A Fragrant Climbing Genus
Jasmine, genus Jasminum, gathers together a range of woody climbers and shrubs grown for their often richly scented flowers. Some are hardy garden plants, others are tender and better suited to a warm room or conservatory. Jasminum polyanthum, the many-flowered jasmine covered here, is one of the tender kinds, prized indoors for its abundant white, sweetly perfumed blooms.

Out of Southwest China
Jasminum polyanthum comes originally from southwest China, in the Oleaceae family alongside the wider jasmine clan. It is a vigorous evergreen twining climber, capable of reaching four to eight metres given the room, though far more modest when kept in a pot indoors. In cooler climates it is grown chiefly under glass or as a houseplant, since it will not tolerate frost.

Light, Warmth, Moisture
Give this jasmine full sun to partial shade with plenty of bright, indirect light, ideally six to eight hours a day, and keep it away from direct sun and cold draughts alike. It favours warmth, doing best in daytime temperatures in the eighties Fahrenheit and nights in the seventies, which suits most centrally heated homes reasonably well. Check the top two inches of soil and water at the base when it has dried, and support humidity around fifty percent with misting or a nearby humidifier, since this is by origin an understorey plant of warm, humid regions. Feed with a diluted liquid fertiliser, monthly in warmth or every six weeks once temperatures dip below seventy degrees, easing off through late summer and into winter.

Cuttings or Layering
The RHS recommends propagating this jasmine from semi-ripe cuttings taken in summer, or by layering in autumn. Indoors, cuttings from the previous season's growth work well: trim a length below a leaf node, strip away all but the top three leaves and any flower buds, then dip it in water and rooting hormone before setting it in potting mix out of direct light. New growth within a couple of weeks signals success.

Pink Buds, White Blooms
This is a vigorous, evergreen twiner with dark green leaves made up of as many as seven lance-shaped leaflets. Its real draw is the flower: long-tubed white blooms about two centimetres across, opening from pink buds in clusters up to ten centimetres long. Outdoors in frost-free climates these appear from late spring, but in a warm greenhouse or conservatory they can open earlier in the year.

Watch for Sap Feeders
Grown under glass or indoors, this jasmine can attract aphids, scale insects and mealybugs, all sap-feeding pests worth checking for regularly since early spotting makes treatment easier. Mealybugs in particular can be wiped off by hand with a cotton swab dipped in rubbing alcohol, followed by continued monitoring in case any are hiding elsewhere on the plant.

Few Blooms, Stressed Leaves
A plant with plenty of dark leaves but few flowers usually points to a fertiliser too high in nitrogen relative to potassium and phosphorus, so switching to a bloom-friendly feed is the usual fix. Both under- and over-watering bring on stress that leaves the plant open to disease, so let the top two inches of soil guide watering, and if leaves are drying out from low humidity, step up misting.

Thin After Flowering
Once flowering has finished, thin out overcrowded growth, and under glass it may need a bit of restrictive pruning to keep it in bounds. It is grown in a container with peat-free, loam-based compost, positioned in bright filtered light, and can be moved outdoors in frost-free areas with shelter and full sun or part shade.
