Greenish in colour when young, but becoming purple-red as it matures, and is very resistant to drying out and the action of the waves. It forms thin, delicate sheets which cling to rocks and has a polythene-like texture. Width 20cm.
Found attached to rocks in sandy habitats. Abundant and widespread on rocky shores throughout.
Purple Laver is used to make laverbread in Wales, which is a traditional Welsh recipe.
