Calamagrostis Karl Foerster, also known as ‘Feather Reed Grass’ is a clump forming, perennial grass with long gracefully arching mid green leaves.  Amongst the tall erect stems, feathery, pinkish-purple flower plumes emerge from July through to August.  The seed heads become narrow and tan coloured as they mature towards the Autumn. A superb architectural plant for the perennial border, adding both structure and height, particularly effective when mass planted, waving in even the gentlest breezes.

Looking After Your Calamagrostis Acutiflora Karl Foerster

Generally pest and disease free, an easy to grow perennial grass in many if not all locations. This low maintenance, drought resistant grass will benefit from a sunny, or partially shaded area in all types of garden, from the informal cottage garden planting scheme to the more formal town/city or coastal garden. Calamagrostis will thrive in most soil conditions, preferring a free draining site away from any wet or water logged conditions. Cut hard back to ground level, late Winter or early Spring, when applying a good quality general purpose fertiliser will help promote fresh new growth.
