Hibiscus dasycalyx

Neches River rosemallow

Hibiscus dasycalyx is a lovely Hibiscus quite unlike any other! Growing 3-4' tall, the deeply lobed red-green foliage of this rosemallow adds textural interest to the rain garden with their big white flowers with red throats that bloom from mid-summer till frost. The seedheads are red in color and mature to a deep brown, lending structure to the winter landscape and seeds for hungry songbirds.

Neches River rosemallow Interesting Notes

Hibiscus dasycalyx, commonly known as Neches River rose-mallow, is a rarely found perennial of the mallow family whose native territory is limited to three populations in seasonally inundated and regularly flooded bottomland areas near the Neches, Angelina and Trinity rivers in eastern Texas. Further declines in these native populations are currently threatened by a number of factors, primarily including habitat loss and genetic contamination of the species via interspecific hybridization... Three additional populations have now been introduced and established in eastern Texas in order to expand growth and help protect the species from further decline or possible extinction in the wild.


Hibiscus dasycalyx was designated in September of 2013 by the U.S. Fish and Wildlife Service as a Threatened Species under the Endangered Species Act of 1973, as amended. - Missouri Botanical Garden

Hibiscus dasycalyx Growing and Maintenance Tips

Obligate wetland plant that grows best in organically rich, moist to wet soils in full sun but can tolerate part sun. Best performance in areas with good air circulation, adequate moisture, and bright light. Cutting back plant in autumn to 3-4in tall will rejuvenate for the next season. 


Deeply lobed foliage helps with the appearance of sawfly damage but in gardens with high Japanese beetle density and subsequent damage, plants may be defoliated without adequate preventative measures.
