Paeonia × suffruticosa is a name used for a group of cultivars of tree peonies that are the result of hybridisation with species exclusively belonging to the subsection Vaginatae. Paeonia suffruticosa, also known as the tree peony, originates from China. Sometimes, people refer to these tree peonies as “Chinese tree peonies.” Paeonia suffruticosa belongs to the peony family. The most distinctive feature is that Paeonia suffruticosa is a bush or a tree, whereas most peonies are herbaceous. Despite their classification as trees, it is the flowers that attract people's attention.
