Description: This species is not native to Ireland and is a fairly recent arrival, mostly within the last 60 years. It is now frequent on stone walls, sometimes growing in dense masses along long stretches of wall (e.g. along the Antrim Coast Road). It has fleshy leaves, like all stonecrops, and a rather large head of white star-shaped flowers.
