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 rhizome cuttings or division of established plants in spring

Suggested planting locations and garden types

Architectural
Cottage and informal garden
Hedging and screens

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
