Feather reed grass, Calamagrostis x acutiflora, is an upright grass with good year-round interest, bearing feathery plumes in summer and bleached stems catching frost through winter. Its architectural shape lends it to use as a striking focal point in gardens. It can form clumps of stems up to 2m high if grown in moist soil. 

Calamagrostis x acutiflora 'Karl Foerster' is prized for its stiff, erect habit, making it an ideal choice for planting en masse to form a screen, or in small groups to add height and definition to a border. 'Karl Foerster' is one of the earliest perennial grasses to emerge in spring. Its green summer flowers fade to buff. 

Grow Calamagrostis acutiflora 'Karl Foerster' in moist but well-drained soil, in groups in a mixed border, or en masse to form a large, dramatic screen. In early spring, cut it back to around 12cm to allow new growth to emerge.
