Expert Response

Thank you for your question, Aerin. I believe your plant has the following fungus: https://pnwhandbooks.org/plantdisease/host-disease/peony-paeonia-spp-leaf-blotch

If this is the disease, there are no fungicides available to homeowners. I suggest that you submit leaf samples to the OSU Plant Clinic for diagnosis: https://bpp.oregonstate.edu/how-submit-plant-materials

Good luck!
