Jasmine polyanthum

Filed under: — admin @ 5:45 am


Jasmine polyanthum also referred to as winter jasmine, pink jasmine or Chinese evergreen jasmine is a native of China and a member of the Olive family (Oleaceae). It produces very fragrant, star-shaped white flowers that start as rosy, pink pointed buds. The woody trailer is a vigorous grower that can with support climb up to 20 ft outdoors. It is grown as a ground cover, on a trellis, in a container or in a hanging basket.

Care:
Jasmine prefers well-drained fertile soil. It needs at least 4 hours of bright direct sun and can be grown in full sun outdoors. Water regularly during the growing season and fertilize every 2-3 weeks with a high phosphorous fertilizer (15-30-15) to encourage blooming.
J. polyanthum is a seasonal bloomer that will set bud when exposed to temperatures below 60 F for 4-6 weeks. It blooms primarily in late winter into spring and then sporadically throughout the year.
In colder climates, bring the plant indoors when night temperatures reach 40 F or once the buds are set and place it in a sunny bright, cool location. J. polyanthum requires less water in the winter therefore water when the soil dries out.
Pruning
To control the vigorous growth, Jasmine needs frequent pinching. Cut the plant back after blooming and in the summer to control growth and prevent tangling. Repot into pots 1-2 sizes larger every 2-3 years in the spring after flowering.
Propagate in the summer from tip cuttings or by layering. They can also be started from seed which do not require stratification.
Problems
Spider mites aphids and scale. It can also be susceptible to iron chlorosis (yellowing leaves with dark green veins) which can be corrected by adding chelated iron to the fertilizer when needed.

  1. Hi. I was wondering if the jasmine plants can be put in hanging baskets. I haven’t found a site any where that mentions this. I’m afraid the will not get enough sun light hanging. Also, not sure how much or how often to water these plants. Located in S. Illinois. Thanks!

    Yes, the vining type of jasmines such as J. polyanthum can be grown in hanging baskets. There is no magic formula just water when the container feels light and top inch of soil is dry. Pay special attention to watering when the weather is hot and dry.

  2. I bought a jasminum polyanthum over the summer and nursed It back to health. It now covers a 4 ft trellis in a flower pot. I have not misted or put on a pebble tray. It just keeps growing. Is It to late to put Into a hanging basket? how do I go about pruning back? It Is not In a cool location at all. gets sun all day when the sun Is out. when can I expect flowers as when I purchased It It was allmost dead and was at the time in bloom. this Is the first jasmine plant I have had and need some healpful tips on keeping It healthy. thank you

    Leslie, if you can get your jasime untangled you could put it in a basket but I’m sure it will require some pruning which should be done after flowering. The vigorous grower can also be pruned during the growing season to control the shape and size. I would wait till early spring to do this. Jasminium polyanthum is a winter bloomer that needs 4-6 weeks of cool nighttime(no lower than 40 degrees) temperatures in order to set buds. Congratulations on your success with the plant.

    hi, reading through the comment section you had said that jasmine are acid lovers. I have my jasmine in regular miracle grow potting soil and have used the fertilizer sticks. there is no acid in my soil but the plant is growing like crazy. do I have a different jasmine plant other than the star or confederate. again I have a jasminum polyanthum.

    They like a slightly acid soil and your initial soil mix may have just the right ph for your plant(ph 5.8-6.0). It will tell you when it needs more acidic soil- the leaves will show symptoms of iron chlorosis (light colored leaves).

    first off thank you for you’re help with my jasmine polyanthum. It Is untangling very nicely. now since some of these vines are close to 6ft long how short do I prune them back? and Is It possible to root the cuttings and how Is this done. I haved moved It to a cooler location for part of the day and the other half It gets some sun. will a humidifier help out with xtra moister If I forget to mist? I have never seen such a happy camper. thank you again.

    I had to confer with Tom from Jamaican Gradens, (Ill) regarding how much you can trim off. The recommendation is 1/3 of the total length or 2-3 feet. Cut back no further than the semi-hardened stem with leaf joints. If you cut back to hardened wood, it will not resprout new growth. It is best prune after flowering and in late winter/early spring as the plant will be better prepared to recover from severe pruning. The cuttings can be rooted- use semi-ripe cuttings in summer. Clippings can be rooted in the springtime in a warm misting house with high humidity and fresh circulated air. As it is a tropical plant, it will love the added humidity indoors in the winter.

    I bought a small jasmine plant from the grocery store 2 years ago. It had small white fragrant flowers all over it. I have kept the plant, re-potted, and it is now a 4 ft. high viny trellis. I would love for it to be covered in those most wonderful smelling flowers. However, the last 2 spring seasons have brought only more vines. How can I make it bloom again?

    Some of the factors that can affect blooming are not enough sun-move it to more sun exposure, the type of fertilizer-if you give it too much Nitrogen(the first #) then you can get more green growth at the expense of flowers. Try a bloom-booster fertilizer. Some jasmines are seasonal bloomers and flower at certain times of the year.

    What brand of fertilizer would you recommend for pink jasmine? I found that the information on soil for pink jasmine was helpful, thats why I will be checking it. But if the soil is where it should be then I will be looking at the possiblity of iron chlorosis. Any help with what i should use will be appeciated.

    Fertilize Pink jasmine (J. polyanthum) during the growing season with a high phosphorous fertilizer (15-30-15) this will encourage blooming. Feed it every 2-3 weeks. If the plant is showing signs of iron chlorosis add chelated iron to the fertilizer. Check out Miracle Grow

  7. I bought a pink jasmine plant in March of 2006. It had beautiful fragrant flowers. I still have it and it is beautiful except it has not given me any flowers since March of last year. What do I need to do so it may bloom agian?
    Stella

    I believe you have a Jasmine polyanthum which is a winter bloomer that needs 4-6 wks of cool nighttime temperatures (40-50 degrees) from September to bud set. During this winter period water less only when the soil dries out. Sometimes lack of flowers is simply due to overfertilizing-too much nitrogen causing excessive leaves and no flowers or not enough light.

  8. I live in Santa Fe New Mexico. I purchased my jasmine plants a few months ago, and have them indoors facing my south windows. They are already blooming with white star-like flowers. Is it to early for them to be blooming? Also, how long do they bloom for? What kind of fertilizer do I use now that their in bloom? do I change the fertilizer in the the fall?

    I’m not sure what kind of Jasmine you have, but there is Jasminum polyanthum which does bloom in the winter as well as J.rex which blooms in fall/winter. Both are seasonal bloomers that respond to short day length and cold temperatures. At any rate, enjoy the flowers and fragrance. Polyanthum has a heavy , overpowering fragrance and a vigorous grower that can bloom for a month or more. You can fertilize contiually with a 10-10-10 or balanced fertilizer at 1/4 tsp per 1 gal of water. Be sure to periodically stop fertilizing and run clear water to prevent soluble salt buildup. Another alternative is to use slow-release fertilizer (Osmocote, etc) follow the manufacturers directions for the size pot.

  9. PLEASE ADVISE HOW TO ROOT PINK JASMINE?

    Best time to root is in summer or early fall. Use semi-hardwood cuttings 4-6 inches long, strip off the bottom leaves, dip the bottom 1/3 stem in rooting hormone and pot in a soil mix of peat/sand and perlite. Place pot in a plastic bag to create a greenhouse-opening periodicaly. If humid and warm weather you won’t need to keep in plastic bag. Place the cuttings in a shaded spot such as a porch or screened room. If you have extra cuttings, -some have had success rooting in water. Softwood tip cutting should be rooted in early summer. When the cuttings are rooted, let them grow until they have a good root system one season before transplanting in garden soil.

  10. I purchased a Sambac Jasmine about 6 months ago. It’s leggy but was blooming nicely (although the flowers bloomed near evening and feel off by morning). It hasn’t bloomed in months. The leaves are shiny and sticky and I discovered brown bumps on the stems. When I scrape them off they are sticky inside. Yesterday I discovered little white worms in the dirt. I live in NJ. The plant was outside for a part of the summer. It’s now inside, gets watered occasionally but is not “wet” and it’s in a western window which gets lots of sun during most of the daytime hours. help ! I really want to save this plant !

    Sounds like you have scale .(bumps) and the white worms can be the larval form of fungus gnats
