Care guide
Plant in full sun in well-drained, preferably chalky soil. Sea Kale has a deep taproot and tolerates drought well. Avoid heavy, wet soils. Give the plant ample space — it can grow quite large. Transplanting is difficult due to the deep root.
Pruning tips
Cut flower stems after blooming — they become messy once flowers fade. The foliage remains attractive into autumn. The plant does not need dividing and lives long in the same spot.
