   I think it’s type of harmless fungus that grows in moist areas. Have you been spraying/misting the plant?

   It’s powdery mildew, a fungal disease. It will harm edible plants by deforming the crops like tomatoes and eventually kill the plants. Zinnias and peonies can become completely covered in it. It partially blocks the uv absorption interrupting the photosynthesis process. Treat with a commercial fungicide before it gets too widespread. Isolate the plant. Ensure there is adequate air flow around the plant. 🍀🪴
