Nursery contributed plant descriptions

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.
