Water moderately during the growing season, allowing the soil to dry out slightly between waterings. Reduce watering significantly in winter when the plant is dormant to prevent root rot.

Ensure good drainage to avoid waterlogged conditions, which this species dislikes.

Deadhead spent flower stalks to encourage further blooming and maintain a tidy appearance. Trim back any dead or damaged foliage in late autumn after flowering has finished. Pruning is generally minimal for this species.

Propagate from seeds sown in autumn or early spring. Germination can be slow and requires cool conditions.

Division of established clumps can also be done in autumn or early spring, ensuring each division has sufficient roots.

Repot young plants annually or as needed, usually in early spring before new growth begins. Mature plants can be left in their pots for several years.

Use a well-draining potting mix, such as a sandy loam, to ensure good aeration.
