Ensure good drainage to prevent root rot.
Deadhead spent flower stalks to encourage further blooming and prevent seed formation. Cut back the foliage to the ground in late autumn or early winter after it has yellowed and died back, tidying up the garden.
Seeds can be sown in autumn or early spring. Stratify seeds by refrigerating them for 4-6 weeks before sowing. Division of established clumps is best done in early spring before new growth emerges.
Use care as roots can be brittle.
This plant generally prefers to be left undisturbed once established. Repotting is rarely necessary.
If division is performed, use fresh, well-draining potting mix and choose a pot that is only slightly larger than the root ball.
