General description

Much-branched, spiny evergreen, scrambling perennial herb. Hairless stems have numerous branchlets with 10mm long spines. Thick mat of tuberous roots. Thin green leaves with distinctive midribs. Small white flowers (Oct-Mar). Red berries.

Sand dunes, coastal scrublands, low forest, roadsides, forest margins. Prefers warm- temperate climate, light infertile soils, in shade or open understorey.

Seeds dispersed by birds. Vegetative spread if rhizomes & tubers dumped.

Forms mass of aerial stems & foliage, suppressing other species. Prevents regeneration. Spiny nature impedes movement.

Site management

Maintain rolling front of control. Always follow up on treated areas at least 6 monthly. Replant treated areas where possible after 2-3 treatments to establish dense ground cover & minimise reinvasion.

Recommended approaches

1. Grub out small infestations removing all rhizomes.
2. Weed wipe spring -summer (300ml glyphosate/1L, no penetrant).
3. Spray lightly spring-early summer (200ml glyphosate/10L. Do not add penetrant when spraying against tree trunks).

Caution: when using any herbicide or pesticide PLEASE READ THE LABEL THOROUGHLY to ensure that all instructions and safety requirements are followed.
