| General Description | Hardy, evergreen, woody climber about 12 m in height, with twining stems, glossy dark green,
oval leaves, often turning deep bronze-red in winter and clusters of highly fragrant, white
flowers. Star jasmine is in a different family (Apocynaceae) than the true jasmines in the genus
(Oleaceae). |
| ID Characteristic | Star Jasmine is identifiable by bruised twigs and petiole with milky white latex. Flowers are
white, remarkably fragrant, salverform with pinwheel-like lobes. Leaves are opposite and
brilliant dark green. |
| Shape | Vigorous climbing evergreen. |
| Landscape | In frost-free areas, you can train Star Jasmine to grow on a trellis, over an arbour, as an espalier
against a wall or fence, as a border plant or hedge, to spill over a wall. It is also suited to
containers with smaller plants. Too can be used as an evergreen groundcover under tall trees.
In areas prone to severe frost, you need to protect it in a greenhouse or conservatory during the
winter. |
| Propagation | Star jasmine can be propagated through cuttings, seeds and layering.
Cuttings best achieve the successful propagation of Star Jasmine. During the spring or early
summer, cut a 25- to 30 cm length of the vine from a star jasmine plant. Cut just below a node, a
slight swelling where a leaf or bud emerges. Divide the vine into 8 to 10 cm stems, each cut just
below a node. Ensure that the milky sap excreted from the cutting has dried out before inserting
the cutting into the soil. After cuttings have rooted (generally two to three weeks) move it into a
pot with a good garden loam mix.
For seed propagation, soak the seeds in warm water overnight. Then sow the individual seeds
into seed compost. The germination time for seeds is usually around 4-6 weeks. |
| Cultivation | Trachelospermum jasminoides prefer partial or full shade and moist, well-drained soil but are
adaptable to a wide range of conditions, including full sun. It is subject to winter kill
to the ground when grown in full sun. This vine is moderately salt tolerant but not cold, hardy. It
requires pH soil from 4.5 to 8.
If growing indoors, plant in loam-based potting compost in full light but not direct sun. |
| Pests | Susceptible to cushion scale. Under glass can be affected by mealybugs and glasshouse red
spider mites. Generally disease-free and deer resistant. |
| Notable Specimens | Real Jardín Botánico, Madrid, Spain. |
| Habitat | Sunny edges of forests, brushwoods at elevations from 200 - 1,300 m in eastern and southeastern
Asia, Japan, Korea, southern China, and Vietnam. |
| Bark/Stem Description | Regarding the bark, it does not have a showy bark texture. Stems are slender, rounded, dark
