This wildflower, like the other Sea-spurreys, favours saltmarshes and shingly coastal habitats. Growing to a height of 40cm at most, it is a fleshy perennial with pale pink-mauve 5-petalled flowers (7-12mm across) which have white centres and 10 stamens (unlike Lesser Sea-Spurrey which has only up to 7). It also differs in that in Greater Sea-spurrey, the sepals are usually shorter than the petals. The plant blooms from June to September. The leaves are opposite and linear with short points. This is a native plant and it belongs to the Caryophyllaceae family.
I first found this plant growing in Ballyvaughan, Co Clare in 2007 and photographed it there at that time.
