It is an Inula Kerry. Not sure if it is Inula magnifica or Inula Royleana, but whatever it is, it is great. There was a huge clump at our previous cottage by the greenhouse, and when we moved I couldn't stand to leave it behind, so out came a lump, and now it is in my new garden and in my gramps garden in Devon. Seems to be good and tough and is like a ray of sunshine year after year after year after year...............
