Oakleaf hydrangea, snapdragon,
and sweet alyssum star in this
circular garden, but nuances of
lavender scabiosa, campanula,
delphinium, and saliva soften
white's glare.

White Plus One

Combined with any color, white has the impact of a mint sprig in lemonade: It adds an edge of refreshing crispness. White's chameleon-like nature also makes it the color companion valued most in the garden. Next to warm yellows and reds, white softens. With cool blue and purple, it appears frosty and defined. Free from color, white assumes whatever tint stands next to it.

Drifts of white in a red-hot border lower the temperature. A red-and-white scheme strikes a balance between excitement and relaxation. For a fresh-faced look, pair yellow or orange flowers with white blooms that have warm-color centers.

Planted next to receding blue flowers or foliage, white shines like a lightbulb in bloom, yet the overall effect is quiet and harmonious. Whites drawn from either variegated foliage or flowers become highlights when interspersed among green, particularly in a shady setting. Combined with pink, lavender, or silver, white appears enchanting. White roses peeking out among lavender phlox, or lavender clematis draped on a white arbor, look stunning at twilight.
