Opinion
"
Trachelospermum jasminoides is perhaps one of the most beautiful perennial climbers due to its bright green leathery leaves, dense vegetation, and delicate flowers. The flowers are cream-white, starry, small but numerous and deliciously scented. It can reach a height of twelve meters if it has support to climb, and although growth is slow during the first years, it will grow faster in the following years. It is such a versatile plant that can grow vertically, but is also amazing horizontally as a groundcover, creating an attractive bright green carpet. It is easy to grow, almost disease-free, and fast-growing. You will find everything you want from a creeping in Star Jasmine.

| 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). |
| 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, or to spill over a wall. It is also suited to containers with smaller plants. It can also 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. |

| Trachelospermum jasminoides prefer partial or full shade and moist, well-drained soil but is 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. |

| 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. Sow the individual seeds into seed compost. The germination time for seeds is usually around 4-6 weeks. |
