Seakale Lilywhite Seeds

€4.50

Crambe maritima

One of our favourite things to harvest in the garden each year and simply cook in plenty of salted butter. Lilywhite Seakale is a rare and beautiful perennial vegetable with deep roots in Ireland’s coastal food culture. Once common along shorelines and in kitchen gardens, sea kale was prized for its gently sweet, subtly nutty flavour and its quiet generosity, returning year after year.

Plants form crinkled blue-green leaves and airy clouds of delicate white flowers in summer. In early spring, tender shoots are traditionally produced by forcing the crowns under terracotta pots, yielding pale, blanched stems long considered a true delicacy and cooked much like asparagus.

Seakale needs a permanent spot in the garden, like rhubarb. It is slow to establish, but rewards patience with decades of harvests, resilience, and a strong sense of place.

Average number of seeds: 10

Open-pollinated, chemical-free seeds. Grown and saved in Wexford, Ireland. We only grow and save seeds from plants that were started from certified organic seeds.

Each seed packet includes growing tips and cooking suggestions inside.

  • Seakale is slow-growing but very long-lived, so choose its position carefully. Sow seeds in pots or deep modular trays using peat-free organic compost. We recommend soaking the seeds in a light chamomile tea for 24 hours before sowing to aid germination. Germination can be slow and uneven, so patience is key. Keep compost moist but not waterlogged.

    Grow plants on in pots for their first year, then plant out into a permanent position, spacing 75–90 cm apart, in well-drained soil enriched with compost or grit. Seakale prefers full sun and space and dislikes disturbance once established.

    Sow: March to May
    Plant out: Following spring or autumn
    Harvesting time: From year 2 onwards (early spring shoots)

    To harvest traditional blanched shoots, cover crowns in winter with terracotta forcing pots or buckets.

  • Seakale has a gently sweet, subtly nutty flavour that really shines when kept simple. We love the blanched spring shoots served with melted butter, extra virgin olive oil, or hollandaise, finished with lemon and a pinch of flaky sea salt.

    Young leaves can be lightly steamed or sautéed like spinach, while unopened flower buds are delicious cooked like tender broccoli. For the best flavour and texture, harvest shoots while young and pale.
