Hibiscus (Tropical Hibiscus) & Pavonia
|
Hibiscus and Pavonia are mostly perennial evergreen to rarely deciduous shrubs, few tropical species are growing as annuals. All require a well drained substrate in full sun and plenty of water in summer. Tropical species should be kept drier in a sunny spot in winter at some 15°C to 20°C. Sow flat at a minimum of some 20°C in any rocky or sandy soil, keep pots always in full sun. 10 seeds per package, if not stated differently. Note on seed availability: All species in section Lilibiscus (e. g. Hibiscus arnottianus, Hibiscus boryanus, Hibiscus fragilis, Hibiscus kokio, etc.) as well as some other woody members (e g. Hibiscus insularis and Hibiscus scottii) are much sought after by collectors and are mostly very rare in cultivation. Seed set in most of these species is very irregular and unpredictable. Despite a continued flowering period from spring through early winter, our cultivated plants usually fruit around early summer (May and June) and then again in early autumn (September and October) only. Whereas in full summer heat all developing seed capsules are usually aborted. Thus you have the best chance to get a hold on one of these rare species by occasionally checking our webshop for new arrivals in early summer and early autumn. You find more Hibiscus species in this category: Hibiscus (Hardy Mallow) and Hibiscus (Swamp Mallow). A note on Hibiscus seeds being offered on several selling platforms: On severall well-known U.S. American, European and Chinese selling platforms you will find thousands and thousands hibiscus seeds on offer. And before you throw away your money, keep in mind the following. There does not exist any true blue, nor any vivid emerald green or any rainbow colored hibiscus. These are all photoshopped images and without any exception these offers are scams. Also, Hibiscus rosa-sinensis cultivars will never come 100% true from seeds. If you are lucky enough, you will receive at least some hibiscus seeds (and not some other plant species you didnt' want). However, the color in your plants will never be the one shown on the photo. In the best case your plants will be close, but they will never be identical - genetically this is simply impossible. Then never ever buy anything from any seller who may also offer: blue tomatoes, blue or violet strawberries, blue, pure black or rainbow colored roses, blue or rainbow colored chrysanthemums, rainbow colored grapes, true blue orchids, blue cucumbers, blue sunflowers, blue pumpkins, etc. All these are fakes and you will be scammed. Last but not least, it should ring your alarm bells, if a particular seller uses "borrowed" photos from the web without giving any credit to the image copyright owner. In most cases a simple reversed Google image search will reveal the real source for a particular photo. Serious sellers will always use photos taken from their own plants, or at least they will give credit, if they use a photo from a different source. U.S. customers only: Hibiscus seeds cannot be shipped to the U.S. |

Hibiscus x denisonii (Denison's Hibiscus)120 (160)cm, Denison's Hibiscus used to be a mysterious plant until 2023. Since a new revision and publication it is now regarded to be a very old stabilized polyploid and fully fertile hybrid, involving probably three species, namely Hibiscus boryanus, Hibiscus fragilis and Hibiscus mabberleyi. The latter was formerly included in the now superseded taxon Hibiscus denisonii, yet in 2023 it was separated and described as a new species of its own. While some other plants, formerly also included in Hibiscus denisonii, had been recognized to be of hybrid origin and thus these were renamed to present Hibiscus x denisonii (note the "x" in the new name!). Hibiscus x denisonii is sometimes confused with Hibiscus storckii, which is a different species and which at present does not seem to be in cultivation. All plants being sold as Hibiscus storckii are in fact Hibiscus cooperi. Hibiscus x denisonii is an evergreen plant with glossy dark green, leathery leaves and ornamental, pale rose flowers with some bluish shade, especially on the second day. If grown under glass petals tend to stay paler to almost white. It appears very likely that from Hibiscus x denisonii (or at least involving an offspring named 'Hale Blue') the very first bluish, maroon and greenish flowering, modern tropical hibiscus hybrids were created in the 50ties of last century. Unfortunately 'Hale Blue' hasn't been seen again for the past 30 years and is probably not in cultivation anymore. Hibiscus x denisonii almost shared the same fate with little more than a handful of specimens left at some point. Yet it could be saved in the very last minute and is now available again to the broader public. This will give new opportunities to create some more modern lines of bluish, greyish, maroon or greenish flowering tropical hibiscus hybrids. Hibiscus x denisonii is a stabilized hybrid which comes true from seeds. This means that seed grown plants will be almost identical to the mother plant with very little variation. It is 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 clayi, Hibiscus cooperi, Hibiscus x 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 3 packages are still available. VI-X. |

Kosteletzkya virginica (Virginia Saltmarsh Mallow)100 (150)cm, Virginia Saltmarsh Mallow is a herbaceous perennial with an erect, widely branching stem with hastate, finely pubescent leaves, and numerous medium sized bright rose flowers from late summer to early autumn. Kosteletzkya virginica is native of marshes and alongside wetlands from southern-east North America to Central America and Cuba. Some authors place Kosteletzkya virginica into Kosteletzkya pentacarpos from the Mediterranean region. Yet due to their extremely disjunct distribution and lack of genetic analysis, we keep this species separately. For any humus rich, well drained, always slightly moist soil or at the edge of a pond or stream in a sunny spot. Our mother plants have been grown from material which originally came from Florida, USA. VI-IX. |

Pavonia hastata (Spearleaf Swampmallow)100 (140)cm, Spearleaf Swampmallow is an ornamental perennial from South America (Brazil, Bolivia, Argentina, Paraguay, and Uruguay). It makes slender, somewhat prostate stems with narrow leaves and numerous light rose flowers in summer. Similar to several other Pavonia species, Pavonia hastata produces cleistogamous flowers in summer with long days and short nights, i.e. flowers produce seed without opening. With shorter days in autumn and spring, flowers open completely. Pavonia hastata is sometimes offered as Pavonia brasiliensis, which is an unresolved name. For any rich, well drained substrate in a sunny spot throughout the year. In winter keep drier at a minimum of some 15°C. V-VIII. |
