They require a sunny or partial shade in well-drained soil. Plant Intersectional peonies so that the roots are covered up to where the branching begins.

This is an intersectional peony, which is a cross between a woody-stemmed tree peony and an herbaceous peony that dies back in autumn. The woody growth can be cut back during the winter.
