Calamagrostis 'Karl Foerster'
Popular with garden designers, this tall-growing upright grass brings a strong vertical accent to the perennial garden. Plant in groups of 3 or 4 for maximum impact. Flowering from early summer, enjoy the seasonal changes as the flower panicles age from bronze to beige in late autumn.
Tolerates most soil types but thrives in a moist, humus rich, well drained soil. Cut back to the ground in late winter to maintain compact clumps. Water as required during summer to improve flowering.
