If you are a very neat, tidy person, then white may be the color for you. Crisp flowerbeds of white will give your garden a well-planned look. Masses of white can be hard on the eyes, so you may want to incorporate other colors as well. White is the last color to fade as night falls. If evening is the only time you have to enjoy your garden, white flowers are a good choice because they can be seen and enjoyed as darkness falls.
Most flowers have white varieties.
Annuals that deliver good white blooms include petunia, wax begonia, nicotiana, alyssum, and impatiens. Green is a good compliment to white because it helps your eyes recover from the strain of bright white. Don't forget the shades of green in leaves as part of your color plan. Variegated or multi-toned leaves add a splash of interest, but extensive use tires the eyes. Just don't over do it.
