General Biology. Growth form. Shrub. Reproduction. Stem fragments. Dispersal. Water, garden refuse. Toxicity. Can cause throat allergies in humans. Vegetative regeneration strategy. Resprouts, produces root suckers, stem layering, broken stems. Woody structure. Ring porous/diffuse porous. Seedbank persistence. No seed set recorded in Australia. Fire response. Resprouts rapidly after fire.

Suggested method of management and control. Hand pull small plants removing all stem material. For stems greater than 7 cm diameter, apply 250 ml Access® in 15 L of diesel to basal 50 cm of stem (basal bark) or cut and paint with 50% glyphosate. Read the manufacturers' labels and material safety data sheets before using herbicides. For further information consult the Australian Pesticides and Veterinary Medicines Authority to determine the status of permits for your situation or state.
