Planting
Choose full sun for the best display, or partial shade, in soil that does not stay soggy. Allow room for the clump to spread by underground stems.
Care
Leave seed heads for birds through winter. Divide in spring or autumn when you want more plants or need to manage a growing clump; heavy flower heads may need staking.
