Cut back flower stems after flowering has finished. Remove dead foliage as required

Propagate by division in early spring or early autumn. Propagate from seed (indoors or outdoors) in autumn or spring

May be attacked by aphids, slugs, snails, glasshouse red spider mite and thrips. This late-flowering species is less likely to suffer from Hemerocallis gall midge

Usually tough and reliable but may be affected by fungal leaf spot and rust diseases or bacterial leaf and stem rot
