180 (240)cm, Mabberley's Hibiscus is an in 2023 new described species which is extinct in nature, where it was supposedly native to some Mascarene islands. Few specimens are still grown by botanical gardens and a handful of private cultivators, where this species had been labelled Hibiscus denisonii until recently. Hibiscus mabberleyi has finely pubescent leaves. There are at least two genetic lines still alive in cultivation, one with white flowers upon opening, later fading to very pale rose (photo), and a second and much rarer one with flowers which will stay white. 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 . Seeds from all Hibiscus species in section Lilibiscus (e.g Hibiscus arnottianus, Hibiscus cooperi, Hibiscus x denisonii, Hibiscus fragilis, Hibiscus genevii, Hibiscus mabberleyi, etc.) germinate unevenly over a period of several months. Keep pots in a warm spot and the soil slightlly moist until germination will occur. Seeds are extremely scarce and they are supplied on a first-come-first-served basis. The tested germination rate is > 80% in this species under optimal conditions. VI-X. 5 seeds per package.
