A terrific selection of Sea Holly, producing especially large heads of steel-blue prickly flowers over a mound of silvery leaves that add texture to the sunny border. Exceptionally good for cutting, fresh or dried. Plants are midsized in habit with strong stems. A versatile plant, fitting well into the border and also useful in containers. Drought tolerant once established. Sea Holly is an easy-care perennial that adapts well to most sunny areas with average to dry soil. Remove old stems to ground level in late fall or early spring. Rated to Zone 4 but likely much hardier and worth a try in Zones 2 and 3.
