Herbaceous Peonies: Among shrubs, the most common ones I hear people wondering aloud about are hydrangeas, hydrangeas, and more hydrangeas. But when it comes to questions about perennials, herbaceous peonies top the list. To help us learn more about these extravagant, long-lived bloomers, I called peony expert Jeff Jabco of Scott Arboretum at Swarthmore College in Pennsylvania. Jeff is Director of Grounds and Coordinator of Horticulture there, and an officer of the Mid-Atlantic Peony Society.
Learn from Jeff when and how to plant them for best results; which varieties stand up to wind and rain best without toppling; how to have a peony season that extends to about seven weeks of beauty, and even when to cut flowers and prepare them to be longest-lasting in a vase (that answer may surprise you).
