Paeonia × suffruticosa is the name used for most tree peony cultivars, but is not a naturally occurring species. So it can be regarded as the name for a man-made hybrid swarm. Genetic analysis has shown that five species of the Paeonia subsection Vaginatae together make up the parentage of the tree peony cultivars created before World War II.
