Water moderately during the growing season, allowing the soil to dry out slightly between waterings. Reduce watering significantly in winter, providing just enough to prevent the soil from becoming bone dry.

Overwatering can lead to root rot, especially in cooler temperatures.

Deadhead spent flowers regularly to encourage more blooms and maintain a tidy appearance. Trim back any leggy or overgrown stems in late autumn after flowering has finished.

This helps to shape the plant and prepare it for winter dormancy.

Easily propagated from seeds sown in spring, either directly outdoors or in a seed tray. Cuttings can also be taken from non-flowering shoots in late spring or early summer. Root cuttings in well-draining compost.

Division of established clumps is also an option in early spring.

Repot young plants annually in spring as needed. Mature plants can be left in their pots for 2-3 years.

Use a well-draining compost mix, such as a standard potting mix with added grit or perlite, to ensure good aeration and prevent waterlogging.
