The common peony is a allotetraploid with two double sets of chromosomes from different parents (2n+2m=20), so it is a hybrid or nothospecies. One of the parents is most likely Paeonia peregrina. The other parent is one of the group of very closely related species, Paeonia parnassica, P. arietina and P. humilis. Both these parents are tetraploids themselves. Interestingly, P. officinalis has by far the most extensive range and is one of the more abundant species in the Mediterranean region.
The common peony is known from the South of France, through Switzerland to the Middle of Italy.
