Delphiniums (Delphinium)

Delphiniums, particularly the most well-known species in cultivation, have a complex geographical origin, but here’s a breakdown:

* **General Genus (Delphinium):** The genus Delphinium has a wide distribution across the **Northern Hemisphere**. You can find various species in Europe, Asia, and North America. They are often associated with **temperate regions**.

* **Cultivated Delphiniums (Hybrids):** The tall, showy Delphiniums commonly grown in gardens are usually hybrids derived from species native to:
* **Europe:** Several species are native to Europe, particularly Southern Europe.
* **Asia:** A significant number of species originate in Central and Eastern Asia, including Siberia.
* **North America:** A few species are native to North America, however, these are rarely bred into the popular hybrid varieties.

The specific origins of individual hybrid cultivars can be traced back to the species involved in their breeding, often involving complex crosses between European and Asian species.

**In summary:** While the genus as a whole is found across the Northern Hemisphere, the cultivated varieties of Delphiniums we most often see are likely to have their roots in **Europe and Asia**.
