Keep soil consistently moist but not waterlogged during the growing season. Reduce watering in late summer and autumn as the plant begins to go dormant. Ensure good drainage to prevent root rot.

Water at the base of the plant to avoid wetting foliage.

Deadhead spent flowers to encourage further blooming and prevent self-seeding if desired. After flowering, the foliage can be tidied up or removed once it yellows and dies back naturally.

Avoid cutting back green foliage prematurely.

Best propagated by seed sown fresh in autumn, or by division in early spring or autumn. Seeds may require a period of cold stratification. Division should be done carefully, ensuring each division has roots and shoots.

Young plants may benefit from repotting every 1-2 years into slightly larger containers to accommodate root growth. Mature plants are best left undisturbed in their preferred locations once established, as they dislike being moved.
