Meaning from Greek Mythology. The legend and meaning of the peony goes all the way back to Greek mythology. It is believed that the peony is named for a person of healing named Paeon who was a student of Asclepius, the god of medicine and healing.
Tree Peonies-Starting from Seed. Another dark tree peony, but this one more open and called 'Kronos'. There is a whole series of tree peonies with Greek names. The next one is 'Wacedah Princess'. It is the creation of the late David Reath, one of the more prolific hybridizers.f you want to try planting peony seed, just wait until the seed cases crack, but before they drop the seed. You can also do your own hybridizing-putting pollen from one plant on another, but if you just want to try growing them, any old seed will do.
