The blue flowers can be dried for use in winter arrangements. The plant usually grows near the sea shore so tolerates dry sandy soil and salt. Provide a sunny growing area for best color. Although tolerant of adverse sites, the plant grows well in good garden conditions. The plants are difficult to propagate.
Seed germination is erratic and division is difficult because of a long tap root.
If attempted, division should be done in early spring. This information is for educational purposes only.
