Choosing the right colors for planter boxes in shady urban spaces can transform a dim corner into a bright, inviting retreat. The key is to select hues that reflect available light and create a luminous effect.
For maximum impact, white, cream, and very pale pastels are unparalleled. These colors act as natural reflectors, making foliage and flowers pop. Consider planters in glossy white or soft grey to serve as a neutral, brightening base.
When selecting plants, focus on foliage and flowers in light colors. Brilliant white impatiens, begonias, or nicotiana are classic choices. Don't overlook foliage; plants with variegated, silver, or chartreuse leaves (like hostas, heuchera, or lamium) add layers of light. For a vibrant punch, bright yellows and soft pinks can also penetrate the gloom effectively, especially from flowers like tuberous begonias or certain fuchsias.
Avoid deep, dark colors like burgundy, navy, or forest green for the planters themselves, as they absorb light. Instead, let those darker hues come from accent plants for contrast. By strategically using light-reflecting colors for your containers and plants, you can create a visually brighter and more cheerful shady urban oasis.
