Sea Kale

Crambe maritima

Once cultivated as a vegetable, wild Sea Kale now represents relatively undisturbed shingle habitats. Its bluish-green leaves and clusters of white flowers attract pollinators and stabilise shifting substrates. On Lihou’s shingle banks, these statuesque plants help preserve biodiversity while withstanding strong salt-laden winds.

  • Habitat: Shingle beaches, upper shorelines, and coastal banks.
  • When to See: Leaves and flower clusters visible from spring onward; white flowers in early summer.
  • Length: Large, waxy leaves can spread ~60–90 cm wide; flower stems can reach ~1 m.
