Armeria

Common name: Thrift · Sea pinks · Sea thrift

Armeria is a genus of evergreen, cushion-forming perennials in the plumbago family, native mainly to the coasts and mountains of Europe and the Mediterranean, with some species in the Americas. Plants form dense tufts of narrow, grass-like leaves and send up wiry stems topped by globular heads of pink, white, or red flowers from spring into summer. Tough, salt- and drought-tolerant, they are grown as edging, rock garden, and seaside plants, and do well in containers.

Fun facts

  • Armeria maritima is the official flower of the Faroe Islands.
  • The common name thrift is said to come from the plant's ability to thrive in poor, salty soil where little else grows.
  • Sea thrift often colonizes coastal cliffs and salt marshes and tolerates direct salt spray.
  • Its dense cushions were once used to edge the cliffs and turf of traditional cottage gardens.
