Gardenias are delicate, tropical flowers that are associated with romance and secret love, according to The Flower Expert website. They were named for Alexander Garden, a South Carolina physician.
Gardenias originated in the tropical and subtropical regions of Africa, southern Asia, Australasia and Oceania. Gardenias prefer humidity, warm to hot days (preferably with some afternoon shade), and cool nights. They are a popular shrub in South Carolina, where weather conditions are ideal.
Ease of care
Gardenias require a lot of care and usually thrive only when they grown are in ideal conditions.
Gardenias bloom from May through July in all climates where they are grown, whether inside or out. In their ideal climate, the volume of blooms will increase. In addition, the flowers will be more robust and they may bloom again in the fall.
The leaves of the gardenia plant will stay green and glossy year-round, provided the plant is healthy.
Encourage indoor blooming of gardenias with the use of grow lights and by maintaining a consistent inside temperature of 65 degrees. In addition, you can help create an artificial tropical environment by using misters.
