Cape Jasmine Overview

Gardenia jasminoides is an evergreen, aesthetically pleasing shrub covered with fragrant white flowers during summer months. The Gardenia or Cape jasmine is a highly enjoyable addition to any subtropical or warm temperate garden. Not only is it an ornamental plant used in both the traditional medicinal and culinary applications, but the fruit is used as a yellow dye and the flowers are fragrant cut flowers. They make for beautiful specimen plants and also do well in containers. Native to the subtropical and tropical regions in Japan and southern China, this Gardenia ideally grows in moist but well-draining soils, rich in organic material and with an acidic pH. It grows well in full sun but during the warmer months, it needs some protection as the leaves might scorch or flower buds might drop. In cooler regions, they enjoy sunny spots but just ensure that roots are kept cool and moist with a thick layer of organic mulch.

Common problems with Cape Jasmine

Pests include whiteflies, mealybugs, scales, aphids and spider mites. Diseases include chlorosis, powdery mildew, leaf spots, dieback, anthracnose, and sooty mold.

How to harvest Cape Jasmine

Cut gardenia stems early in the morning or late in the evening, using sharp shears. Collect stems with flowers that are almost completely open.

How to propagate Cape Jasmine


Tender softwood or semi-hardwood cuttings taken in summer. Immediately place cuttings in suitable rooting medium.
