Sea Holly features open umbels of prickly steel-blue flowers, which are a favourite for cutting, fresh or dried. This strain flowers reliably even in the first year, producing large open heads with exceptionally good blue colour. In time plants will spread to form a small patch. Easily divided in early spring. Tolerant of hot, dry sites, and soils high in salts. For drying, pick stems just as the flower clusters open fully, and hang upside down to dry in a warm, dark place. Attractive to butterflies.
