Sea Campion could sometimes be confused with:

Campion, Bladder, Campion, White,

As its name might suggest, this perennial occurs mainly near the sea.  Growing to 20cm, mostly on shingle and cliffs from June to August, it has snow-white flowers (20-25mm across), with overlapping petals.  Its sepal-tube is inflated to form a bladder and carries a beautiful tracery of reddish markings. The flowers are borne in a loose cluster.  Sea Campion's grey-green leaves are slightly fleshy which helps it to retain moisture in the face of sea winds. This plant is a native and belongs to the Carophyllaceae family.

I first identified this flower on Rossadillisk, Co Galway in 1975 and photographed at Saltmills, Co Wexford in 2009.
