Arabis scabra Bristol Rock-cress RRR DD N
This creamy-white crucifer has quite distinctive basal rosette of dark green leaves which appear to be both shiny and roughly hairy - so it doesn't look much like a typical Arabis. The plant doesn't usually have many flowers like A. caucasica for instance and the flower stalks (pedicels) are long. This dreadful photo was taken on a dark and rainy day so the stem is covered in raindrops.
