2 (5)m, Moroccan Dragon Tree is a threatened and only in 1997 new described subspecies endemic to the Assif Amaghouz mountain range in the western Anti-Atlas in southwestern Morocco.

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 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 scottii (Scott's Hibiscus)

Hibiscus scottii (Scott's Hibiscus)

80 (120)cm, Scott's Hibiscus is an utmost desirable, extremely rare and endangered, evergreen small woody shrub from Socotra island, offshore Yemen, where it occurs in open spots in dry forests. It has small glossy dark green leaves and surprisingly large, rich yellow flowers with a small dark red center. For any rich, well drained substrate in full sun throughout the year and reduced watering in winter at a minimum of some 20°C. Hibiscus scottii is one out of five look-alike yellow flowering species which are endemic to Socotra, and which are easily confused: Hibiscus diriffan, Hibiscus macropodus, Hibiscus malacophyllus, Hibiscus quattenensis, and Hibiscus scottii. Socotra hosts even more yellow flowering endemic Hibiscus species (plus several probably introduced African species), yet these are more easily recognizable. Most (if not all) specimens which are labelled Hibiscus diriffan in cultivation are actually Hibiscus scottii. The problem has emerged as the original collection of Hibiscus scottii had been wrongly identified as Hibiscus diriffan, and probably all existing plants in cultivation descend from this single collection. Leaves in Hibiscus scottii are highly variable, they may have an obtuse, orbicular, or elliptical shape, the leaf margins are either entire, serrated or crenulate and the leaf base may be cordate, rounded, or truncate. Even a particular plant may change its leaf shape from a juvenile to an adult stage, and later in its adult stage again depending on cultivation conditions. Thus the leaf shape does not serve to identify plants. The only true distinctive and unique trait in Hibiscus scottii are very short rusty-brown hairs on the calyx and epicalyx, as well as the lower base outside the petals. Our plants are correctly identified and true-to-type. V-IX.

Hibiscus waimeae (Fragrant White Waimea Valley Hibiscus)

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 with an overall more compact growth habit, somewhat smaller rounded to broadly ovate leaves and slightly smaller white flowers with 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.

It makes a compact, basal rosette wth leathery leaves and rather large, sky-blue flowers. For any rich, well drained soil in a sunny spot. An excellent plant for the rock garden.

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.

5cm, Idaho Stonecrop is an only in 2010 described new species from the Salmon River Canyon in Idaho, USA. It makes a single basal grayish-green, pubescent leaf rosette and a bright yellow flower head. For any rich, very well drained and preferably rocky soil in a sunny spot. An excellent plant for a protected spot in the rock garden. Seeds from a certified wild collection in Idaho County, Idaho, USA, at some 600m. V-VI.

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.
