Deadhead spent flowers regularly to encourage continuous blooming and maintain a tidy appearance. Light pruning can be done after flowering to shape the plant and remove any straggly growth. Avoid hard pruning.

Easily propagated from seed sown in spring or by taking softwood cuttings in late spring or early summer. Seeds can be sown in a seed tray and kept moist in a warm location.

Cuttings root readily in a moist, well-draining medium.

Repot young plants annually in spring to provide fresh soil and more space for root growth. Mature plants can be repotted every 2-3 years or when they become root-bound. Use a well-draining potting mix.
