Jasmine polyanthum

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 vine 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. It can be grown outdoors year round in zone 9 and up.

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.

Bloom set
J. polyanthum is a seasonal bloomer that will set bud when exposed to temperatures below 40-60 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 and treat it like a houseplant. Place your jasmine in bright filtered light and keep the soil slightly moist but not soggy.  Provide increased humidity during the winter by placing the plant on a pebble tray . Once the flower buds are set, move  it in a sunny bright, cool location.  J. polyanthum requires less water in the winter.

To control the vigorous growth, Jasmine needs frequent pinching. Cut the plant back after blooming and during 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.


Spider mites, aphids, mealy bugs 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.
