Trachelospermum jasminoides, commonly known as Star Jasmine is a popular flowering plant that is native to China and Japan. It is a vigorous, evergreen vine that is loved by many New Zealand gardeners for its beautiful, fragrant flowers and attractive foliage. Star Jasmine is a woody, twining vine that can grow up to 10 meters long. It has glossy, dark green leaves that are oval in shape and up to 7cm long. The flowers are small, white, and star-shaped with a sweet, jasmine-like fragrance. They appear in summer and continue to bloom until autumn.
Star Jasmine was first introduced to the Western world in the late 1800s by a British plant hunter, Robert Fortune. He discovered the plant growing in China and Japan and brought it back to Europe, where it quickly became a popular garden plant. In New Zealand, it has been a favourite among gardeners for many years due to its beauty and hardiness.
It is a versatile plant that can be used in a variety of ways in the garden. It can be grown as a climber on walls, trellises, and fences, or as a ground cover. It is also an excellent choice for covering unsightly structures such as sheds or walls. Star Jasmine prefers a warm, sheltered spot in the garden with well-draining soil.
 
Watering
Star Jasmine requires regular watering, especially during dry periods. However, it is important not to overwater the plant as this can cause root rot.
 
Feeding
Star Jasmine benefits from regular feeding with a balanced fertilizer during the growing season. This will help to promote healthy growth and abundant flowering.
 
Overwintering
In New Zealand, Star Jasmine is hardy in most regions and does not require any special overwintering care. However, if you live in an area that experiences severe frosts, it is best to protect the plant by covering it with a layer of mulch or hessian.
 
Pruning
It responds well to pruning and can be trained to grow in a particular direction or shape. Pruning should be carried out after flowering to promote bushy growth and prevent the plant from becoming too woody. It is important to wear gloves when pruning Star Jasmine as the sap can be irritating to the skin.
 
Propagation
Star Jasmine can be propagated from semi-hardwood cuttings taken in late summer or early autumn. The cuttings should be around 10cm long and planted in well-draining soil. They should be kept moist and warm until they have rooted.
 
Diseases and Pests
It is generally a hardy plant and is not prone to many diseases or pests. However, it can be affected by powdery mildew if grown in humid conditions. Regular pruning to promote good airflow around the plant can help to prevent this. Spider mites and mealybugs can also be a problem, especially if the plant is stressed or not watered enough.
 
Plants to Pair with It
Star Jasmine looks beautiful when paired with other climbers such as Clematis, Wisteria, and Honeysuckle. It also makes an excellent companion plant for shrubs such as Camellias and Azaleas.
