Karl Rosenfield Peony rugged-square-succulent-pot Centaurea also known as CornflowerPeonies bloom best in well drained soils in full sun but tolerant some shade as long as they have at least a half day of sunshine. Good air circulation around the plant is important. Space 2 4 feet apart depending on desired effect. Never plant peonies back in the same location until you have removed soil that was around the original plant and replaced with new soil. We suggest that you work the soil 18 inches deep, into a good loose condition.
