Botanical Name: Jasminum polyanthum
Chinese jasmine plant is surely among the most graceful of vining plants. Their long, wiry vines are densely covered with glossy, green leaves and fragrant star-shaped flowers.
Cool autumn air and plenty of light will bring a profusion of blooms in winter. Because you're growing jasmine indoors, this beautiful evergreen needs some help from you.
Give it plenty of sunshine and warmth in the summer months to help it grow. Then provide 6 weeks of cool temperatures in fall to set buds. Move your jasmine plant outdoors in the fall when the weather is cool, keeping it in partial shade. If you can't put it outdoors, keep it in a cool sunroom, brightly lit porch, or other cool room for this cool treatment.
Clusters of dark-pink, tubular flower buds arise from the leaf axils in late fall to early winter. The buds stay small until around February, when they will open into 5-petaled, white star-like flowers that are strongly scented, especially at night.
Pinch and Prune. Pinch stem tips during the growing season to encourage branching. After the flowers fade, prune it back harshly. Plants that aren't pruned back will eventually have bare lower stems as they shed old leaves.
Pruning tip: Prune back hard in spring or early summer to control its growth and to prevent it from becoming leggy. Take care to only remove the stems that have already flowered. Propagate stem tip cuttings, if you want, for more plants.
Repot in spring only when the roots have filled the pot. Jasmine plant blooms best when slightly pot-bound, so use a smallish container or you may see a lot of leaves and few flowers. Don't worry about pruning and repotting jasmine at the same time. It's pretty robust -- you won't hurt it at all.
Support your plant. Twining jasmine vines need support. You can easily train it around a hoop or over a small trellis inserted in the pot. You can tie it to the support with florist wire, if you need to. However, this vigorous climber doesn't need much training to twine around any type of support.
No flowers? This winter-blooming jasmine needs a cool treatment for 6 weeks in the fall to set buds. (See "Temperature" below.) This plant also needs bright light year-round.
Is Jasminium polyanthum poisonous? No, it is non-toxic. It is safe to have in a home with children and pets.
Something bugging your plant?
Aphids are attracted to soft, new growth, which jasmine has in abundance. Look for them on the foliage and along the stems.
Mealybugs seem to love Jasmine. If you see these white, cotton-like bugs, remove them with a cotton swab dipped in rubbing alcohol.
Spider mites are also possible pests, especially in winter when indoor air tends to be dry. They're so tiny, you'll likely only see their fine webbing between stems and foliage.
Isolate any infested plant to prevent pests from invading your other houseplants, and treat it right away. If your plant has already bloomed, prune off any infested stems.
Jasmine is a member of the olive family (Oleaceae), and includes about 200 species. Jasminum polyanthum is the easiest to grow indoors and has long been a popular house plant.
