In the Garden:
White blooms, like this coneflower, create a focal point for an evening garden.
Cool Off in an Evening Garden
When desert summer sun blazes overhead, thermometers read 105+ degrees, and humid air seems thick enough to carve and stack like bricks, sitting in the garden becomes more endurance test than relaxing activity. Don%t fight it. Instead, start planning an evening garden that features white and silver flowers and foliage. During summer%s intense heat, an evening garden becomes a welcome retreat after the sun sets.
White Flowers and Silver Foliage
Bright, intense flower colors like red and blue, although focal points during daylight, will fade away in the dusk. White flowers, on the other hand, appear to shimmer as the day slips away. Silver, gray or white-variegated foliage or white bark contributes a similar effect.
We are lucky to enjoy unique desert plants that are night-bloomers, waiting for the end of day to unfurl their flowers. Arizona queen of the night cactus is one example. Its striking white blossoms, accompanied by intensely sweet fragrance, act as beacons to lure pollinators who work the night shift.
For an eye-catching display, group whites together in drifts or odd-numbered clumps. The exception is a solo accent plant, such as as yucca with a tall bloom stalk, that will draw the eye wherever it is placed. As days shorten after the fall equinox, the same features can expand the hours spent enjoying the garden. Although there aren%t as many white bloomers for winter, silver foliage or intriguing white bark will do the trick.
