Silverweed (Argentia anserina or Potentilla anserina) is a low growing perennial plant that grows in places that are good for foraging like verges and waste ground. It likes sandy soil. Yellow flowers appear between June and August among the leaves which remain all year-round. It is not poisonous for rabbits but is not particularly palatable. It is a plant that might be picked with others but is not worth looking for.
