About

Hibiscus coccineus the scarlet rosemallow, is a hardy Hibiscus species, also known as Texas star, brilliant hibiscus and scarlet hibiscus. In 2025, the name was changed to Muenchhusia coccinea.

The plant is found in swamps, marshes and ditches on the coastal plain of the Southeastern United States. It is native from Southeastern Virginia south to Florida, then west to Louisiana. Despite its common name Texas star, the plant is not found naturally in Texas. In addition to the scarlet-flowering variety, a white-flowering variety is also known as the white Texas star or lone star hibiscus.
