Growing Information
How to plant:

Propagate by seed, division or separation - Sow seeds in the late summer. The root system is tough, and makes division difficult, but not impossible.

Maintenance and care:
Plants may become leggy and require staking. Cut back the faded flower spikes to encourage secondary bloom.
