Sea-kale
Crambe maritima
Sea-kale is a striking coastal perennial with bold blue-green foliage and fragrant white flower clusters that pollinators adore. Plant it in full sun to partial shade in sandy, well-drained soil — it is highly tolerant of salt spray and coastal winds once established. The young shoots are edible and were historically blanched as a springtime vegetable, adding heritage appeal to the kitchen garden.
