Water regularly during the growing season, ensuring the soil is consistently moist but not waterlogged. Reduce watering significantly in winter, allowing the soil to dry out between applications to prevent root rot.

Adequate drainage is crucial for this alpine species.

Deadhead spent flowers to encourage more blooms and prevent self-seeding if undesired. Trim back any leggy or untidy growth in late autumn or early spring to maintain a compact shape.

Remove any dead or diseased foliage promptly.

Propagate by division in early spring, separating clumps of established plants. Sow seeds outdoors in autumn or stratify them before sowing indoors in spring. Germination can be slow and erratic, requiring patience.

Repot container-grown plants every 2-3 years, or when root-bound. Use a well-draining, gritty compost mix. Repotting is best done in early spring before new growth begins, or in early autumn after flowering.
