Gladiolus 'Atom'
While the *Gladiolus* genus has origins in Africa, Europe, and Asia, the cultivar ‘Atom’ is **not a wild species**. It’s a **hybrid**, specifically bred and developed by plant breeders.
Therefore, it doesn’t have a “native region” in the same way a wild plant does. Its origin is based on where the breeder developed it. While I don’t have exact details on *where* ‘Atom’ was bred, Gladiolus breeding tends to focus in regions with developed horticultural industries, such as **Europe, North America, or Australia/New Zealand.** I’d lean towards Europe or North America as more likely.
**In short:** It’s a cultivated hybrid, not a wild plant with a specific geographical origin. Likely developed somewhere in Europe or North America.
