The bright cerise-red ball of serrated petals forms a neat dome backed by larger guard petals. These are carried on tall stems. There seems to be two types going around under this name. I trust this is the double form!
Peonies will grow in most soils as long as they are not wet, including clay soils. They require a sunny or partially shaded site. Herbaceous peonies need to be planted with the eye (the dormant pink buds) no more than 2.5cm below the surface of the soil. Do not mix manure in the soil before planting as this may rot the eyes.
