Can a peony get too much sun?
Peonies like full sun, and though they can manage with half a day, they bloom best in a sunny spot that gets 6 to 8 hours of sunlight each day. Provide shelter from strong winds, as peonies' large blooms can make them top heavy. (Use stakes to hold them up, if necessary.)
