Later plantings can be successful, if the plants are watered well until established. Indoors, jasmines need at least four hours of direct sunlight daily or 14 to 16 hours of strong artificial light. South African Jasmine J. It blooms in the summer, bearing unscented white flowers in groups of three. Spanish Jasmine J. Italian Jasmine J. Clusters of fragrant, bright yellow flowers are present all summer. Primrose Jasmine J.
Downy Jasmine J. The stems and leaves have a downy coating, resulting in an overall gray-green effect. Intensely fragrant Confederate jasmine flowers.
Confederate jasmine or star jasmine Trachelospermum jasminoides is highly prized for its heavily scented clusters of phlox-like flowers, which bloom on twining stems in spring and summer. The new leaves are glossy light green and the mature leaves are a lustrous dark green, to 3 inches long. The 1-inch white flowers appear in small clusters on short side branches and they are attractive to bees. Landscape Use: Outdoors, Confederate jasmine can frame porches, accent trellises or, screen fences and walls, or be used as a groundcover.
Indoors, the vine will spill over the edges of hanging containers, or it can be trained on a small trellis. Cultivation: Confederate jasmine prefers sun to partial shade. A moist but well-drained soil to which leaf mold has been added is best. Yellowish leaves indicate the need for fertilizer, which should be applied in spring. Tie the stems to a fairly heavy support.
Pinch the tips to stimulate lateral growth and prune after flowering if necessary to restrain growth. If the vine is grown as a groundcover, trim the upward-twining stems.
Additional plants can be propagated from stem cuttings. The dark, dense foliage of Asian star jasmine. Indoors, Confederate jasmine grows best in bright indirect or curtain-filtered sunlight except in winter, when they need at least four hours of direct sunlight a day.
Problems: Confederate jasmine is relatively problem-free. Rabbits like to graze on this plant. Keep the soil moist throughout the first growing season as the roots become established. After planting, add two inches of mulch to conserve moisture in dry conditions. Once established, star jasmine tolerates some drought.
Fertilize star jasmine in spring as new growth emerges with an all-purpose fertilizer. Follow package directions carefully. Avoid over-fertilizing star jasmine, which will result in vigorous leafy growth with few blooms. Another common cause of limited blooming is a lack of sunlight.
Star jasmine can become invasive, especially in warm, moist conditions. Cut vines back to 18 inches after flowering to control its growth. Prune star jasmine grown as a groundcover throughout the year as it becomes unruly. Pinch back houseplants as needed to control growth.
Star jasmine suffers few disease or pest problems. Small, scale-like growths may look like a disease, but are actually scale, tiny insects that form in colonies on many plants. These insects pierce the stems and leaves to suck out the juices of the plant. Additionally, scale secretes honeydew, a sticky, clear substance which in turn attracts sooty mold, a black or grey fungus. Treat scale with an insecticidal soap or insecticidal oil when new growth emerges. Plant star jasmine so air circulates freely and thin the plants when they become crowded to prevent fungal diseases.
Confederate jasmine grows so quickly that it needs pruning to manage its size and keep it where you want it. Use clean, sterilized tools and perform your pruning right after the jasmine has flowered and blooms have faded. Clean and sterilize your tools after cutting any diseased areas before you continue pruning. To encourage the Confederate jasmine to grow fuller and more compact, you can cut it back to just beyond where it was pruned the year before.
Otherwise, cut any branches that are broken, damaged, dead, or appear diseased. Remove branches that cross others, cause congestion, or grow outward. Pruning helps keep the plant healthy by allowing air circulation and sunlight to reach the interior foliage. Confederate jasmine can withstand temperatures down to 10 degrees Fahrenheit without dying.
Once temperatures reach 10 degrees, the leaves will begin to drop off the plant. If the weather does not warm up and temperatures stay at or below 10 degrees, your Confederate jasmine will die back to the woody parts of the stems.
Exceptionally harsh winters or sustained low temperatures can cause Confederate jasmine to die down to the roots. In the event of a particularly cold spell, you can provide some protection for your Confederate jasmine by watering it deeply and covering it with a layer of mulch four or five inches deep.
Should your Confederate jasmine be damaged by the cold, after things have warmed up a little, prune to remove any broken or damaged stems to keep vermin or disease from using the damaged areas as an easy access point. If the jasmine has been damaged by the cold all the way down to the ground, you may need to cut it back all the way to ground level, then cover the roots with mulch and wait until spring to find out whether new growth sprouts which means that the roots lived.
Once new growth appears, provide the Confederate jasmine with a balanced fertilizer. It does very well in full sun but can also grow successfully in part sun or partial shade.
The more sun a Confederate jasmine is provided, the more bountiful its flowers will be. The root system of star jasmine plants proliferates with runners, so wherever the plant touches the ground, it puts down roots.
These roots create a network that grows deep and covers the entire area where the plant grows. You can grow star jasmine without a trellis as a ground cover, or you can train it to grow up a trellis or other support. Make sure your trellis is located somewhere that gets between full sun and partial shade so the star jasmine will thrive.
The soil should drain well and be rich, including organic material. Plant the star jasmine a few inches from the trellis. As the star jasmine grows, weave its long, trailing branches through the holes in the trellis, wrapping the stems of the plant around the slats of the trellis in the same direction that they naturally bend.
Tie the jasmine loosely to the trellis with the cloth; do not pull the fabric tight or cinch it when you tie the knot. Continue tying the branches to the trellis as the jasmine grows. Allow the jasmine to become well established, and provide fertilizer in the spring, when the plant begins to put out new growth. Feed Confederate jasmine with a fertilizer blend at a dosage of one and a half pounds per square feet of yard space. Apply the fertilizer evenly throughout your yard, avoiding the immediate vicinity of the jasmine plant.
Give newly established Confederate jasmine plants a smaller dose of one tablespoon of fertilizer per plant. Confederate jasmine plants can grow at a rate of three to six feet each year. However, your Confederate jasmine plant will spend its first year of growth developing its underground root system, without visibly developing much above ground.
It will increase production of above-ground foliage in its second year and, by its third year of growth, will be producing the typical three to six feet per year. Confederate jasmine blooms each year, beginning its flowering season in May and continuing through June. Confederate jasmine growing in containers will need to be watered at a different rate than Confederate jasmine planted directly in the ground. Although Confederate jasmine is drought resistant and can tolerate a dry climate, providing it with regular water will help the plant to flourish.
Give Confederate jasmine planted directly in the soil a deep watering when the top one to two inches of soil are dry. Water until the soil is wet to five or six inches deep.
You can test the moisture level of the soil by sticking your finger into the soil near your jasmine plant. Confederate jasmine growing in containers will need to be watered more frequently. The leaves of the Confederate jasmine vine are evergreen. At 10 degrees Fahrenheit or colder, the leaves will start to drop from Confederate jasmine plants. However, it has a tendency to spread heartily that leads some gardeners to call it invasive. Star jasmine is a perennial plant, which means it returns the next spring or persists over the winter.
You can get more information in our article Annuals vs. Perennials: What Is the Difference? Confederate jasmine and star jasmine are names for the same plant; both names refer to the plant whose botanical name is Trachelospermum jasminoides. Drought-tolerant in coastal zones, the plant goes into a tailspin when overwatering stresses or suffocates its roots. Water it thoroughly, and then let the soil dry slightly before you water again. Controlling moisture helps prevent nutritional deficiencies and capitalizes on soil nutrients, but star jasmine still benefits from an occasional boost.
Fertilize star jasmine once before new spring growth begins and again after flowering stops. Promote dense, healthy, ground-covering growth with a complete fertilizer such as a granular worked into the soil at a rate of 1.
Keep weeds under control as well, so your star jasmine doesn't need to compete for nourishment. Encourage branching in young star jasmine by regularly cutting back spreading stems.
This forces dense growth and side shoots, which bear the fragrant flowers. Once star jasmine reaches your desired height, annual pruning keeps it there.
Prune right after flowering each year and you won't sacrifice next year's blossoms. Remove wayward, upward-growing branches anytime. Use pruners or hedging shears, and wear gloves, long sleeves and protective eye wear.
