Family: Oleaceae
Origin, Description & Uses:
Jasminum grandiflorum, commonly known as Spanish jasmine, is native to a broad region spanning East Africa (from Eritrea to Rwanda), the Arabian Peninsula, and parts of Asia from Pakistan to south-central China. It is a fast-growing, semi-evergreen shrub or vine with slender stems and pinnate leaves, producing clusters of large, star-shaped white flowers with a rich, sweet fragrance. Highly valued for its scent, Spanish jasmine is widely cultivated in tropical and subtropical regions as an ornamental plant and is especially prized in the perfume industry, where its blossoms are used to produce jasmine absolute. It is also grown in gardens for trellises, hedges, and container planting, and has a history of use in traditional medicine and cultural practices.
Risks & Threats:
Spanish jasmine is considered a low-risk species for Hawaiʻi. While it can spread vegetatively and by seed under favorable conditions, it is not known to be invasive in the islands and typically remains confined to cultivated areas. It does not exhibit aggressive growth or the ability to outcompete native vegetation in natural ecosystems. As with many ornamental plants, occasional monitoring is recommended to ensure it does not escape cultivation, but overall it poses minimal ecological threat and is unlikely to negatively impact Hawaiʻi’s native habitats.
High Risk Traits:
- Reproduces vegetatively (suckers)
- Self-compatible or apomictic
- Intentionally dispersed by people (ornamental, oil)
- Bird-dispersed (fleshy berries)
- Tolerates wide soil types and pH
- Fast-growing, evergreen climbing vine
- Produces viable seed
- Flowers in 6 months (short generation time)
Low Risk Traits:
- No confirmed naturalization
- Not a weed of agriculture, forestry, or natural areas
- No spines, thorns, or burrs
- Non-toxic
- Low seed set (high pollen sterility)
- No prolific seed production
- No persistent seed bank known
- No wind or water dispersal
- No allelopathic effects
