No other color gets as much attention as black. While black may be a staple in the fashion world, but isn’t quite ubiquitous in the garden world. Purist would argue that black is not a true color, rather it is the absence of light.

No other color gets as much attention as black. While black may be a staple in the fashion world, but isn’t quite ubiquitous in the garden world. Purist would argue that black is not a true color, rather it is the absence of light. Black creates interest, shows sophistication and adds a sense of opulence to the landscape. Although true black plants are a rarity in nature, there are many dark purples, dark reds, brown, dark greens and near, that come pretty close and black cultivars are being introduced at an increasing rate. Black plants are excellent for creating contrast and interest. Most gardens are a sea of green with flowers providing color and foliage giving contrast with textures and forms. Mixing in plants with dark colored foliage can really make a difference in the landscape or containers. Position them in light areas. Avoid hiding them in the shade where they tend to disappear. Pair black-foliage plants with lime, light greens, yellows, chartreuse, pinks and a variety of other colors for great effect. As they say in fashion, black goes with everything. Of course plants with purple leaves make a great contrast with plants with lighter foliage for visual interest, but dramatic designs can be created with all leaves for a very unusual effect.

Black foliage shows up best in full sun, so it is best to limit their use in shady spots. Using woody plants with black foliage can create a lovely backdrop for other plants and flowers or usually best used as accent plants, where they can be viewed up close. They can also be used as a focal point to highlight other colors in the garden. Purple foliage combines well with any other colored foliage, including blue, gold and silver for even more contrast. Putting a plant with dark purple leaves near another with bright chartreuse leaves makes the lighter color really pop. Variegated plants come more striking beside darker colors.

Flowers with strong, saturated colors tends to enhance purple foliage and hot colors, really make a statement against the black leaves which balance the shocking tones. Pairing black foliage with pastel colors adds a degree of sophistication and elegance. In a moon or (white) garden, black plants add contrast to the silver foliage and white flowers during the day, but at night they virtually disappear so the white pops even more. There are more than enough supply of plants- including annuals, herbaceous, perennials, trees and shrubs for nearly every growing condition-with cultivars that offer a change from green. Colors range from nearly true black to bright red, every shade of purple, maroon and brown in between.
