Detailed Information

Geranium ‘Rozanne’ is a hybrid cultivar, so it doesn’t have a single “native region” in the same way a naturally occurring species does. It’s a cross between two Geranium species:

* **Geranium wallichianum:** Native to the Himalayas, specifically the Kashmir region.
* **Geranium himalayense:** Also native to the Himalayas and surrounding regions of Asia.

Therefore, while ‘Rozanne’ itself originated in the UK, its genetic heritage points to the **Himalayan region of Asia** as the geographical area where its parent species are native. Specifically, Kashmir and surrounding mountainous areas.

Suitable in 3 gallon or larger, Needs excellent drainage in pots
