Water regularly, keeping the soil consistently moist but not waterlogged. Allow the top 2-3 cm of soil to dry out between waterings, especially during hot weather. Reduce watering in cooler months to prevent root rot.

Ensure good drainage to avoid standing water.

Prune back after flowering to encourage a bushier habit and potentially a second bloom. Remove spent flower spikes regularly. Cut back hard in late winter or early spring to remove dead or weak stems and shape the plant.

This promotes vigorous new growth.

Propagate from semi-hardwood cuttings taken in summer or from seed sown in spring. Cuttings root readily in moist, well-draining soil or a seed-starting mix.

Seeds require stratification or a period of cold to germinate effectively.

Repot every 2-3 years in spring when the plant becomes root-bound. Use a good quality, well-draining potting mix. Choose a pot that is only slightly larger than the current one to avoid overwatering issues.

Water thoroughly after repotting.
