What does it look like?

Vigorous, evergreen, high-climbing vines grows up to 10 metres high with long, densely hairy stems which are angular when young, and which have many spiralling tendrils. Leaves are 3-lobed (each lobe 5-14 cm long) with middle lobe the longest, edges serrated, and undersides covered in down. From Jan-Dec pink hanging flowers (7 cm diameter) with central tube (60-95 mm long) appear, followed by hanging, thin-skinned fruit (7- 12 x 2-4 cm) ripening from green to yellow or orange, with sweet edible orange pulp and dark red seeds (4-6 mm long).

Prefers disturbed and open forest, light wells and margins of intact bush, streamsides, coastline, cliffs, consolidated sand dunes, inshore islands.

Why is it a problem?

Grows to medium-high canopy, where it forms large masses. Grows rapidly in most soil types, and produces highly viable seed in 2 years. Partly tolerant to shade, damage and drought, and stems root where they touch the ground.

Where established, this plant will smother tree canopies, preventing recruitment and regeneration. Allows faster-growing or tougher vines to succeed it in dominating canopy. Appears in light wells away from parent plant.

Control Methods

Herbicides

  • Cut and stump treat larger stems (within 10 minutes of cutting) with 1g metsulfuron-methyl (600g/kg e.g. Escort®) per 1 litre water; or 200mls glyphosate (360g/l e.g. Roundup ®) per litre water; or
  • Spray masses on the ground where roots can’t be pulled, with 30mls triclopyr (300g/l e.g. Grazon®) + 20mls penetrant per 10 litres water or 100ml glyphosate and 20mls penetrant per 10 litres water.
