I walked my gardens this morning specifically looking for mildewed peonies. 'Roselette' and 'White Innocence' seem to be the only ones out of 160 peonies. However, most of my peonies are starting to turn brown or blackish. It's actually time to trim them to the ground.
Note, I usually have several peonies that mildew. However, I have not kept a record of the ones that did.
