Cape Jasmine – or Gardenia radicans as it’s better known – is a fantastic low growing Gardenia suitable for full sun or part shade positions. Like all Gardenias, this one also has highly perfumed flowers, often produced on-mass during Spring and Summer. Although it will handle cool conditions and even light frost, this plant is best grown in a tropical or subtropical climate such as what we experience here in Brisbane.

An adaptable plant, Gardenia radicans will grow on a range of soil types in full sun or part shade. Full shade is not recommended as plants will grow long and leggy and flower very infrequently. Around a half day of sun is preferable in Brisbane, to give them some respite during our hot and dry periods. Although adaptable, all Gardenias need an acidic soil to thrive (pH 5.5-6.5). They will perform best if the soil is also rich with organic matter, so add compost to the garden bed at the time of planting. Feed regularly to maintain a vigorous plant.

Gardenia radicans is generally pest-free. However, scale can be a problem sometimes, as can mealybug. Treat with a systemic insecticide for best results. Over watering, especially in winter, can cause leaf yellowing followed by leaf drop. Plants kept too soggy will also become susceptible to rot rot and other fungal diseases. Prune lightly once or twice a year to maintain nice tight growth.
