Keep the soil consistently moist but not waterlogged. Water thoroughly when the top inch of soil feels dry to the touch. Avoid letting the plant dry out completely, especially during active growth and flowering.

Reduce watering slightly during dormancy.

Deadhead spent flowers to encourage more blooms and prevent self-seeding if unwanted. Trim back the plant after flowering to maintain a tidy appearance and promote a healthy structure for the next growing season.

Remove any yellow or dead foliage.

Propagate primarily from seeds sown in autumn or early spring. Seeds may require a period of cold stratification.

Division of established clumps is also possible in spring or autumn, ensuring each division has roots and shoots.

Repot every 2-3 years or when the plant becomes root-bound. Use a well-draining potting mix. Repotting is best done in early spring before new growth emerges or in autumn after flowering.

Ensure the new pot is only slightly larger than the previous one.
