Hibiscus arnottianus (Arnott's Hibiscus)200 (500)cm, Arnott's Hibiscus (Kokiʻo Kea or Koki'o Keokeo in Hawaiian language) is an evergreen tall shrub native of the Koʻolau mountains on Oʻahu island, Hawaii, USA. Hibiscus arnottianus is among the also Hawaiian endemic Hibiscus hannerae, Hibiscus immaculatus, Hibiscus punaluuensis and Hibiscus waimeae the only slightly violet or rose fragrant Hibiscus species in its genus. It has dark green, usually slightly glossy, glabrous leaves and quite large, pure white flowers with narrow petals and a long protruding reddish pistil. For any rich, well drained substrate in a partially shaded (summer) to sunny (winter) spot at a minimum of some 15°C. All plants offered as Hibiscus arnottianus with slightly rose or yellowish flowers are inevitably hybrids with Hibiscus x rosa-sinensis cultivars. The same applies to all white flowering plants with a reddish center - plants from true Hibiscus arnottianus always have a white center. Our plants are unhybridized, true-to-type and self-fertile with pure white flowers and a white center. Hibiscus arnottianus, the very closely related Hibiscus immaculatus, and Hibiscus punaluuensis have the narrowest petals of all Hawaiian endemic white flowering Hibiscus species. Any plant with significantly broader petals than the one shown in the photo from one of our mother plants is a hybrid or a wrongly identified different species. Even several Hawaiian based nurseries erroneously sell obviously hybridized plants with broad petals as pure Hibiscus arnottianus. The cultivar called Hibiscus arnottianus 'Wilders White' cultivar with broad petals is actually not a cultivar from the pure species, but a hybrid between Hibiscus arnottianus and possibly Hibiscus punaluuensis, and hence the correct naming would be Hibiscus 'Wilders White'. And to make confusion complete, some Hibiscus x rosa-sinensis hybrids with a red inner eye are being erroneously offered as 'Wilders White', whereas the real 'Wilder White' is entirely white, without any inner red eye. Be it as it is, from us you will get the true unhybridized species. VIII-XII. |

Hibiscus cf. genevii (Rose Mauritius Mandrinette Hibiscus)150 (200)cm, Rose Mauritius Mandrinette Hibiscus is a rare and highly endangered, evergreen wild species from the island of Mauritius, where is was thought to be extinct until a couple of plants were rediscovered in 1968. The pure species has small leaves and rather large, very ornamental, pale rose flowers. In cultivation there is one genetic line present (our seeds) which most likely is of hybrid origin with probably Hibiscus boryanus as the second elder. Juvenile leaves in these plants are needle like and correspond to the species, however flowers have a somewhat different color with a more orange to salmon tinge. Hence we offer these seeds as Hibiscus cf. genevii, as the identity of these plants is still unclear. 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. Seeds from all Hibiscus species in section Lilibiscus (e.g Hibiscus arnottianus, Hibiscus cooperi, Hibiscus denisonii, Hibiscus fragilis, Hibiscus genevii, etc. ) germinate unevenly over a period of several months. Keep pots in a warm spot and the soil slightlly moist until germination will occur. IV-VII. |

Hibiscus fragilis (Orange Mauritius Mandrinette Hibiscus)70 (120)cm, Orange Mauritius Mandrinette Hibiscus is an orange flowering form which is known from a single population only in western Mauritius. Apart from the flower color it differs in several aspects from the nominal red form, having a more erect habit and bearing small leathery, more densely pubescent, mid green leaves. It will probably be separated as a subspecies in the closer future. 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. Seeds from all Hibiscus species in section Lilibiscus (e.g Hibiscus arnottianus, Hibiscus cooperi, Hibiscus fragilis, Hibiscus genevii, Hibiscus mabberleyi, Hibiscus waimeae, etc.) germinate unevenly over a period of several months. Keep pots in a warm spot and the soil slightly moist until germination will occur. A first time offer, and seeds are worldwide exlusively available from us. III-X. |

Hibiscus fragilis (Pink Mauritius Mandrinette Hibiscus)50 (90)cm, Pink Mauritius Mandrinette Hibiscus is an extremly rare and highly endangered, evergreen wild species from the island of Mauritius. It has a slightly prostrate habit and bears small leathery dark green leaves and ornamental, and for size of the plant rather large, rich pink (orange in an extremely are form) flowers. 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. Seeds from all Hibiscus species in section Lilibiscus (e.g Hibiscus arnottianus, Hibiscus cooperi, Hibiscus fragilis, Hibiscus genevii, Hibiscus mabberleyi, etc.) germinate unevenly over a period of several months. Keep pots in a warm spot and the soil slightly moist until germination will occur. Between around 2017 and 2022 a wholesale company had been distributing wrongly identified seeds from probably a hybrid under the name of Hibiscus fragilis, and several resellers resold these false seeds worldwide. Our seeds are from true, unhybridized, true-to-type plants being cultivated by ourselves, and the photo shows a flower from one of our mother plants. From us you will get the real deal. III-VII. |

Hibiscus insularis (Phillip Island Hibiscus)120 (200)cm, Phillip Island Hibiscus is one of the most endangered plant species in the world. Hibiscus insularis was down to just two genetically distinct specimens in habitat on Phillip Island, south of Norfolk Island, 1.400 km offshore eastern Australia. It is a medium tall evergreen shrub with leathery, shiny dark green leaves with crenulate margins and very showy, greenish-yellow flowers turning to dark rose at maturity, and with an reddish violet eye. On adult specimens flowers are set in abundance, yet seed set is extremely erratic despite careful hand pollination. Most plants in cultivation are from cuttings from the last two wild specimens, thus the genetic variation is extremely low in this species, and which may be the cause of a very low seed set. Also, germination in this species in unpredictable and it will take several months to almost an entire year. As a matter of fact, it is probably the most complicated species we have to get going from seeds. Our seeds were collected in March 2024 and are as fresh as they can be. Each single seed is visually inspected and all potentially unviable seeds are discarded. Germination tests yielded a germination rate between 15% to 25% under optimal conditions. However, we cannot give any guarantee on germination. In the best case you may be able to raise some 1 to 2 seedlings from one seed package, in the worst case there will be no germination at all. So be prepared not to have any success! Sowing is the very same as for other tropical Hibiscus species. Prior to sowing preferably soak seeds for 48 h in luke warm water. Use any rich, well drained substrate and keep pots at around 25°C in a partially shaded spot. In their first years seedlings will look very differently from adult plants. Leaves in immature plants will be very small and strongly lobed, upon maturity leaves will develop their adult and more round shape. For any rich, well drained substrate in a partially shaded (summer) to sunny (winter) spot at a minimum of some 20°C. V-X. |

Hibiscus mabberleyi spec. nov. (Mabberley's Hibiscus)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. |

Hibiscus punaluuensis (Fragrant White Aloalo Hibiscus)250 (500)cm, Fragrant White Aloalo Hibiscus (syn. Hibiscus arnottianus ssp. punaluuensis) is an endangered, tall evergreen woody shrub native of the Ko'olau Range on O'ahu, Hawaii, USA. It is one out of few slightly fragrant Hibiscus species which are all endemic to the Hawaiian archipielago. Hibiscus punaluuensis has dark green, large oval leaves and showy slightly fragrant pure white flowers with a long protruding reddish pistil. Whereas most hibiscus species in section Lilibiscus can be easily propagated by semi woody stem cuttings, for us this has proven extremely difficult in Hibiscus punaluuensis, as only one out of several dozens cuttings may eventually root. So the easier way for propagation is via seeds. Our seeds are from pure, unhybridized, true-to-type plants. For any rich, well drained substrate in a partially shaded (summer) to sunny (winter) spot at a minimum of some 15°C. VI-X. |

Hibiscus waimeae (Fragrant White Waimea Valley Hibiscus)200 (450)cm, Fragrant White Waimea Valley Hibiscus (or locally also called "Koki'o ke'o ke'o") is a critically endangered, tall evergreen woody shrub endemic of the Waimea and adjacent valleys in the western and southwestern parts of the island of Kauaʻi, Hawaii, USA. It is one out of few slightly fragrant Hibiscus species which are all endemic to the Hawaiian archipielago. Hibiscus waimeae is very similar to Hibiscus punaluuensis and differs in an overall more compact growth habit, somewhat smaller rounded to broadly ovate leaves and slightly smaller white flowers with significantly broader petals and a shorter, intense reddish pistil. Our seeds are from pure, unhybridized, true-to-type plants. For any rich, well drained substrate in a partially shaded (summer) to sunny (winter) spot at a minimum of some 15°C. VI-X. |

Nesocodon mauritianus (Blue Mauritius Bellflower)30 (50)cm, Blue Mauritius Bellflower is a highly threatened and extremely rarely cultivated perennial, with semi-woody stems, narrow lanceolate, dark green, serrated and glossy leaves and quite large, beautiful bright plum blue bellflowers with orange-red nectar drops inside. For any humus rich, well drained soil and a winter minimum of some 15°C in a sunny (winter) to partially shaded (summer) position. If we had to rate its overall rarity in nature as well as in cultivation, the Blue Mauritius Bellflower would range among the top 10 in our catalogue! V-VIII. |

Puya raimondii (Queen of the Andes)300 (450)cm ø, Queen of the Andes is native of Peru and adjacent areas and makes the tallest inflorescence of all plants, eventually reaching up to 8m in height. It is an extremely rarely seen plant in cultivation and makes a huge, short stemmed and unbranched leaf rosette before the impressive inflorescence is produced with several thousand pale yellow flowers after some 40 to 80 years (!) in habitat. However, cultivated plants will reach flowering size much earlier after some 20 to 35 years "only" under appropiate growing conditions. The entire plant will gradually die down after setting seed, and propagation is by seeds only. Keep slow growing plants slightly drier in winter at a minimum of some 10°C and in full sun throughout the year. Seeds are rarely available and only few packages are in stock. Tested viability of our seed stock is above 80% under optimal sowing conditions. |

Tapeinochilos palustris (Black Wax Ginger)200 (300)cm, Black Wax Ginger is a rarely cultivated, evergreen tropical species. It makes tall stalks with a dense terminal head of dark greyish-maroon to almost black bracts. The name Tapeinochilos palustris has been used in the garden trade since 1996, however the species has not been officially published yet as of 2024. Thus the name should better be referred to as Tapeinochilos palustris spp. nov. ined. For any humus rich, well drained substrate at a minimum of some 20°C and in winter with slightly reduced watering. Sowings require sufficient heat to germinate. The optimal temperature range is between 25°C and 30°C. Lower temperatures will significantly slow down the germination process or may even inhibit it. V-VIII. |
