I'm sad to say, but it seems like there's something wrong with one of my peonies. It has light brown splotches on its leaves. We had a stretch of extremely wet weather followed by some significant heat (around 100 degrees), so maybe that's the cause of it. I'm hoping someone can help me ID the issue and suggest some solutions. This peony is surrounded by a lot of other peonies, so if it's a contagious disease I need to nip it in the bud.
Attached are some photos. Thanks so much for the help!
I can't grow peonies here, and I don't know anything about them, but it looks like sunburn damage to me. My hydrangeas have the same thing from a hot spell we had a month ago.
It could be the sun and rain you had that has caused this browning on the foliage, but it could also be peony blight, so to be sure, remove these brown leaves by cutting them off at the leaf Axel, them burn them, if you dont see it on any other plants close to this, then it probably was the sun/rain, but your plant wont thank you for stressing it by leaving dead or withered leaves on it, there is still time for it to recover, keep a close eye on your other ones for the same symtoms so you can cut and destroy any other diseases leaves if they should show up, good luck.

Glad to help, hope it all works out, your peonies will have formed their flower buds by now, so removing some foliage wont harm them in any way, hope you have a wonderful show of blooms, WeeNel.
