Peony bloom sequence


Below is a rough breakdown of the bloom times of the various types of peonies. During very warm springs this period is very compressed. We have listed here a few cultivars for each bloom period. In the cultivar descriptions for our tree, herbaceous and intersectional peonies on our website we list the bloom period.
