Intersectional Peonies extend the peony bloom, flowering alongside mid- to late-blooming herbaceous peonies. Not all the buds open at once. Instead, they tend to have 2 or 3 flushes of flowers, with waves of bloom that last for 2 to 3 weeks. It is not uncommon to have a seed pod forming on a plant that still has buds waiting to open. These plants are not fertile, and therefore will not produce viable seeds. They provide the much-loved yellow color that is rare in herbaceous peonies. Kathleen’s favorite is Don Hollinsworth’s creation, the Garden Treasure cultivar.

Note this is our best guess for the timing of the bloom. Warm weather will speed it up, cool with extend it, rain and wind can change it overnight, and a sunny day can make everything pop. Some days will have thousands of flowers in bloom and others will not.
