Panicum virgatum, commonly known as switchgrass, is a perennial, deciduous grass native to the prairies of North America. In gardens, it’s particularly valued for the upright foliage, masses of hazy flowers in early autumn followed by gorgeous autumn colour.
Panicum virgatum ‘Shenandoah’ is a lovely variety with green blades, the tips of which turn carmine-red in early summer. Pink-red flowers then appear in early autumn. It looks fabulous planted in bold clumps that can sway in the breeze. Later in autumn the foliage turns a dramatic shade of yellow.
