Scrambling, rhizomatous perennial groundcover/vine. Stems are trailing, layering, < 2 m long and contain milky latex. Leaves are < 10 x 7 cm. Flowers are solitary, blue/violet and < 5 cm in diameter.
To help protect our environment:
Riparian margins, alluvial flats, disturbed forest and scrubland, coastal areas, bare and rocky habitat, wasteland, roadsides.
Seed rarely set. Vegetative spread from stem layering and rhizomes, dispersed by water and soil movement. Human-mediated dispersal through dumping of garden waste and movement of contaminated soil and machinery.
Smothers ground vegetation, preventing native seedling regeneration. Alters erosion and flow regimes of streams. Vector for Pierce’s disease in grapes.
Follow up treated areas 3 times per year. Encourage natural regeneration of native plants or replant treated areas where possible after 2-3 treatments to establish dense ground cover and minimise reinvasion.
CAUTION: When using any herbicide or pesticide please read the label thoroughly to ensure that all instructions and safety requirements are followed.
