Although not a true jasmine, the star jasmine (Trachelospermum Jasminoides) has fragrant flowers similar to a true jasmine, so it's referred to as a jasmine. Also known as confederate jasmine, the plant is hardy outdoors in U.S. Department of Agriculture plant hardiness zones 8 to 10, but will grow in a container in any zone with the proper care. Mature plants will grow up to 20 feet tall with star-shaped white flowers and dark, glossy green leaves.
Things You'll Need
Plant the star jasmine in the center of an 8-inch-diameter container with drainage holes, using a medium mixture of equal parts peat moss, leaf mold and garden soil. The plant will grow 12 to 24 inches per year. Transplant the star jasmine to a container at least 2 inches in diameter larger when the plant outgrows its current container, which can be every one to two years.
Water the plant once a week to keep the soil moist, but not soggy. Test the top 2 inches of soil with your finger. If the soil is almost dry, water the plant thoroughly.
Feed the plant with a well-balanced fertilizer formulated for acid-loving plants once in the spring after the plant starts actively growing.
Keep the plant indoors when outdoor temperatures drop below 40 degrees Fahrenheit. The ideal temperature indoors is between 68 and 72 degrees Fahrenheit during the day and about 10 degrees cooler at night.
Place containers in a location where the star jasmine will receive indirect sunlight during the day. During the winter, the plant will need at least four hours of direct sunlight from an eastern or southern window.
Prune away tangled and straggly foliage in May after the star jasmine has stopped flowering if the plant container is kept outdoors. Plants that are kept indoors should be pruned in fall or winter after the plant has stopped growing. Only remove one-third of the vine. This will help promote branching and new growth.
