Watering, pruning, propagation, and repotting details from plant data

Deadhead spent flowers to encourage more blooms and prevent seed formation. Remove any dead or damaged foliage at any time of year. Minimal pruning is generally required; focus on maintaining a tidy appearance.
Best propagated from seed sown in autumn or early spring. Stratification (cold treatment) may improve germination.
Division of established clumps in early spring is also possible, ensuring each division has roots and shoots.
Repot young plants annually in spring as needed. Mature plants are best left undisturbed and can be repotted every 2-3 years. Use a well-draining potting mix, preferably amended with grit or perlite.
