Lemon Tree (Citrus x limon 'Eureka')
The ‘Eureka’ lemon tree, like most lemon varieties, does *not* have a single, easily pinpointed “native” region. Here’s why:
* **Hybrid Origin:** Lemons are hybrids, meaning they are a cross between other citrus species. The exact parentage is debated, but generally includes citron (Citrus medica) and sour orange (Citrus × aurantium). So, it’s a mix of geographical influences.
* **Southeast Asian Ancestry:** The ancestral citrus species that contributed to the lemon’s development originated in Southeast Asia (specifically regions around India, Burma, and Southern China). The wild Citrus medica (citron) is believed to be from this region.
* **Mediterranean Development:** While the *ancestors* are from Southeast Asia, the *lemon itself* likely emerged in the Mediterranean region, possibly in Italy or North Africa. This is where extensive citrus cultivation and hybridization took place historically.
* **’Eureka’ is a Cultivar:** The specific cultivar ‘Eureka’ was developed in Los Angeles, California, in the 1850s. It’s a selected variety, not a naturally occurring species.
**Therefore, the most accurate answer is a combination:**
* **Ancestral Origins:** Southeast Asia (India, Burma, Southern China) for the wild citrus species that contributed to its genetic makeup.
* **Probable Development:** The Mediterranean region (Italy, North Africa) as the likely birthplace of the lemon through hybridization.
* **’Eureka’ Cultivar Origin:** Los Angeles, California.
While you won’t find ‘Eureka’ lemons naturally occurring in the wild in any single location, its heritage is a complex mix of these geographical areas.
