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.
