Key traits and growing stats from plant data
Watering, pruning, propagation, and repotting details from plant data
Keep the soil consistently moist but not waterlogged, especially during the growing season. Allow the surface to dry slightly between waterings.
Reduce watering in late autumn as the plant enters dormancy, but do not allow the soil to become bone dry.
Remove spent flowers and seed stalks after flowering to prevent the plant from expending energy on seed production. Trim away any dead or damaged foliage in late autumn before the onset of winter dormancy.
No other pruning is typically necessary.
Propagation is primarily achieved through division of established clumps in early autumn. Gently separate rhizomes, ensuring each piece has at least one bud.
Alternatively, seeds can be collected and sown in a cold frame, but germination is slow and erratic.
Repotting is infrequent and best done in early autumn when the plant is dormant. Choose a pot that allows ample room for the rhizome to spread.
Use a well-draining, woodland-style potting mix enriched with organic matter.
