Beloved for their intoxicating fragrance and attractive, waxy, creamy-white flowers contrasting beautifully with their shiny, leathery, dark green leaves, Gardenias are irresistible heat-loving evergreen shrubs or trees. Native to the tropical and subtropical regions of Africa, southern Asia, Australasia and Oceania, Gardenias are not the easiest shrubs to grow, but their exquisite fragrant flowers make up for the extra attention they require.

Over 200 Gardenia varieties are available in a wide range of height, flower size and color, leaf size and color, blooming time and duration, and shrub habit. Gardenia plants usually grow from 2 to 12 ft tall and wide (60 - 360 cm), depending on the variety. 

Here is the list of the most popular medium-sized Gardenia cultivars. Prolific bloomers, they can be used as sweetly fragrant evergreen accents, low flowering hedges, and pretty container plants.
