Jasminum is a vining tropical plant that is primarily grown for its clusters of tubular, star-shaped flowers that are often sweetly fragrant. Jasminum commonly has rich, deep green lance-shaped leaflets often with shoots that will twine around supports.
Some Jasminum species will grow to 20 feet (6m) in tropical regions. Some species are mounding and shrub-like. Jasminum can be trained against support or can be allowed to trail across the ground. Jasminum can be grown on a trellis, fence, or arch. They can be allowed to run down a slope or over a wall.
Jasminum grows best in fertile, well-drained soil in full sun or partial shade. Jasminum should be protected from cool or constant breezes.
Jasminum is a genus of about 200 species of evergreen and semi-evergreen climbers and shrubs. Jasminum is native to woodland and scrub in tropical and temperate regions of Europe, Asia, and Africa.

How to Care for Jasminum
- Jasminum branches can be cut and easily forced into bloom indoors in midwinter.
- Since all Jasminum flowers form on previous season’s growth, not on current growth, all pruning should be done immediately after flowering.
- Jasminum plants can be pruned severely after flowering without greatly reducing the number of flowers the following season.
Growing Jasminum as a Houseplant
- Jasminum grandiflorum, J. nitidum, J. officinale, and J. polyanthum can be grown as houseplants.
- Jasminum prefers average temperature indoors, direct light, and average to high humidity.
- Grow in well-drained, soilless medium and keep the medium evenly moist during spring and summer. In fall and winter, allow the medium to dry slightly between waterings.
- Fertilize monthly during spring and summer
- After the plant has bloomed prune it back to 6 inches high.
- Provides plants with a trellis, wire hoop, or other support.
- Plants benefit from being placed outdoors in summer.
Jasminum Pests and Diseases
- Aphids, scale insects, and mealybugs can attack Jasminum.
- Root rot, fungal and bacterial leaf spots, and viruses can occur.
- Propagate Jasminum from softwood cuttings of young growth in late spring or early summer, from semihardwood cuttings or more mature growth in mid- or late summer, or from hardwood cuttings of dormant leafless growth in fall or winter.
- Jasminum can also be propagated by forcing a branch to grow roots by ground layering.
