Gardenia jasminoides (Cape Jasmine)

What are the garden uses for Gardenia jasminoides in NZ?

Gardenia jasminoides is a much-loved shrub that is perfect for creating garden appeal. It can be clipped into a hedge, included in a mixed planting, planted around outdoor living areas, included in tropical or “white” gardens, or maintained in a container. It is an excellent complement to a modern or cottage garden, bringing fragrance and elegance to a space. It is the gorgeous foliage and flowers that make this Gardenia an excellent choice for a NZ garden.

Gardenia jasminoides hedge spacing

The optimum plant spacing for a Gardenia jasminoides hedge is 40 cm between the plants. Spacing the plants out further will result in a wider hedge that takes longer to fill in. Be sure to use a string line to ensure the line is straight, and start lightly trimming the sides once the plants show active growth. It makes a lovely hedge 80-120 cm tall. The best Gardenia jasminoides hedges are achieved with trimming in spring and again in autumn.

What height does Gardenia jasminoides grow to?

Gardenia jasminoides grows to about 1.5 m tall and the same wide as a general rule. It tends to grow taller in partial shade conditions compared to when grown in full sun. Similarly, the size also depends on the level of trimming and how well the plant is cared for with regard to fertiliser and watering during dry periods.

What growing conditions are best for Gardenia jasminoides?

Gardenia jasminoides grows best in full sun or partial shade on a well-drained site. It is tolerant of light frost only and does require shelter from wind. A soil rich in organic matter that does not dry out during summer is ideal. Clay soil, heavy soils, or areas with excessive moisture should be avoided, as the plants will struggle and are likely to fail. Heavy shade positions should also be avoided. The goal is to ensure they receive reasonable amounts of dappled sunlight, or about 3-4 hours of direct sun per day.

Gardenia jasminoides tree care

Gardenia jasminoides can be susceptible to various problems if not correctly cared for. Gardenias are acid-loving plants, and alkaline soils can lead to nutrient deficiencies, particularly iron chlorosis, which causes the leaves to yellow. It is essential to ensure the soil is acidic and to use acidic fertilisers. Both overwatering and underwatering can cause problems. Overwatering leads to root rot, while underwatering causes wilting and bud drop. They need consistent moisture and a well-drained soil. Common pests include aphids, whiteflies, mealybugs, scale insects, and spider mites. Gardenias are susceptible to fungal diseases like powdery mildew, leaf spots, anthracnose, and sooty mould. Both pests and diseases can be easily controlled with an appropriate agrichemical, but only if their levels start to impact the aesthetics and health of the plant.

Gardenia jasminoides propagation

Gardenia jasminoides is easily propagated from stem cuttings. Semi-hardwood cuttings are usually taken from autumn until mid-spring. A stem about 8-10 cm long is trimmed into a cutting using secateurs with 2-3 leaves at the top and just below a node. A nick is taken off the base of the cutting to expose more tissue. The cutting is dipped in rooting hormone, then inserted into pumice. The tray of cuttings is placed under mist with bottom heat also applied. The cuttings will typically take root within five weeks.
