1. The origin of the two

They both belong to Ranunculaceae and Paeonia, so they are bound to have many similarities, and it is even easy to make people confused. In fact, there is no difference between the two ancient plants. Later, the terms "wood peony" and "grass peony" appeared. After that, "wood peony" became what we now call peony; "Herbaceous peony" is what we now think of as peony. There are records about them in compendium of Materia Medica
