Raspberry (Rubus idaeus 'Joan J')

The raspberry cultivar ‘Joan J’ (Rubus idaeus ‘Joan J’) is a modern variety developed in the UK. However, the **native region of the species *Rubus idaeus* (the European Red Raspberry) is Eurasia**.

Therefore, while ‘Joan J’ was bred in the UK, its genetic ancestry traces back to wild raspberry populations in:

* **Europe:** Widespread throughout most of Europe.
* **Asia:** Parts of Asia, particularly temperate regions.

So, the plant’s ancestors are native to Eurasia, but ‘Joan J’ itself originated in the UK.
