Watering, pruning, propagation, and repotting details from plant data
Water consistently during the growing season, allowing the soil to dry slightly between waterings. Reduce watering in fall and winter when the plant is dormant. Ensure good drainage to prevent root rot.
Prune after flowering to maintain a tidy appearance and prevent excessive self-seeding. Deadhead spent blooms to encourage reblooming. Cut back foliage in late fall or early spring before new growth emerges.
Easily propagated by seed sown in autumn or early spring. Seeds may benefit from scarification or a period of cold stratification. Division of established clumps in early spring is also an effective method.
Repotting is generally not necessary for established plants as they prefer to be undisturbed. If division is performed, repot the divisions into well-draining soil. Young plants may require repotting every 1-2 years.
