Order: Gentianales
Family: Rubiaceae

Gardenia is a genus of flowering plants in the coffee family native to the tropical and subtropical regions of Africa, southern Asia, Australasia and Oceania. They are evergreen shrubs and small trees growing to 1–15 metres (3.3–49 ft) tall. The leaves are opposite or in whorls of three or four, 5–50 centimetres (2.0–20 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 5–12 centimetres (2.0–4.7 in) diameter. Flowering is from about mid-spring to mid-summer and many species are strongly scented.

Gardenia jasminoides (syn. G. grandiflora, G. florida) is cultivated as a house plant. This species can be difficult to grow because it originated in warm humid tropical areas. It demands high humidity to thrive and bright (not direct) light. G. jasminoides grows no larger than than 18 inches in height and width when grown indoors. In climates where it can be grown outdoors, it can attain a height of 6 feet. If water hits the flowers, they will turn brown.
