Panicum amarum 'Dewey Blue'

Switchgrass or beach grass

This smooth, blue tinted grass can grow as tall as 4' and spreads slowly through its rhizome growth forming clumps. It was selected for its glaucous blue color, and graceful fountain habit. The flowers are airy, emerging in the fall, and persisting as a light beige color throughout the winter. Selected and named, by Rick Darke, for the lower Delaware beach town that bears its name. Native along the shores from Louisiana to Connecticut. It is adapted to dry, sterile locations where it plays an important role in stabilizing.

Switchgrass Interesting Notes

This is a low-maintenance landscape plant; however, because of its size and rhizomous growth habit, adequate space is essential. Bitter panicgrass is commonly found on high dunes and plays an important role in dune stabilization.
