Answer: The fruit of the gardenia flower is actually a berry, that doesn't germinate very well. Gardenia's are usually propagated from cuttings. If you want a greenhouse full of gardenia plants, take stem cuttings from a healthy plant, dip them in rooting hormone, and place them in regular potting soil. The cuttings should root within a few months (new green growth is a good indication that they've rooted). Since the plants are tropical in nature and picky about humidity and warmth, plan to spend some extra time providing for their needs.
