Gardenias have a sweet fragrance.

Gardenia bushes are evergreen shrubs that bloom in the spring. Gardenias have a fragrance that is often mimicked in candles and perfumes, so consider planting them near a window or an area of your yard where you can smell their sweet blooms. Gardenia bushes should be planted in the spring and fall.
Choose a location that is in full sun or partial shade. Avoid planting your gardenias under trees or plants that will drip water on top of them because water droplets can often cause fungus to grow on its leaves. The soil should be well draining.
Adjust the soil's pH level, if necessary. Its pH should be between 5.0 to 6.0. Test strips are available at your local home and garden store. To lower pH, add sulfur according to manufacturer directions, which will differ depending on the brand and your soil's pH.
Dig holes anywhere between 3 to 6 feet apart and only as deep as the bush's roots, but two or three times as wide.
Mix a little bit of compost and peat moss with the soil you just dug out to make your soil rich and to make it more conducive to retaining moisture. Do this only if the soil is in poor condition.
Take your gardenia bushes out of the containers and put them in the holes. Fill it half way with the soil and water. Then add the rest of the soil and water well. Add mulch, if desired.
