This delightful sea holly has long lasting flowers that arrive in mid- to late summer, turning bright metallic-blue as they age and usually lasting well into the autumn. They have a strong architectural shape, so are best in uncrowded borders where they can really stand out on their own. Honey bees love their flowers so they are perfect for adding to a sunny, wildlife-friendly garden.
