Keep the soil consistently moist, but avoid waterlogging. Water thoroughly when the top inch of soil feels dry. During hot, dry periods, ensure more frequent watering.

Reduce watering in cooler months if the plant is not actively growing.

Pruning is minimal. Deadhead spent flowers to encourage further blooming and maintain a tidy appearance.

If the plant becomes overgrown or leggy, a light trim in late spring or early summer can help rejuvenate it and promote bushier growth.

Propagation is easily achieved by division of established clumps in early spring or autumn. Seed can also be sown outdoors in autumn or early spring.

Alternatively, softwood cuttings can be taken in late spring and rooted in moist soil.

Repot young plants annually or as needed in spring. Mature plants can be repotted every 2-3 years or when they outgrow their containers. Use a well-draining potting mix.

Ensure the new pot is only slightly larger than the current one.
