How to grow

Cultivation Grow in fertile, humus-rich, moist but well-drained soil, in full sun or partial shade. Protect from cold drying winds. In a container grow in a loam-based compost and feed with a balanced liquid fertiliser on a monthly basis during the growing season. May remain clump-forming in poor or dry soils but can become invasive in warm, moist or favourable conditions; see bamboo control and bamboo cultivation

Propagation Propagate by division in spring
