Contrary to most advice, I found the common peonies appreciate some light shade instead of full sun all day long. The red blossoms do not fade and dry as quickly. They seem to bloom a little later which protects them from late frosts. The foliage remains green later into into early October. Most peonies in this area are planted on the east side of houses. I have some in full sun and can really see a difference. As far as drainage is concerned, raised beds work well if the normal soil is generally damp or wet clay.
