There is a large range of plants with colored foliage available to the gardener today. Reddish-purple, golden-yellow, silver, and grey-leaved plants, not to speak of the many types of variegated leaf, abound in nurseries and garden centers. Amongst all the plant forms - from trees to ground covers, one can find varieties that have brightly colored leaves. The challenge is to use them wisely and not be carried away by false notions of novelty or originality.
In fact, peppering the garden with such plants is the first sign of design naïveté. Green is the foliage color that should dominate most planting schemes, while plants with colored foliage should be used very sparingly as an emphasis, a contrast, and even a focal point in the garden.
There are of course endless variations of unusually colored leaves, but they can be reduced to four main groups. As a gardener in a Mediterranean country, I will restrict my examples to those with which I am familiar.
*Red or deep-purple foliage generally creates the most striking effect, but over-use can make the garden look depressing and somber. Prunus pisardii is a small plum tree, while the large shrub, Cotinus coggygria, is well known beyond Mediterranean climates. For mild winter regions, I suggest Euphorbia cotinifolia, which if kept at about 1-2 meters by annual pruning, is particularly beautiful. Let's not forget also, the mainstay, Berberis thunbergii.
It may also be worth considering bedding plants with red-purple foliage, such as the varieties of Joyweed (Alternanthera) which can really "hold" an herbaceous border through the long, hot, Mediterranean summer. This plant should be used as an annual anywhere but in the mildest of winter climates.
* plants with golden-colored leaves make for a less dramatic, but perhaps more subtle contrast with the mass of green foliage. For subtlety, it is best to study the size and shape of the leaf, before rushing in with a colored plant. These should be as similar as possible to the green-leaved plants. Hence, the feathery texture of Melaleuca "Revolution Gold" or Melaleuca "Green Dome", combine well with junipers for instance and other species of Melaleuca.
An amazingly beautiful shrub is Duranta erecta "Golden". It has small, oval leaves, and so goes well with such shrubs as Cotoneaster, Sumac, Pistachio, and Myrtle. planting it next to a course-leaved bush like Hibiscus, would be a mistake in my view.
*plants with variegated leaves are probably the most ill used amongst inexperienced gardeners. Again, the mistake is to plant too many of them, thereby turning the unusual into the common. They are most effective in shady corners, where they create a dappled-light effect, but they tend to look sickly in full sun,
*Grey and silver-leaves are perhaps easier to use without descending into banality. They are most appropriate in Mediterranean style gardens, but seem out of place amongst lush, tropical plants. Grey-leaved shrubs should be planted in very small numbers, although some species, such as Grey Owl Juniper, or the fabulous Texas Ranger (Leucophyllum frutescens) can be superb, especially in contrast to red-leaved plants.
Silver-leaved plants really come into their own in herb gardens, where they appear most at home. From an aesthetic point of view, in addition to a culinary or herbal one, plants like Lavender, Artemisia, and Sage are great, while grey-leaved grasses, such as Festuca glauca, are useful additions to an herbaceous border.
