gardenias are heat-loving evergreen shrubs, best known for beautiful white fragrant flower.Gardenias are named for 18th century South Carolina botanist Dr. Alexander Garden. They are native to China, Japan and Taiwan.

Prune shrubs after they have finished flowering to remove straggly branches and faded flowers. A good time to fertilize gardenias is mid-March with a second feeding in late June if you want to encourage faster growth for young shrubs but do not fertilize while in bloom.


Select a site with full sun to light shade and moist, rich, well-drained soil. Gardenias prefer acidic soil with a pH between 5.0 and 6.0. they like to be protected from early morning sun which can cause sunburned foliage

Gardenias require at least an inch of rain (or equivalent watering) each week. Avoid disturbing the roots ofthe plant as they are shallow, keep a few inches of mulch around your plant to keep it moist and weed free.

Most varieties of Gardenia only bloom once a year, though breeders have developed a few varieties that can bloom more than once a year. Before pruning your gardenia, make sure to check that the variety that you own only blooms once or has completed its blooming cycle if it does bloom more than once. Pruning should be done when the shrub is dormat.

Gardenias bloom best in when the daytime temperatures are warm but not hot and the nighttime temperatures are cool. Ideally, for the day, you want the temperatures to be between 65F to 75F during the day and between 55F and 60F at night.
white flies and mealybugs are the most troublesome insects, use horticultural oil or insecticidal soap to control these pests. In regions where the plant is marginally hardy, protect bushes from hard freezes and drying winter winds.

Hardy Kleims
hardy klems
is one Gardenia that does very well in the Carolinas
Kleim's Hardy is a petite shrub just 2 to 3 feet high and wide, very well-branched and densely clothed in glossy evergreen dark green leaves. The blooms are pure white, single and 6-petaled, and their scent is absolutely unforgettable.

Chuck Hayes
chuck hayes
is a relatively new introduction that is extra hardy.
Features large, sweetly fragrant, velvety white flowers but with increased cold tolerance. Lustrous foliage on a rounded evergreen shrub, useful as a low hedge, screen or accent for entryways. This shrub will bloom 4 weeks from late spring to early summer. Only pruning needs are to remove dead wood or shaping as this only reaches perhaps 4 feet. Pinch the tips of "Chuck Hayes" gardenia branches in the first year to encourage branching for a fuller plant.

grows to only about one foot tall with a spread of 2 to 3 feet, great for a ground cover, but it is not as hardy as some other varieties.

Dwarf Radicans Gardenia is a miniature version of a gardenia with all its fragrance and loveliness. Use it as a ground cover, container plant, or in a low border. Once established, this hardy variety becomes easy to maintain and is even drought-tolerant. Gardenia radicans thrive in full sun to partial shade and adapt to almost any soil.
