Chasmanthium latifolium - Northern Sea Oats

Northern Sea Oats is a lovely woodland grass that is treasured for its showy, drooping flowers and slender, bamboo-like foliage which changes from green to copper in the fall. One of the few native grasses that grows well in shade. You can plant it in the border, shade garden, naturalized areas, along streams or on the edge of a water garden. Chasmanthium latifolium also grows well in large containers and is one of the best grasses for cut flower arrangements. Excellent both as a specimen plant and planted in masses.
