Crambe maritima (Sea Kale) is a robust herbaceous perennial forming a fantastic clump of large, lobed, wavy-edged powdery-blue leaves. Resembling cabbage leaves, they form a bold foliage mound that is handsome in its own right. In summer, dense sprays of small, fragrant creamy-white flowers are carried above the foliage. Aside from being ornamental, Sea kale is also a popular vegetable in parts of Europe, where shoots are blanched in the spring and eaten like asparagus. It is also useful in coastal areas where salt spray and saline soils are common.
