Repeat colors in flowers and foliage
As a designer, I wanted my garden to be both a teaching and test garden, so it contains many different plants. For them to look as though they belonged together, I used a unified color scheme. I chose a palette of mostly pastel hues—a gradation of bright and pale tones of pink, lavender, and purple, with soft, subdued shades of blue and yellow. Purple coneflowers (Echinacea purpurea), silvery blue lamb’s ears (Stachys byzantina), pink snapdragons (Antirrhinum majus), and yellow coreopsis (Coreopsis verticillata) are just a few of the annuals and perennials that fill my sunny borders.
However, to use the colors effectively, they had to be repeated in the shade garden. Here, witch hazel (Hamamelis virginiana) and lady’s mantle (Alchemilla mollis) add a touch of yellow, while old-fashioned bleeding hearts (Dicentra spectabilis) display delicate, drooping, pink blossoms. Astilbe (Astilbe X arendsii) offers plumes of pink, white, and rose, and Bethlehem sage (Pulmonaria saccharata ‘Mrs. Moon’) displays bluish-pink blossoms. But since most shade-loving perennials bloom for only a short time, I rely primarily on foliage for excitement and color in the shade garden. My astilbe is also valued for its often rose-colored foliage and, after blooming, the spotted leaves of Bethlehem sage enliven the garden until the first frost. I also appreciate epimediums and caladiums for their colored foliage.
A single plant used in repetition provides yet another visual connection. One of my favorites is the Japanese maple (Acer palmatum). I have different cultivars in sun and shade, but the deep, reddish-purple leaves and lacy foliage are echoed throughout the garden (bottom photo, opposite). On each side of the shaded garden path is a curved boxwood hedge. On a larger scale, 15 boxwoods (Buxus microphylla var. koreana) surround a display of daylilies in a sunnier section of the garden. And finally, another boxwood hedge delineates the end of the shade garden, where the lawn begins.
Diverse garden areas are linked visually by flagstone edging and a subtle color scheme.
Accent plants, like Japanese maple, are also repeated throughout the garden.
