“Peonies have been used as medicinal plants for at least two thousand years. The peony flower and root have been much coverted and held in high esteem; an ancient Greek poem referred to them as “the Queen of all herbs” and the ancient Chinese considered the “tree peony” to be the “King of flowers”.
It is thought to have been named after the Greek mythological figure, Paeon, a pupil of Asclepius, the Greek God of medicine and healing. ….. Peonies were highly valued as medicinal plants; their roots and seeds were used extensively in the treatment of a wide range of ailments. … Few herbaceous perennials have had the longevity that peonies enjoy,
as they can easily survive for over a hundred years.” (Peonies – Martin Page 1997)
The Chinese have a very old saying, which I am seeing play out as a truism in our own peony paddock:
“The first year they sleep; the second year they creep and the third year they leap.”
