Panicum virgatum ‘Shenandoah’ Switch Grass One of the best of the red Panicums, ‘Shenandoah’ was selected from ‘Hänse Herms’ seedlings by Germany’s Hans Simon. Emerging green in midsummer, slender leaves take on red hues and, come September, are thoroughly transformed. Paired with Echinops ‘Arctic Glow’, the wine-infused theme is echoed and, backlit by the long light of late afternoon, the glow is ethereal.

Blooms August–October.

Size: 4' high x 2'–2-1/2' wide; hardy to zone 4.
