Sea Kale (Crambe maritima) is a stunning perennial vegetable that combines beauty and utility. Native to the coastal regions of Europe, this hardy plant produces striking, blue-green leaves and clusters of delicate white flowers. With a unique, slightly nutty flavor, sea kale is a gourmet favorite in the kitchen and an eye-catching addition to any garden.

Propagation from Seed

• Start Indoors or Direct Sow: Sow seeds in autumn or early spring. A period of cold stratification improves germination.
• Transplant Outdoors: Once seedlings are strong, transplant to a sunny spot with well-drained soil.
• Establishment: Sea kale can take a couple of seasons to fully establish, but it rewards with years of harvests!

Culinary Uses

• Sea kale is prized for its tender, asparagus-like shoots and edible leaves. Blanch young shoots for a delicious spring vegetable or enjoy leaves raw or cooked. In Victorian times, it was a popular delicacy in Britain’s finest kitchens!
