Did you know

  • Sea campion grows on some of the most inhospitable coastal habitats in Europe — cliff tops, shingle beaches, and sea walls battered by salt spray.
  • Its inflated, balloon-like calyx (the green bladder behind the petals) is distinctive and gives the family Caryophyllaceae (including carnations) a recognizable trait.
  • In the Scilly Isles, a rare subspecies called the Scilly campion (Silene uniflora ssp. scilloniensis) grows only on the island of St. Helen's.
  • The plant is one of the primary hosts for the rare and specialized moth Hadena irregularis, which lays eggs exclusively in campion flowers.
  • It forms low, dense, spreading mats that stabilize cliff-edge soils and provide nesting material for seabirds on rocky Atlantic coastlines.
