How to propagate woody peonies?
Crown division, the traditional method of propagating all, but the woody peony types, works well with the Itoh Group sorts. During a propagation cycle (3 to 4 years), the underground stem (crown) extends somewhat with tuberous growth and swells with food storage similar in habit to the Lactiflora parent type, facilitating the process of division. Tuberous food storage roots will similarly extend outward and downward, but will have a hard core, like the tree peonies. After a three or four year cycle, well grown plants will yield a comparable increase. The tuberous roots are of smaller diameter and longer than the common peony parent and somewhat less so than the woody peony parent. Adjust the length of tuberous root on individual divisions to retain an approximately equal amount of food storage for support of first year growth.
What is the Itoh group?
The Ito h Group cultivars (cultivated varieties, cvs.) make up the most recently hybridized peony type to reach the ornamentals market place in quantity. These innovations are produced by crossing the Lutea Hybrid tree peonies (woody stemmed) with the long grown common herbaceous peonies, the Lactiflora cvs. Historically, attempts to succeed with this cross were for long met by failure.
