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
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
No pruning required, but old leaves and flower stems may be removed to improve appearance
May be susceptible to vine weevil, especially when grown in containers
Generally disease-free
