Q.Growing Indoor Gardenia, Zone 6b

Yes, they need bright light and a south facing window gives the most light in an indoor situation. I wouldn't put it right in the window but a foot or two back should be fine. In the winter you can move it closer. It needs high humidity, acid soil, and frequent fertilization to thrive. Here is more:

When I grew gardenias in pots, I selected a container with at least one good water drainage hole, rollers and a one-inch (or so) detached saucer to collect/catch any excess water (re-use the saucer water elsewhere or discard it). Provide about four hours of morning sun, afternoon shade or use a grow light with a timer. Do not forget to provide some ambient humidity. Consider moving them indoors once overnight temperatures typically fall below 60°F. If, during winter, you can measure lower temperatures where the pot is located, it is either too close to the window and-or the room temperature needs to be increased.
