Evergreen climber up to mid canopy height, twines around host. Opposite, compound leaves, 7 leaflets, small, shiny, dark green when mature; new growth red-tinged. Masses of highly scented, small white tubular flowers in spring; some flowers present all year round. Glossy black fruit with dark red pulp.
Forest margins, & gaps, shrubland, roadsides. Tolerates frost, shade, moisture.
Main spread via garden escapes or dumped garden refuse. Very rapid growth from stem fragments. Seed dispersal by birds.
Forms impenetrable groundcover, smothers all vegetation to mid-canopy level. Alters forest composition, suppresses regeneration.
Many plants do not produce seed. Once established is hard to kill & dispose of. Most infestations will require several herbicide applications.
1. Prune vines as close to original stem as possible, then paint cut stem (5g metsulfuron + 1ml penetrant/1L or 250ml 2,4-D plus dicamba + 10ml penetrant/1L). Remove all cut stems.
2. In summer, vial treatment good for ground infestations. Pull up all stems possible & dispose. Treat remainder by placing vines in vials 5-10m apart (metsulfuron 1g/20ml). Move monthly.
3. Cut back & spray regrowth in summer (5g metsulfuron+10ml penetrant/10L or 2,4-D plus dicamba + 10ml penetrant/10L).
Caution: when using any herbicide or pesticide PLEASE READ THE LABEL THOROUGHLY to ensure that all instructions and safety requirements are followed.
