Looks like seed saving is a must, and cuttings. Great to see they seed freely. In Michigan 6A not many of mine reseeded so I will be more diligent in saving the seeds.

They seem to love reseeding in my potted plants' potting soil. Maybe try crumbling the flower heads in a pot or pots of potting soil at the end of the year. They would take over every pot I have if I let them.
