Many purple perennials can be used to add a purple touch to your garden or landscape. Adding darker shades of purple lends a regal dignity to the landscape, while lighter lavenders may soften garden features. Purple perennials can be used to make eye-catching trellises, lacy meadow-like beds, attention-drawing driveways and ground covers for larger areas.
The pendulous lavender blooms of wisteria vines draped softly over a sturdy trellis or arbor create an inviting spring attraction that can become a focal point of your landscape. The bold, deep purple of clematis vines is another eye catcher that will adorn your trellis year after year in a display that requires only light pruning to maintain its attractiveness.
Rocky Mountain Meadows
The bluish-purple accent of Rocky Mountain meadows can be simulated for a rugged western look. Intermix deep blue Campanula glomerata, tall purple dame's rocket, pale bluish-purple lavender, and blue and white Colorado columbine with purple and yellow pansies and white ox-eye daisies for contrast. Provide a backdrop for your garden area by using with a split-rail fence. This display will make a light, lacy, meadow-like border that hints of western hospitality, tempting visitors to "come on in and set a spell."
Let lilacs stand sentinel on either side of your driveway entrance for a bold display of purple that will make your driveway stand out to passersby and put off a fragrant greeting for all who choose to enter. Lilacs are available in shades from light lavender to deep, royal purple. To increase blooming the following year and give lilacs a more uniform shape, lightly pinch back above points where buds are forming, and cut out dead or weak wood after blooms are spent.
The lilac mauve clusters of scaevola form mats 4 to 6 inches tall that eventually reach 3 to 5 feet in diameter, bursting with wide, fan-shaped flowers. These clusters can provide a evergreen ground cover that will bloom nearly year round in mild climates. Ground morning glory also provides a lavender-blue ground cover 1 to 2 feet high. It will spread to 3 feet or more from June to November. The lavender-blue, ½-inch blooms of catmint make an attractive summer ground cover display.
