180 (240)cm, Mabberley's Hibiscus is an in 2023 new described species which is extinct in nature. It was supposeldy native to some Mascarene islands. Few specimens are still grown by botanical gardens and very private cultivators, and these plants had been labelled Hibiscus denisonii in the past. There are at least two genetic lines still alive in cultivation, one with pure white and the other with very pale rose flowers (photo), which later fade to almost white as well. The rose flowering form is sometimes confused with Hibiscus x denisonii or Hibiscus storckii, which both are different taxa. All plants sold as Hibiscus storckii are in fact Hibiscus cooperi. Easily grown in any rich, well drained substrate in full sun throughout the year and reduced watering in winter at a minimum of 20°C. True to type seeds are worldwide exclusively available from Rareplants.eu .
