Jasmine

Botanical Name Jasminum polyanthum
Family Oleaceae
Origin West China

Identification

Evergreen, climbing vine. Leaves opposite, compound with leaflets. Flowers white, tube-like, fragrant, Jan-Dec. Fruit glossy black with dark red pulp. The most common cultivated species in New Zealand.

Habitats

Forest margins, forest gaps, shrubland margins, general shrubland and forest, farm hedges, roadsides, abandoned houses and gardens, wasteland.

Impact to Biota and Ecosystems

Capacity to smother up to mid canopy level i.e. towai, taraire height. One plant can cover a large area spreading insidious runners, sometimes across inhospitable sites. In the open, jasmine may have a matting effect which inhibits seedling growth. Capacity to carpet forest margins and gaps.

Dispersal Routes, Vectors, Infestation Sources

Seedling growth has been observed in the natural environment but information on seed dispersal is unknown. Dispersal routes are mostly via the dumping of cuttings or as an escaped garden plant from abandoned sites. Seed bird palatable.

Management

Management 

Physical Control

Cut near ground level and remove all roots and stems.

Disposal

Compost or bury. Plant will resprout if mulched.

Chemical Control

(i) Tordon Brushkiller

Cut stem and paint roots with Tordon Brushkiller stump swab (knapsack or paintbrush). 1 part Tordon Brushkiller to 20 parts water. Liberally coat cut surface.

(ii) Metsulfuron mixed at 10 grams in 10 litres of water with 20 ml Penetrant

Cut plant and spray regrowth on ground several months later with Metsulfuron and Penetrant.

Biological Control

 
Recommended Approach

If the infestation is small or labour resource large, hand pulling and removal of vegetative material is most effective. Large infestations will require several applications of chemical.
