Sedum acre
… is commonly called Biting Stonecrop or Wallpepper or Goldmoss Stonecrop. The leaves have a sharp taste, from which it gets its Latin name ‘acre’, meaning sharp. I tasted it recently for the first time and at first thought it was tasteless, then the sharp peppery taste developed and I was pleased to have a drink with me. Anyway, it is now in full bloom on the shingle, but this golden display will only last a week or so.
