Lantana camara

The foliage is oddly aromatic.

Even as most flowers of summer are finishing, the bright yellow, orange, red, pink and white blooms of Lantana camara continue to brighten gardens until the weather eventually gets too cool and damp for them to perform. This is quite impressive for a species that is endemic to the tropics of Central America, and has a taste for warmth. Blooms are actually one to two inch wide umbels of many small flowers. Individual flowers within each umbel may be different colors at different phases, so that each umbel may have blooms in as many as three different colors.

In the wild, Lantana camara can get almost six feet high and more than six feet broad. Garden varieties are of course much smaller and compact. Since Lantana camara does well in containers, a few cultivars that stay very compact and proportionate to container gardening have been developed, but unfortunately remain somewhat uncommon in nurseries. The potentially objectionably aromatic leaves are about two or three inches long and one or two inches wide, with minor serration and slightly sandy texture. Some dislike the foliar aroma, but many enjoy it.

Lantana camara is not too demanding, wanting only good warm exposure with no more than a bit of shade. Once established, it does not need much water, and can actually rot if watered too frequently, or if soil does not drain adequately. Excessive fertilizer will inhibit bloom. There are not many insects that bother Lantana camara, perhaps because it has an unpleasant flavor. It is actually toxic to animals that may try to eat it. However, butterflies really dig it.

Catnip?

Is this actually catnip?

Is this catnip, Nepeta cataria? Again, I am baffled by something that should be very easy to identify. It certainly resembles catnip visually. It almost smells like catnip. If I did not get it from a small curbside garden that Rhody and others of his species leave messages for each other in, I would have confirmed that it tastes like catnip. Perhaps I should be more than adequately convinced that it actually is as I suspect.

Nonetheless, I am not yet convinced. Catnip is rare here. I know of no one who grows it. Those who have tried ultimately found it destroyed by frolicking cats. It really should be grown in hanging pots that cats can not reach. It seems unlikely that it could survive for long within a curbside garden near where a few cats live. It also seems unlikely that it would spontaneously appear where it had not been planted intentionally. Only small succulents were planted below a large camellia within its particular small garden. All the small weeds that grow nearby are common.

Regardless, I could not ignore a branched stem of this questionably identified species that had broken off and was laying limply over undamaged foliage. Obviously, it needed to be removed. Obviously, I obliged. I brought it back and processed it into several small cuttings. I collected the scraps of leaves and internodes for an associate to take to a feline acquaintance of his for possible confirmation of its slightly questionable identity. I await the assessment, although it will be from someone who can not decide to stay inside or go outside after meowing incessantly for someone to open a door. A second or more opinions may be necessary from other members of this innately indecisive species if the first attempt at confirmation is unsuccessful.

The foliage certainly resembles that of catnip.

Lantana

Lantana exudes a pungent foliar aroma.

Bloom continues as long as warm weather continues. Within warm exposures within the mildest of climates, it does not stop for long. Within cooler climates, Lantana camara may already be decelerating its bloom. Although remarkably resilient to arid warmth, it can be vulnerable to frost farther inland. Once established, lantana does not require much water.

Umbels of several tiny tubular flowers are about an inch and half wide. Individual flowers bloom progressively inward from the edges of their umbels. They are typically yellow, but then fade to orange, red or pink. Blooms therefore develop yellow centers within orange, red or pink edges. One cultivar is uniformly bright yellow. Another fades to creamy white.

Old fashioned lantana can eventually grow six feet tall. Congested old specimens might respond favorably to coppicing after winter. After coppicing, new growth can grow six feet high within its first season. Modern cultivars are generally shorter and relatively compact, and a few sprawl. Their very slightly raspy foliage is pungently aromatic when disturbed.

Martha Washington Geranium

Martha Washington should be quite pleased.

Mrs. George Washington never grew Martha Washington geranium, Pelargonium X domesticum. It was hybridized in Europe from south African species after she passed away. Although classified as a hybrid species, it is actually a group of distinct hybrids. Most are related to the same pair of primary ancestors. A few other species mingled in the process though.

The largest cultivars do not get much taller than three feet. Some develop rather irregular form. A few grow upward only to fall over. Minor tip pruning can improve awkward form. Stems are woodier than those of common zonal geranium. Consequently, cuttings do not develop roots as efficiently. Old specimens are less likely to recover from major pruning.

Martha Washington geranium may not bloom quite as profusely as zonal geraniums. The flowers are more spectacular though. Floral color can include purple, lavender, pink, red, burgundy or white. Billowy flowers are bordered or blotched with alternate colors. A few flowers bloom together on rounded umbels. Evergreen foliage is light green and ruffly.

Zonal Geranium

Zonal geraniums bloom colorfully through summer.

Where winters are cooler, zonal geranium, Pelargonium X hortorum, performs as a warm season annual. It is perennial only with shelter from frost. Locally, traditional cultivars are so reliably perennial that they can get congested without thorough pruning and grooming after winter. Frost occasionally ruins outer growth, but rarely kills entire plants with roots.

Modern cultivars bloom more profusely and more colorfully than old cultivars, but are not quite as resilient. They are more likely to rot during the damp and cool weather of winter. They bloom exquisitely from spring through autumn though, with bright hues of red, pink, peach, salmon and white. They stay lower and more compact, so require less grooming.

The more popular modern zonal geraniums should not get much more than two feet high and wide. Their small flowers bloom on globular floral trusses that can get as wide as six inches. Traditional zonal geraniums get bigger, with smaller floral trusses. Nearly circular and aromatic leaves generally exhibit darker halos between lighter centers and margins.

Red Ironbark Eucalyptus

The pendulous foliage of red ironbark eucalyptus moves softly in the breeze. The tall, curvy trunks are elegant and sculptural.

The many varied eucalypti never seem to outgrow the bad reputation of the blue gum and red gum eucalypti that get too big, messy and dangerous for urban gardens. Fortunately though, most others do not get nearly as large, and many stay proportionate to urban gardens. Their smaller canopies are neither as messy, nor as structurally unsound. Their adaptability to so many California climates and tolerance of aridity are serious advantages.

Red ironbark eucalyptus, Eucalyptus sideroxylon, is one of the mid-sized eucalypti that can eventually get quite tall, so is probably best where it has room to grow. Pruning for containment in compact gardens is actually quite a bit of work. Their coffee colored and deeply furrowed bark on elegantly sculptural trunks and limbs contrast nicely behind the mint frosting colored and softly pendulous foliage. The lanceolate leaves are about five inches long and three quarters of an inch wide. Flowers are almost always pinkish red, but can be pink or white.

Lantana

Lantana just might bloom until frost.

Where winters are very mild, common lantana, Lantana camara, might bloom through all but the coolest of weather. It generally takes more of a break though. It could finish bloom at any time now, and resume at the end of winter. Where winter weather is cooler, foliage and perhaps stems may succumb to light frost. Growth should regenerate through spring. 

The tiny tubular flowers bloom inwardly from the margins of round umbels that are about and inch and a half wide. Flowers typically bloom yellow, and then fade to orange, red or pink. Therefore, the umbels have yellow centers with orange, red or pink margins during the middle of bloom. One cultivar blooms with one hue of yellow. Another fades to white.

Modern cultivars mostly stay rather low and compact. Some sprawl. Older cultivars might get as tall as six feet after a few years. However, after frost damage or coppicing, mature plants may regenerate from their roots, with vigorous stems that get six feet long through summer. The faintly raspy foliage appears to be smooth, and is aromatic when disturbed.

Catmint

Catmint bloom is like faded denim.

Cats prefer catnip. It makes better tea too. Catmint, Nepeta X faassenii, is prettier though. It sprawls over the ground to get about three feet wide, without getting more than two feet deep. Where well exposed, it may not get much deeper than one foot. The aromatic gray foliage is denser than that of related catnip. Its individual leaves are small and furrowed.

Bloom begins with warming spring weather, and continues until cooling autumn weather. Individual flowers are tiny, and suspended on small floral stems. They just happen to be very abundant. Warmth stimulates phases of exceptionally profuse bloom. Floral color is light or pale blue, like faded denim. Shearing to deadhead enhances profusion of bloom.

Catmint works well as a rustic border or a ground cover for small areas. Alternatively, the blue bloom can be a delightful component of mixed perennials, in beds, planters or pots. Deer generally ignore catmint. Bees most definitely do not. They swarm it! ‘Walker’s Low’ is the most popular cultivar. It may be all that is available in some regions. Catmint is sterile, so generates no seedlings.

Lantana

Lantana sports two colors per bloom.

All flowers that need help with getting pollinated do what they can to attract pollinators. The tiny flowers of lantana, Lantana camara, actually put forth a bit of extra effort to improve the efficiency of their pollinators, by becoming less attractive once pollinated. Within each tightly set flower cluster, pollinated flowers fade to an alternate color to inform pollinators that their services are no longer needed. This prioritizes flowers than still await pollination. Consequently, each small cluster exhibits flowers of two different colors. The choices are red, orange, yellow, pink, purplish pink or white.

The small and aromatic leaves are arranged in alternating pairs on thin stems that do not get much higher or wider than three feet. Established plants can survive with very minimal watering, but bloom better with somewhat regular watering. The summer bloom is very attractive to butterflies.

Trailing lantana, Lantana montevidensis, has limber stems that sprawl a few feet over the ground without getting a foot deep. It cascades nicely over retaining walls or from large planters. Flowers are shades of lavender, or sometimes white.

Rosemary

Trailing rosemary cascades over retaining walls.

It is as familiar for culinary application as it is for home gardens, even with its new name. Rosmarinus officinalis is now known as Salvia rosmarinus, but the common name is still just rosemary. Like many Mediterranean culinary herbs, it is a member of the Lamiaceae Family. Since it is native to Mediterranean regions, it is quite happy within local climates. 

While many culinary cultivars of rosemary are shrubby or upright, the most popular home garden cultivars are trailing types. Trailing rosemary disperses its woody stems laterally, but can eventually get deeper than two feet. Shrubbier cultivars get at least twice as high in less time. The finely textured dark green foliage is evergreen and pungently aromatic.

Bloom is generally most profuse from late spring through the middle of summer, but may never really stop. It can continue in sparser sporadic phases whenever the weather gets warm, and even throughout the year. The tiny flowers are various shades of blue. Purple, white and pale pink bloom is very rare. Bloom is appealing to bees and other pollinators, including hummingbirds.
