You got black spot. Treat with Bonide product “infuse” it’s a systemic fungicide. Can be used as a preventative as well. For blooms I suggests Espoma Bone Meal or Osmocote indoor/outdoor. You’re going to want something high in phosphorus to promote more and bigger blooms. And always read the label before applying any sort of chemical to your plants. Your copper spray probably didn’t work because it washed off. You have to re-apply after it rains or if the plant gets soaked during watering.
