Black Tornado, Cup of Shining Night Peony Zone 8 approved. Protect against very hot summer afternoon sun. Morning sun and afternoon shade is ideal. If this is not possible, than plant peonies near a large shrub so that they are afforded a little protection from the very hot sun.In spring and summer, at least two deep waterings a week with supplemental drinks in between as necessary. This is doubly important for newly planted peonies.
