Striking flower spikes rise above the foliage in spring to late summer. Purplish at first, the flower plumes turn to a tan color as the season progresses. Evergreen in mild winter areas, Pacific Reedgrass is native to western North America, from Alaska to central California, where it is mainly a coastal species growing in moist areas such as beaches and wetlands.
