Caroline Constabel is a midseason Itoh (intersectional) peony carrying semi-double blooms in pink/pastel. Roots are field-grown in the Netherlands and arrive dormant and bare-root for fall planting.
Root size matters more than anything else on this page. An eye is a growth bud on the crown, and the eye count is what separates a root that flowers in its second season from one that sulks for four. Each root here is a three to five eye division, a full grade larger than the two to three eye roots most mail-order suppliers ship. Bigger roots carry more stored energy, establish faster, and give you more stems sooner.
Itoh peonies cross a tree peony with a herbaceous one. They keep the large flowers and strong stems of the tree peony while dying back to the ground each winter like a garden peony, so they need no staking and no winter protection once established.
Planting: full sun, well-drained soil, with the eyes set 1 to 2 inches below the soil surface. Planting deeper than that is the most common reason a peony never blooms. Space plants 3 feet apart. Hardy roughly in zones 3 to 8; a mature clump lives for decades and resents being moved.
First season: expect leaves and few or no flowers in year one. Peonies bloom properly from the second or third season onward.
