Gardenias are native to the tropical and subtropical regions of Africa, southern Asia, Australasia and Oceania. This species can be difficult to grow elsewhere because it demands high humidity to thrive and bright (not direct) light. Some types of gardenias can be grown as houseplants.
Gardenias are very fragrant creamy-white flowers with glossy, dark-green leaves. Gardenia flowers are solitary or in small clusters, white or pale yellow. The gardenia flowers are with a tubular-based corolla with 5-12 lobes petals from 5-12 cm diameter.
Gardenia plants are evergreen shrubs and small trees growing to 1-15 m tall. The Gardenia plant leaves are opposite or in whorls of three or four. They are dark green and glossy 5-50 cm long and 3-25 cm broad, with a leathery texture. They are simple, entire, hairless, with wavy margin.
