Another coastal plant growing on a headland near Caerfai Farm. This was taken late on our last day. That night a cold front blew in and changed things utterly: high winds and torrential rain.
This is Rock Samphire, Crithmum maritimum, which is an unusual member of the Umbellifer family in that it has fleshy stems and leaves, like cacti. It is confined, as the binomial suggests, to coastal locations. Oddly it isn't found between the very north of Scotland and Suffolk.
