The German name «Pfingstrose» (Pentecost Rose) comes from its flowering period around Pentecost.
The botanical name «Paeonia», on the other hand, goes back to the Greek physician Paeon,
who is said to have healed the wounded god of the dead Hades with the help of peonies.
With this, however, he enraged the god of medicine, Asclepius, who tried to kill Paeon out of jealousy.
But Zeus saved Paeon by transforming him into a beautiful peony.
