Sea Holly features a summer bloom of steel-blue, thistle-like flower heads. This whimsical blue bloom is excellent as a cut flower or dried in arrangements and will thrive in dry, poor soils in full sun.  Avoid planting in moist, fertile soils where it will sprawl and may require support. 
Start Indoors 10-16 weeks before last frost. Surface sow with no cover. Bottom water or mist. Transplant outside after last frost. Require a period of cold, moist stratification to germinate.
