picture was taken more than a week ago. These baby mantises are likely already growing fast and dispersing elsewhere into Los Angeles.
