Sea Campion or Bladder Campion is a perennial small herb. The leaves, which grow in a mat on the ground, are opposite, narrow, grey-green and waxy up to 20 mm tall. The flowers can be seen from June to August and are pure white with 5 petals.

This perennial plant can be recognised by a pink/brown “balloon” behind the petals and can be seen on rocky shores, cliffs and, sometimes, on mountains.

Its botanic name is Silene uniflora, in Irish it is called Coirean mara.
