Color combinations can be formal, with colors blocked out and clearly separated, or a more relaxed mix. That's the case with this pretty border of tulips, which neatly softens the space between a stone pathway and brick wall.
A grouping of two different hues of alliums showcases how two colors of a single flower can look distinctly different. The white version recedes, with less impact but a visually interesting. The deep purple globe, however, makes a more vivid impact.
Remember that foliage can add color, too. In this arrangement, a deep purple coralbells variety provides the anchor for this purple and white combo. The accompanying lamium does double duty, providing white for the combination in both flowers and the variegated leaves.
Lively and cheerful, this casual garden overflows with cottage-style loveliness. Flowers in various shades of purple and white, including clematis, delphinium, wishbone flower, dianthus, daisy, and sweet William, are accented by foliage-focused plants tinged with the same color combination, such as coleus and New Zealand flax.
Bold white tulips provide contrast to low-growing, spreading purple forms of lungwort and flowering spurge. To complement a color selection, consider using containers that repeat the same hues, such as this one that overflows with rich purple hydrangeas.
A simple way to create a harmonious color combination is to select two of the same plants in different colors. Here, purple and white colchicums, their blooms nearly identical, create a pretty springtime flower vignette
A duo-tone color combination need not blend the two hues in the same plant or intersperse the shades in a planned-out fashion. Here, pansies, in blue and dark purple, and sweet alyssum in white line the woodland flagstone path.
Colors in this flowerbed deftly transition from white (mixed with green) to lavender to a deep purple. There's a nice mix of flowers -- including purple angelonia -- as well as foliage-focused plants, such as tricolor sage and herbs purple basil. In fact, herbs can be an underused source of foliage and flowers in the garden, with the added benefit of providing a harvest, too.
Native plants offer lovely shades of purple and white while drawing butterflies and birds to a garden. This casually pretty collection combines coneflower, anise hyssop, and cleome.
Grouped by height, this garden segues from more spreading plants, such as purple verbena and dianthus, to taller bearded iris. That's a good guideline for easily creating visual interest without making garden design too complicated: Shift sections, particularly in beds that aren't too deep, based on how tall the plants grow.
