Thanks, Luis! - I'll bet that's what it is as your link describes mis-shapeness (which I'd never seen with the powdery mildew on my lungwort), and also says that larkspur are particulary susceptible. I'm still wondering, though if it would be best to remove them before they infect other plants, or to try to treat them. They're in pretty bad shape. Does anyone have any thoughts about this?
