Fertilizing

Balanced perennial feed every four weeks from spring through summer

Pruning

No pruning required, but old leaves and flower stems may be removed to improve appearance

Propagation

Propagate by division. Lift the plant once in spring growth, taking small vigorous sections from around the edge. Each section should have good roots and 2-3 shoots

Growing

Thrives in fertile, moist but well-drained soil in dappled or afternoon shade, or in full sun if the soil is reliably moist. Mulch annually, and divide every few years to prevent the rhizomes rising to the surface
