Calamagrostis Avalanche, commonly known as Feather Reed Grass, is a variegated form of Karl Foerster, and is a clump forming, deciduous perennial, with arching green leaves that have a distinctive, central, white stripe. During the summer months, greenish-mauve plumes, maturing to silvery-pink are formed on stiff, erect wheat coloured stems. This is a superb architectural plant for the border or gravel planting, giving structural height, and by leaving the foliage and flower plumes to dry naturally during the winter months, one can watch the wind gently swaying the delicate stems to and fro, thus making this grass a truly year round performer.
Looking After Your Calamagrostis Acutiflora Avalanche
Generally pest and disease free, this Calamagrostis is an easy to grow perennial grass in many, if not all locations. It is a low maintenance, drought resistant grass that will benefit from a sunny or partially shaded area in all types of garden, from informal cottage planting schemes to the more formal town/city garden, including coastal planting schemes. Calamagrostis will thrive in most soils, preferring free draining sites away from any wet conditions. Cut hard back to ground level early Spring, to allow for fresh new growth and apply a good quality general purpose fertiliser if necessary.
