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.
How to grow
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.
