The best and brightest color in the garden is obviously still provided by flowers. Autumn color can be spectacular, but only amongst relatively few deciduous trees, shrubs and vines that turn color reliably in mild climates, and only if the weather is conducive to coloration. The next best option for color beyond green is the sort of colored foliage that does not wait for autumn to materialize.
Foliage can be shaded with varying degrees of yellow, red, pink, purple, bronze, grayish blue or gray, or variegated with white, yellow or silvery gray. Plants that display such colorful foliage can be as small as flowering annuals, or as substantial as shade trees. Many are deciduous plants that also turn color in autumn. Most of the best are actually evergreen, so hold their color through winter.
Color tends to be richest as new foliage emerges in spring, and fades more or less through summer. Gold junipers only start out gold, but then fade to green within only a few months. The purplish foliage of ‘Forest Pansy’ redbud fades to coffee stained green. Yet, bronze New Zealand flax is always bronze. Dusty miller is always gray. Some plants are more reliably colorful than others are.
Exposure is important too. Most blue or gray foliage, whether juniper, agave, spruce, eucalyptus, olive or silver Mediterranean fan palm foliage, will be significantly greener if shaded. However, white variegation of English holly, hydrangea, ivy, hosta and pittosporum have better contrast if partly shaded. Colorful Japanese maples color better with good exposure, but roast if too exposed.
Many plants with colorful foliage are notorious for developing greener mutant growth known as ‘sports’. Because sports have more chlorophyll, they grow more vigorously than more colorful growth does, and can overwhelm and replace the more desirable colorful foliage if not pruned out. Many types of white or yellow variegated euonymus, as well as the more intricately variegated New Zealand flax, can revert to monochromatic green within only a few years.
‘Cide’ as a suffix that designates something to be killed. ‘Insecticide’ kills insects. ‘Miticide’ kills mites. ‘Molluscicide’ kills molluscs such as snails and slugs. ‘Herbicide’ kills herbaceous plants, which are presumably weeds. These examples and other chemicals that kill things that are considered to be pests are collectively known as ‘pesticides’. Many are potentially useful in the garden, since that is where so many familiar pests are problematic.
There is some debate about the origin of the common name of Confederate jasmine. Some attribute it to its popularity in the former Confederate States of America. Others believe it originated in the Malay Confederacy, much closer to its native range. That is irrelevant here, where we know this popular vine with very fragrant flowers simply as star jasmine, Trachelospermum jasminoides.
Vines in the wild are downright exploitative. They do not support their own weight, so instead climb or sprawl over shrubbery and trees. Some are satisfied staying down below the canopy of the hosts who support them, as if aware that a healthy host will support them for a good long time. Many vines climb aggressively to the top and overwhelm their hosts, even if it eventually kills them.
They were impossible to miss. They came at a weird time too.
No, this is not a Paris daisy. It is a common euryops daisy, Euryops pectinatus. It is obviously related, but the flowers are bright yellow rather than clear white with yellow centers, and the foliage is darker green. It is more resilient, so became more common in landscapes as quickly as mow, blow and go ‘gardeners’ replaced real gardeners who actually know something of horticulture. There is certainly nothing wrong with it. It is just cliché.
‘Shrubbery’ sounds so unflattering for a pine; but mugo pine, Pinus mugo, is not really much of a tree. The tallest trees do not reach eaves. Most old trees are only a few feet tall and about twice as broad, with strictly rounded form, and dense forest green foliage. The stout paired needles are only about one or two inches long. The plump cones, which are rarely seen, are not much longer.
Not many plants are sensitive to mere heat alone. Actually, many plants prefer warm weather. The difficulty that some plants have with heat locally is that it typically accompanies aridity, and often accompanies afternoon breezes. As appealing as breezes and minimal humidity are to us while the weather is warm, they promote and accelerate desiccation of exposed sensitive foliage.
Pluots, plumcots, apriums and peacharines! Who comes up with this stuff?! Aren’t good old fashioned plums, apricots, peaches and nectarines good enough? Who decides that these weird hybrids are somehow better than their parents? Some of them are actually quite weird, or downright ugly. Several do not even look like they would taste good. It may be an acquired taste; but I have all the good taste that I need without acquiring any more.
