Expert Response
The peony and the hydrangea look like they may have herbicide damage to the leaves. I don't see any damage on the hostas. Have you or your neighbor sprayed herbicide recently (weed killer on the lawn)? Another possibility is the late cold freeze we had this spring. The plants started to leaf out, then froze in the heavy frost. Trim off the damaged plant leaves and/or branches.
