Seed heads are an attractive feature through the autumn. Useful cut flower. Popular in prairie style planting.

Cut down in late autumn or winter.
Best planted in the spring to avoid winter wet.
Generally free from pests and diseases, although slugs may attack new growth. Can rot off in the winter on wet, heavy soils.
