Lysimachia punctata

Better known as the dotted loosestrife, large yellow loosestrife, circle flower, or spotted loosestrife. Called Punktierte Gilbweiderich here.
We brought them to our garden some years ago, from the garden of my in laws. Since then they felt "at home" and we see them at several places in our garden.
