Water moderately during the growing season, allowing the soil to dry out slightly between waterings. Reduce watering significantly in winter, especially if grown in cooler conditions.

Avoid waterlogging, which can lead to root rot. Ensure good drainage.

Prune to maintain shape and encourage bushier growth. Deadhead spent flowers regularly to prolong blooming and prevent self-seeding. In early spring, cut back any dead or overgrown stems to stimulate new growth.

Light pruning can be done anytime.

Easily propagated from seed, which can be sown directly into the garden in spring or autumn. Can also be propagated by cuttings taken in late spring or early summer.

Seeds germinate readily and may require stratification in some climates.

Repot young plants annually or as needed when root-bound. Mature plants generally do not require frequent repotting and can be grown in containers or in the ground. Use a well-draining potting mix when repotting.
