I've planted Swamp Hibiscus in Zone 8 of Georgia (U.S) in both wet and dry soil. In wet soil the plant grows to 6 feet or so in height with about an equal spread. We planted one out in front of our nursery in dry soil, with no irrigation, and though it survived a few years and actually produced a few blooms, it wasn't nearly as robust as the one planted in consistently moist soil. This plant is perfect for areas in the landscape or garden that have moisture-retentive soils, and you can grow it in a container submerged in the garden pond to a point where the top edge of the container is at or above the water surface. Swamp Hibiscus blooms about the entire summer.

I allow Swamp Hibiscus to go completely dormant during winter then cut the dead branches back to short stumps in late winter or early spring.
