Keep the soil consistently moist during the growing season, but not waterlogged. Reduce watering significantly in winter when the plant is dormant.

Allow the top inch of soil to dry out slightly between waterings in warmer months. Ensure good drainage to prevent root rot.

Prune after flowering to remove spent flower stalks and any dead or damaged foliage. This helps maintain a tidy appearance and encourages healthy new growth. Minimal pruning is generally required for this species.

Propagate by division of rhizomes in spring. Carefully separate sections of the rhizome, ensuring each piece has at least one bud or shoot.

Plant the divisions in well-draining potting mix and water lightly until established.

Repot every 2-3 years or when the plant becomes root-bound, preferably in spring. Use a well-draining potting mix, such as a blend of peat moss, perlite, and compost.

Choose a pot only slightly larger than the previous one.
