How to grow

Cultivation Grow in moderately fertile, moist but well-drained or damp soil in partial shade, or full sun where soil stays damp in spring and summer. Usually clump-forming but creeping rootstock can become invasive in warm, moist or favourable conditions and need restraining ; see bamboo control and bamboo cultivation

Propagation Propagate by young rhizome cuttings and the division of established plants in Spring

Suggested planting locations and garden types Architectural Patio & Container Plants

How to care

Pruning Remove weak, dead, damaged or spindly stems in spring and thin to show off stems to best effect. Cut out any flowering shoots promptly to discourage more from forming - see bamboo cultivation

Pests Slugs may damage new shoots

Diseases Generally disease free
