Water consistently during the growing season, allowing the soil to dry slightly between waterings. Reduce watering significantly in winter.

Ensure good drainage to prevent root rot, as this plant prefers drier conditions once established.

Prune lightly after flowering to deadhead spent blooms and maintain a tidy shape. For older plants, a more significant prune in early spring can rejuvenate growth. Remove any dead or damaged stems at any time.

Easily propagated from seeds sown in spring, either indoors or directly outdoors after the last frost. Cuttings can also be taken in late spring or early summer from non-flowering shoots.

Repot young plants annually or every two years in spring to provide fresh soil and more space. Established plants generally prefer to be slightly pot-bound and may not require frequent repotting.
