Colors definitely have tremendous effects on our senses. And, since color dictates emotions, you want to select colors for your garden that suits the mood you wish to express. If you desire a healing garden that invigorates, or exudes passion, include complementary colors. Do that by selecting low-maintenance annuals and perennials in reds, violets, orange, and bright yellows to provide stimulation and to add drama.
If your preference leans towards a tranquil setting, whites, pinks, and pastel shades, invite a calming atmosphere. Green, as the dominant color in any garden, is useful in harmonizing plants with the various structural elements like screens, trellises, fountains, bird feeders, and pots.
