Eryngium amethystinum


Sea Holly

USDA Zone: 2-9

Plant number: 1.205.100


Amethyst Sea Holly features open umbels of prickly steel-blue flowers, which are a favourite for cutting, fresh or dried. This is a very hardy species, small flowered but with superb colour in the garden, especially nice contrasting with yellow or gold neighbours. Compact in size, this may be useful towards the border edge. Plants 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.
