Detailed Information

The native region of **Hardy Hibiscus (Hibiscus moscheutos)**, and therefore the likely origin of cultivars like ‘Kopper King’, is **eastern North America**. Specifically, it’s found in wetlands, swamps, and along riverbanks from southern Canada down to Florida and west to the Mississippi River.

While cultivars like ‘Kopper King’ are bred and developed in nurseries worldwide, their genetic lineage traces back to these native North American Hibiscus moscheutos plants.
