Gardenia is a genus of flowering plants in the coffee family, Rubiaceae, native to the tropical and subtropical regions of Africa, Asia, Madagascar and Pacific Islands,and Australia.Many of the native gardenias of the Pacific Islands and elsewhere in the paleotropics possess a diverse array of natural products. Methoxylated and oxygenated flavonols, flavones, and triterpenes accumulate on the vegetative- and floral-buds as yellow to brown droplets of secreted resin. Many focused phytochemical studies of these bud exudates have been published, including a population-level study of two rare, sympatric species of the Fiji Islands, G. candida and G. grievei.The evolutionary significance of the gums and resins of gardenias in attracting or repelling invertebrate herbivores, has yet to be explored by ecologists.
