June is Perennial Gardening Month
This year the Perennial Plant Association has named the Perennial of the Year as Schizachyrium scoparium, or Little Bluestem.
Summer through fall, the slender leaves and stems of little bluestem are an ever-changing kaleidoscope of gray-green, blue, pink, purple, copper, mahogany, red, and orange tones. Wispy silver-white seed heads sparkle in autumn sunlight and coppery brown leaves persist through winter.
Little bluestem is a tough and dependable clumping grass that blends well with perennials such as asters, sedums, coneflowers, and other grasses. Native grasses play their part in the pollinator story too. Little bluestem is a larval host for a variety of butterflies and moths such as crossline skipper, Dakota skipper, and Ottoe skipper.
Native to a broad swath of North America, it was one of the dominant grasses of the vast tallgrass prairies. In average to lean, well-drained soils, stems will remain upright but can flop easily if conditions are too rich or moist. Cultivars have been selected for shorter plants, enhanced leaf colors, and stronger stems.
Little bluestem’s spikiness complements native and non-native perennials alike. An easy fit for mass plantings or meadows, it is just as brilliant in traditional borders, gravel gardens, and green roofs. Perfect partners are recent PPOYs such as Calamintha nepeta ssp. nepeta, Asclepias tuberosa, Stachys ‘Hummelo’, and Allium ‘Millenium’.
