Coffee Senna (Senna occidentalis)
Coffee senna plant
Coffee senna is declared a Class B (spread to be controlled) and Class C (not to be introduced to the Northern Territory) weed in accordance with the NT Weeds Management Act 2001.
Coffee senna can adversely impact native pastures, by successfully competing for moisture light and nutrients and consequently lowering grazing capacities. Although there have been no documented cases, coffee senna is thought to be toxic to cattle. Grain contaminated with the toxic seed should not be fed to livestock, including poultry.
