Feather Reed Grass 'Karl Foerster' (Calamagrostis x acutiflora)
Has a wonderful upright growth habit, making it very useful to place behind perennials with a spreading or rounded shape. The feathery plumes emerge in early summer and ripen to handsome wheat-colored seed heads by fall. Plant in groups of three or five for best effect.
Tough, hardy and easy to grow in full sun and average soil. No supplemental watering needed once established.
