How to Use Dark Foliage Plants

When it comes to gardening with dark foliage, the key is to keep it simple. Dark foliage plants (as well as black flowers) are striking, but too many can be overwhelming, thus completely defeating your purpose. One dark plant on its own stands out as a focal point in the garden, but you can also combine a few dark plants with bright annuals or perennials to highlight both. Dark foliage plants can really stand out when planted strategically amidst light-colored or silvery foliage plants. Dark plants show up best in full sunlight and tend to blend into the background in shade. However, not all dark plants do well in sunlight. If you want to plant dark plants in a shady spot, consider displaying them with contrasting, white or silvery foliage plants. Keep in mind that most plants with dark foliage aren’t pure black, but they can be such a deep shade of red, purple or maroon that they appear black. However, the depth of the color may vary depending on soil pH, sunlight exposure and other factors. Most importantly, have fun and don’t be afraid to experiment!
