Full sun is non-negotiable. A peony planted in the shade is a peony that throws a botanical tantrum—fewer flowers, taller stems, and a general sulk. Aim for at least 6 to 8 hours of direct sunlight each day. The only exception? In scorching zone 8 climates, give them a little afternoon shade to prevent the blooms from frying like an egg.
A fun fact from Chinese culture: the peony is called “the flower of riches and honor.” So, if you want good financial feng shui, put them in a sunny spot near the front of your house. Make your peonies happy, and they might just bring you prosperity—or at least great curb appeal.
