Is this powdery mildew? This is a close up of pulmonaria "Mrs. Moon". I have never had powdery mildew before and have never grown this plant before. Don't know if Mrs. Moon is supposed to look like this or not. She didn't look like this when I planted her. We have also had tons of rain in the past week.... 5" this week alone. If this is powdery mildew, how do I treat it? Appreciate any help. Thanks,
