Keep the soil consistently moist but not waterlogged. Water thoroughly when the top 2-3 cm of soil feels dry. Reduce watering in winter, allowing the soil to dry out slightly more between waterings.

Avoid letting the plant sit in standing water, as this can lead to root rot.

Prune to maintain shape and encourage bushier growth. Remove any dead, damaged, or leggy stems as needed.

Light pruning can be done anytime, but heavier pruning is best done in late spring or early summer after flowering has finished. This helps prevent self-seeding if unwanted.

Easily propagated from seed sown in situ in spring or early autumn. It can also be propagated by division of established clumps in spring. Seeds require light for germination and may benefit from stratification.

Division is a reliable method for maintaining parent plant characteristics.

Repot in spring when the plant becomes root-bound, typically every 2-3 years. Choose a pot that is slightly larger than the current one. Use a well-draining potting mix.

Gently loosen the roots before repotting and water thoroughly afterwards to help the plant settle.
