Tabernaemontana is a genus of around 100 species found throughout the tropics including; Asia, Africa, South America, oceanic islands and one species occurs in Australia. They belong to the Apocynaceae family which includes the popular tropical ornamental, Frangipani. Many species are used in traditional medicine or shamanic ceremonial preparations. Scientists have been studying alkaloides found in many species of Tabernaemontana, and researching their potential medicinal applications. Although poisonous the milky sap, leaves and flowers of these plants show great potential for the pharmaceutical industry.
The Paper Gardenia although rarely grown as an ornamental is easy to grow in warm temperate to tropical climate zones. It requires full sun, well drained soil enriched with organic material and benefits from a layer of surface mulch 50 - 100 mm thick. Relatively slow growing and drought sensitive when young it develops into a robust, disease free and resilient tree with age. Pruning is not required as it naturally forms an appealing dome shape with flowers held at the ends of the branches. Plants are often available for purchase at our Growing Friends Nursery, open Monday to Friday 11am - 2pm and Saturday 10am - 2pm.
