Water
Keep the soil consistently moist during the growing season, but allow it to dry slightly between waterings. Reduce watering significantly in late summer and fall as the plant goes dormant.
Avoid waterlogging, which can lead to root rot.

Watering, pruning, propagation, and repotting details from plant data
Keep the soil consistently moist during the growing season, but allow it to dry slightly between waterings. Reduce watering significantly in late summer and fall as the plant goes dormant.
Avoid waterlogging, which can lead to root rot.
Remove spent flower stalks after blooming to tidy the plant and prevent self-seeding if not desired. Trim back any dead or damaged foliage in late fall or early spring before new growth emerges.
Minimal pruning is typically needed.
Propagate from seed sown in autumn, mimicking natural conditions. Division of established clumps in early spring or after flowering is also successful.
Ensure new divisions have adequate moisture and are planted at the correct depth.
Repot young plants annually or as needed to ensure they are not pot-bound. Mature plants are best left undisturbed in their naturalized settings.
Repot in early spring before active growth begins, using a light, well-draining potting mix.
