Crambe maritima — Overblijvende Kustplant
Sea kale is one of Ireland's most spectacular native edible plants — a dramatic perennial with blue-grey leaves that grows wild on shingle beaches around the coast. The blanched spring shoots, forced under a pot or bucket, produce a delicacy that was served in the finest Georgian and Victorian dining rooms.
The flavour is somewhere between asparagus and hazelnuts, with a cabbage-family earthiness. Plants live for 20+ years and are completely hardy. The white flower heads in summer attract pollinators.
Sea kale needs patience — it takes 2–3 years to establish before you can start harvesting. But once established, a single plant will produce forced shoots every spring for decades.

Zaai-instructies
Soak seeds in warm water for 24 hours before sowing. Sow autumn (September–November) outdoors — needs cold stratification. Or sow in spring after 6 weeks in the fridge. Plant out 60cm apart in well-drained, sandy soil. Harvest forced shoots from year 3. Cover crowns with a bucket in February to blanch.
