In August the golden samphire (Inula crithmoides) starts coming in to flower and is especially well established on the cliffs at Durslton; although it can be found on shingle banks and drier areas of salt marsh too.
Golden samphire is a member of the daisy family and is unrelated to rock samphire which is a carrot. It has an entirely different flower to rock samphire but has similar slender, fleshy leaves which is why I guess both share the English name of samphire. The scientific names have a resemblance too with rock samphire being 'crithmum' and golden samphire being 'crithmoides' or 'crith like' however crith seems to mean to tremble, shake or shiver so I am not sure what he connection is..
Flowering from late July until early September the golden daisy flowers cannot be missed nor can they really be mistaken for anything else.
