Water moderately, allowing the soil to dry out slightly between waterings. Avoid waterlogging, especially in winter. Established plants are drought-tolerant. Ensure good drainage to prevent root rot.

Prune after flowering to maintain shape and encourage denser growth. Remove spent flower stalks to prevent self-seeding if undesired. Light trimming can also be done to manage size.

Propagate from seed sown in autumn or early spring. Softwood cuttings can be taken in late spring or early summer. Division of established clumps is also an effective method.

Repot young plants annually in spring as needed. Mature plants generally do not require frequent repotting. Ensure the new pot has ample drainage holes.
