Guide

The species-level account. Cultivar pages build on this and say where they differ.

Hibiscus coccineus is a perennial in the mallow family that grows as a helophyte, a marsh plant rooted in consistently moist to wet ground. Give it strong light and keep the mix evenly moist, watering when the top inch begins to feel dry rather than letting it dry out fully. It tolerates wetter conditions than most houseplants, so err toward moist soil while still ensuring the pot drains.
