Hi, Lindsey:
Is your plant in the ground or in a pot? If in a pot, how large? Is it in full or part sun? Against a brick wall or patio?
I see you're in Ohio--here as your next-door neighbor in Indiana, we've had a ton of rain which has had a really devastating effect on many plants.
Sorry for all of the questions, but any additional information you can provide will help the experts here try to diagnose the problem. Hope we can help you out!
Linda
