Itoh Peony (Paeonia 'Caroline Constabel')

The Itoh Peony ‘Caroline Constabel’ doesn’t have a single “native region” in the same way a wild plant does. Here’s why:

* **Hybrid Origin:** Itoh Peonies are a hybrid between herbaceous (garden) peonies and tree peonies. This is a cross that doesn’t occur naturally in the wild. The Itoh hybrid was developed in Japan by Toichi Itoh.

* **Cultivar:** ‘Caroline Constabel’ is a specific cultivar (cultivated variety) of Itoh Peony. It was bred and selected for its particular flower characteristics, growth habit, etc. So, it’s a human-created plant.

* **Parent Species Origins:**
* **Herbaceous peonies (Paeonia lactiflora):** Native to central and eastern Asia, especially China, Siberia, and Japan.
* **Tree peonies (various Paeonia species):** Primarily native to China, with some species also found in Tibet and Japan.

**In summary:** While the *genetic ancestors* of ‘Caroline Constabel’ originate from China, Siberia, and Japan, the plant itself was bred and developed as a hybrid cultivar, meaning its “native region” is essentially the place where it was first created, likely Japan or another region with active peony breeding programs. Now, Itoh peonies are grown in gardens worldwide where the climate is suitable for peonies (USDA zones 4-9)
