Hibiscus cf. genevii (Rose Mauritius Mandrinette Hibiscus)

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 (Pink Mauritius Mandrinette Hibiscus)

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)

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 September 2023 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 will be very narrow and partially lobed, with time plants will develop adult entire leaves. For any rich, well drained substrate in a partially shaded (summer) to sunny (winter) spot at a minimum of some 20°C. Seeds are extremely limited and are supplied on a first-come-first-served basis.

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

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)

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 x denisonii (Denison's Hibiscus)

Hibiscus x denisonii (Denison's Hibiscus)

120 (160)cm, Denison's Hibiscus is an old stabilized polyploid and fully fertile hybrid of probably three species, namely Hibiscus boryanus, Hibiscus fragilis and Hibiscus mabberleyi. The latter is an in 2023 new described species and was formerly included in Hibiscus denisonii. Hibiscus x denisonii is sometimes confused with Hibiscus storckii, which is a different species and which is actually not in cultivation. All plants sold as Hibiscus storckii are in fact Hibiscus cooperi. Hibiscus x denisonii is an evergreen species with glossy dark green, leathery leaves and ornamental, pale rose flowers with or without some more pinkish and bluish shade. If grown under glass petals tend to stay more whitish. Hibiscus x denisonii is one out of very few hybrids which will come true from seeds. This means that seed grown plants will be almost identical to the mother plant. 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. Only 8 packages are available. VI-X.

Puya raimondii (Queen of the Andes)

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)

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.
