Star Jasmine (Trachelospermum asiaticum), also known as Asian Jasmine, is a versatile and resilient evergreen vine native to East Asia. This plant is admired not only for its beautiful, star-shaped flowers but also for its fragrant aroma and adaptability in various garden settings. While commonly grown outdoors as a vine or ground cover, Star Jasmine can also thrive indoors with the right care.
Growing Star Jasmine indoors allows you to enjoy its beauty and scent year-round, making it an excellent addition to your indoor plant collection. Whether you’re an experienced gardener or a beginner, Star Jasmine offers an easy-to-maintain option that adds elegance and a delightful scent to your outdoor spaces.
Characteristics
Star jasmine belongs to the Apocynaceae family and is a woody, evergreen vine that can be trained to grow as a ground cover or on trees and walls. The plant is known for its small, glossy, dark green leaves that provide a lush backdrop to the clusters of star-shaped white flowers it produces. The flowers typically bloom from late spring to early summer, filling the air with a sweet, intoxicating fragrance reminiscent of traditional jasmine, though it is not a true jasmine.

Care
Choosing the Right Container
When growing Star Jasmine indoors, the choice of container is crucial. Opt for a pot with good drainage to prevent water from accumulating at the bottom, which can lead to root rot. A pot with drainage holes and a saucer is ideal. The container should be large enough to accommodate the plant’s root system, allowing room for growth.
Soil
Star Jasmine likes its soil to be rich in organic content and well-drained. A high-quality potting mix with added perlite or sand for drainage works well. You can also mix in some compost to provide additional nutrients. The pH of the soil should be between 6.0 and 7.0, which is slightly acidic to neutral.
Light Conditions
Indoors, Star Jasmine needs plenty of bright, indirect light to thrive. A location near a south- or west-facing window is ideal, where it can receive several hours of sunlight each day. However, direct sunlight can scorch the leaves, so it’s important to provide some protection, such as sheer curtains or by placing the plant a few feet away from the window.
If natural light is insufficient, especially during the winter months, consider using a grow light to supplement the light levels. Aim for at least 6-8 hours of light per day to encourage healthy growth and flowering.
Watering
Proper watering is key to maintaining a healthy indoor Star Jasmine. It’s important to maintain the soil continuously damp but not soggy. Water the plant when the top inch of soil feels dry to the touch. During the growing season (spring and summer), you may need to water more frequently, while in the dormant season (fall and winter), reduce watering to prevent overwatering.
The plant should not be left submerged in water, as this can cause root rot. Always empty the saucer after watering to prevent standing water.
Humidity and Temperature
Star Jasmine thrives in warm, humid conditions. Indoor environments can often be dry, particularly during the winter months when heating systems are in use.
- Place the pot on a tray filled with water and pebbles, ensuring the bottom of the pot doesn’t touch the water.
- Use a room humidifier to maintain humidity levels between 50% and 60%.
- Mist the leaves regularly with water to add moisture to the air.
The ideal temperature range for indoor Star Jasmine is between 60°F and 75°F (15°C to 24°C). Avoid placing the plant near drafts, heating vents, or air conditioners, as sudden temperature changes can stress the plant.
Fertilizing
To encourage healthy growth and flowering, feed your indoor Star Jasmine with a balanced, water-soluble fertilizer every 4-6 weeks during the growing season. A fertilizer with equal parts nitrogen, phosphorus, and potassium (such as a 10-10-10 formula) is suitable. Fertilization should be reduced or stopped throughout the fall and winter months when the plant’s development slows.
Pruning and Training
Pruning is essential for maintaining the shape and size of your indoor Star Jasmine. Regular pruning helps promote bushier growth and can encourage more flowers. Trim back any long, leggy stems to keep the plant compact and tidy. In order to avoid new growth, pruning should be done in the early spring.
If you’re growing Star Jasmine as a vine indoors, you can train it to climb a small trellis or support. Gently tie the stems to the support structure with soft ties, being careful not to damage the plant.
Propagating
To propagate Star Jasmine (Trachelospermum asiaticum), take stem cuttings in spring or early summer. Cut a 4-6 inch healthy stem with a few leaves, remove the lower leaves, and dip the cut end in rooting hormone. Plant the cutting in moist, well-draining soil, and keep it in a warm, bright location with indirect sunlight. Maintain humidity by covering it with a plastic bag or placing it in a mini greenhouse. Water lightly and ensure the soil remains moist but not soggy. Roots usually develop within 4-6 weeks, after which the plant can be gradually acclimated to normal conditions.
Pest Control
While Star Jasmine is relatively resistant to pests, indoor plants can sometimes attract common houseplant pests like spider mites, scale, and mealybugs. Regularly inspect your plant for signs of pests, such as discolored or distorted leaves, webbing, or sticky residue. If you notice an infestation, treat the plant with insecticidal soap or neem oil and isolate it from other plants until the problem is resolved.
Growing Star Jasmine indoors can bring a touch of elegance and fragrance to your home. By providing the right light, water, humidity, and care, you can enjoy the beauty of this plant year-round. With its glossy leaves and fragrant flowers, Star Jasmine is a rewarding indoor plant that adds both visual and aromatic appeal to any indoor space.
