Sporting one of the best burgundy foliage of all switch grasses, Panicum virgatum ‘Shenandoah’ is a deciduous, perennial grass of choice. It forms an erect, compact and narrow clump of steely blue-green foliage in spring, which quickly takes on red tones by early summer and turns violet, purple, burgundy and wine-red by early fall. It gets topped in summer with a profusion of finely-textured, reddish-pink flower spikelets which hover over the foliage like an airy cloud. Both flowers and foliage turn beige in fall and persist well into winter.

Like many North American prairie grasses, switch grass is a long-lived, warm-season grower. Quite sturdy, even when dry or dormant, it stands through winter (unless your area enjoys heavy snow falls), providing essential cover for birds.

  • Recipient of the prestigious Award of Garden Merit of the Royal Horticultural Society.
  • Typically grows in narrow clumps, up to 3-4 ft tall and wide (90-120 cm). Will slowly spread by underground rhizomes. May self-seed but may not come true from seed.
  • Welcomed in any garden style, it is versatile and can be used in groups or in mass plantings. It is ideal in borders where it provides texture, color and contrast. Excellent choice for prairies, wild gardens, along ponds and stream or in naturalized areas.
  • Performs best in full sun in average, medium to wet, well-drained soils. Tolerates part shade, but will lose its upright form in too much shade and may fall over. Tolerates a wide range of soils, including dry soils, but prefers moist, sandy or clay soils. Drought and wet soil tolerant!
  • No serious insect or disease problems. Deer resistant.
  • Requires little maintenance except cutting back the old foliage to the ground in late winter to early spring.
  • Propagate by division in spring
  • Panicum virgatum species is native to North America.
