Deadhead spent flower stalks to encourage further blooming and prevent self-seeding if unwanted. Remove any yellowing or dead foliage as needed to maintain plant health and appearance. Pruning is generally minimal.
Propagate by seed sown in autumn or early spring in well-drained soil. Division of established clumps in early spring is also an effective method. Seeds may require stratification for improved germination.
Repot young plants annually or every two years in early spring. Mature plants in the ground generally do not require repotting. Ensure the new pot has adequate drainage holes and use a well-draining potting mix.
