Chasmanthium Grass (Northern Sea Oats Grass)

Chasmanthium latifolium

Attractive, bamboo-like foliage and dangling, flat flower spikes create a showy accent around water features. Foliage turns coppery in fall, brown in winter. Provides a haven and source of food for birds and wildlife. Takes wind and ocean salt spray. Thrives in moist sites, yet quite tolerant of dry conditions when grown in shade settings.
