Variegated plants have part of the normal green portion of the plant leaf being replaced by white, cream, yellow, or occasionally other colors. How cool is that!
As a design element, variegated plants are often used as the center of attention or as a focal point in the landscape to lighten up a normally dark space.
Plants with bold variegation seem to scream for attention in the garden, hence their use as accent plants. As with all brightly variegated plants, they show off best when contrasted against a dark background. Whether planted against a mostly green hedge, or a larger backdrop of deciduous trees, some background is needed to properly display variegated trees, shrubs and perennials.
