Star Jasmine is a woody perennial vine grown outdoors in USDA Plant Hardiness Zones 8 through 10 and indoors in colder climates. Also known as Confederate Jasmine or by its scientific name of Trachelospermum jasminoides, the flowers have a pleasant jasmine fragrance and will grow on a fence or trellis. Star Jasmine can also be trimmed to a bushy shape, used in hanging baskets or as a spectacular ground cover. To care for a Star Jasmine vine indoors or out, provide adequate sunlight and regular watering.
Locate the plants in full sun to partial shade if planted in the garden or in a container outdoors. The vine thrives indoors on indirect light throughout the summer but needs at least 4 hours of direct sunlight in the winter. Indoor plants can be placed outdoors in the summer, but don't place them in direct sun at first or they will burn.
Water as soon the top of the soil feels dry during the spring and summer. Occasional misting should be done with distilled water when the air is particularly dry in the summer. In the fall, water the plant once every other week and cut back watering to once a month in the winter. Place indoor plants on a tray filled with pebbles and water. Do not allow the plant to sit directly in the water, just on top of the pebbles. This will provide the plant its required humidity.
Apply a well-balanced fertilizer made for acid-loving plants once a month beginning in the spring. Discontinue fertilizing in mid-fall and begin again the following spring.
Prune and thin straggly branches in the spring after blooming has finished to promote a bushier plant. In the winter, cut off any dead or diseased branches. Cut the plant back for shaping after the last frost. Do not cut more than 1/3 of the vine at any one time.
