Chasmanthium latifolium ‘River Mist’ is another plant whose charms are not revealed well in a photograph. This variegated selection of Northern Sea Oats, an American native grass with a bamboo likeness, has light and lovely white striped foliage/seed heads, and performs a graceful dance in the garden with any gentle breeze. It does particularly well in light shade and is stunning used en masse or as a vertical focal point in containers. The foliage forms clumps 12-15″ tall and 24″ wide. 30″ stalks bear the showy striped seed heads in late summer and early fall. Take advantage of siting ‘River Mist’ where backlighting will add drama to the display, or use it against a darker shades to set off the white striping.

The objection some may have to this attractive native grass is that it does self-sow, though perhaps not as vigorously as the straight species, and the seedlings are usually not variegated. What one should do to avoid the unwanted seedlings is to cut the attractive flowering stalks for flower arrangements.  Plants are tough and hardy in zones 4-9, making them suitable for gardens throughout much of the U.S.
