WHAT: Calamagrostis acutiflora Karl Foerster, a feather reed grass, is valued for its early bloom time and architectural form, slightly tighter than other forms of feather reed grass. In June feathery flower stalks of pinkish bronze rise to 6 feet tall and change to a gold color as they mature through the summer and persist well into winter.
WHY PLANT IT: This grass adds structure to the garden without being overbearing. It is slow spreading and will not seed around the garden. Once established only occasional watering is needed during dry weather. Keep fertilizing to a minimum to prevent flopping seed heads. Cut this grass to the ground in late winter when seed heads look unattractive and before new growth starts.
WHERE: Feather reed grass grows best in full sun with well-drained or sandy soil. It will tolerate clay if it is not waterlogged in winter.
SIZE: This deciduous plant grows to 2 feet tall by 1 foot wide.
