Gardenia is a genus of 142 species of flowering plants in the coffee family, Rubiaceae, native to the tropical and subtropical regions of Africa, southern Asia, Australasia and Oceania. The genus was named by Carl Linnaeus after Dr. Alexander Garden (1730 to 1791), a Scottish-born American naturalist. They are evergreen shrubs and small trees growing to 1 to 15 metres tall. The leaves are opposite or in whorls of three or four, 5 to 50 centimetres long and 3 to 25 centimetres 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 to 12 lobes (petals) from 5 to 12 centimetres diameter. Flowering is from about mid-spring to mid-summer and many species are strongly scented.

The Bushveld Gardenia is a lovely shrub or small tree, 3-7m high with long narrow glossy dark leaves with wavy margins and large white showy flowers that turn yellow as they age, from spring to summer. The fragrant flowers are followed by ornamental grey-green fruit with white encrustations. It has a medium growth rate unless it is grown in warm areas where it is quite fast growing. The fruits and roots are used medicinally in the treatment of a variety of ailments, including asthma, infertility, earache, sore eyes, epilepsy and headache. Ashes from burnt roots are placed on the chest as a treatment for pneumonia. Some local people also believe that this shrub will protect them from lightning in a magical way.
