Bitter switchgrass

Panicum amarum 'Dewey Blue'

PAN-ih-kum ah-MAR-um Audio

A stunning, native dune grass, ‘Dewey Blue’ is perfect for coastal areas as well as inland gardens. Heat, drought, and humidity won’t faze its noticeably graceful habit. This grass has exceptional blue foliage and a vigorous constitution. Airy, light beige flowers emerge in late summer and fall, persisting well into winter for a long season of interest. ‘Dewey Blue’ grows 4 to 5 feet tall and almost as wide.

Noteworthy CharacteristicsAttractive powder blue foliage in a fountain-like form distinguishes this U.S. native beach grass.
