While the cultivated variety ‘Hardy White’ has improved cold tolerance, the *species* *Nerium oleander* is native to the **Mediterranean region and parts of Asia**.
Therefore, even though ‘Hardy White’ can survive in slightly colder climates, its genetic lineage and ideal growing conditions still point back to a **Mediterranean-like climate**:
* **Warm, dry summers:** Oleanders thrive in heat and tolerate drought well once established.
* **Mild, wet winters:** They prefer not to freeze, although ‘Hardy White’ is more resilient.
* **Well-draining soil:** They don’t like to sit in soggy soil.
So, while you might find ‘Hardy White’ growing successfully in a broader range of locations thanks to its breeding, its origins are firmly rooted in the **Mediterranean and Asian regions with similar climates**.
