Gardeners pick and choose different colored flowers to turn a garden into a work of art. Purple flowers come in shades so pale they are almost pink up to deep dark hues. A garden composed of all purple flowers is far from monochromatic. Lighter shades also go well with dark-green evergreen plants. Dark purple flowers planted with white blossoms make both colors stand out more vividly. The options are only limited by the gardener's imagination.
Chinese wisteria (Wisteria sinensis) is a deciduous vine that climbs up tree trunks all the way to the canopy.

Purple foxglove (Digitalis purpurea) is hardy in USDA Zones 3 to 9. The plant takes two years to develop. In the first year, the plant produces dark-green or white leaves 5 to 10 inches long in a rosette pattern at the base. The second year, the plant produces flower stalks that grow from 3 to 5 inches tall with smaller leaves. It has tube-shaped flowers that resemble the fingers of a glove and grow up to 2 inches long.
