Water regularly, allowing the soil to dry slightly between waterings. Ensure good drainage to prevent waterlogged conditions, especially during cooler months. Reduce watering in winter when the plant is dormant.

Consistent moisture is key for healthy growth and flowering.

Prune after flowering to maintain a tidy shape and encourage bushier growth. Deadhead spent blooms regularly to promote continuous flowering and prevent self-seeding if unwanted.

Light pruning can also be done in early spring to remove any winter damage.

Easily propagated from seed sown in spring, either directly outdoors or in a protected seed tray. Cuttings can also be taken from semi-ripe shoots in summer and rooted in well-draining compost.

Division of established clumps in spring is another effective method.

Repot young plants annually or every two years in spring to refresh the soil and provide more space for root growth. Mature plants may only need repotting every few years.

Use a well-draining potting mix, such as a blend of peat and sand.
