Preliminary Report on the Introduction of Intersectional Hybrids between Tree and Herbaceous Peonies

Thirteen intersedional hybrids of herbaceous peony x tree peony were successfully introduced to Beijing from America. Observation on their phenophase and main characters showed that the hybrids adapted themselves well to the climate of Beijing with no signs of diseases or insect pests. Almost all of the varieties can blossom while maintaining a comparatively high appreciating value, which demonslrates the advantages peculiar to intersectional hybrids. They have a growing propensity similar to tree peonies and an appearance like that of herbaceous peonies. Sharing the common characteristics and advantages of both tree and herbaceous peonies, they display an elegant stem, a refined canopy of exuberantly emerald leaves and mainly yellow blossoms of high quality. Their florescence goes between that of tree peonies and herbaceous peonies. Therefore, they are worthy to be popularized in landscape.
