Panicum amarum ‘Dewey Blue’
at Digging Dog

Bitter Switch Grass


Switch Grass

The Panicums we’ve chosen are warm season prairie grasses native to North America. Resistant to heat, drought, and even extreme cold, Switch Grass boasts a cloud of inflorescences—a mystifying hologram of tiny red seeds that mature to black in late summer.

If grown en masse and not cut back until early spring, Panicums promise a lively winter show. After a frost, they stiffen and adopt the warm glowing color and soft rustling sound of wheat.

Populating Delaware’s coastal sand dunes near the town of Dewey, noted grass expert, Rick Darke selected this kingly Panicum for its blue, oh-so-blue smooth glaucous blades and elegant fountainlike stance. Distinctive straight-up stems bolster light airy plumes, followed by caramel-colored seed heads persisting well into winter. ‘Dewey Blue’ is not only a stunning showman but an enduring workhorse whose slowly spreading rhizomes form clumps that are vital in stabilizing seashore ecosystems, as well as withstanding hot dry summers and varied garden soils.

Size: 4' 0"–5' 0" high x 3' 0" wide; hardy to zone 3.
