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

Ensure good drainage to avoid waterlogging, especially in containers.

Prune only to remove dead, damaged, or diseased foliage after flowering. Deadheading spent blooms can encourage a tidier appearance and potentially a second, though often sparser, flowering.

Avoid heavy pruning, as this can disrupt the plant's natural form.

Propagate from seed sown in autumn or early spring. Seeds require a period of cold stratification. Alternatively, divide established clumps in early spring or autumn. Handle roots gently, as they can be brittle.

Sow seeds in well-draining soil.

Repot container-grown plants every 2-3 years in early spring before new growth starts. Use a well-draining compost mix, such as a blend for alpine or herbaceous plants.

Choose a pot that offers adequate space for root growth and ensures good drainage.
