Answer
Dear TomW, good morning. You have photographed a species of Cardamine (bitter-cress), members of the mustard family. From just the basal rosette I would not be able to tell you which species, but it looks most like plants of Cardamine impatiens (narrow-leaved bitter-cress) that I have seen (but it could be a related taxon). Best wishes.
