The semidouble blooms are lavender and 8 inches across, sometimes showing yellow in the middle.
The Tree Peony is one of the most glorious shrubs known. The huge, silky flowers are similar to those of herbaceous Peonies, but are borne on woody plants that may reach 4-5 feet tall at maturity. (The "tree" in the name is overstating the size. These are exquisite shrubs.)
Tree Peonies grow best in full sun or partial shade (required in the South and warm areas of western Zone 9) and evenly moist but well-drained soil with a pH close to neutral. We ship 3-year-old, grafted, 12-18in bareroot plants. They take a year or two to show what they can do, but are more than worth the wait.
