Gardenia jasminoides is a broadleaf evergreen shrub valued for glossy dark green foliage and fragrant, creamy white flowers. It is known as gardenia, Cape jasmine, Cape Jasmine gardenia, and Cape jessamine, and belongs to the Rubiaceae family; the species is native to southern China and Japan.

Cultivars differ in size, flower form, and bloom timing. Gardenias can be grown in the landscape or in containers.

Gardenias grow best in rich, acidic, well-drained soil. Keep the root zone evenly moist without leaving it waterlogged; shallow roots are sensitive to disturbance, so minimize digging and competition from nearby tree roots. Prolonged shade can reduce flowering, and alkaline soil can cause yellowing foliage.

Remove spent flowers to encourage continued bloom, and monitor new leaves for yellowing, which can signal unsuitable soil pH or nutrient availability.
