Astilbe 'Fanal'

Astilbe ‘Fanal’ is a cultivar of Astilbe, and Astilbe species are native to **Asia and North America**. Specifically:

* **East Asia** is the primary source for most of the Astilbe varieties we see in gardens, including those from China, Japan, and Korea. These are the most likely ancestors of ‘Fanal’.
* A few species originate from **North America**.

Since ‘Fanal’ is a cultivated variety, it’s unlikely to have a single, specific native location. It’s bred from various Astilbe species. However, considering its characteristics, it is most likely to have origins from the East Asian species of Astilbe.

So, the most accurate answer is **East Asia**, with possible genetic contributions from other regions where Astilbe grows natively.
