Intersectional Peony (Paeonia 'All That Jazz')

While Intersectional Peonies (also known as Itoh Peonies) like ‘All That Jazz’ are a hybrid, and therefore don’t have a single “native region” in the traditional sense, we can deduce their origins based on their parentage:

* **Herbaceous Peonies:** These are primarily native to Eurasia, including regions of China, Russia, and Europe.
* **Tree Peonies:** These are mainly native to China.

**Therefore, ‘All That Jazz’, being a hybrid between these two types, has its origins in the regions where both herbaceous and tree peonies are found, particularly China and Eurasia.**

It’s important to note that ‘All That Jazz’ itself was likely bred in a controlled environment, possibly in North America or Europe, and isn’t a naturally occurring plant in the wild. However, its genetic heritage points back to the peony species native to China and Eurasia.
