Water consistently during the growing season, keeping the soil evenly moist but not waterlogged. Reduce watering in autumn and winter, allowing the soil to dry out slightly between waterings.

Ensure good drainage to prevent root rot, especially in containers. Overwatering is a common mistake.

Prune after flowering to maintain shape and encourage bushier growth. Deadhead spent blooms to prevent seed formation and prolong the flowering period. Remove any dead, damaged, or crossing stems at any time of the year.

Light pruning can also be done in early spring.

Easily propagated from seeds sown in autumn or early spring. Division of established clumps in spring or autumn is another effective method.

Cuttings can also be taken in late spring or early summer, although this is less common for this species.

Repot container-grown plants every 2-3 years, preferably in spring before new growth begins. Choose a pot slightly larger than the current one and use a well-draining potting mix.

This helps to refresh the soil and provide adequate space for root development.
