They are evergreen shrubs and small trees growing to 1–15 metres (3. 3–49. 2 ft) tall. The leaves are opposite or in whorls of three or four, 5–50 centimetres (2. 0–19. 7 in) long and 3–25 centimetres (1. 2–9. 8 in) broad, dark green and glossy with a leathery texture. The flowers are solitary or in small clusters, white, or pale yellow, with a tubular-based corolla with 5–12 lobes (petals) from 5 to 12 centimetres (2. 0 to 4. 7 in) diameter. Flowering is from about mid-spring to mid-summer, and many species are strongly scented. 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.
