Water regularly, especially during dry periods, ensuring the soil dries slightly between waterings. Avoid overwatering, as this can lead to root rot.

Established plants are somewhat drought-tolerant, but consistent moisture promotes best growth and flowering. Reduce watering in winter.

Deadhead spent flowers regularly to encourage more blooms and prevent self-seeding. Lightly trim back plants after flowering to maintain a tidy shape and promote bushier growth.

Avoid heavy pruning, especially in late autumn, as it can reduce winter hardiness.

Easily propagated from seed sown in spring, either directly outdoors or started indoors a few weeks prior. Cuttings can also be taken in late spring or early summer and rooted in moist, well-draining soil or a sand/peat mixture.

Repot young plants annually in spring as they outgrow their containers. Mature plants can be repotted every 2-3 years or when root-bound.

Use a well-draining potting mix, and select a pot that is only slightly larger than the current one.
