Water consistently, especially during establishment and dry periods. Allow the top centimeter of soil to dry out between waterings. Good drainage is crucial to prevent root rot, as this plant dislikes soggy conditions.

Reduce watering in winter when growth slows.

Deadhead spent flowers to encourage reblooming and maintain a tidy appearance. After flowering, a light trim can help to keep the plant compact and prevent it from becoming leggy or spreading too aggressively.

Remove any dead or damaged foliage as needed.

Propagate by division in early spring or autumn. Carefully separate clumps of established plants, ensuring each section has roots and shoots.

Alternatively, seeds can be sown in autumn or spring, often requiring a period of cold stratification for germination.

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