What does it look like?

Slender scrambling or climbing perennial with tuberous roots, and long green, thin, wiry stems (2-4 m long) that are much branched at the top. Leaves ((5-15 mm x 1-1.5 mm) are flat cladodes (leaf-like structures, resembling miro), and are usually in groups of three at each node. Tiny whitish flowers appear from September to December and are followed from October to February by round berries (8 mm diameter) that ripen from green to orange-red and contain 1-2 seeds each.

Why is it a problem?

Forms dense patches on ground or sub-canopy in most forest types, has tough, long-lived tubers that resprout easily, moderate growth rate and well dispersed seeds. Tolerates moderate to heavy shade, most soil types, moderate to high rainfall, and hot to cold temperatures

Smothers forest floor and understorey to 4 m, preventing the establishment of native plant seedlings and growth of established species. Raises light levels, causing the invasion of further weeds. Can ringbark and kill soft-barked shrubs and trees, and invades areas where epiphytes are usually found, replacing already vulnerable species.

Control Methods

Physical control

Maintain rolling front of control, work out from inner bush.

  • Dig out tubers. Dispose of at a refuse transfer station, burn or bury. Other plant material can be left on site to rot down.

Herbicde control

  •  Weed-wipe 300mls glyphosate per litre water. Total coverage is not required; or
  • Spray with 200mls glyphosate (360g/l e.g. Round-up®) per 10 litres water. Do not add penetrant if spraying against tree trunks.
